一、feign多参数问题

1.1GET方式

错误写法css

@RequestMapping(value="/test", method=RequestMethod.GET) Model test(final String name, final int age);

启动服务的时候，会报以下异常：java

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)

异常缘由：当使用Feign时，若是发送的是get请求，那么须要在请求参数前加上@RequestParam注解修饰，Controller里面能够不加该注解修饰。spring

正确写法springboot

@RequestMapping(value="/test", method=RequestMethod.GET) Model test(@RequestParam("name") final String name,@RequestParam("age") final int age);

1.1POST方式

错误写法restful

public int save(@RequestBody final Person p, @RequestBody final UserModel user);

feign中你能够有多个@RequestParam，但只能有不超过一个@RequestBody。app

正确写法less

public int save(@RequestBody final Person p,@RequestParam("userId") String userId,@RequestParam("userTel") String userTel);
