标签:ssh struts2 spring hibernate maven2
这篇主要采用Maven搭建Spring+Struts2+Hibernate的整合项目,复习一下SSH框架,虽然spring提供自己的MVC框架,但是Spring也提供和其他框架的无缝整合,采用组件形式对个框架进行管理,项目实例是按照真实企业里面的开发搭建,也是web的最后一片了。数据库使用mysql,连接池使用的是Druid数据源(这些都无关紧要,可以随时的替换),下面就将详细的介绍一下Maven搭建Spring,Struts2,和hibernation的步奏。
数据库库表很简单,设计好数据库后,直接逆向生成实体,提高速度。数据库名为shop,只有一个表user_info。其结构如下:
创建maven项目,pom.xml配置中引入所需依赖包。
引入所需的依赖包,pom.xml内容如下:

以上就是ssh所需的所有依赖包。、
最优先引入的是Spring框架,他是管理其他框架的容器,spring中需要配置的是自动扫描的dao,和service层的注解,然后将其注入为bean,管理。
配置文件在src/main/java目录下,创建spring的配置文件spring.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd"> <!-- 加载配置文件 --> <context:property-placeholder location="classpath:config.properties"/> <!-- 扫描service自动注入为bean --> <context:component-scan base-package="org.andy.shop.service.impl,org.andy.shop.dao.impl" /> </beans>
log4j.properties配置内容如下:
### set log levels ### log4j.rootLogger = INFO , C , D , E ### console ### log4j.appender.C = org.apache.log4j.ConsoleAppender log4j.appender.C.Target = System.out log4j.appender.C.layout = org.apache.log4j.PatternLayout log4j.appender.C.layout.ConversionPattern = [spring_struts2_Hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n ### log file ### log4j.appender.D = org.apache.log4j.DailyRollingFileAppender log4j.appender.D.File = ../logs/spring_struts2_Hibernate_demo.log log4j.appender.D.Append = true log4j.appender.D.Threshold = INFO log4j.appender.D.layout = org.apache.log4j.PatternLayout log4j.appender.D.layout.ConversionPattern = [spring_struts2_Hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n ### exception ### log4j.appender.E = org.apache.log4j.DailyRollingFileAppender log4j.appender.E.File = ../logs/spring_struts2_Hibernate_demo_error.log log4j.appender.E.Append = true log4j.appender.E.Threshold = ERROR log4j.appender.E.layout = org.apache.log4j.PatternLayout log4j.appender.E.layout.ConversionPattern = [spring_struts2_Hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n
添加项目的配置文件config.properties,有spring管理。
#application configs #jdbc druid config validationQuery = SELECT 1 jdbc.url = jdbc:mysql://localhost:3306/shop?useUnicode=true&characterEncoding=utf-8 jdbc.username = root jdbc.password = root #hibernate config hibernate.dialect = org.hibernate.dialect.MySQLDialect hibernate.show_sql = true hibernate.format_sql = false hibernate.hbm2ddl.auto = update
Hibernation的配置主要有如下内容:数据源,SessionFactory,事务等的配置。
spring-hibernate.xml配置如下(配置文件名可以随便起)
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd"> <!-- 配置数据源 使用的是Druid数据源 --> <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <!-- 初始化连接大小 --> <property name="initialSize" value="0" /> <!-- 连接池最大使用连接数量 --> <property name="maxActive" value="20" /> <!-- 连接池最小空闲 --> <property name="minIdle" value="0" /> <!-- 获取连接最大等待时间 --> <property name="maxWait" value="60000" /> <property name="poolPreparedStatements" value="true" /> <property name="maxPoolPreparedStatementPerConnectionSize" value="33" /> <!-- 用来检测有效sql --> <property name="validationQuery" value="${validationQuery}" /> <property name="testOnBorrow" value="false" /> <property name="testOnReturn" value="false" /> <property name="testWhileIdle" value="true" /> <!-- 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒 --> <property name="timeBetweenEvictionRunsMillis" value="60000" /> <!-- 配置一个连接在池中最小生存的时间,单位是毫秒 --> <property name="minEvictableIdleTimeMillis" value="25200000" /> <!-- 打开removeAbandoned功能 --> <property name="removeAbandoned" value="true" /> <!-- 1800秒,也就是30分钟 --> <property name="removeAbandonedTimeout" value="1800" /> <!-- 关闭abanded连接时输出错误日志 --> <property name="logAbandoned" value="true" /> <!-- 监控数据库 --> <property name="filters" value="mergeStat" /> </bean> <!-- 配置hibernate的SessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <!-- 注入数据源 相关信息看源码 --> <property name="dataSource" ref="dataSource" /> <!-- hibernate配置信息 --> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${hibernate.dialect}</prop> <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> <prop key="hibernate.format_sql">${hibernate.format_sql}</prop> <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop> </props> </property> <!-- 扫描hibernate注解配置的entity --> <property name="packagesToScan" value="org.andy.shop.entity" /> </bean> <!-- 配置事务管理器 --> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <!