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
