这是我的密码。我不明白为什么它不起作用。问题在于线路输入测试：
when(applicationUserRepository.findApplicationUserByUsername("testUser"))
.thenReturn(userToReturnFromRepository);似乎什么都没做。当函数findapplicationuserbyusername应该返回usertoreturnfromrepository的可选值时，它返回一个空的可选值。
控制器：
@RestController
@RequestMapping("api/v1/exercises")
public class ExerciseController {
@Autowired
ExerciseService exerciseService;
@GetMapping
public List<Exercise> getExercises() {
List<Exercise> exercises = exerciseService.getAllExercises();
return exercises;
}
}服务：
@Service("exerciseService")
public class ExerciseService {
@Autowired
ExerciseRepository exerciseRepository;
@Autowired
ApplicationUserRepository applicationUserRepository;
@Transactional
public List<Exercise> getAllExercises() {
Principal principal = SecurityContextHolder.getContext().getAuthentication();
Optional<ApplicationUser> applicationUser = applicationUserRepository.findApplicationUserByUsername(principal.getName());
List<Exercise> exercises = new ArrayList<>();
if(applicationUser.isPresent()){
exercises = applicationUser.get().getExercises();
}
return exercises;
}
}测试：
@SpringBootTest
@AutoConfigureMockMvc(addFilters = false)
public class ExerciseControllerTest {
private final MockMvc mockMvc;
private final ObjectMapper objectMapper;
@Mock
ApplicationUserRepository applicationUserRepository;
@Autowired
public ExerciseControllerTest(MockMvc mockMvc,
ApplicationUserRepository applicationUserRepository, ObjectMapper objectMapper) {
this.mockMvc = mockMvc;
this.applicationUserRepository = applicationUserRepository;
this.objectMapper = objectMapper;
}
@BeforeEach
public void initMocks() {
MockitoAnnotations.openMocks(this);
}
@Test
@WithMockUser(username = "testUser")
public void testGetExercises() throws Exception {
Exercise ex = new Exercise();
ex.setData("test");
ApplicationUser user = new ApplicationUser();
Exercise[] exercises = {ex};
List<Exercise> list = new ArrayList<Exercise>(Arrays.asList(exercises));
user.setExercises(list);
Optional<ApplicationUser> userToReturnFromRepository = Optional.of(user);
when(applicationUserRepository.findApplicationUserByUsername("testUser"))
.thenReturn(userToReturnFromRepository);
mockMvc.perform(get("/api/v1/exercises")).andExpect(status().isOk()).andExpect(jsonPath("$", hasSize(1)));
}
}

在你的测试中有两个矛盾的事情发生：
您正在使用mockito通过反射初始化一个mock实现
applicationuserrepository通过构造函数被spring注入到测试类中。
最终的结果是：
spring将applicationuserrepository注入构造函数参数
applicationuserrepository字段在构造函数中设置为spring注入版本
mockito初始化一个新的applicationuserrepository mock
mockito用mock替换applicationuserrespository字段（即，告别mvc安装程序正在使用的springbean的句柄！）
我能想到的最简单的解决方法是使用@mockbean而不是@mock结合构造函数注入@mockbean将指示spring为您创建模拟示例，使用它，并在测试中提供给您。
