springcloud(九) springboot Actuator + admin 监控

前一章讲的都是Feign项目（调用方）的监控。接下来讲的是服务提供方的监控

一、springboot actuator + springboot admin

　　　　Spring Boot Admin 是一个管理和监控Spring Boot 应用程序的开源软件，它针对springboot的actuator接口进行UI美化封装

　　springboot admin 独立工程：

pom.xml:

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

     </dependency>
   </dependencies>

   <!-- 添加spring-boot的maven插件 -->
   <build>

   </build>
 </project>

SpringBootAdminApplication 启动类：

 package com.jiagoushi.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 //支持admin
 public class SpringBootAdminApplication {

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

启动之后是这样的：

什么都没有? 我们在启动一个服务提供者就有 了

user服务提供者：

和之前用的user服务最大区别就是application.yml:　

 server:
   port: 8001
 spring:
   application:
     name: microservice-provider-user
   boot:
     admin:
       url: http://localhost:9999        #注意这里：spring boot admin服务端地址，搜集客户端监控数据
   jpa:
     generate-ddl: false
     show-sql: true
     hibernate:
       ddl-auto: none
   datasource:                           # 指定数据源
     platform: h2                        # 指定数据源类型
     schema: classpath:schema.sql        # 指定h2数据库的建表脚本
     data: classpath:data.sql            # 指定h2数据库的数据脚本
 logging:                                # 配置日志级别，让hibernate打印出执行的SQL
   level:
     root: INFO
     org.hibernate: INFO
     org.hibernate.type.descriptor.sql.BasicBinder: TRACE
     org.hibernate.type.descriptor.sql.BasicExtractor: TRACE

 eureka:
   client:
     serviceUrl:
       defaultZone: http://localhost:8761/eureka/
   instance:
     prefer-ip-address: true
 
　　#这里配置actuaotr不能丢，不然springboot admin会没数据
 management:
   security:
     enabled: false  #关掉安全认证
   port: 8899  #管理端口调整成8888,独立的端口可以做安全控制 actuator的端口
   context-path: /monitor  #actuator的访问路径
   health:
     mail:
       enabled: false

　　ProviderUserApplication_08 启动类：

 package com.jiagoushi.cloud.study;

 import org.springframework.boot.SpringApplication;
 import org.springframework.boot.autoconfigure.SpringBootApplication;
 import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

 @EnableDiscoveryClient
 @SpringBootApplication
 public class ProviderUserApplication_08 {
   public static void main(String[] args) {
     SpringApplication.run(ProviderUserApplication_08.class, args);
   }
 }

启动之后再次访问spring boot admin  , 发现有一个user服务
