Sentinel系列之（三）初始化演示工程

初始化演示工程

1. 构建cloudalibaba-sentinel-service8401

建Module【cloudalibaba-sentinel-service8401】

改POM

主启动

package com.atguigu.springcloud.alibaba;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@EnableDiscoveryClient
@SpringBootApplication
public class MainApp8401
{
    public static void main(String[] args) {
        SpringApplication.run(MainApp8401.class, args);
    }
}

业务类

package com.atguigu.springcloud.alibaba.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class FlowLimitController {
    @GetMapping("/testA")
    public String testA() {
        return "------testA";
    }

    @GetMapping("/testB")
    public String testB() {

        return "------testB";
    }
}
