1.application.xml配置

<context:property-placeholder location="classpath:config/*.properties" />
<!--开启这个配置,spring识别@Scheduled注解 -->
<task:annotation-driven />
<!-- -->
<context:component-scan base-package="com.ninelephas.terrier" />
<!-- 激活自动代理功能 -->
<aop:aspectj-autoproxy proxy-target-class="true" />
<!-- -->

<!-- jdbc jpa连接 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<!-- 基本属性 url、user、password -->
<property name="url"
value="jdbc:mysql://192.168.1.111:3306/terrier?useUnicode=true&characterEncoding=utf-8&useSSL=false" />
<property name="username" value="whale" />
<property name="password" value="whale" />
<!-- 配置初始化大小、最小、最大 -->
<property name="initialSize" value="1" />
<property name="minIdle" value="1" />
<property name="maxActive" value="20" />
<!-- 配置获取连接等待超时的时间 -->

<!-- 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒 -->
<property name="timeBetweenEvictionRunsMillis" value="60000" />

<property name="minEvictableIdleTimeMillis" value="300000" />
<property name="validationQuery" value="SELECT 'x'" />
<property name="testWhileIdle" value="true" />
<property name="testOnBorrow" value="false" />
<property name="testOnReturn" value="false" />
<!-- 打开PSCache,并且指定每个连接上PSCache的大小 -->
<property name="poolPreparedStatements" value="true" />
<property name="maxPoolPreparedStatementPerConnectionSize"
value="20" />
<!-- 配置监控统计拦截的filters -->
<property name="filters" value="stat" />
</bean>

<!-- JPA实体管理器工厂 -->
<bean id="entityManagerFactory"

<property name="jpaVendorAdapter">

<property name="generateDdl" value="true" />
<property name="database" value="MYSQL" />
</bean>
</property>
<property name="persistenceUnitName" value="Terrier_PU" />
<property name="dataSource" ref="dataSource"></property>
</bean>

<!-- 配置事务管理器 -->
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

<!-- 启用 annotation事务 -->
<tx:annotation-driven transaction-manager="transactionManager" />

<!-- 配置Spring Data JPA扫描目录 -->
<jpa:repositories base-package="com.ninelephas.terrier" />
<!-- end -->

<import resource="classpath:META-INF/spring-config-cache.xml" />
</beans>


注意: 这里使用了

<property name="dataSource" ref="dataSource"></property>


指定了 druid中的dataSource配置。

2.配置persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1"
xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"> <persistence-unit name="Terrier_PU"
transaction-type="RESOURCE_LOCAL">
<class>com.ninelephas.terrier.entity.AuthList</class>

</persistence-unit>
</persistence>


这里不配置jdbc连接信息了。
