java.lang.IllegalArgumentException: Not enough variable values available to expand '66'

配置springcloud的consumer的服务的controller层错误

    @RequestMapping("/findGenShenById")
    public GenShen findGenShenById(Integer uid) {
        System.out.println("how about this =========" + uid);
        return this.restTemplate.postForObject(URL_PREFIX+"/findGenShenById?uid={66}", uid, GenShen.class);
    }

 可以看到成功打印出来了所以就是后面post错误

解决的错误就是再次在后面加一个uid

 return this.restTemplate.postForObject(URL_PREFIX+"/findGenShenById?uid={66}", uid, GenShen.class,uid );

之后就可以解决了，
