Spring Cloud 学习 Spring Boot Admin

Posted 2022-01-15 victorbu

Spring Boot Admin 用于管理和监控一个或者多个 Spring Boot 程序

新建 spring-boot-admin-server

pom

<parent>
    <artifactId>spring-cloud-parent</artifactId>
    <groupId>com.karonda</groupId>
    <version>1.0.0</version>
</parent>
<modelVersion>4.0.0</modelVersion>

<artifactId>spring-boot-admin-server</artifactId>

<dependencies>
    <dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-starter-server</artifactId>
        <version>RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    </dependency>
</dependencies>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

spring-boot-admin-starter-server 需要指定版本号

application.yml

server:
  port: 8071

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8001/eureka/

spring:
  application:
    name: admin-server

启动类

@EnableAdminServer // 开启 Admin Server
@EnableEurekaClient
@SpringBootApplication
public class AdminServerApp 
    public static void main(String[] args)
        SpringApplication.run(AdminServerApp.class, args);
    

eureka-client

添加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

注册 Spring Boot Admin (SBA) 客户端有两种方式：一种是通过引入 SBA Client (spring-boot-admin-starter-client)；另一种是基于 Spring Cloud Discovery, 不需要添加依赖

application.xml 添加

management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: ALWAYS

测试

1. 启动 eureka-server
2. 启动 config-server
3. 启动 eureka-client
4. 启动 admin-server

访问 http://localhost:8071
