在pring-data-jpa中使用druid进行数据库连接的配置

1.application.xml配置

<?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"

    xmlns:task="http://www.springframework.org/schema/task" xmlns:jpa="http://www.springframework.org/schema/data/jpa"

          http://www.springframework.org/schema/task    
          http://www.springframework.org/schema/task/spring-task-4.3.xsd
          http://www.springframework.org/schema/data/jpa  
          http://www.springframework.org/schema/data/jpa/spring-jpa.xsd"
    default-lazy-init="false">
    <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&amp;characterEncoding=utf-8&amp;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 -->
        <property name="maxWait" value="60000" />
        <!-- 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" />
        <!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
        <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"
        class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="jpaVendorAdapter">
            <bean
                class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
                <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。
