Spring2.5+Struts1.3.8+JPA(Hibernate实现)整合之二

该篇主要编写spring和jpa配置文件。

在项目src目录下创建Spring配置文件：applicationContext.xml

文件内容如下：

<?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:aop="http://www.springframework.org/schema/aop"
       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/aop
           http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
	 <context:annotation-config/>
	 <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
	 	<property name="persistenceUnitName" value="zyg_db"></property>
	 </bean>
	 
	 <bean id="txManger" class="org.springframework.orm.jpa.JpaTransactionManager">
		<property name="entityManagerFactory" ref="entityManagerFactory"/>
	</bean>
	<tx:annotation-driven transaction-manager="txManger"/>

</beans>

在src下创建META-INF目录，在该 目录下创建文件persistent.xml

文件内容如下；

<?xml version="1.0" encoding="UTF-8"?>
<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="zyg_db" transaction-type="RESOURCE_LOCAL">
		<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/vote" />
			<property name="hibernate.connection.username" value="root" />
			<property name="hibernate.connection.password" value="zyg" />
			<property name="hibernate.hbm2ddl.auto" value="update"/>
			<property name="hibernate.show_sql" value="true"/>
		</properties>
	</persistence-unit>

</persistence>

注意applicationContext.xml中代码

<property name="persistenceUnitName" value="zyg_db"></property>

中的zyg_db一定要跟persistent.xml中代码

<persistence-unit name="zyg_db" transaction-type="RESOURCE_LOCAL">

中的zyg_db名称完全相同。

至此，编写完成Spring和jpa配置文件，下一篇我们开始编写bean类和DAO层代码。
