java.lang.AssertionError: Status expected:<200> but was:<400> for Spring Boot Rest Controller Patch request

Question

下面是我的控制器 (SalesOrderController.Java) 和 JUnit 测试 (SalesOrderControllerTest.Java)

@RestController

公共类 SalesOrderController 扩展 BaseController {

/** The Constant LOGGER. */
private static final Logger LOGGER = LoggerFactory.getLogger(SalesOrderController.class);

/** The sales order service. */
@Autowired
private ISalesOrderService salesOrderService;

@CrossOrigin
@RequestMapping(value = "/issuers/{issuerId}/reassign-sales-orders", method = RequestMethod.PATCH, produces = MediaType.APPLICATION_JSON_VALUE, consumes = MediaType.APPLICATION_JSON_VALUE)
public BaseResponse reassignSalesOrder(@PathVariable("issuerId") final Long pIssuerId,
        @RequestBody @Valid final ReassignSalesOrderRequest pReassignSalesOrderRequest) {
    LOGGER.info("Reassigning sales orders of issuer:" + pIssuerId);
    return salesOrderService.reassignSalesOrder(pIssuerId, pReassignSalesOrderRequest);
}

}

下面是我上面控制器的Junit

@RunWith(MockitoJUnitRunner.class)

公共类 SalesOrderControllerTest 扩展 AbstractBaseControllerTest {

/** The sales order service. */
@Mock
private ISalesOrderService salesOrderService;

/** The sales order controller. */
@InjectMocks
private SalesOrderController salesOrderController;

@Before
public void setUp() throws Exception {
    mockMvc = MockMvcBuilders.standaloneSetup(salesOrderController).build();
}

@Test
public void testReassignSalesOrder() throws Exception {
    ReassignSalesOrderRequest lSalesOrderUpdateRequest = new ReassignSalesOrderRequest();
    lSalesOrderUpdateRequest.setRedirectOption("Satellite");
    lSalesOrderUpdateRequest.setSatelliteId(200L);
    lSalesOrderUpdateRequest.setSalesOrderIds(Collections.singletonList(1L));
    when(salesOrderService.reassignSalesOrder(100L, lSalesOrderUpdateRequest)).thenReturn(new BaseResponse());
    ObjectMapper mapper = new ObjectMapper();
    mockMvc.perform(patch("/api/issuers/100/reassign-sales-orders")
            .contentType(MediaType.APPLICATION_JSON_UTF8).accept(MediaType.APPLICATION_JSON_UTF8)
            .content(mapper.writeValueAsString(lSalesOrderUpdateRequest)))
            .andExpect(status().isOk());
    verify(salesOrderService).reassignSalesOrder(100L, lSalesOrderUpdateRequest);
}

}

那么为什么我收到这个错误我的代码有什么问题？

Answer 1

有两种简单的方法可以找出答案。

• 调试您的测试代码并查看响应正文，而不仅仅是状态代码。甚至也可以在身体上断言。
• 将您的日志级别设置为调试，您的 Spring 应用程序肯定也会显示错误客户端请求的错误。

Answer 2

我遇到了同样的问题。 确保您的类 ReassignSalesOrderRequest 具有所有 setter、getter 和构造函数（主要是无参数构造函数）。
