JSON无效的UTF-8中间字节

Question

JSON无效的UTF-8中间字节

当（Jackson，本例）JSON引擎尝试解析一些未以UTF-8编码的JSON时，会发生此错误。

如何告诉引擎它应该期望与UTF-8不同的东西，例如UTF-16？

HttpHeaders requestHeaders = createSomeHeader();

RestTemplate restTemplate = new RestTemplate();

HttpEntity<?> requestEntity = new HttpEntity<Object>(requestHeaders);

String url = "someurl"

ResponseEntity<MyObject[]> arrayResponseEntity = restTemplate.exchange(url, HttpMethod.GET, requestEntity, MyObject[].class);

错误日志：

Caused by: org.springframework.http.converter.HttpMessageNotReadableException: Could not read JSON: Invalid UTF-8 middle byte 0x20

我在Java客户端应用程序中得到了这个异常，我正在序列化这样的JSONString&nbsp;json&nbsp;=&nbsp;mapper.writeValueAsString(contentBean);在服务器端，我使用Spring Boot作为REST端点。例外是：嵌套异常是com.fasterxml.jackson.databind.JsonMappingException：无效的UTF-8起始字节0xaa我的问题是，我没有在HTTP客户端上设置正确的编码。这解决了我的问题：updateRequest.setHeader("Content-Type",&nbsp;"application/json;charset=UTF-8");StringEntity&nbsp;entity=&nbsp;new&nbsp;StringEntity(json,&nbsp;"UTF-8");updateRequest.setEntity(entity);Android设置内容类型为HttpPost

我在不同平台之间不一致地遇到了这个问题，因为我从Mapper获得了JSON作为String并自己完成了写作。有时它作为ansi进入文件，其他时候正确地作为UTF8。我切换到了mapper.writeValue(file,&nbsp;data);让Mapper执行文件操作，它开始正常工作。
