在网上看到好多个版本,自己有时间索性就写个Demo记录下整个框架的逻辑流程;
1、首先拷贝整个框架所需要的jar包到WEB-INF/lib包下(这个网上都可以搜到的)
2、配置文件的配置,
2.1、在web.xml配置文件中,是整个项目的入口配置文件,需要配置struts核心配置、Spring核心配置、监听spring配置
1 <!-- springframework config files --> 2 <context-param> 3 <param-name>contextConfigLocation</param-name> 4 <!-- 把spring的配置文件放到了/WEB-INF/下的springframework包里,方便统一管理,命名规则是以applicationContent-开头的xml文件,初始化时会自动搜索所有符合规则的配置文件 --> 5 <param-value>/WEB-INF/spring/applicationContext-web.xml</param-value> 6 </context-param> 7 8 <listener> <!--监听器 用于初始化spring框架 --> 9 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 10 </listener> 11 12 13 <!-- struts2模块 --> 14 <filter> 15 <filter-name>struts2</filter-name><!-- 这个就是struts2的核心过滤器 --> 16 <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> 17 </filter> 18 19 <filter-mapping> 20 <filter-name>struts2</filter-name> 21 <url-pattern>/*</url-pattern> 22 </filter-mapping>
2.2、将struts2的主配置文件复制到此项目中,可以复制到(classpath:)src的目录下即可
<struts>
<constant name="struts.objectFactory" value="spring" />
<constant name="struts.i18n.encoding" value="UTF-8" />
<constant name="struts.i18n.reload" value="false" />
<constant name="struts.configuration.xml.reload" value="false" />
<constant name="struts.custom.i18n.resources" value="globalMessages" />
<constant name="struts.action.extension" value="action,," />
<constant name="struts.convention.package.locators.basePackage"
value="com.hsinghsu.testSSI.action" />
<constant name="struts.convention.result.path" value="/" />
<constant name="struts.serve.static" value="true" />
<constant name="struts.serve.static.browserCache" value="false" />
<package name="default" namespace="/" extends="struts-default"> <!-- userAction --> <action name="register" class="com.test.action.RegisterAction" method="addUser"> <result name="success">index.jsp</result> <!-- 注册成功 --> <result name="input">register.jsp</result><!-- 注册失败 --> </action> </package> </struts>
2.3、Spring框架的搭建,创建applicationContext-web.xml配置文件,
<?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" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> <!-- 配置数据源,连接池采用的是c3p0,具体各参数代表意义参看c3p0自带的doc, --> <!--dataSource的相关配置 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <property name="driverClass" value="${jdbc.driverClassName}" /> <property name="jdbcUrl" value="${jdbc.url}" /> <property name="user" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> </bean> <!-- 上面的数据源的value值用的是表达式,原因就在这里,这将配置文件放到了iBatis目录下,也就是jdbc.properties,设置了c3p0的各项参数 --> <bean id="propertyConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location"><value>/WEB-INF/ibatis/jdbc.properties</value></property> </bean> <!-- 配置iBatis的sqlMapClient,这里交给了spring去处理,其中SqlMapConfig文件放到了WEB-INF的iBatis目录下,也是便于管理 --> <!-- Spring整合ibatis配置文件,注入sqlMapClient --> <bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean"> <property name="configLocation"><value>/WEB-INF/ibatis/SqlMapConfig.xml</value></property> <property name="dataSource"><ref bean="dataSource" /></property><!-- 这里使用的数据源就是上面配置的数据源 --> </bean> <!--user的相关操作配置 --> <bean id="userdaoImpl" class="com.test.daoImpl.UserDaoImpl"> <property name="sqlMapClient" ref="sqlMapClient"></property> </bean> <bean id="userServiceImpl" name="userServiceImpl" class="com.test.serviceImpl.UserServiceImpl"> <property name="userdao" ref="userdaoImpl"> </property> </bean> <!-- 用户注册action --> <bean id="registerAction" name="registerAction" class="com.test.action.RegisterAction" scope="prototype"> <property name="userService" ref="userServiceImpl"></property> </bean> <!-- 添加扫描、自动注解的配置--> <context:annotation-config /> <context:component-scan base-package="com.test" />
2.4、连接数据库的相关配置文件jdbc.properties和SqlMapConfig.xml配置文件(分别集中到一个文件夹中,)
jdbc.properties
