springboot monitor 监控中心搭建

创建监控中心,在这之前需要已经有了eureka注册中心。
EnableAdminServer 表示为监控中心
EnableDiscoveryClient表示为监控的客户端

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

```java
server:
  port: 28762
spring:
  security:
    user:
      name: admin
      password: admin
  application:
    name: springboot-monitor
management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: always

eureka:
  instance:
    lease-expiration-duration-in-seconds: 30 # 心跳,租约续约频率,单位:秒
    lease-renewal-interval-in-seconds: 10 #  eureka server多久没有收到心跳,则表示对应的实例过期,单位:秒。
    health-check-url-path: /actuator/health
    statusPageUrlPath: /actuator/health
    prefer-ip-address: true #以IP地址注册到服务中心,相互注册使用IP地址
    # ip-address: 127.0.0.1 #强制指定IP地址,默认会获取本机的IP地址
    instance-id: ${spring.application.name}:${spring.cloud.client.ip-address}:${server.port}
  client:
    fetch-registry: true #通过设置fetch-registry与register-with-eureka 表明自己是一个eureka服务
    register-with-eureka: true #服务注册中心也会将自己作为客户端来尝试注册自己,为true(默认)时自动生效
    service-url:
      defaultZone: http://localhost:28761/eureka/

pom配置

      <dependency>
            <groupId>de.codecentric</groupId>
            <artifactId>spring-boot-admin-starter-server</artifactId>
            <version>2.4.1</version>
        </dependency>

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

之后是创建客户端 ,基本和监控中心差不多,但是需要注意的是如果配置了servlet 路径,需要在eureka 里面额外指定出来,不然监控不到很多数据。

启动类

@EnableTransactionManagement
@MapperScan("com.aaa.aaa.aaa.mapper")
@EnableCircuitBreaker
**@EnableEurekaClient**
@EnableFeignClients(basePackages ={"com.aaa.*"})
@ComponentScan(basePackages = {"com.aaa.aaa.*"})
@SpringBootApplication
public class DeviceApplication {

    public static void main(String[] args) {
        SpringApplication.run(DeviceApplication.class, args);
    }
spring:
  application:
    name: baop-device

server:
  port: 8888
  servlet:
    context-path: /device #注意这个对监控的影响

management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: ALWAYS
#上面两段配置就是支持admin监控的配置
eureka:
  instance:
    lease-expiration-duration-in-seconds: 30 # 心跳,租约续约频率,单位:秒
    lease-renewal-interval-in-seconds: 10 #  eureka server多久没有收到心跳,则表示对应的实例过期,单位:秒。
    health-check-url-path: /actuator/health
    statusPageUrlPath: /actuator/health
    prefer-ip-address: true #以IP地址注册到服务中心,相互注册使用IP地址
    instance-id: ${spring.application.name}:${spring.cloud.client.ip-address}:${server.port}
    metadata-map:
      management:
        context-path: ${server.servlet.context-path}/actuator#注意这个配置 如果没有就不用配置 其他都是常见的eureka配置
  client:
    fetch-registry: true #通过设置fetch-registry与register-with-eureka 表明自己是一个eureka服务
    register-with-eureka: true #服务注册中心也会将自己作为客户端来尝试注册自己,为true(默认)时自动生效
    service-url:
      defaultZone: http://localhost:28761/eureka/
 <dependency>
                <groupId>de.codecentric</groupId>
                <artifactId>spring-boot-admin-starter-client</artifactId>
                <version>2.4.1</version>
            </dependency>
