意外的字符（'A'（代码65））：期望双引号来启动字段名称

Question

您好我正在使用Spring rest Template来命中POST API，并且工作正常。

问题是当我在MockRestServiceServer中使用它时。

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i，e：

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

当我尝试使用JSON正文

命中特定的POST网址时

{"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

任何人都可以帮助我，我在这里缺少什么？
