SpringJUnit4加载类目录下(src)和WEFINF目录下的配置文件二获取注入的bean的二种方式

package com.my.test;

import javax.annotation.Resource;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.wql.vo.User;

/**

 * 加载文件放在类目录下
 * @author Lenovo
 *
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class MyTest {
    @Resource
    private User user3;//用@Resource关键字自动注入获取bean。注意：引用名是在spring容器中的注入bean的id，不可瞎写！
    
    @Test
    public void test1(){//用FileSystemXmlApplicationContext获取bean
        ApplicationContext ac = new FileSystemXmlApplicationContext("classpath:applicationContext.xml");
        System.out.println(ac);//org.springframework.context.support.FileSystemXmlApplicationContext@52c603e7: startup date [Tue Feb 02 09:38:46 CST 2016]; root of context hierarchy
    }
    @Test
    public void test2(){//用ClassPathXmlApplicationContext获取bean
        ApplicationContext act=new ClassPathXmlApplicationContext("applicationContext.xml");
        
        User user=(User)act.getBean("user");
        System.out.println(user);
    }
    @Test
    public void test3(){
        System.out.println(user3);
    }

}
