springMVC、hibernate4及spring的整合詳細配置

1、web.xml中配置:

該配置文件主要作用是啓動服務器時加載初始化spring及springMVC。

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" 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">

    <display-name>Spring MVC Form Handling</display-name>

     <!-- Spring監聽器配置,服務器啓動時加載spring並初始化 --> 
     <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>  

    <!-- 指定Spring的配置文件所在目錄。默認配置在WEB-INF目錄下 -->  
    <context-param>  
        <param-name>contextConfigLocation</param-name>  
        <param-value>classpath:spring/spring-servlet.xml</param-value>  
    </context-param> 
    <!-- springMVC的配置 -->
    <servlet>
        <servlet-name>HelloWeb</servlet-name>
        <servlet-class>
           org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <init-param>  
            <param-name>contextConfigLocation</param-name>  
            <param-value>classpath:springmvc/springmvc-servlet.xml</param-value>  
        </init-param>  
    </servlet>

    <servlet-mapping>
        <servlet-name>HelloWeb</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>

</web-app>

2、spring配置文件：spring-servlet.xml
該配置文件主要是讓spring管理bean(控制反轉與依賴注入)。以及讓spring管理hibernate（本示例將hibernate的配置全部由spring管理，不需要hibernate自己的配置文件。spring主要管理hibernate的事務及sessionFactory）。

<?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:context="http://www.springframework.org/schema/context"    
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:task="http://www.springframework.org/schema/task"

    xsi:schemaLocation="http://www.springframework.org/schema/beans

    http://www.springframework.org/schema/tx   
    http://www.springframework.org/schema/tx/spring-tx-3.2.xsd  
    http://www.springframework.org/schema/context  
    http://www.springframework.org/schema/context/spring-context-3.2.xsd  
    http://www.springframework.org/schema/mvc  
    http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
    http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd
    http://www.springframework.org/schema/redis 
    http://www.springframework.org/schema/redis/spring-redis.xsd">  
    <!-- properties文件的引入,引入數據源參數文件 -->
    <!--<context:property-placeholder location="classpath:redis.properties" /> -->
    <!-- bean的掃描組件,指定包下的bean交由spring管理 --> 
   <context:component-scan base-package="cn.test"/>   
    <!-- 數據源配置 -->       
   <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://localhost:3306/cc" />
        <property name="username" value="root"></property>
        <property name="password" value="123456"></property>
    </bean> 
    <!-- hibernate的session工廠配置 --> 
    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" lazy-init="false">
        <!-- 注入datasource，給sessionfactoryBean內setdatasource提供數據源 -->
        <property name="dataSource" ref="dataSource" />        
        <!-- //加載實體類的映射文件位置及名稱 -->
        <property name="mappingLocations" value="classpath:cn/test/hibernate/pojo/*.hbm.xml"></property>
        <!-- hibernate常用配置,不配置使用默認值 -->
        <property name="hibernateProperties">
           <props>
              <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
              <prop key="hibernate.show_sql">true</prop>
           </props>           
        </property>
    </bean>  
    <!-- 設定transactionManager,將事務交由spring管理 -->    
    <bean id="txManager"           class="org.springframework.orm.hibernate4.HibernateTransactionManager">    
        <property name="sessionFactory" ref="sessionFactory" />    
    </bean>    

    <!--啓動spring事務註解功能-->    
    <tx:annotation-driven transaction-manager="txManager"/>  
    <!-- hibernate模板，寫出這部分註釋主要是想說明hibernate4不支持hibernate模板，hibernate3支持 -->
    <!-- <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean> -->              
  </beans>

3、springMVC配置文件：springmvc-servlet.xml

  該配置文件是springMVC所需要的配置文件,該配置使用註解方式配置。

<?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:tx="http://www.springframework.org/schema/tx"  
    xmlns:context="http://www.springframework.org/schema/context"    
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:task="http://www.springframework.org/schema/task"    
    xsi:schemaLocation="http://www.springframework.org/schema/beans   
    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd   
    http://www.springframework.org/schema/tx   
    http://www.springframework.org/schema/tx/spring-tx-3.2.xsd  
    http://www.springframework.org/schema/context  
    http://www.springframework.org/schema/context/spring-context-3.2.xsd  
    http://www.springframework.org/schema/mvc  
    http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
    http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd">  
   <!-- 掃描controller層 -->
   <context:component-scan base-package="cn.ct.hibernate.controller">
      <context:include-filter type="annotation"        expression="org.springframework.stereotype.Controller" />
   </context:component-scan>
   <!-- springMVC的註解驅動,在控制層使用@controller註解即可。使用該方式可以不用手寫映射器和適配器的bean配置。 -->
   <mvc:annotation-driven/>  
   <!-- 配置視圖解析器 --> 
   <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
      <property name="prefix" value="/WEB-INF/jsp/" />
      <property name="suffix" value=".jsp" />
   </bean>
   <!-- 攔截器 -->
   <!--<mvc:interceptors>
      <mvc:interceptor>
         <mvc:mapping path="/testForm"/>
         <bean class="mytest.MyInterceptor"/>
      </mvc:interceptor>
   </mvc:interceptors> -->
</beans>
