如何在使用Spring Boot進行測試時從我的上下文中排除其他@Controller @WebMvcTest

Question

我有多個控制器，我的理解是通過在@WebMvcTest中指定一個控制器，其他控制器不會加載到上下文中。來自docs

控制器 - 指定要測試的控制器。如果應將所有@Controller bean添加到應用程序上下文中，可以留空。

我的第一個控制器

@Controller 
public class MyController { 

    @Autowired 
    private MyService myService; 

    private final Logger logger = Logger.getLogger(this.getClass()); 

    @RequestMapping(value = "/", method = RequestMethod.GET) 
    public @ResponseBody ResponseEntity<String> index() { 
     try { 
      myService.get(); 
      return new ResponseEntity<String>(HttpStatus.OK); 
     } catch (Exception e) { 
      logger.error(e); 
      e.printStackTrace(); 
     } 
     return new ResponseEntity<String>("REQUEST FAILED", HttpStatus.INTERNAL_SERVER_ERROR); 
    } 

} 

我的其他控制器

@Controller 
public class MyOtherController { 

    @Autowired 
    private MyOtherService myOtherService; 

    etc... 
} 

我爲我的控制器

@RunWith(SpringRunner.class) 
@WebMvcTest(controllers = { MyController.class }, secure = false) 
@ActiveProfiles({ "test" }) 
public class MyControllerTest { 

    @Autowired 
    private MockMvc mockMvc; 

    @MockBean 
    MyService myService; 

    @Test 
    public void testBaseReq() throws Exception { 
     Testing dummyData = new Testing(); 
     dummyData.setData("testing"); 
     when(myService.get(anyInt())).thenReturn(dummyData); 

     this.mockMvc.perform(get("/")).andDo(print()).andExpect(status().isOk()); 
    } 
} 

但是當我運行這個測試，它沒有試圖加載測試MyOtherContoller whe的bean MyOtherService n加載上下文。

我以爲指定控制器在WebMvcTest註釋中進行測試會限制它到只有控制器的加載。但是它試圖加載另一個控制器，並且因爲它的bean沒有被模擬，所以它失敗了。

我錯過了什麼或者我的理解不正確？我想我應該只能爲受測試的控制器模擬bean。我也嘗試過一個excludeFilter特別排除其他控制器的軟件包，但沒有更改錯誤。

請確保Application.class測試回升，不含@ComponentScan註解。例如，這是你的包結構

abc-project 
    +--pom.xml 
    +--src 
    +-- main 
     +-- com 
     +-- abc 
      +-- Application.java 
      +-- controller 
      +-- MyController.java 
    +-- test 
     +-- com 
     +-- abc 
      +-- Application.java 
      +-- controller 
      +-- MyControllerTest.java 

的Application.java下測試應類似於此示例中，

@SpringBootApplication 
public class Application { 
    public static void main(String[] args) throws Exception { 
     SpringApplication.run(Application.class, args); 
    } 
} 

Answer 2

my.package.other.myOtherMapper（可能是Mybatis Mapper文件）丟失或未明確初始化。

就我的理解，myOtherService實現類有映射文件沒有正確映射。

您可能必須先映射它們。如果可能，您可以發佈Mapper xml內容。

<context:component-scan base-package="org.example">  
    <context:exclude-filter type="custom" expression="abc.xyz.MyOtherController"/> 
    </context:component-scan>