-- 配置事务增强处理Bean,指定事务管理器 --> <tx:advice id="transactionAdvice" transaction-manager="transactionManager"> <!-- 配置详细事务处理语义 --> <tx:attributes> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="get*" propagation="SUPPORTS" read-only="true" /> <tx:method name="find*" propagation="SUPPORTS" read-only="true" /> <tx:method name="select*" propagation="SUPPORTS" read-only="true" /> <tx:method name="load*" propagation="SUPPORTS" read-only="true" /> <!-- 其他采用默认事务方式 --> <tx:method name="*" /> </tx:attributes> </tx:advice> <!-- Spring aop事务管理 --> <aop:config> <!-- 配置切入点 --> <aop:pointcut id="transactionPointcut" expression="execution(* org.andy.shop.service.impl.*Impl.*(..))" /> <!-- 指定在txAdvice切入点应用txAdvice事务增强处理 --> <aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" /> </aop:config> </beans>
注意:Hibernation4使用的是SessionFactory而不是HibernationTemplate。
我们先添加实体entity,Dao,Service,Action等几个包,一般设计如下:
设计好数据表之后,采用Hibernation tools自动逆向生成实体,其实体UserInfo如下:
package org.andy.shop.entity; // Generated 2015-2-13 12:48:39 by Hibernate Tools 4.0.0 import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.Id; import javax.persistence.Table; /** * UserInfo generated by hbm2java */ @Entity @Table(name = "user_info", catalog = "shop") public class UserInfo implements java.io.Serializable { /** * */ private static final long serialVersionUID = 5127853981202454040L; private int id; private String name; private Integer age; private String telephone; public UserInfo() { } public UserInfo(int id, String name) { this.id = id; this.name = name; } public UserInfo(int id, String name, Integer age, String telephone) { this.id = id; this.name = name; this.age = age; this.telephone = telephone; } @Id @Column(name = "id", unique = true, nullable = false) public int getId() { return this.id; } public void setId(int id) { this.id = id; } @Column(name = "name", nullable = false) public String getName() { return this.name; } public void setName(String name) { this.name = name; } @Column(name = "age") public Integer getAge() { return this.age; } public void setAge(Integer age) { this.age = age; } @Column(name = "telephone") public String getTelephone() { return this.telephone; } public void setTelephone(String telephone) { this.telephone = telephone; } }
我们采用面向接口编程,所以先设计接口,在写dao的实现类,其理,同样适用于service层。
我们先定义一个通用的GenericDao接口,如下:
package org.andy.shop.dao; import java.io.Serializable; import java.util.List; /** * 创建时间:2015-2-11 下午2:26:42 * * @author andy * @version 2.2 * * Dao通用接口 */ interface GenericDao<T, PK extends Serializable> { T load(PK id); T get(PK id); List<T> findAll(); void persist(T entity); PK save(T entity); void saveOrUpdate(T entity); void delete(PK id); void flush(); }
具体的UserInfo的Dao接口UserInfoDao如下:
package org.andy.shop.dao; import org.andy.shop.entity.UserInfo; /** * 创建时间:2015-2-13 下午12:49:55 * @author andy * @version 2.2 * 描述: userDao */ public interface UserInfoDao extends GenericDao<UserInfo, Integer> { }
UserInfo的Dao层实现类UserInfoDaoImpl如下:
package org.andy.shop.dao.impl; import java.util.List; import org.andy.shop.dao.UserInfoDao; import org.andy.shop.entity.UserInfo; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Repository; /** * 创建时间:2015-2-13 下午12:51:47 * * @author andy * @version 2.2 * 描述: dao实现类 */ @Repository("userInfoDao") public class UserInfoDaoImpl implements UserInfoDao { @Autowired private SessionFactory sessionFactory; private Session getCurrentSession() { return this.sessionFactory.getCurrentSession(); } @Override public UserInfo load(Integer id) { return (UserInfo) this.getCurrentSession().load(UserInfo.class, id); } @Override public UserInfo get(Integer id) { return (UserInfo) this.getCurrentSession().get(UserInfo.class, id); } @SuppressWarnings("unchecked") @Override public List<UserInfo> findAll() { List<UserInfo> userInfos = this.getCurrentSession() .createQuery("from UserInfo").list(); return userInfos; } @Override public void persist(UserInfo entity) { this.getCurrentSession().persist(entity); } @Override public Integer save(UserInfo entity) { return (Integer) this.getCurrentSession().save(entity); } @Override public void saveOrUpdate(UserInfo entity) { this.getCurrentSession().saveOrUpdate(entity); } @Override public void delete(Integer id) { UserInfo entity = this.load(id); this.getCurrentSession().delete(entity); } @Override public void flush() { this.getCurrentSession().flush(); } }
