将外部属性文件的数据配置到bean的配置文件，依赖于context标签下的property-placeholder标签

1、准备properties文件

url=jdbc:mysql://localhost:3306/hibernate_db
username=root
password=1111

2、编写对应实体类

packagecom.yl.bean;

publicclassDataSource{
privateStringurl;
privateStringusername;
privateStringpassword;

publicDataSource(){
}

publicStringgetUrl(){
returnurl;
}

publicvoidsetUrl(Stringurl){
this.url=url;
}

publicStringgetUsername(){
returnusername;
}

publicvoidsetUsername(Stringusername){
this.username=username;
}

publicStringgetPassword(){
returnpassword;
}

publicvoidsetPassword(Stringpassword){
this.password=password;
}

@Override
publicStringtoString(){
return"DataSource{"+
"url='"+url+'\''+
",username='"+username+'\''+
",password='"+password+'\''+
'}';
}
}

3、spring配置文件

4、测试

packagecom.yl;

importcom.yl.bean.DataSource;
importorg.springframework.context.ApplicationContext;
importorg.springframework.context.support.ClassPathXmlApplicationContext;

publicclassMainTest{

publicstaticvoidmain(String[]args){
ApplicationContextapplicationContext=newClassPathXmlApplicationContext("bean1.xml");

DataSourcedataSource=(DataSource)applicationContext.getBean("dataSource");

System.out.println(dataSource);
}
}
