我正在为我的@RequestMapping方法的自定义错误场景设计一个 POJO 。

Spring 默认抛出 a HttpMessageNotReadableExceptionif a POSTis made without any body 并很好地返回错误响应，如下所示：

{
    "timestamp": "2017-07-28T18:54:11.867+0000",
    "status": 400,
    "error": "Bad Request",
    "exception": "org.springframework.http.converter.HttpMessageNotReadableException",
    "message": "Required request body is missing: public org.springframework.http.ResponseEntity<some.package.name.SomeResponseClass> some.package.name.SomeControllerClass.someRequestMappingMethod(java.util.Map<java.lang.String, java.lang.String>, some.package.name.SomeRequestClass)",
    "path": "/somepath/"
}

类似地，如果对任何注释的字段的验证@Valid失败，它会抛出MethodArgumentNotValidException并返回错误响应，如下所示：

{
    "timestamp": "2017-07-28T17:23:53.102+0000",
    "status": 400,
    "error": "Bad Request",
    "exception": "org.springframework.web.bind.MethodArgumentNotValidException",
    "errors": [
        {
            "codes": [
                "NotNull.incident.someField",
                "NotNull.someField",
                "NotNull.java.lang.String",
                "NotNull"
            ],
            "arguments": [
                {
                    "codes": [
                        "someObject.someField",
                        "someField"
                    ],
                    "arguments": null,
                    "defaultMessage": "someField",
                    "code": …

我正在尝试测试应该使用自定义错误属性的Spring Boot RestController.

    @Bean
public ErrorAttributes errorAttributes() {
    return new DefaultErrorAttributes() {

        @Override
        public Map<String, Object> getErrorAttributes(
                RequestAttributes requestAttributes,
                boolean includeStackTrace) {
            Map<String, Object> errorAttributes = super.getErrorAttributes(requestAttributes, includeStackTrace);
            Throwable error = getError(requestAttributes);
            return errorAttributes;
        }

    };
}

但是当我尝试使用简单测试来测试自定义错误属性时,不会考虑这些属性.下面的测试实际上会触发一个请求,除了使用自定义属性.但无论我做什么,代码似乎都没有被考虑在内.

class TestSpec extends Specification {

    MockMvc mockMvc

    def setup() {
        mockMvc = MockMvcBuilders.standaloneSetup(new HelloWorldController()).build()
    }

    def "Test simple action"() {
        when:
        def response = mockMvc.perform(post("/hello")
                .contentType(MediaType.APPLICATION_JSON)
                .content('{"sayHelloTo": ""}')
        )

        then:
        response.andExpect(status().isOk())
    }
}

关于我如何测试自定义属性的任何线索？

鉴于以下有效负载:

data public class CandidateDetailDTO(val id: String,
                                     val stageName: String,
                                     val artists: Iterable<ArtistDTO>,
                                     val instruments: Iterable<InstrumentDTO>,
                                     val genres: Iterable<GenreDTO>,
                                     val discoverable: Boolean,
                                     val gender: Gender,
                                     val involvement: Involvement,
                                     val biography: String,
                                     var photoURLs: List<URL>,
                                     var birthday: Date? = null,
                                     var customGenre: String? = null)

..如图所示,某些字段允许为空,其他字段不允许.

使用Spring Boot调用请求时,如果缺少预期字段,则返回400 - Bad Request.这是不太令人期待的,我期望相关的控制器建议适用:

@ControllerAdvice
public class SomeExceptionHandler : ResponseEntityExceptionHandler()
{
    @ExceptionHandler(Throwable::class)
    @ResponseBody
    public fun onException(ex: Throwable): ResponseEntity<ErrorResponse>
    {
        val responseCode = ex.responseCode()
        val errorResponse = ErrorResponse(response = ResponseHeader(responseCode, ex.message))
        return ResponseEntity(errorResponse, responseCode.httpStatus());
    } …
