如果访问share/1和share/2

sentinel后台会出现两种资源名，为share/1设置流控规则不会影响到share/2，这是很致命的，我们不可能每一种资源都去做流控，sentinel控制台不支持占位符

UrlCleaner

package com.itmuch.usercenter.sentineltest;

import com.alibaba.csp.sentinel.adapter.servlet.callback.UrlCleaner;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang.math.NumberUtils;
import org.springframework.stereotype.Component;

import java.util.Arrays;

@Component
@Slf4j
public class MyUrlCleaner implements UrlCleaner {
    @Override
    public String clean(String s) {

        String[] split = s.split("/");
        return Arrays.stream(split)
                .map(i->{
                    if (NumberUtils.isNumber(i)){
                        return "{number}";
                    }
                    return i;
                })
                .reduce((a,b)->a+'/'+b)
                .orElse("");
    }
}

该方法只是简单的将链接替换成占位符
