Struts2+Spring2.5+JPA(Hibernate3)环境搭建，使用注解

也可参考Struts2官方文档

1.新建Web工程

2.在classpath下建立META-INF目录，并在其中创建persistence.xml文件：

< persistence  xmlns ="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation ="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
    version ="1.0" >
     < persistence-unit  name ="oa"  transaction-type ="RESOURCE_LOCAL" >
         < provider > org.hibernate.ejb.HibernatePersistence </ provider >
         < properties >
             < property  name ="hibernate.dialect"  value ="org.hibernate.dialect.MySQL5Dialect"   />
             < property  name ="hibernate.connection.driver_class"  value ="com.mysql.jdbc.Driver"   />
             < property  name ="hibernate.connection.url"  value ="jdbc:mysql://localhost:3306/oa"   />
             < property  name ="hibernate.connection.username"  value ="root"   />
             < property  name ="hibernate.connection.password"  value ="root"   />
             < property  name ="hibernate.show_sql"  value ="true"   />
             < property  name ="hibernate.hbm2ddl.auto"  value ="update" />
         </ properties >
     </ persistence-unit >
</ persistence >

 

3.在WEB-INF目录下建立applicationContext.xml文件：

<? xml version="1.0" encoding="UTF-8" ?>
<!--  Spring上下文配置，包括jpa,dataSource,sessionFactory,Transaction等  -->
< 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:context ="http://www.springframework.org/schema/context"  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/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd" >

     <!--  配置JPA注解支持 -->
     < bean
         class ="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" >
     </ bean >  
    
     <!--  配置实体管理器工厂  -->
     < bean  id ="entityManagerFactory"  class ="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" >
         < property  name ="persistenceUnitName"  value ="oa"   />
     </ bean >
    
     <!--  配置基于注解的声明式事务管理器  -->
     < bean  id ="transactionManager"  class ="org.springframework.orm.jpa.JpaTransactionManager" >
         < property  name ="entityManagerFactory"  ref ="entityManagerFactory"   />
     </ bean >
     < tx:annotation-driven  transaction-manager ="transactionManager"   />
    
     <!--  使用自动扫描方式管理bean -->
     < context:component-scan  base-package ="cn.edu.swu.oa"   />
</ beans >

 

4.在web.xml文件中配置Spring和Struts2：

<? 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 > oa </ 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 >

     <!--  配置Spring应用上下文文件的位置  -->
     < context-param >
         < param-name > contextConfigLocation </ param-name >
         < param-value > /WEB-INF/applicationContext*.xml </ param-value >
     </ context-param >

     <!--  配置Spring监听器  -->
     < listener >
         < listener-class > org.springframework.web.context.ContextLoaderListener </ listener-class >
     </ listener >

     <!--  配置Struts2  -->
     < filter >
         < filter-name > struts2 </ filter-name >
         < filter-class > org.apache.struts2.dispatcher.FilterDispatcher </ filter-class >
     </ filter >
     < filter-mapping >
         < filter-name > struts2 </ filter-name >
         < url-pattern > /* </ url-pattern >
     </ filter-mapping >

     <!--  配置字符编码过滤器  -->
     < filter >
         < filter-name > encoding </ 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 >
     </ filter >
     < filter-mapping >
         < filter-name > encoding </ filter-name >
         < url-pattern > /* </ url-pattern >
     </ filter-mapping >
</ web-app >

 

5.在classpath下建立struts.xml文件，将Struts2委托Spring管理：

<? xml version="1.0" encoding="UTF-8"  ?>
<! DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd" >

< struts >

     <!--  将struts2委托Spring管理  -->
     < constant  name ="struts.objectFactory"  value ="spring" ></ constant >
     < package  name ="test"  extends ="struts-default" >
     </ package >
</ struts >
