• 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:

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

    36       </plugin>
    37     </plugins>
    38   </build>
    39 </project>

    SpringBootAdminApplication 启动类:

     1 package com.jiagoushi.cloud.study;
     2 
     3 import org.springframework.boot.SpringApplication;
     4 import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
     5 import org.springframework.context.annotation.Configuration;
     6 
     7 import de.codecentric.boot.admin.config.EnableAdminServer;
     8 
     9 @Configuration
    10 @EnableAutoConfiguration
    11 @EnableAdminServer //支持admin
    12 public class SpringBootAdminApplication {
    13 
    14   public static void main(String[] args) {
    15     SpringApplication.run(SpringBootAdminApplication.class, args);
    16   }
    17 }

     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:

    pom.xml:

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

    16   </parent>
    17

    和之前用的user服务最大区别就是application.yml: 

     1 server:
     2   port: 8001
     3 spring:
     4   application:
     5     name: microservice-provider-user
     6   boot:
     7     admin:
     8       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
     9   jpa:
    10     generate-ddl: false
    11     show-sql: true
    12     hibernate:
    13       ddl-auto: none
    14   datasource:                           # 指定数据源
    15     platform: h2                        # 指定数据源类型
    16     schema: classpath:schema.sql        # 指定h2数据库的建表脚本
    17     data: classpath:data.sql            # 指定h2数据库的数据脚本
    18 logging:                                # 配置日志级别,让hibernate打印出执行的SQL
    19   level:
    20     root: INFO
    21     org.hibernate: INFO
    22     org.hibernate.type.descriptor.sql.BasicBinder: TRACE
    23     org.hibernate.type.descriptor.sql.BasicExtractor: TRACE
    24 
    25 eureka:
    26   client:
    27     serviceUrl:
    28       defaultZone: http://localhost:8761/eureka/
    29   instance:
    30     prefer-ip-address: true
    31 
      #这里配置actuaotr不能丢,不然springboot admin会没数据 32 management: 33 security: 34 enabled: false #关掉安全认证 35 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 36 context-path: /monitor #actuator的访问路径 37 health: 38 mail: 39 enabled: false

      ProviderUserApplication_08 启动类:

     1 package com.jiagoushi.cloud.study;
     2 
     3 import org.springframework.boot.SpringApplication;
     4 import org.springframework.boot.autoconfigure.SpringBootApplication;
     5 import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
     6 
     7 @EnableDiscoveryClient
     8 @SpringBootApplication
     9 public class ProviderUserApplication_08 {
    10   public static void main(String[] args) {
    11     SpringApplication.run(ProviderUserApplication_08.class, args);
    12   }
    13 }

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