Spring MVC与Hibernate集成

基本步骤：

1、 配置web.xml

 

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
	
        <!--如果此处没有配置加载spring的配置，那么需要applicationContext.xml放在WEB-INF/下面
 -->
        <context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath*:applicationContext*.xml</param-value>
	</context-param>
	<!-- 设置Spring监听器 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>


	<!-- spring mvc -->

	<servlet>
		<servlet-name>springmvc_annotation</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>springmvc_annotation</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	
</web-app>

 2、配置springmvc_annotation-servlet.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: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-2.5.xsd
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-2.5.xsd">
     
    <!-- ①：对web包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 -->
    <context:component-scan base-package="com.annotation"/>

    <!-- ②：启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>

    <!--  ③：对模型视图名称的解析，即在模型视图名称添加前后缀 
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" 
        p:prefix="/WEB-INF/jsp/" p:suffix=".jsp"/>-->
        
        
        <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
            <property name="prefix" value="/WEB-INF/jsp/"/>
            <property name="suffix" value=".jsp"/>
		</bean>


	
</beans>

    需要注意该配置文件中的 ① 处，该处跟applicationContext.xml中的1处，前者不能包含后者，否则会报错找不到sessionFactory，并且事务会失效。

 

3、配置applicationContext.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"  
  xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"  
  xmlns:p="http://www.springframework.org/schema/p"  
  xsi:schemaLocation="http://www.springframework.org/schema/beans   
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd   
    http://www.springframework.org/schema/context   
    http://www.springframework.org/schema/context/spring-context-3.0.xsd   
    http://www.springframework.org/schema/tx   
    http://www.springframework.org/schema/tx/spring-tx-3.0.xsd   
    http://www.springframework.org/schema/jdbc   
    http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd"
    default-autowire="byName" default-lazy-init="true">  

	

	
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
<property name="namingStrategy">
			<bean class="org.hibernate.cfg.ImprovedNamingStrategy" />
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
				<prop key="hibernate.show_sql">false</prop>
				<prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop>
				<prop key="hibernate.cache.use_query_cache">false</prop>
				<prop key="hibernate.jdbc.batch_size">50</prop>
				<prop key="hibernate.cache.use_second_level_cache">false</prop>			
			</props>
		</property>

		<property name="packagesToScan" value="com.founder"/>
	</bean>

<!-- Support @Transactional tag -->
	<tx:annotation-driven />

	<bean id="transactionManager"
		class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
		
	</bean>
	
	<!--1 扫描dao和service  -->
	<context:component-scan base-package="com.founder">
		<context:include-filter type="regex" expression="com\.founder\.jbpm\.dao\..*"/>
		<context:include-filter type="regex" expression="com\.founder\.jbpm\.service\..*"/>
	</context:component-scan>

	<bean id="dataSource"
		class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="driverClassName" value="com.mysql.jdbc.Driver" />
		<property name="url" value="jdbc:mysql://localhost:3306/xxx" />
		<property name="username" value="xxx" />
		<property name="password" value="xxx" />
	</bean>


</beans>