Service层同理按照面向接口编程。
UserInfo层接口UserInfoService如下:
package org.andy.shop.service; import java.util.List; import org.andy.shop.entity.UserInfo; /** * 创建时间:2015-2-13 下午1:00:51 * @author andy * @version 2.2 * 描述: */ public interface UserInfoService { UserInfo load(Integer id); UserInfo get(Integer id); List<UserInfo> findAll(); void persist(UserInfo entity); Integer save(UserInfo entity); void saveOrUpdate(UserInfo entity); void delete(Integer id); void flush(); }
service层我们使用@Service注解将其注入为bean。
package org.andy.shop.service.impl; import java.util.List; import org.andy.shop.dao.UserInfoDao; import org.andy.shop.entity.UserInfo; import org.andy.shop.service.UserInfoService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; /** * 创建时间:2015-2-13 下午1:03:47 * * @author andy * @version 2.2 描述: */ @Service("userInfoService") public class UserInfoServiceImpl implements UserInfoService { @Autowired private UserInfoDao userInfoDao; @Override public UserInfo load(Integer id) { return null; } @Override public UserInfo get(Integer id) { return userInfoDao.get(id); } @Override public List<UserInfo> findAll() { return userInfoDao.findAll(); } @Override public void persist(UserInfo entity) { userInfoDao.persist(entity); } @Override public Integer save(UserInfo entity) { return userInfoDao.save(entity); } @Override public void saveOrUpdate(UserInfo entity) { userInfoDao.saveOrUpdate(entity); } @Override public void delete(Integer id) { userInfoDao.delete(id); } @Override public void flush() { userInfoDao.flush(); } }
以上,spring和Hibernation框架就算是整合完成了,我们需要测试一下是否整合成功,事务是否起作用等,所以我们需要在src/test/java源目录中编写测试类,进行测试:
我们创建了TestUserService类,进行单元测试:
TestUserService内容如下:
package org.andy.shop.service; import org.andy.shop.entity.UserInfo; import org.apache.log4j.Logger; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import com.alibaba.fastjson.JSON; /** * 创建时间:2015-2-13 下午3:31:07 * * @author andy * @version 2.2 */ @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = { "classpath:spring.xml", "classpath:spring-hibernate.xml" }) public class TestUserService { private static final Logger LOGGER = Logger .getLogger(TestUserService.class); @Autowired private UserInfoService userInfoService; @Test public void save() { UserInfo userInfo = new UserInfo(); userInfo.setName("zty"); userInfo.setAge(23); userInfo.setTelephone("13212221333"); Integer id = userInfoService.save(userInfo); JSON.toJSONString(id); } }
我们需要引入springjunit的包,将spring配置加载,如果单元测试成功,那么项目搭建已经成功了一半了。
配置Struts框架的配置文件,Struts2不同于前面的框架,其配置文件名必须为struts.xml,内容如下:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <!-- 指定由spring负责action对象的创建 --> <constant name="struts.objectFactory" value="spring" /> <!-- 所有匹配*.action的请求都由struts2处理 --> <constant name="struts.action.extension" value="action" /> <!-- 是否启用开发模式 --> <constant name="struts.devMode" value="true" /> <!-- struts配置文件改动后,是aa否重新加载 --> <constant name="struts.configuration.xml.reload" value="true" /> <!-- 设置浏览器是否缓存静态内容 --> <constant name="struts.serve.static.browserCache" value="false" /> <!-- 请求参数的编码方式 --> <constant name="struts.i18n.encoding" value="utf-8" /> <!-- 每次HTTP请求系统都重新加载资源文件,有助于开发 --> <constant name="struts.i18n.reload" value="true" /> <!-- 文件上传最大值 --> <constant name="struts.multipart.maxSize" value="104857600" /> <!-- 让struts2支持动态方法调用 --> <constant name="struts.enable.DynamicMethodInvocation" value="true" /> <!-- Action名称中是否还是用斜线 --> <constant name="struts.enable.SlashesInActionNames" value="false" /> <!-- 允许标签中使用表达式语法 --> <constant name="struts.tag.altSyntax" value="true" /> <!-- 对于WebLogic,Orion,OC4J此属性应该设置成true --> <constant name="struts.dispatcher.parametersWorkaround" value="false" /> <!-- 用于CRUD Action的parent package --> <package name="crud-default" extends="convention-default"> <!-- 基于paramsPrepareParamsStack, 增加store interceptor保证actionMessage在redirect后不会丢失 --> <interceptors> <interceptor-stack name="crudStack"> <interceptor-ref name="store"> <param name="operationMode">AUTOMATIC</param> </interceptor-ref> <interceptor-ref name="paramsPrepareParamsStack" /> </interceptor-stack> </interceptors> <default-interceptor-ref name="crudStack" /> </package> <!-- 使用Convention插件,实现约定大于配置的零配置文件风格. 特殊的Result路径在Action类中使用@Result设定. --> </struts>
上面配置的比较详细,可以按照实际项目,做一下筛检。
