背景

spring程序，使用的feign调用其他服务，结果抛异常：

  1. "Could not write request: no suitable HttpMessageConverter found for request type [com.ekeguan.tradefacade.pojo.req.PhpParams] and content type [application/x-www-form-urlencoded]"}
  2. feign.codec.EncodeException: Could not write request: no suitable HttpMessageConverter found for request type [com.ekeguan.tradefacade.pojo.req.PhpParams] and content type [application/x-www-form-urlencoded]
  3.     at org.springframework.cloud.openfeign.support.SpringEncoder.encode(SpringEncoder.java:151)
  4.     at feign.ReflectiveFeign$BuildEncodedTemplateFromArgs.resolve(ReflectiveFeign.java:380)
  5.     at feign.ReflectiveFeign$BuildTemplateByResolvingArgs.create(ReflectiveFeign.java:232)

看一下报错地方的代码：

  1. @RequestMapping(value = "/api/distribute/get"
  2.             , consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE
  3.             , method = RequestMethod.POST)
  4.     ApiResponse getOrderExpressList(PhpParams params);

解决方法：

  1. @Bean
  2.     Encoder feignFormEncoder(ObjectFactory<HttpMessageConverters> converters) { 
  3.         return new SpringFormEncoder(new SpringEncoder(converters));
  4.     }
