caused by: java.lang.IllegalStateException: Method has too many Body parameters: 多参数问题

多参数问题

1. @RequestMapping(value="/user/name", method=RequestMethod.GET)
2.  

   User findByUsername(final String userName, final String address);

启动服务的时候，会报如下异常：

Caused by: java.lang.IllegalStateException: Method has too many Body parameters: public abstract com.chhliu.springboot.restful.vo.User com.chhliu.springboot.restful.feignclient.UserFeignClient.findByUsername(java.lang.String,java.lang.String)

异常原因：当使用Feign时，如果发送的是get请求，那么需要在请求参数前加上@RequestParam注解修饰，Controller里面可以不加该注解修饰。

上面问题的解决方案如下：

@RequestMapping(value="/user/name", method=RequestMethod.GET)
User findByUsername(@RequestParam("userName") final String userName, @RequestParam("address") final String address);
