一、new 一个maven工程

技术分享

会发现报错，这里是因为pom.xml 没有导入servlet依赖的包。导入进去。

pom.xml是控制整个项目的，，是项目对象模型主要包括依赖配置基本配置构建配置项目信息环境设置

导入servlet依赖

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>3.0-alpha-1</version>
<scope>provided</scope>
</dependency>

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>

错误会消失。

创建这些源包

二、配置web.xml文件

1.头文件

<?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">

。

</web-app>

2.配置内容

<display-name>ssh</display-name>

<context-param>
<param-name>contextConfigLocation</param-name> ///这一行是引用配置文件
<param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value> //此行是配置引用文件的路径随后创建此处引用的配置文件，spring.xml spring-hibernate.xml。创建在src/main/resources 文件夹下
</context-param>

处理编码问题

<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>

<-- 配置监听器 -->

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
<description>spring mvc servlet</description>
<servlet-name>rest</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> //DispatcherServlet所有请求的入口
<init-param>
<param-name>contextConfigLocation</param-name> //引用配置文件
<param-value>
classpath:spring-mvc.xml //配置文件的路径spring-mvc.xml spring-mvc 里面配置的controller的信息，DispatcherServlet将对的请求交给controller。或者配置strus框架处理。
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>rest</servlet-name>
<url-pattern>*.htmls</url-pattern> //配置可以被DispatcherServlet处理的后缀名为htmls.
</servlet-mapping>

<session-config>
<session-timeout>30</session-timeout>
</session-config>

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

三、创建第二步中需要的配置文件.xml

技术分享

创建tomcat 跑一下试试

技术分享

发现报错

技术分享

接下来去pom.xml 配置tomcat插件、

<plugins>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.1</version>
<configuration>
<port>9090</port>
<path>/GoTravel</path>
<uriEncoding>UTF-8</uriEncoding>
<server>tomcat7</server>
</configuration>

</plugin>
</plugins>

配置好后，还忘了一件事还没有配置pom.xml的spring响应的包。所有的框架都是通过spring来管理的

配置spring的架包

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>${spring.version}</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring.version}</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>${spring.version}</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring.version}</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>${spring.version}</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>${spring.version}</version>
<scope>provided</scope>
</dependency>

配好后运行发现报错，

这是因为在配置spring包的时候，版本信息通过${ }来取值的，所以还需要配置版本信息，好让${ }可以取到。

<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<spring.version>4.1.4.RELEASE</spring.version>
<hibernate.version>4.3.8.Final</hibernate.version>
<struts2.version>2.3.20</struts2.version>
<jackson.version>2.5.0</jackson.version>
</properties>

运行还是报错！！！！

找不到过滤器对应的类，，这里先把它注释掉暂时用不到，后面在解决，还有把还没有配置的spring.xml spring-xml spring-hibernate.xml 文件都注释掉

运行！！！成功了！！！

四、配置spring.xml 和spring-mvc.xml 实现SS结合。

spring.xml 主要配置的是扫描service层 dao层自动创建对象。以及获取config.propertites配置文件。此文件配置数据的如数据库连接 hibernate设置

<?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">


<context:property-placeholder location="classpath:config.properties"/>

<context:component-scan base-package="com.hwua.service.impl" />

</beans>

配置config.propertites文件。

#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

把前面注释掉的取消掉，，

技术分享

运行不报错了。因为这里的filter 和listener 在spring基础上的，之前没有配置spring.xml 所以报错。

接下来配置spring-mvc 文件

spring-mvc 用来扫描controller ，spring-mvc用来将DispatcherServlet传递过来的请求，交给controller，然后将controller返回的modelandviews 添加前缀和后缀，返回.jsp页面给DispatcherServlet,然后返回给客户端。

1.添加头文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p" 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
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">

。<bean></Bean>

</beans>
2.添加中间配置文件

<context:component-scan base-package="club.itstu.controller" />

添加对应club.itstu.controlle包

<bean id="mappingJacksonHttpMessageConverter"
class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">

<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
//自动装换json格式
<ref bean="mappingJacksonHttpMessageConverter" />
</list>
</property>
</bean>

<list>
<value>text/html;charset=UTF-8</value>
</list>
</property>
</bean>

<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/views" /> //注意添加的前缀的正确
<property name="suffix" value=".jsp" />
</bean>

测试一下写一个测试test

技术分享

package ssh;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/test")
public class TestController {

@RequestMapping("/test")
public String test(){
return "test";

}

}

发现报错了，，应该是之前注释掉的servlet ，，现在给恢复。

运行！！！

到此ss就结合好了，

五、ssh大融合

.配置spring-hibernate.xml

spring-hibernate.xml的配置主要有如下内容：数据源，SessionFactory，事务等的配置

1.添加头文件

<?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: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">

。<beans></beans>

</beans>

2.配置中间的内容

//复制过去即可
<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}" />

<property name="initialSize" value="0" />

<property name="maxActive" value="20" />


<property name="minIdle" value="0" />

<property name="maxWait" value="60000" />
<property name="poolPreparedStatements" value="true" />
<property name="maxPoolPreparedStatementPerConnectionSize"
value="33" />

<property name="validationQuery" value="${validationQuery}" />
<property name="testOnBorrow" value="false" />
<property name="testOnReturn" value="false" />
<property name="testWhileIdle" value="true" />

<property name="timeBetweenEvictionRunsMillis" value="60000" />

<property name="minEvictableIdleTimeMillis" value="25200000" />

<property name="removeAbandoned" value="true" />

<property name="removeAbandonedTimeout" value="1800" />

<property name="logAbandoned" value="true" />

<property name="filters" value="mergeStat" />
</bean>

<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

<property name="dataSource" ref="dataSource" />

<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.show_sql">${hibernate.show_sql}</prop> //这里是hibernate 的配置 ${}取值从congfig.propertites
<prop key="hibernate.format_sql">${hibernate.format_sql}</prop>
<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>

</props>

//这里与实体类entity对应
<property name="mappingResources" >
<list>
<value>mapping/Student.hbm.xml</value> //对应mapping/Student.hbm.xml文件
</list>
</property>

创建对应的entity 和Student.hbm.xml文件

技术分享

<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>

<tx:advice id="transactionAdvice" transaction-manager="transactionManager">

<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" />

<tx:method name="*" />

</tx:attributes>
</tx:advice>

<aop:config>

<aop:pointcut id="transactionPointcut"
expression="execution(* itstu.club.service.impl.*Impl.*(..))" /> /对应相应service层

<aop:advisor pointcut-ref="transactionPointcut"
advice-ref="transactionAdvice" />
</aop:config>

六、配置entity和对应的Student.hbm.xml映射关系及建表！！

1.配置头文件

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

2.配置映射关系 <hibernate-mapping >~~~~~~~</hibernate-mapping>

1.<class name="club.itstu.entity.Student" table="stu"> 、、、、、、 </class> //类名和表名称对应

创建好这个类和对应的表
