1.User.java
package org.myspring.beans;

public class User {
private String username;

private String password;

public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username = username;
}

public void setPassword(String password) {

3.TestMain.java 测试类编写。通过XML文件去读取内容
package org.myspring.beans;

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

public class TestMain {
public static void main(String args[]){
// User user=new User();
// user.setUsername("zwm");
// System.out.println(user.getUsername());
ApplicationContext context=new FileSystemXmlApplicationContext("applicationContext.xml");
User user=(User)context.getBean("user");
System.out.println(user.getUsername());
System.out.println(user.getPassword());  
}
}
