                        <p>客户端还能  {pid} 这么写？</p>
                

                        GetMapping("/findById/{pid}")  额，这不对吗，Rest接受的啊，在方法上写的，是不是jar包的事啊
                    

                    <p>把你代码贴出来哈</p>
                

                    <p>45个字符 应该是'{'符号  代码问题吧 估计少了个注解 @PathVariable</p>
                

                        写了，在方法里有 @PathVariable("pid") Long pid  ，可以接受到id值，就是在调用服务的时候就报错，感觉应该是jar冲突了
                    

                    <p>直接访问下这个接口 正常与否</p>
                

                        能访问到，就是通过 feign 调用报错
                    

                    <p>我用 RestTemplate 都可以调到后台，就是 feign 不行，不知道怎么搞得 jar 包引得是</p> 

    spring-cloud-starter-openfeign 啊，没有错啊，服了，太耽误时间了

     

                            调用这里的请求参数正确不 查查参数
                    

                    <p>我看 pom.xml了  Maven Helper 中看 guava 里的 jar 报错，这是什么包</p>
                

                    <p>代码贴一下啊</p>
                

                    <p>所以到底是啥问题，我也出现这个问题了，求解</p>
