APPLICATION_FORM_URLENCODED_VALUE引发的no suitable HttpMessageConverter found for

 

轻松解决feign.codec.EncodeException: Could not write request: no suitable HttpMessageConverter found for

 

问题：使用feign client访问其他服务时，报错：feign.codec.EncodeException: Could not write request: no suitable HttpMessageConverter found for request type [com.example.demo.feignclient.DTO] and content type [application/x-www-form-urlencoded]

原因：没有找到合适的HttpMessageConverter转换为com.example.demo.feignclient.DTO实体类

报错前的代码：

@FeignClient(value = "ss", url = "http://localhost:9000")
public interface TestFeignClient {

@PostMapping(value = "/test", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
String test(DTO dto);

}
解决后的代码：

@FeignClient(value = "ss", url = "http://localhost:9000")
public interface TestFeignClient {

@PostMapping(value = "/test", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
String test(MultiValueMap<String, Object> dto);

}
测试代码：

@RestController
public class TestClientController {

@Autowired
private TestFeignClient feignClient;

@GetMapping(value = "/client")
public String test() {
MultiValueMap<String, Object> map = new LinkedMultiValueMap<>();
map.add("name", "sxp");
feignClient.test(map);
return "ok";
}
}
