Question

我有一个UsernameController，我正在尝试为其建立单元测试。我需要模拟一个User对象，而我尝试使用@WithMockUser

Controller:
@RestController
@RequestMapping(value = "/username")
public class UsernameController {

/* Simply return the username */
@RequestMapping(method = RequestMethod.GET)
public CommonWebResponse<Map<String, Object>> read(@CurrentlyLoggedUser User currentUser) {
    Map<String, Object> result = new HashMap<>();

    result.put("username", currentUser.getUsername());
    result.put(
            "roles",
            currentUser
                    .getAuthorities()
                    .stream()
                    .map(GrantedAuthority::getAuthority)
                    .collect(Collectors.toList()));
    return new SuccessWebResponse<>(result);
}

}

CurrentlyLogged用户界面：

@Target({ElementType.PARAMETER, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@AuthenticationPrincipal
public @interface CurrentlyLoggedUser {}

单元测试：

@RunWith(SpringRunner.class)
@SpringBootTest
public class UsernameControllerTest {

    private MockMvc mvc;

    private UsernameController controller;

    @Before
    public void setUp(){
        controller = new UsernameController();
        MockitoAnnotations.initMocks(this);
        mvc = MockMvcBuilders.standaloneSetup(controller).build();
    }

    @Test
    @WithMockUser(username = "admin", roles = {"USER", "ADMIN"})
    public void testGetUsername() throws Exception{
        MockHttpServletResponse response = mvc.perform(get("/username")
                .contentType(MediaType.APPLICATION_JSON)
        ).andReturn().getResponse();

        Assert.assertNotNull(response);
    }
}

但是，当我运行此测试时，出现以下异常错误：

No primary or default constructor found for class org.springframework.security.core.userdetails.User

如何正确模拟spring User对象，以便此控制器方法将其接受？

Spring无法模拟@CurrentlyLoggedUser
