使用 LocalDateType 的 @RequestParam 对 RestController 进行单元测试

[英]Unit test of RestController with @RequestParam of LocalDateType

问题描述

I need to write a unit test from RestController , which just checks status.Ok.我需要从RestController编写一个单元测试，它只检查 status.Ok。 My controller:我的 controller：

@RestController
public class OrderController {

    @Autowired
    ServiceOrder serviceOrder;

    @PreAuthorize("hasRole('ROLE_ADMIN')")
    @RequestMapping(value = "/orders/completed/period", method= RequestMethod.POST, produces={"application/json"})
    public long showCompletedOrdersInPer(@RequestParam (value = "start") @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) LocalDate startDate,
                                         @RequestParam (value = "end") @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) LocalDate endDate) {
        return serviceOrder.completedOrdersInPeriod(startDate, endDate);
    }
}

This is my Test:这是我的测试：

@ExtendWith(SpringExtension.class)
@ContextConfiguration(classes = ControllersTestConfig.class)
@WebAppConfiguration
public class OrderControllerTest {

    @Autowired
    private WebApplicationContext webApplicationContext;

    @Autowired
    OrderController orderController;

    @Autowired
    ServiceOrder serviceOrder;

    private MockMvc mockMvc;
    @BeforeEach
    public void setup() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.webApplicationContext).build();
    }
    // Test from method OrderController.showCompletedOrdersInPer
    // Description: we should get response.status OK
    @Test
    public void showCompletedOrdersInPerTest() throws Exception {
        Mockito.when(serviceOrder.completedOrdersInPeriod(Mockito.any(), Mockito.any())).thenReturn(1L);
        mockMvc.perform(MockMvcRequestBuilders.post("/orders/completed/period?start=2020-01-01&end=2022-01-01")).andExpect(MockMvcResultMatchers.status().isOk());
    }

I have also the next config:我还有下一个配置：

public class ControllersTestConfig {

    @Bean
    public ServiceOrder serviceOrder() {
        return Mockito.mock(ServiceOrder.class);
    }

    @Bean
    public OrderController orderController(){
        return new OrderController();
    }
}

Well, when I run the test, it failed with the message: Status expected:<200> but was:<500> .好吧，当我运行测试时，它失败了并显示消息： Status expected:<200> but was:<500> 。 I think it s about auto parsing to LocalDate in RestController` because such a test without LocalDate variables in @RequestParam was successful.我认为这s about auto parsing to LocalDate in因为在 @RequestParam 中没有 LocalDate 变量的这种测试是成功的。 How can I specify the LocalDate type in my test?如何在我的测试中指定 LocalDate 类型？ Update: stackTrace更新：堆栈跟踪

when i debugging, i found next exception: org.springframework.web.method.annotation.MethodArgumentConversionNotSupportedException: Failed to convert value of type 'java.lang.String' to required type 'java.time.LocalDate';当我调试时，我发现下一个异常： org.springframework.web.method.annotation.MethodArgumentConversionNotSupportedException: Failed to convert value of type 'java.lang.String' to required type 'java.time.LocalDate'; nested exception is java.lang.IllegalStateException: Cannot convert value of type 'java.lang.String' to required type 'java.time.LocalDate': no matching editors or conversion strategy found嵌套异常是 java.lang.IllegalStateException：无法将类型“java.lang.String”的值转换为所需类型“java.time.LocalDate”：找不到匹配的编辑器或转换策略

Well, i had to change types of input variables in my controller to String, and insight controller i had parsing String to LocalDate.好吧，我不得不将我的 controller 中的输入变量类型更改为字符串，并且洞察力 controller 我将字符串解析为 LocalDate。 I know, that not best choice, but it works我知道，这不是最好的选择，但它确实有效
