Junit(手动/自动)加载

 ssm中测试service层数据

 

Junit手动加载配置文件

package com.oukele.bookshop_ssm.service;

import org.junit.After;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class BookServiceTempTest {

    static ClassPathXmlApplicationContext context;

    @BeforeClass
    public static void init(){
        //初始化spring ,让其创建容器,实例化对象
         context = new ClassPathXmlApplicationContext("spring_root.xml");
    }

    @Before
    public void setUp() throws Exception {
    }

    @After
    public void tearDown() throws Exception {
    }

    @Test
    public void listAll() {
        //调用service层里 listAll() 方法 拿到数据
        //  从spring 容器 中 ,取出被spring初始化好的对象
        BookService bean = context.getBean(BookService.class);
        System.out.println(bean.listAll());

    }

    @Test
    public void getBookName() {
    }

    @Test
    public void insert() {
    }

    @Test
    public void update() {
    }

    @Test
    public void insert_log() {
    }
}

Junit自动加载配置文件

package com.oukele.bookshop_ssm.service;


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.SpringRunner;

@RunWith(SpringRunner.class)
@ContextConfiguration(locations = "classpath:spring_root.xml")
public class BookServiceTempTest {

    @Autowired
    private BookServiceTemp bookServiceTemp;

    @Test
    public void listAll() {
        System.out.println(bookServiceTemp.listAll());
    }

    @Test
    public void getBookName() {
    }

    @Test
    public void insert() {
    }

    @Test
    public void update() {
    }

    @Test
    public void insert_log() {
    }
}

 

 如果 使用 自动加载 有出现这个报错(导入 spring-test jar包)
