sentinel热点流控与持久化

 

@SentinelResource热点名称随意，这里为abc，监控也监控bac，上面配置的是才懂第一个参数开始，qps>1就熔断

    @GetMapping("/testHotKey")
    @SentinelResource(value ="abc",blockHandler = "deal_testHotKey")//热键名称唯一
    public String testHotKey(@RequestParam(value ="p1",required = false)String p1,
                             @RequestParam(value ="p2",required = false)String p2){
        return "----testHotKey";
    }
    public String deal_testHotKey(String p1, String p2,BlockException blockException){
        return "----deal_testHotKey,o(╥﹏╥)o";

    }
