feignCould not write request: no suitable HttpMessageConverter found for request type

背景

spring程序，使用的feign调用其他服务，结果抛异常：

"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]"}
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]
	at org.springframework.cloud.openfeign.support.SpringEncoder.encode(SpringEncoder.java:151)
	at feign.ReflectiveFeign$BuildEncodedTemplateFromArgs.resolve(ReflectiveFeign.java:380)
	at feign.ReflectiveFeign$BuildTemplateByResolvingArgs.create(ReflectiveFeign.java:232)

看一下报错地方的代码：

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

解决方法：

    @Bean
    Encoder feignFormEncoder(ObjectFactory<HttpMessageConverters> converters) {
        return new SpringFormEncoder(new SpringEncoder(converters));
    }
