Spring对Controller、Service、Dao进行Junit单元测试总结

测试类注解

@RunWith(SpringRunner.class)
@SpringBootTest(classes={DemoApplication.class})

以Controller层的的单元测试为例，idea中直接在方法上右键新建test类

@RunWith(SpringRunner.class)
@SpringBootTest(classes={DemoApplication.class})
class UserControllerTest {

    //注入UserController
    @Autowired
    private UserController userController;

    @Test
    void queryUser() {
        //调用controller层方法
        ArrayList user = (ArrayList) userController.queryUser("1");
        System.out.println(user);
    }
}