jdbc.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver jdbc.url=jdbc:sqlserver://localhost:1433;DatabaseName=fdx jdbc.username=sa jdbc.password=abc123456
SqlMapConfig.xml【sql的映射文件的配置】
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE sqlMapConfig PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-config-2.dtd"> <sqlMapConfig> <!-- 用户信息表 --> <sqlMap resource="com/test/ibatis/sqlMap/User.xml" />
</sqlMapConfig>
User.xml配置文件中放的具体的sql语句的操作:
<sqlMap> <typeAlias alias="User" type="com.test.pojo.User" /> <!-- 保存注册信息 --> <insert id="insertUser" parameterClass="User"> insert into [fdx].[dbo].[User] (name,pass,username,address)values(#name#,#pass#,#username#,#address#) </insert>
<select>......</select>
</sqlMap>
以上都是配置文件的配置,接下来是部分java代码部分
dao接口
1 package com.test.dao; 2 3 import com.test.pojo.User; 4 5 public interface UserDao { 6 //用户注册 7 public boolean insertUser(User user); 8 }
daoImpl实现类
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport; import com.test.dao.UserDao; import com.test.pojo.User; public class UserDaoImpl extends SqlMapClientDaoSupport implements UserDao{ @Override public boolean insertUser(User user) { // TODO Auto-generated method stub try { System.out.println("111111:"+user.getId()+user.getAddress()); getSqlMapClientTemplate().insert("insertUser", user);
//直接调用封装好的增删改查方法return true; } catch (Exception e) { // TODO: handle exception e.printStackTrace(); return false; } } }
service接口
package com.test.service; import com.test.pojo.User; public interface UserService { //注册服务 public boolean insertUser(User user); //根据name查看用户信息 public User queryUserByName(String name); }
serviceImpl实现类【业务实现类】
package com.test.serviceImpl; import org.springframework.beans.factory.annotation.Autowired; import com.test.dao.UserDao; import com.test.pojo.User; import com.test.service.UserService; public class UserServiceImpl implements UserService{ @Autowired//【自动注解的注入】 private UserDao userdao; public UserDao getUserdao() { return userdao; } public void setUserdao(UserDao userdao) { this.userdao = userdao; } @Override public boolean insertUser(User user) { // TODO Auto-generated method stub System.out.println("进入到service实现类中"+user.getAddress()+":地址"); return userdao.insertUser(user); }
}
RegisterAction类
public class RegisterAction extends ActionSupport implements ServletRequestAware{ /** * 序列化 */ private static final long serialVersionUID = 1L; @Autowired private UserService userService; public UserService getUserService() { return userService; } public void setUserService(UserService userService) { this.userService = userService; } private HttpServletRequest request;
@Override
public void setServletRequest(HttpServletRequest arg0) {
// TODO Auto-generated method stub
request = arg0;
}
public String addUser() { System.out.println("进入action的注册功能----------------"); String name = request.getParameter("name"); String pass = request.getParameter("pass"); String username = request.getParameter("username"); String address = request.getParameter("address"); System.out.println("用户名"+name+"密码:"+pass+"昵称"+username+"地址:"+address); User user = new User(); user.setName(name); user.setPass(pass); user.setUsername(username); user.setAddress(address); System.out.println("用户名"+user.getName()+"密码:"+user.getPass()+"昵称"+user.getUsername()+"地址:"+user.getAddress()); boolean b = userService.insertUser(user); System.out.println(b+"执行了action"); if (b==true) { return SUCCESS; } else return INPUT; }
}
前台的jsp页面的访问
<body> <form action="/SSITest/register" method="post"> 用户名:<input type="text" name="name"></br> 密 码:<input type="password" name="pass"></br> 昵 称:<input type="text" name="username"></br> 地 址:<input type="text" name="address"> <input type="submit" value="注册"> <input type="reset" value="取消"> </form> </body>
然后按照MVC的模式设计Demo,然后测试Struts2框架,判断是否搭建成功,整个项目目录如下:
