JSON無效的UTF-8中間字節(jié)

源碼算法與數(shù)據(jù)結(jié)構(gòu)

JSON無效的UTF-8中間字節(jié)當（Jackson，本例）JSON引擎嘗試解析一些未以UTF-8編碼的JSON時，會發(fā)生此錯誤。如何告訴引擎它應(yīng)該期望與UTF-8不同的東西，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);錯誤日志：Caused by: org.springframework.http.converter.HttpMessageNotReadableException: Could not read JSON: Invalid UTF-8 middle byte 0x20at [Source: org.apache.http.conn.EofSensorInputStream@44d397b0; line: 92, column: 42]; nested exception is org.codehaus.jackson.JsonParseException: Invalid UTF-8 middle byte 0x20at [Source: org.apache.http.conn.EofSensorInputStream@44d397b0; line: 92, column: 42]at org.springframework.http.converter.json.MappingJacksonHttpMessageConverter.readInternal(MappingJacksonHttpMessageConverter.java:138)at org.springframework.http.converter.AbstractHttpMessageConverter.read(AbstractHttpMessageConverter.java:154)at org.springframework.web.client.HttpMessageConverterExtractor.extractData(HttpMessageConverterExtractor.java:74)at org.springframework.web.client.RestTemplate$ResponseEntityResponseExtractor.extractData(RestTemplate.java:622)

TA貢獻1898條經(jīng)驗獲得超8個贊

我在Java客戶端應(yīng)用程序中得到了這個異常，我正在序列化這樣的JSON

String json = mapper.writeValueAsString(contentBean);

在服務(wù)器端，我使用Spring Boot作為REST端點。例外是：

嵌套異常是com.fasterxml.jackson.databind.JsonMappingException：無效的UTF-8起始字節(jié)0xaa

我的問題是，我沒有在HTTP客戶端上設(shè)置正確的編碼。這解決了我的問題：

updateRequest.setHeader("Content-Type", "application/json;charset=UTF-8");StringEntity entity= new StringEntity(json, "UTF-8");updateRequest.setEntity(entity);

Android設(shè)置內(nèi)容類型為HttpPost
