spring 引入外部配置文件

标签：spring

beans-properties.xml

<?xml version="1.0" encoding="UTF-8"?>

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

</beans>

外部文件为:db.properties

jdbc.user=root
jdbc.password=1230
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.jdbcUrl=jdbc:mysql:///test

测试类：

package com.spring.properties;

import java.sql.SQLException;

import javax.sql.DataSource;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class main {
    public static void main(String[] args) throws Exception {

    ApplicationContext ctx = new ClassPathXmlApplicationContext("beans-properties.xml");
   DataSource source = (DataSource) ctx.getBean("dataS");
   System.out.println(source.getConnection());
}
}
