Spring Boot OpenFeign Get 请求 415 解决方法
Spring Boot OpenFeign About 3,329 wordsOpenFeign Client
User
对象想转为QueryString
请求参数。
@FeignClient(name = "user-client", url = "http://localhost:8080")
public interface MyOpenFeign {
@GetMapping("/user")
Integer getUser(User user);
}
报错信息
但是等到报错信息415
,不支持的Media Type
。
Caused by: feign.FeignException$UnsupportedMediaType: [415] during [GET] to [http://localhost:8080/user] [MyOpenFeign#getUser(UserRequest)]: [{"timestamp":"2022-11-02T02:45:27.940+00:00","status":415,"error":"Unsupported Media Type","path":"/user"}]

OpenFeign 详细日志
开启OpenFeign
详细日志,发现QueryString
变为了JSON
格式上传,Content-Type
也变为了application/json
,所以路由到了另外一个接口上了。
[MyOpenFeign#getUser] ---> GET http://localhost:8080/user HTTP/1.1
[MyOpenFeign#getUser] Content-Length: 28
[MyOpenFeign#getUser] Content-Type: application/json
[MyOpenFeign#getUser]
[MyOpenFeign#getUser] {"userId":"123","info":null}
[MyOpenFeign#getUser] ---> END HTTP (28-byte body)
[MyOpenFeign#getUser] <--- HTTP/1.1 415 (59ms)
[MyOpenFeign#getUser] accept: multipart/form-data
[MyOpenFeign#getUser] connection: keep-alive
[MyOpenFeign#getUser] content-type: application/json
[MyOpenFeign#getUser] date: Wed, 02 Nov 2022 03:08:46 GMT
[MyOpenFeign#getUser] keep-alive: timeout=60
[MyOpenFeign#getUser] transfer-encoding: chunked
[MyOpenFeign#getUser]
[MyOpenFeign#getUser] {"timestamp":"2022-11-02T03:08:46.440+00:00","status":415,"error":"Unsupported Media Type","path":"/user"}
[MyOpenFeign#getUser] <--- END HTTP (106-byte body)
解决方法
添加OpenFeign
中提供的@SpringQueryMap
注解,使对象转为QueryString
请求参数。
@FeignClient(name = "user-client", url = "http://localhost:8080")
public interface MyOpenFeign {
@GetMapping("/user")
Integer getUser(@SpringQueryMap User user);
}
查看OpenFeign
日志,发现请求参数直接拼接在URL
路径上了。

[MyOpenFeign#multipartUploadPartValid] ---> END HTTP (0-byte body)
