SSH（SpringMVC）整合

一、导入jar包，包括hibernate所需核心包、mysql连接包、c3p0连接池包、Spring所需包，commonslogging包、SpringMVC所需包,AOP注解所需jar包

 

二、配置文件

   1.配置web.xml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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>mySpringMVCSH</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
  
  <!-- 供Spring读取的配置文件的设置 -->
  <context-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>classpath:application*.xml</param-value>
  </context-param>
  
  <!-- 配置监听器 进行配置文件的读取,IOC中注册bean -->
  <listener>
  	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  <servlet>
  	<servlet-name>spring</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  	<!-- 指定SpringMVC配置文件的文件名 -->
  	<init-param>
  		<param-name>contextConfigLocation</param-name>
  		<param-value>classpath:spring-servlet.xml</param-value>
  	</init-param>
  	<load-on-startup>1</load-on-startup>
  </servlet>
  
  <servlet-mapping>
  	<servlet-name>spring</servlet-name>
  	<url-pattern>/</url-pattern>
  </servlet-mapping>
  
</web-app>

   2.配置spring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:aop="http://www.springframework.org/schema/aop"
	xmlns:jdbc="http://www.springframework.org/schema/jdbc"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-4.3.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
		http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">

	<!-- 扫描注解 除去Controller注解 -->
	<context:component-scan base-package="com.lanou3g">
		<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
	</context:component-scan>
	
	<!-- 读取配置文件 -->
	<context:property-placeholder location="classpath:db.properties"/>

	<!-- 配置dataSource -->
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
		<property name="driverClass" value="${jdbc.driverClass}"></property>
		<property name="jdbcUrl" value="${jdbc.url}"></property>
		<property name="user" value="${jdbc.user}"></property>
		<property name="password" value="${jdbc.password}"></property>
	</bean>
	
	<!-- 配置sessionFactory -->
	<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource"></property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
				<prop key="hibernate.show_sql">true</prop>
				<prop key="hibernate.format_sql">true</prop>
				<prop key="hibernate.hbm2dll.auto">update</prop>
			</props>
		</property>
		<property name="mappingLocations" value="classpath:com/lanou3g/entity/*.hbm.xml"></property>
	</bean>
	
	<!-- 配置事务 -->
	<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>
	
	<!-- 开启事务注解 -->
	<tx:annotation-driven transaction-manager="transactionManager"/>
	<!-- 开启AOP注解 -->
	<aop:aspectj-autoproxy></aop:aspectj-autoproxy>

</beans>

3.配置SpringMVC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:mvc="http://www.springframework.org/schema/mvc"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">

	<!-- 扫描注解 只扫描Controller注解 -->
	<context:component-scan base-package="com.lanou3g.controller"></context:component-scan>

	<!-- 配置视图解析器 -->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<!-- 视图的路径 -->
		<property name="prefix" value="/resource/views/"></property>
		<!-- 视图的格式 -->
		<property name="suffix" value=".jsp"></property>
	</bean>
	
	<!-- 配置静态资源处理 -->
	<mvc:resources location="/resource/" mapping="/resource/**"></mvc:resources>
	
	<!-- 启动注解 -->
	<mvc:annotation-driven />
</beans>

三、HelloWorld

@Controller
public class UserController {
	
	@RequestMapping(value="/hi")
	public String hello() {
		System.out.println("HelloWorld");
		return "hello";
	}
	
}
