Spring Boot Admin

Spring Boot Admin 是一个管理和监控 Spring Boot 应用程序的开源软件, 每个应用都认为是一个客户端, 通过 HTTP 或者使用 Eureka 注册到 admin server 中进行展示, Spring Boot Admin UI 部分使用 vue.js 将数据展示在前端.

Spring Boot Admin 分为:

服务端是一个监控后台用来汇总展示所有的监控信息

客户端就是具体的应用

1.server 和 client 的模式

(1)server 端

添加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
      <groupId>de.codecentric</groupId>
      <artifactId>spring-boot-admin-starter-server</artifactId>
      <version>2.1.6</version>
</dependency>

配置

server.port=8000
spring.application.name=Admin Server

启动类

package com.example.management;
import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@EnableAdminServer
public class ManagementApplication {
    public static void main(String[] args) {
        SpringApplication.run(ManagementApplication.class, args);
    }
}

(2)client 端

添加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-Web</artifactId>
</dependency>
<dependency>
    <groupId>de.codecentric</groupId>
    <artifactId>spring-boot-admin-starter-client</artifactId>
    <version>2.1.6</version>
</dependency>

配置

server.port=8001
spring.application.name=Admin Client
spring.boot.admin.client.url=http://localhost:8000
management.endpoints.Web.exposure.include=*
management.endpoint.health.show-details=always

启动类

package com.example.client;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class ClientApplication {
    public static void main(String[] args) {
        SpringApplication.run(ClientApplication.class, args);
    }
}

注:

使用时需要先启动服务端, 在启动客户端的时候打开 Actuator 的接口, 并指向服务端的地址

2. 基于 springcloud 的模式

(1)server

在 server 端加入 @EnableDiscoveryClient 注解, SBA 就会主动去拉取注册中心的注册服务列表, 从而获取他们的服务动态信息

注册中心使用 Eureka

添加依赖

<dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
      <version>2.1.3.RELEASE</version>
</dependency>

配置

server.port=8000
spring.application.name=Admin Server
eureka.instance.hostname=localhost
eureka.instance.lease-renewal-interval-in-seconds=10
eureka.instance.prefer-ip-address=true
eureka.client.registry-fetch-interval-seconds=5
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
eureka.client.service-url.default-zone=${
	EUREKA_SERVICE_URL:http://localhost:8761	
}/eureka/

启动类

package com.example.management;
import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
@SpringBootApplication
@EnableAdminServer
@EnableDiscoveryClient
public class ManagementApplication {
    public static void main(String[] args) {
        SpringApplication.run(ManagementApplication.class, args);
    }
}

启动服务就可以看到注册到注册中心的服务都会被监控
