spring-boot admin的使用

spring boot admin为spring boot应用提供了整合的视图，应用的详情视图提供了应用本身及运行时环境（OS和JVM）运维比较关心的数据，应用的运行时信息，log输出，metrics统计，environment和logging level实时调整，thread线程运行时状态，trace，audit和Hystrix。同时提供了turbine扩展插件，用于整合展示整个集群的熔断器信息。在Journal模块，可以提供整个集群所有节点的状态变化历程。

首先是服务器端的代码如下

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  <artifactId>spring-boot-admin-server</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>jar</packaging>

  <properties>

  <dependencies>
    <dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-server</artifactId>
        <version>1.5.6</version>
    </dependency>
    <dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-server-ui</artifactId>
        <version>1.5.6</version>
    </dependency>
    <dependency> 
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
        <version>1.5.9.RELEASE</version>
    </dependency> 
  </dependencies>

  <!-- 添加spring-boot的maven插件 -->
  <build>
    <plugins>
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
      </plugin>
    </plugins>
  </build>
</project>

启动类的代码如下

package com.tuling.cloud.study;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Configuration;

import de.codecentric.boot.admin.config.EnableAdminServer;

@Configuration
@EnableAutoConfiguration
@EnableAdminServer
public class SpringBootAdminApplication {

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

然后看配置文件

application.yml

server:
  port: 9999 
spring:  
  application:  
    name: service-admin  
  mail:  
    host: smtp.163.com  
    username: aaronrao2018@163.com
    password: 2018shijiebei  
    properties:  
      mail.debug: false  
      mail.smtp.auth: true  
  boot:  
    admin:  
      notify:  
        mail:  
          to: 3376224996@qq.com  
          from: aaronrao2018@163.com  
#          ignore-changes: UNKNOWN:UP  
      routes:  
        endpoints: env,metrics,dump,jolokia,info,configprops,trace,logfile,refresh,flyway,liquibase,heapdump,loggers,auditevents,hystrix.stream

spring-admin发送邮件，需要添加下面的依赖

 <dependency> 
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
        <version>1.5.9.RELEASE</version>
    </dependency> 

application.yml

server:
  port: 9999 
spring:  
  application:  
    name: service-admin  
  mail:  
    host: smtp.163.com  
    username: aaronrao2018@163.com
    password: 2018shijiebei  
    properties:  
      mail.debug: false  
      mail.smtp.auth: true  
  boot:  
    admin:  
      notify:  
        mail:  
          to: 3376224996@qq.com  
          from: aaronrao2018@163.com  
#          ignore-changes: UNKNOWN:UP  
      routes:  
        endpoints: env,metrics,dump,jolokia,info,configprops,trace,logfile,refresh,flyway,liquibase,heapdump,loggers,auditevents,hystrix.stream

邮件发起者：

  username: aaronrao2018@163.com
    password: 2018shijiebei  
邮件接收方

   to: 3376224996@qq.com  
          from: aaronrao2018@163.com

一个应用存在多个实例，点击detail可以查看当前应用这个实例的详细信息，我们点击detail进去
