spring分散案例

PersonServiceBean类：

public class PersonServiceBean {
private String name;
private String sex;
private Integer age;
private Date birth;
//get/set方法

//构造方法

}

bean.xml:

person.properties:

测试：

AppMain:

package cn.csdn.junit;

 

import org.junit.Test;

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

import cn.csdn.service.PersonServiceBean;

public class AppMain {

 @Test
 public void test() {
  ApplicationContext context=new ClassPathXmlApplicationContext("classpath:bean.xml");
  PersonServiceBean personServiceBean=(PersonServiceBean) context.getBean("personServiceBean");
  
  System.out.println(personServiceBean.toString());
  
 }

}
