1.Junit启动器，配置pox.xml

<!--junit启动器 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId></dependency>

2.编写业务代码

2.1dao

package com.zhy.dao;import org.springframework.stereotype.Repository;@Repository
public class UserDaoImpl implements UserDao{@Overridepublic void addUser() {System.out.println("insert into User .......");}
}

2.2service

package com.zhy.service;import com.zhy.dao.UserDao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;@Service
public class UserServiceImpl implements UserService {@Autowiredprivate UserDao userDao;@Overridepublic void addUser() {userDao.addUser();}
}

2.3编写启动类SpringbootJunitApplication

package com.zhy;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class SpringbootJunitApplication {public static void main(String[] args) {SpringApplication.run(SpringbootJunitApplication.class,args);}
}

2.4整合Junit

package com.zhy.test;import com.zhy.SpringbootJunitApplication;
import com.zhy.service.UserService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;@RunWith(SpringRunner.class)
@SpringBootTest(classes = SpringbootJunitApplication.class)
public class test {@Autowiredprivate UserService userService;@Testpublic  void  testUser(){userService.addUser();}
}
