RestTemplate restTemplate = new RestTemplate()
restTemplate.setRequestFactory(new BufferingClientHttpRequestFactory(new SimpleClientHttpRequestFactory()))
restTemplate.setInterceptors([new LoggingRequestInterceptor()])

由于会多次读取request及response body，所以我们这里会使用BufferingClientHttpRequestFactory类来保证能够读取多次。
