Spring Boot Admin 2.1.4最新实战教程

环境的搭建

首先搭建eruka的注册中心

application.yml

server:
  port: 8761                    # 指定该Eureka实例的端口
eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

EurekaApplication启动类

package com.tuling.cloud.study;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

/**
 * 使用Eureka做服务发现.
 */
@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication {
  public static void main(String[] args) {
    SpringApplication.run(EurekaApplication.class, args);
  }
}

接下来我们来看admin sererhttps://blog.csdn.net/a1036645146/article/details/97249153

参考博客：https://blog.csdn.net/a1036645146/article/details/97249153

Spring Boot Admin是一个社区项目，用于管理和监视基于SpringBoot的应用程序。客户端应用可以通过Spring Boot Admin Client或者注册中心就可以注册到Spring Boot Admin服务端进行监控。Spring Boot Admin 是在 Spring Boot Actuator 的基础上提供简洁的可视化 WEB UI。2.X版本使用Vue.js重写了UI界面，简洁。

2.3 修改application.yml配置文件,端口可以自己修改: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"

        </dependency>
 
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        
        <!-- eureka注册中心-->
            <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
                     <version>2.0.2.RELEASE</version>
            </dependency>


    </dependencies>
 
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
 
</project>

2.2 启动类添加相关注解，@EnableAdminServer：

package com.tuling.cloud.study;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.context.annotation.Configuration;

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



@Configuration
@EnableAutoConfiguration
@EnableAdminServer
@EnableDiscoveryClient
public class SpringBootAdminApplication {

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

2.3 修改application.yml配置文件,端口可以自己修改:

 
server:
  port: 6666
spring:
  application:
    name: SpringBootAdmin
  boot:
    admin:
      ui:
        title: SpringBootAdmin-Server
 
# eureka注册中心
#eureka:
#  client:
#    serviceUrl:
#      defaultZone: http://localhost:1001/eureka/
 
#Actuator配置：暴露敏感路径，默认情况下，敏感路径并不暴露
management:
  endpoints:
    web:
      exposure:
        # 暴露xxx端点，如需暴露多个，用,分隔；如需暴露所有端点，用'*'
        include: "*"
  endpoint:
    health:
      # 是否展示健康检查详情
      show-details: ALWAYS
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
  instance:
    prefer-ip-address: true

2.4 启动服务端应用：启动先启动注册中心，然后在启动admin server

admin Server应用已经把自己注册上到了注册中心，同时也监控了自己

 接下来，我们要让admin server监控其他客户端应用， Spring Boot Admin Client 客户端搭建 同样创建一个Springboot 应用，基于2.1.4版本,pom依赖如下：

pom.xml如下

application.yml如下

server:
  port: 8888
 
spring:
  boot:
    admin:
      client:
        # server地址
        url: http://localhost:6666
        instance:
          #client地址
          service-base-url: http://localhost:${server.port}
  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          
  application:
    name: SpringBootAdmin-Client
  main:
    allow-bean-definition-overriding: true
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
  instance:
    prefer-ip-address: true          
 
#Actuator配置：暴露敏感路径，默认情况下，敏感路径并不暴露
management:
  endpoints:
    web:
      exposure:
        # 暴露xxx端点，如需暴露多个，用,分隔；如需暴露所有端点，用'*'
        include: "*"
  endpoint:
    health:
      # 是否展示健康检查详情
      show-details: ALWAYS
 
# info信息会显示到SpringBootAdmin的server端，这里取的是pom文件中的数据
info:
  version: @project.version@
  groupId: @project.groupId@
  artifactId: @project.artifactId@
  

这里需要特别需要特别强调的是，因为admin server是注册在了注册中心上面，admin server 的客户端如果也注册到了注册中心上面， -admin-starter-client会从注册中心获得admin Server的地址，所以上面的

 不要在手动指定admin server的地址，这里写成下面的形式

server:
  port: 4444
 
spring:
  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          
  application:
    name: user
  main:
    allow-bean-definition-overriding: true
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
  instance:
    prefer-ip-address: true          
 
#Actuator配置：暴露敏感路径，默认情况下，敏感路径并不暴露
management:
  endpoints:
    web:
      exposure:
        # 暴露xxx端点，如需暴露多个，用,分隔；如需暴露所有端点，用'*'
        include: "*"

data.sql

insert into user (id, username, name, age, balance) values (1, 'account1', '张三', 20, 100.00);
insert into user (id, username, name, age, balance) values (2, 'account2', '李四', 28, 180.00);
insert into user (id, username, name, age, balance) values (3, 'account3', '王五', 32, 280.00);

schema.sql

drop table user if exists;
create table user (id bigint generated by default as identity, username varchar(40), name varchar(20), age int(3), balance decimal(10,2), primary key (id));

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

3.3 启动客户端应用，显示已注册上,选项内容挺丰富的，具体自己运行去看下：
