不满足的依赖关系错误：EmployeeController 中缺少 TestService1 Bean

Question

我在运行我的

EmployeeControllerTest

类时遇到以下错误。我被指示不要修改控制器类。有人可以帮我解决这个问题吗？

org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为“...controllers.EmployeeController”的bean时出错：通过字段“testService1”表达的依赖关系不满足：没有可用的“...services.TestService1”类型的合格bean：预计至少有 1 个有资格作为自动装配候选者的 bean。依赖注解：{@org.springframework.beans.factory.annotation.Autowired(required=true)}

我尝试了以下方法：

使用反射设置私有字段， 测试类中的构造函数注入， 创建一个测试配置类来添加必要的 bean， 手动设置依赖项， 我仍然无法解决这个问题。

@ContextConfiguration(classes = {TestConfiguration.class})  
@WebFluxTest(controllers = EmployeeController.class)  
@Profile("local")  
public class EmployeeControllerTest {  
@MockBean  
private TestService1 testService1;  
@MockBean  
private TestService2 testService2;  
private WebTestClient webTestClient;  /* If I use @Autowired for this field, I'm getting an UnsatisfiedDependencyException: Error creating bean due to an unsatisfied dependency expressed through the field 'webTestClient'.*/
@InjectMocks  
private EmployeeController employeeController;  
private JwtAuthenticationToken jwtAuthenticationToken;  
int pageIndex=0;  
int pageSize=10;  

@BeforeEach  
void setup(){  
MockitoAnnotations.openMocks(this);  
jwtAuthenticationToken = mock(JwtAuthenticationToken.class);  
when(jwtAuthenticationToken.getName()).thenReturn("testUser");  
/*If I don't use the code below, I get the error: Cannot invoke "org.springframework.test.web.reactive.server.WebTestClient.post()" because "this.webTestClient" is null.*/
webTestClient = WebTestClient.bindToController(employeeController).webFilter(new SecurityContextServerWebExchangeWebFilter()).build();  
}  
@Test  
void testEmployee(){  
Page<EmployeeDto> mockPage = new PageImpl<>(Collections.emptyList());  
when(testService1.list(eq(jwtAuthenticationToken), eq(pageIndex), eq(pageSize))).thenReturn(Mono.just(mockPage));  
webTestClient.post() .uri("/test/employee/{index}/{size}",pageIndex,pageSize).exchange().expectStatus().isOk().expectBodyList(EmployeeDto.class).hasSize(0);  
}}  

/*Controller Code:I've been instructed not to modify the controller class*/  
@RestController  
@RequestMapping("/test")  
public class EmployeeController {  
@Autowired  //Field injection is not recommended   
private TestService1 testService1;  
@Autowired  //Field injection is not recommended   
private TestService2 testService2;  
@PostMapping("/employee/{index}/{size}")  
public Mono<Page<EmployeeDto>> users(@NonNull JwtAuthenticationToken principal, @PathVariable int index, @PathVariable int size) {  
return testService1.list(principal, index, size);  
}  
}  

Answer 1

测试运行成功，如下。

1. 将

   @ExtendWith(MockitoExtension.class)

   添加到测试类的注释中。
2. 将

   @Autowired

   添加到 WebTestClient 的声明中
3. 删除WebTestClient的初始化分配，因为它是通过上面的注入处理的。
4. 删除字段

   private EmployeeController employeeController;

   。它是通过 WebFluxTest 处理的。

以下测试的完整设置，省略测试用例：

@ContextConfiguration(classes = {TestConfiguration.class})
@WebFluxTest(controllers = EmployeeController.class)
@ExtendWith(MockitoExtension.class)
public class EmployeeControllerTest {

    @MockBean
    private TestService1 testService1;

    @MockBean
    private TestService2 testService2;

    @Autowired
    private WebTestClient webTestClient;

    private JwtAuthenticationToken jwtAuthenticationToken;

    int pageIndex=0;
    int pageSize=10;

    @BeforeEach
    void setup(){
        MockitoAnnotations.openMocks(this);
        jwtAuthenticationToken = mock(JwtAuthenticationToken.class);
        when(jwtAuthenticationToken.getName()).thenReturn("testUser");

        //removed this code:
//        webTestClient = WebTestClient.bindToController(employeeController)
//                .webFilter(new SecurityContextServerWebExchangeWebFilter()).build();
    }

    //your test methods follow...
}
