嗨，我正在使用 Spring rest Template 来访问 POST API，它工作得非常好。

问题是当我将它与 MockRestServiceServer 一起使用时。

我创建了一个 MockRestServiceServer 实例：

mockServer = MockRestServiceServer.createServer(restTemplate);

并添加了预期的请求 URL 和响应，即：

mockServer.expect(requestTo(URL)).andExpect(method(HttpMethod.POST))
    .andRespond(withSuccess(Response,MediaType.APPLICATION_JSON));

当我尝试使用 JSON 正文点击特定的 POST URL 时

{"AppName":{"Value":"Google"}}

我收到错误

org.springframework.http.converter.HttpMessageNotReadableException: 
Could not read JSON: Unexpected character ('A' (code 65)): was expecting double-quote 
to start field name  at 
[Source: java.io.ByteArrayInputStream@5473b9e; line: 1, column: 3];

谁能帮助我我在这里缺少什么？
