struts1+spring+JPA环境搭建及配置

Spring2.5+JPA+Struts1.3整合开发  这里JPA的实现采用hibernate，需要使用到下面的jar文件 Hiberante核心包(8个文件) hibernate-distribution-3.3.1.GA --------------------------------------------- hibernate3.jar lib/bytecode/cglib/hibernate-cglib-repack-2.1_3.jar lib/required/*.jar Hiberante注解包(3个文件)：hibernate-annotations-3.4.0.GA ------------------------------------------------------------------------------------ hibernate-annotations.jar lib/ejb3-persistence.jar、hibernate-commons-annotations.jar Hibernate针对JPA的实现包(3个文件)：hibernate-entitymanager-3.4.0.GA ------------------------------------------------------------------------------------------------------ hibernate-entitymanager.jar lib/test/log4j.jar、slf4j-log4j12.jar  Spring2.5与struts1.3需要的jar Spring安装包下的 dist/spring.jar dist/modules/spring-webmvc-struts.jar lib/jakarta-commons/commons-logging.jar、commons-dbcp.jar、commons-pool.jar lib/aspectj/aspectjweaver.jar、aspectjrt.jar lib/cglib/cglib-nodep-2.1_3.jar lib/j2ee/common-annotations.jar lib/log4j/log4j-1.2.15.jar Struts 下载struts-1.3.8-lib.zip，需要使用到解压目录下的所有jar，建议把jstl-1.0.2.jar和standard-1.0.2.jar更换为1.1版本。Spring中已经存在一个antlr-2.7.6.jar，所以把struts中的antlr-2.7.2.jar删除，避免jar冲突。  Spring2.5+JPA+Struts1.3整合开发 JPA规范要求在类路径的META-INF目录下放置persistence.xml，文件的名称是固定的，配置模版如下： <?xml version="1.0"?> <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="itcast" transaction-type="RESOURCE_LOCAL">       <properties>          <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>          <property name="hibernate.connection.driver_class" value="org.gjt.mm.mysql.Driver"/>          <property name="hibernate.connection.username" value="root"/>          <property name="hibernate.connection.password" value="123456"/>          <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/itcast?useUnicode=true&amp;characterEncoding=UTF-8"/>          <property name="hibernate.max_fetch_depth" value="3"/>          <property name="hibernate.hbm2ddl.auto" value="update"/>       </properties>   </persistence-unit> </persistence>  在spring中配置EntityManagerFactory <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">       <property name="persistenceUnitName" value="itcast"/>   </bean>   <bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager">   <property name="entityManagerFactory" ref="entityManagerFactory"/>   </bean>  <tx:annotation-driven transaction-manager="txManager"/>  使用spring解决JPA因EntityManager关闭导致的延迟加载例外问题。  <filter>         <filter-name>Spring OpenEntityManagerInViewFilter</filter-name>         <filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class>         <init-param>    <!-- 指定org.springframework.orm.jpa.LocalEntityManagerFactoryBean在spring配置文件中的名称,默认值为entityManagerFactory.如果LocalEntityManagerFactoryBean在spring中的名称不是entityManagerFactory,该参数一定要指定,否则会出现找不到entityManagerFactory的例外 -->             <param-name>entityManagerFactoryBeanName</param-name>             <param-value>entityManagerFactory</param-value>       </init-param> </filter> beans.xml<?xml version="1.0" encoding="UTF-8"?>

    <!--  使用数据源和指定persistence.xml位置的方式创建entityManagerFactory,如果使用的不是hibernate JPA实现,
    需要在tomcat作一些特殊配置.具体参考手册
    注意:使用该方式需要把persistence.xml中的hibernate.connection.driver_class,hibernate.connection.username,hibernate.connection.password,hibernate.connection.url配置删除
