简单的Spring调用jdbc.porperties配置信息,以mysql为例

1、jdbc.properties配置信息

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/book
jdbc.username=root
jdbc.password=root

2、applicationcontext.xml中调用jdbc.properties配置信息

<?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:aop="http://www.springframework.org/schema/aop"

  xsi:schemaLocation="http://www.springframework.org/schema/beans

    <!-- 加载jdbc.properties配置文件 -->
    <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> 
      <property name="location"> 
          <value>classpath:jdbc.properties</value> 
      </property> 
    </bean>

    <!-- 配置数据源 -->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
      <property name="url" value="${jdbc.url}" /> 
      <property name="driverClassName" value="${jdbc.driverClassName}" /> 
      <property name="username" value="${jdbc.username}" /> 
      <property name="password" value="${jdbc.password}" /> 
    </bean>

</beans>
