Question

在我的spring boot应用程序中，我通过RestTemplate得到以下格式的Json响应。但是，当我直接在浏览器中在url中测试相同时，我得到了正确的JSON响应。它是hello.gz格式。字符编码是否有问题？

我在applcation.properties中添加了以下几行。

spring.http.encoding.charset=UTF-8
# Enable http encoding support.
spring.http.encoding.enabled=true
# Force the encoding to the configured charset on HTTP requests and responses.
spring.http.encoding.force=true

Also I enabled GZip compression in Spring Boot

# Enable response compression
server.compression.enabled=true

# The comma-separated list of mime types that should be compressed
server.compression.mime-types=text/html,text/xml,text/plain,text/css,text/javascript,application/javascript,application/json

# Compress the response only if the response size is at least 1KB
server.compression.min-response-size=1024

下面是我的代码。

@GetMapping(value = { "/", "/hello" }, produces = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<String> hello() {

        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        HttpEntity<String> entity = new HttpEntity<String>(null, headers);

        RestTemplate restTemplate = new RestTemplate();
        //restTemplate.getMessageConverters().add(0, new StringHttpMessageConverter(Charset.forName("UTF-8")));
        ResponseEntity<String> entity2 = restTemplate.exchange(
                "https://XXXXX.8080/hello.gz", HttpMethod.GET, null,
                String.class);
        String body = entity2.getBody();

        System.out.println(body);

        return ResponseEntity.ok(body);
    }

Answer 1

将MediaType.APPLICATION_JSON_VALUE替换为MediaType.APPLICATION_JSON_UTF8_VALUE应该可以。

否则，请尝试将带有UTF-8字符集的消息转换器添加到RestTemplate：

RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters()
        .add(0, new StringHttpMessageConverter(Charset.forName("UTF-8")));