web.xml是web项目的核心,里面配置了容器启动是的加载文件,以及监听器,过滤器等内容,所以需要我们配置对个框架的启动,加载。其内容如下:
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>spring_struts2_Hibernate_demo</display-name> <!-- spring 和 Hibernate的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath:spring.xml classpath:spring-hibernate.xml </param-value> </context-param> <!-- 编码设置 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>utf-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- openSessionInView配置 作用是延迟session关闭到view层 --> <filter> <filter-name>openSessionInViewFilter</filter-name> <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class> <init-param> <param-name>singleSession</param-name> <param-value>true</param-value> </init-param> </filter> <!-- 监听servletContext,启动contextConfigLocation中的spring配置信息 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止spring内存溢出监听器 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- Struts2 filter --> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> <filter-mapping> <filter-name>openSessionInViewFilter</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> <!-- 配置session超时时间,单位分钟 --> <session-config> <session-timeout>30</session-timeout> </session-config> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> </web-app>
控制层Struts2我们采用annotation 约束注解方式实现action的零配置,需要我们在WEB-INF下创建content目录(必须是content),里面存放是视图层jsp。
UserinfoAction内容如下:
package org.andy.shop.action; import java.util.List; import org.andy.shop.entity.UserInfo; import org.andy.shop.service.UserInfoService; import org.andy.shop.utils.AjaxUtil; import org.apache.log4j.Logger; import org.apache.struts2.ServletActionContext; import org.apache.struts2.convention.annotation.Namespace; import org.springframework.beans.factory.annotation.Autowired; import com.opensymphony.xwork2.ActionSupport; import com.opensymphony.xwork2.ModelDriven; import com.opensymphony.xwork2.Preparable; /** * 创建时间:2015-2-13 下午2:49:22 * * @author andy * @version 2.2 描述: user的Action */ @Namespace("/user") public class UserinfoAction extends ActionSupport implements ModelDriven<UserInfo>, Preparable { private static final long serialVersionUID = -2301203156032690317L; private static final Logger LOGGER = Logger.getLogger(UserinfoAction.class); private Integer id; private UserInfo userInfo; private List<UserInfo> userInfos; @Autowired private UserInfoService userInfoService; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public UserInfo getUserInfo() { return userInfo; } public void setUserInfo(UserInfo userInfo) { this.userInfo = userInfo; } public List<UserInfo> getUserInfos() { return userInfos; } public void setUserInfos(List<UserInfo> userInfos) { this.userInfos = userInfos; } @Override public UserInfo getModel() { if (null != id) { userInfo = userInfoService.get(id); } else { userInfo = new UserInfo(); } return userInfo; } @Override public String execute() throws Exception { LOGGER.info("查询所有用户"); userInfos = userInfoService.findAll(); return SUCCESS; } public void detail() { String id = ServletActionContext.getRequest().getParameter("id"); LOGGER.info("查看用户详情:" + id); userInfo = userInfoService.get(Integer.valueOf(id)); AjaxUtil.ajaxJSONResponse(userInfo); } @Override public void prepare() throws Exception { } }
按照约束原则,上面success是会跳转到content下的/user/userinfo.jsp视图。
注意:如果上述的UserinfoAction写出了UserInfoAction,那么对应的视图为/user/user-info.jsp,对应的Action为user-info.action
视图userinfo.jsp内容如下:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%> <% String path = request.getContextPath(); String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/"; %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <base href="<%=basePath%>" /> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <script type="text/javascript" src="js/jquery-1.9.1.min.js"></script> <title>userInfo</title> </head> <body> 全部用户信息: <c:forEach items="${ userInfos}" var="user"> <div> 姓名:${user.name } 年龄:${user.age } 电话: ${user.telephone } <a target="_blank" href="user/userinfo!detail.action?id=${user.id}">json详情</a></div> </c:forEach> </body> </html>
通过这个视图,我们可以测试UserinfoAction中的两个url。
使用Maven打包部署:clean compile package
测试 http://localhost:8080/spring_struts2_Hibernate_demo/user/userinfo.action
json返回数据 http://localhost:8080/spring_struts2_Hibernate_demo/user/userinfo!detail.action?id=1
OK,到此为止Spring+Struts2+Hibernate全部搭建完成。
