服务对象没有用数据模拟？

Question

Service object not mocked from controller testcase return empty object here is the below code 

    @RunWith(SpringJUnit4ClassRunner.class)
    @SpringApplicationConfiguration(classes = Main.class)
    @WebAppConfiguration
    @ActiveProfiles(ApplicationConstants.DEVELOPMENT_PROFILE)
    public class EmployeeControllerTest {
    @Autowired
    private WebApplicationContext   webAppContext;
    private MockMvc mockMvc;

    @Mock
    EmployeeCompositeService  employeeCompositeService;
    @InjectMocks 
    EmployeeController employeeController;

    String name = "mike";

    @Before
    public void setUp() throws Exception {
        mockMvc = MockMvcBuilders.webAppContextSetup(webAppContext).build();
        MockitoAnnotations.initMocks(this);
    }

    @Test
    public void testGetEmployees() throws Exception {

        Mockito.when(employeeCompositeService.getEmployeesByName(name)).thenReturn(getEmployees());
        String url = URIConstants.ROOT_CONTEXT + URIConstants.EMPLOYEE;
        MvcResult result =
        mockMvc.perform(post(url)
                        .contentType(APPLICATION_JSON_UTF8)
                        .content(convertObjectToJsonBytes(name))
                        .andExpect(status().isOk())
                        .andExpect(content().contentType(APPLICATION_JSON_UTF8))
                        .andExpect(jsonPath("$[0].employeeName").value("Mike"))
                        .andReturn();
        String jsonContent = result.getResponse().getContentAsString();
        LOGGER.debug("jsonContent: {}",jsonContent);

    }

    protected byte[] convertObjectToJsonBytes(Object object) throws IOException {
        ObjectMapper mapper = new ObjectMapper();
        mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
        return mapper.writeValueAsBytes(object);
    }

    private List<Employee> getEmployees(){
    //here is the logic to get List of employees to return. When the mockito call is invoked.
    }

    }

@RestController
@RequestMapping(value = URIConstants.ROOT_CONTEXT)
public EmployeeController{
@Autowired
private EmployeeCompositeService employeeCompositeService;

    @RequestMapping(value=URIConstants.EMPLOYEE, method=RequestMethod.POST, consumes = INPUT_FORMAT, produces = OUTPUT_FORMAT)
    public List<Employees> getEmployees(@RequestBody String name){
        return employeeCompositeService.getEmployeesByName(name); //When invoke this method it calls inner service but not returns the mocked object.

    }
}

我在 EmployeeController 端有一个服务调用，即

employeeCompositeService.getEmployees(String name)

所以我在 EmployeeControllerTestcase 中进行了模拟，即

@Mock EmployeeCompositeService  employeeCompositeService;

当我运行控制器测试用例时，它调用进一步的服务调用和存储库并访问数据库

所以我不想调用内部服务 returns 来自控制器的此调用 employeeCompositeService.getEmployeesByName(name); 的结果。

你能告诉我我在上面的代码中做错了什么提前致谢

EmployeeCompositeService 模拟对象已创建，但未注入到任何地方。这是在测试中初始化一个 class 成员，但由于它没有被注入到控制器中，因此正在使用真实的、面向数据库的实现。要将模拟注入控制器，请在测试中将控制器声明为 class 成员，并使用 org.mockito.InjectMocks 注释对其进行注释。这将从带有 @Mock 注释的测试中获取 class 成员，并将它们注入到实现相同接口的控制器字段中。

下一步是将控制器注入 MockMvc 对象，方法是将其指定为 mockMvc = MockMvcBuilders.standaloneSetup(employeeController).build()。

服务对象没有用数据模拟？
