springBootAdmin监控

简介

用于对 Spring Boot 应用的管理和监控。可以用来监控服务是否健康、是否在线、以及一些jvm数据等等

Spring Boot Admin 分为服务端(spring-boot-admin-server)和客户端(spring-boot-admin-client)，服务端和客户端之间采用 http 通讯方式实现数据交互；单体项目中需要整合 spring-boot-admin-client 才能让应用被监控

在 SpringCloud 项目中，spring-boot-admin-server 是直接从注册中心抓取应用信息，不需要每个微服务应用整合 spring-boot-admin-client 就可以实现应用的管理和监控

单体项目

服务端

引入spring-boot-admin服务端依赖

	  <!--用于检查系统的监控情况-->
 <dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-actuator</artifactId>
 </dependency>
  <!--Spring Boot Admin Server监控服务端-->
 <dependency>
     <groupId>de.codecentric</groupId>
     <artifactId>spring-boot-admin-starter-server</artifactId>
     <version>2.3.1</version>
 </dependency>
   <!--增加安全防护，防止别人随便进-->
 <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-security</artifactId>
  </dependency>

启动类上开启admin@EnableAdminServer

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