UserDaoImpl.java

 1 package com.zhangpn.daoImpl;

 3 import com.zhangpn.dao.UserDao;
 4 
 5 public class UserDaoImpl implements UserDao{
 6     private int i;
 7     private int j;
 8     public int getI() {
 9         return i;

17     public void setJ(int j) {
18         this.j = j;
19     }
20

简单的JavaBean

Test.java

package com.zhangpn.Test;

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

import com.zhangpn.daoImpl.UserDaoImpl;

public class Test {

	public static void main(String[] args) {
		ApplicationContext applicationContext = new ClassPathXmlApplicationContext("beans.xml");
		UserDaoImpl userDaoImpl = (UserDaoImpl)applicationContext.getBean("UserDaoImpl");
		System.out.println(userDaoImpl.getI());
		System.out.println(userDaoImpl.getJ());
	}

}

　　测试结果：
