spring-jpa（hibernate实现）环境搭建

1，下载hibernate3.3.2，http://sourceforge.net/projects/hibernate/files/hibernate3/3.3.2.GA/hibernate-distribution-3.3.2.GA-dist.zip/download
和hibernate-entitymanager-3.4.0.GA.zip,hibernate-annotations-3.4.0.GA.rar（这里有hibernate注解包和针对jpa实现的包）。

2，解压文件hibernate-distribution-3.3.2.GA-dist.zip到目录hibernate-distribution-3.3.2.GA。

3，提取hibernate实现jpa所需jar包：
--------------------------- hibernate核心包，8个
1）hibernate-distribution-3.3.2.GA/hibernate3.jar
2）hibernate-distribution-3.3.2.GA/lib/bytecode/cglib/cglib-2.2.jar
3）hibernate-distribution-3.3.2.GA/lib/required/*.jar,6个
--------------------------- hibernate注解包，3个
4）hibernate-annotations-3.4.0.GA/hibernate-annotations.jar
5）hibernate-annotations-3.4.0.GA/ejb3-persistence.jar
6）hibernate-annotations-3.4.0.GA/hibernate-commons-annotations.jar
-------------------------- hibernate针对jpa实现的包，3个
7）hibernate-entitymanager-3.4.0.GA/hibernate-entitymanager.jar
8）hibernate-entitymanager-3.4.0.GA/lib/test/log4j.jar
9）hibernate-entitymanager-3.4.0.GA/lib/test/slf4j-log4j12.jar

4,spring的所需jar包

5，spring配置文件src/config/beans.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<context:annotation-config/>

<!-- 集成jpa -->
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
<property name="persistenceUnitName" value="zqm"></property>
</bean>

<bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager">

<bean id="userService" class="com.zqm.jpa.service.impl.UserServiceBean" />

<bean id="hello" class="com.zqm.jpa.web.HelloAction" />

</beans>

6，jpa配置文件src/META-INF/persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
