Spring整合JUnit spring静态对象属性的注入

package cn.itcast.d_junit4;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import cn.itcast.c_all_annotation.SpringConfiguration;
import cn.itcast.domain.User;

//在测试代码执行前创建spring容器
@RunWith(SpringJUnit4ClassRunner.class)
//指定配置文件位置
//读取xml配置 也可以用数组的locations={classpath:applicationContext.xml}

@ContextConfiguration("classpath:applicationContext.xml")
//读取类配置
//@ContextConfiguration(classes=SpringConfiguration.class)
public class Demo {
    @Autowired
    private User user;
    @Test
    public void fun1(){
        System.out.println(user);
    }
    
}

如果不用@RunWith(SpringJUnit4ClassRunner.class)进行整合,则@Test无法执行applicationContext容器中存储的对象

package cn.itcast.d_junit4;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import cn.itcast.domain.User;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class Demo {
    private static User user;
    public static User getUser() {
        return user;
    }
    @Autowired
    public void setUser(User user) {
        Demo.user = user;
    }
    @Test
    public void fun1(){
        System.out.println(user);
    }
    public static void main(String[] args) {
        System.out.println(Demo.user);
        
    }
}
