Question

我正在尝试使用Spring MockMvc测试带有几个HTTP谓词的控制器。目前GET和DELETE按预期工作，但PUT和PATCH未返回201，应该是。

PATCH控制器设置如下：

@CustomRequestMapping(method = PATCH, value = "/{api-root}")
public ResponseEntity patch(@PathVariable(value = "api-root") String id, @RequestBody ApiRoot apiRoot) {
     return apiRootService.softUpdate(id, apiRoot);
}

@CustomRequestMapping...注释只是将consumes和produces设置为特定的内容类型。

上面引用的softUpdate()方法执行以下操作：

public ResponseEntity softUpdate(String id, ApiRoot apiRoot) {
    if (apiRoot.getId() == null) {
        apiRoot.setId(id);
    }

    ApiRootDocument updated = softUpdate(apiRoot);
    return ResponseEntity
            .created(EscapeUtil.buildUrl(applicationProperties.getHostname(), applicationProperties.getPort(), id))
            .body(updated);
}

这是在MockMvc单元测试之外的工作和测试。它正确地将201 Created返回给Postman，正文是由PATCH创建的新JSON对象。

我的测试设置为：

public void testPatchApiRootEndpoint() throws Exception {
    String testTitle = "New Test Title";

    // Mock the service call for softUpdate() to return 'created' in the same way that the method does
    when(apiRootService.softUpdate(TestData.apiRoot1.getId(), TestData.apiRoot1.withTitle(testTitle)))
            .thenReturn(ResponseEntity
                .created(URI.create(EscapeUtil.buildUrlString("localhost", "8001", TestData.apiRoot1.getId())))
                .body((ApiRootDocument) TestData.apiRoot1.withTitle(testTitle)));

    // Perform a patch update using a new title provided as key-value
    JsonObject titleJson = new JsonObject();
    titleJson.addProperty("title", testTitle);
    mockMvc.perform(patch("/{api-root}", TestData.apiRoot1.getId())
                .contentType(Constants.TAXII2_CONTENT_TYPE)
                .content(titleJson.toString()))
            .andExpect(status().isCreated());
}

这导致返回200，而不是201。我真的很困惑，很难研究。大多数类似问题是在他们期望2XX时找到4XX响应代码，而解决方案通常与请求的设置有关。

我能找到的唯一有趣的日志是：

看起来你的模拟电话不起作用。您可以轻松检查是否将值替换为any（）：

when(apiRootService.softUpdate(Mockito.any(), Mockito.any())
.thenReturn(ResponseEntity
                .created(URI.create(EscapeUtil.buildUrlString("localhost", "8001", TestData.apiRoot1.getId())))
                .body((ApiRootDocument) TestData.apiRoot1.withTitle(testTitle)));

我刚检查过你是否使用了来自控制器的错误模拟返回200状态，但如果模拟是正确的，我得到201.

请确保您在模拟中设置的响应以及在mvc.perform中期望的响应，因为您可能返回200并期望返回201。

response.setResult(serviceOrder);
response.setStatus(Response.RESPONSE_CREATED);

when(serviceHandler.processOrder(Mockito.any(ServiceOrderCreate.class))).thenReturn(response);


try {
    mockMvc.perform(MockMvcRequestBuilders.post("/serviceOrder").contentType(MediaType.APPLICATION_JSON)
            .content(asJsonString(orderInfo)).accept(MediaType.APPLICATION_JSON))
        .andDo(print())
        .andExpect(status().isAccepted());

Spring MockMvc返回200而不是201.如何调试？
