Spring Boot添加admin监控

什么是Spring Boot Admin？

Spring Boot Admin是一个用于管理和监控Spring Boot应用程序的Web应用程序。应用程序通过我们的Spring Boot Admin Client（通过HTTP）注册，或者使用Spring Cloud（例如Eureka, Consul）进行注册。

入门

设置Admin Server服务

添加Spring Boot Admin Server starter依赖:

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

在主配置类上添加@EnableAdminServer注解启用Server:

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

注册客户端应用

Spring Boot Admin Client

添加spring-boot-admin-starter-client依赖:

<dependency>
  <groupId>de.codecentric</groupId>
  <artifactId>spring-boot-admin-starter-client</artifactId>
  <version>${spring-boot-admin.version}</version>
</dependency>

配置Spring Boot Admin Server的URL已注册应用:

1 2	spring.boot.admin.client.url=http://localhost:8080 management.endpoints.web.exposure.include=*

使用 Spring Cloud Discovery 注册

添加spring-cloud-starter-eureka依赖:

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

添加@EnableDiscoveryClient注解启用服务发现:

@Configuration
@EnableAutoConfiguration
@EnableDiscoveryClient
@EnableAdminServer
public class SpringBootAdminApplication {
  public static void main(String[] args) {
    SpringApplication.run(SpringBootAdminApplication.class, args);
  }
}

配置服务发现地址:

eureka:
  instance:
    leaseRenewalIntervalInSeconds: 10
    health-check-url-path: /actuator/health
    metadata-map:
      startup: ${random.int} #needed to trigger info and endpoint update after restart
  client:
    registryFetchIntervalSeconds: 5
    serviceUrl:
      defaultZone: ${EUREKA_SERVICE_URL:http://localhost:8761}/eureka/

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