Spring Boot整合Junit，@RunWith和@SpringBootTest的使用

1、在pom.xml添加junit启动器

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId>
</dependency>

2、编写测试类

/***  main方法：*		ApplicationContext ac=new *       			ClassPathXmlApplicationContext("classpath:applicationContext.xml");*  junit与spring整合：*      @RunWith(SpringJUnit4ClassRunner.class)：让junit与spring环境进行整合*   	@Contextconfiguartion("classpath:applicationContext.xml")  */
@RunWith(SpringJUnit4ClassRunner.class) 
@SpringBootTest(classes={App.class})//App是项目的启动类名称
public class UserServiceTest {@Autowiredprivate UserServiceImpl userServiceImpl;@Testpublic void testAddUser(){this.userServiceImpl.addUser();}
}
