Spring Comments (eight) ------ common connection pool configuration

First of all, we are ready to Jdbc properties file

jdbc.properties, save the connection information for the database, which will help us in the configuration file

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc\:mysql\://localhost\:3306/mybook
jdbc.username=root
jdbc.password=1234

Registration Jdbc configuration properties file as long as the applicationContext.xml (Spring configuration file)

    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location" value="classpath:jdbc.properties"></property>
    </bean>

or

<context:property-placeholder location="classpath:jdbc.properties"/>

A: Spring frame built connection pool (built jar package may be used)

Of course, it is to use spring-jdbc-4.2.0.RELEASE.jar

(Spring configuration file) configuration in applicationContext.xml:

    <property name="driverClassName" value="${jdbc.driver}"></property>
    <property name="url" value="${jdbc.url}"></property>
    <property name="username" value="${jdbc.username}"></property>
    <property name="password" value="${jdbc.password}"></property>
  </bean>
