向ResponseEntity添加UTF-8编码

Question

我responseEntity喜欢这个:

HttpHeaders requestHeaders = new HttpHeaders();
requestHeaders.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
requestHeaders.setContentType(MediaType.valueOf("text/plain;charset=UTF-8"));

HttpEntity requestEntity = new HttpEntity(jsonQuery, requestHeaders);
ResponseEntity<String> responseEntity = restTemplate.exchange(url, HttpMethod.POST, requestEntity, String.class);

//Not in UTF-8!!
logger.debug("result: " + responseEntity.getBody());

但它没有编码UTF-8并产生这样的字符:Soci?.是否有可能UTF-8在restTemplate中以某种方式进行编码或添加编码？

Answer 1

requestHeaders .add("Content-Type", "text/html; charset=utf-8");

Answer 2

解决方案是在bean 中添加一个StringHttpMessageConverterwith ，如下所示：utf-8restTemplate

@Bean
public RestTemplate restTemplate() {
    RestTemplate restTemplate = new RestTemplate();
    restTemplate.getMessageConverters()
            .add(0, new StringHttpMessageConverter(Charset.forName("UTF-8")));
    return restTemplate;
}
