RestTemplate中文乱码问题
在做springboot项目本地test测试时发现出现请求参数和返回值乱码问题,过滤器和yml文件中设置的utf-8编码都不起左右,可是使用postman请求时发现请求参数和返回值编码正常,一顿debug找原因最后发现是restemplate出现乱码,原代码如下:
1 @Test 2 public void getGoodsContent() { 3 RestTemplate restTemplate = new RestTemplate(); 4 MediaType type = MediaType.parseMediaType("application/json;charset=UTF-8"); 5 6 HttpHeaders headers = new HttpHeaders(); 7 headers.setContentType(type); 8 headers.add("Accept", MediaType.APPLICATION_JSON.toString()); 9 10 String paramter = "{'cityName': '北京'}"; 11 HttpEntity<String> entity = new HttpEntity<String>(paramter); 12 13 String json = restTemplate.postForObject("http://localhost:10013/goods/getGoodsContent", entity, String.class); 14 System.out.println(json); 15 }
修改后:
@Test public void getGoodsContent() { RestTemplate restTemplate = new RestTemplate(); // 设置restemplate编码为utf-8 restTemplate.getMessageConverters().set(1,new StringHttpMessageConverter(StandardCharsets.UTF_8)); MediaType type = MediaType.parseMediaType("application/json;charset=UTF-8"); HttpHeaders headers = new HttpHeaders(); headers.setContentType(type); headers.add("Accept", MediaType.APPLICATION_JSON.toString()); String paramter ="{'cityName': '北京'}"; HttpEntity<String> entity = new HttpEntity<String>(paramter); String json = restTemplate.postForObject("http://localhost:10013/goods/getGoodsContent", entity, String.class); System.out.println(json); }
增加了 restTemplate.getMessageConverters().set(1,new StringHttpMessageConverter(StandardCharsets.UTF_8));代码,意思是设置restemplate编码为utf-8,因为不设置此编码,restemplate底层是默认使用ISO-8859-1编码,所以在请求发送出去后编码格式并不是utf-8,此时在接收端即使用了编码过滤器也没有作用
