开始

1. rely
   ps：官方wiki里面的demo使用的版本是2.1.6的springboot，我这边使用的是2.2.7的。经过测试，发现没有影响，demo代码可以直接拿来用

   <dependency>
       <groupId>com.alibaba.csp</groupId>
       <artifactId>sentinel-apache-dubbo-adapter</artifactId>
       <version>1.6.3</version>
   </dependency>
   <dependency>
       <groupId>com.alibaba.cloud</groupId>
       <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
       <version>2.1.0.RELEASE</version>
   </dependency>
   
   <!-- 基础依赖 包含 mvc,aop 等jar资源 -->
   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-web</artifactId>
   </dependency>
   

2. Code and configuration files

• controller

  import com.alibaba.csp.sentinel.slots.block.SentinelRpcException;
  import org.springframework.web.bind.annotation.GetMapping;
  import org.springframework.web.bind.annotation.RequestParam;
  import org.springframework.web.bind.annotation.RestController;
  
  /**
   * @author ：qilong sun
   * @date ：Created in 2020/7/16 9:54
   * @description：
   * @modified By：
   * @version: V1.0$
   */
  @RestController
  public class IndexController {
        
        
      @GetMapping("/hello")
      public String apiSayHello(@RequestParam String name) {
        
        
          try {
        
        
              return "你好";
          } catch (SentinelRpcException e) {
        
        
              e.getCause().printStackTrace();
              return "oops, blocked by Sentinel...";
          } catch (Exception ex) {
        
        
              ex.printStackTrace();
              return "oops...";
          }
      }
  
      @GetMapping("/test")
      public String test() {
        
        
          return "我是test" + System.currentTimeMillis();
      }
  }
  

• When the startup class starts, you need to copy the code between the above "{}" to the jvm configuration

  import org.springframework.boot.SpringApplication;
  import org.springframework.boot.autoconfigure.SpringBootApplication;
  
  /**
   *  Run with: {@code -Dcsp.sentinel.api.port=8723 -Dcsp.sentinel.dashboard.server=localhost:8080 -Dproject.name=web-demo}.
   */
  @SpringBootApplication(scanBasePackages = "com.demo.*")
  public class SentinelDemoServer01App {
        
        
      public static void main(String[] args) {
        
        
          SpringApplication.run(SentinelDemoServer01App.class, args);
          System.out.println("启动成功...");
      }
  }
  

• Configuration file

  # base
  server.port=9526
  spring.application.name=sentinel-demo-server01
  
  # sentinel
  ## 指定sentinel控制台地址
  spring.cloud.sentinel.transport.dashboard=localhost:8080
  

3. start up
   
4. Registration (no error is reported, generally means success)
   
   
5. Access control panel
   

OK, this is basically done
