not annotated with HTTP method type (ex. GET, POST) 問題解決

大多數情況是真的而沒有寫method = RequestMethod.GET、POST等注解, 有時這么寫了也報類似異常，如下

@FeignClient("microservice-provider-user")
public interface MyFeignClient {

    @RequestMapping(value = "a",method = RequestMethod.GET)
    public User findByIdE(@RequestParam("id") Long id);

    @RequestMapping(method = RequestMethod.POST,value = "/getUserByPost")
    User findBy(@RequestBody User user);
}

java.lang.IllegalStateException: Method findByIdE not annotated with HTTP method type (ex. GET, POST)

問題原因，是因為這個類的存在，在其中 new feign.Contract.Default();使用了默認的Contract導致。

package com.itmuch.cloud.study.user.feign;

import feign.Contract;
import feign.Logger;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class MyFeignConfiguration {

@Bean
public Contract feignContract(){
return new feign.Contract.Default();
}

@Bean
public Logger.Level logLevel(){
return Logger.Level.FULL;
}

}

解決方法：換其他Contract.
