2、启动类加上@EnableAdminServer

import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.openfeign.EnableFeignClients;
/**
 * @author: Owen
 * @date: 2020/12/22
 * @description:服务监控管理
 */
@EnableAdminServer
@EnableFeignClients
@SpringBootApplication
@EnableDiscoveryClient
public class ServerManagerApplication {
    public static void main(String[] args) {
        SpringApplication.run(ServerManagerApplication.class, args);
    }
}

3、SecuritySecureConfig安全认证

package com.za.edu.config;
import de.codecentric.boot.admin.server.config.AdminServerProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;
import org.springframework.security.web.csrf.CookieCsrfTokenRepository;

/**
 * @Author: Owen
 * @Date: 2022/6/22
 * @Description:安全认证适配器
 */
@Configuration
public class SecuritySecureConfig extends WebSecurityConfigurerAdapter {

    private final String adminContextPath;

    public SecuritySecureConfig(AdminServerProperties adminServerProperties) {
        this.adminContextPath = adminServerProperties.getContextPath();
    }


    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // 登录成功处理类
        SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
        successHandler.setTargetUrlParameter("redirectTo");
        successHandler.setDefaultTargetUrl(adminContextPath + "/");

        http.authorizeRequests()
                //静态文件允许访问
                .antMatchers(adminContextPath + "/assets/**").permitAll()
                //登录页面允许访问
                .antMatchers(adminContextPath + "/login","/css/**","/js/**","/image/*").permitAll()
                //其他所有请求需要登录
                .anyRequest().authenticated()
                .and()
                //登录页面配置，用于替换security默认页面
                .formLogin().loginPage(adminContextPath + "/login").successHandler(successHandler).and()
                //登出页面配置，用于替换security默认页面
                .logout().logoutUrl(adminContextPath + "/logout").and()
                .httpBasic().and()
                .csrf()
                .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())
                .ignoringAntMatchers(
                        "/instances",
                        "/actuator/**");

    }

}

4、CorsConfig跨域配置

package com.za.edu.config;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;

/**
 *@Author Owen
 *@Date 2020/8/17
 *@Description跨域配置
 */
@Configuration
public class CorsConfig {

    @Bean
    public FilterRegistrationBean corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration config = new CorsConfiguration();
        config.setAllowCredentials(true);
        config.addAllowedOrigin("*");
        config.addAllowedHeader("*");
        config.addAllowedMethod("OPTIONS");
        config.addAllowedMethod("HEAD");
        config.addAllowedMethod("GET");
        config.addAllowedMethod("PUT");
        config.addAllowedMethod("POST");
        config.addAllowedMethod("DELETE");
        config.addAllowedMethod("PATCH");
        source.registerCorsConfiguration("/**", config);
        final FilterRegistrationBean bean = new FilterRegistrationBean(new CorsFilter(source));
        bean.setOrder(0);
        return bean;
    }
}

5、application.yml配置文件

server:
  port: 9088
  # SpringBoot Admin页面URL前缀
  servlet:
    context-path: /admin

spring:
  application:
    name: zaedu-server-manager

         #       enabled: false
         # Nacos (开启\关闭) 自动注册服务

       #================== SpringBoot Admin配置 ==================

        nacos:
          client:

6、log4j2.xml日志配置

3、定义消息体DingTalkMessage

package com.za.edu.bean;
import com.dingtalk.api.request.OapiRobotSendRequest;
import lombok.Data;
import java.util.List;

/**
* @Author: Owen
* @Date: 2022/6/30
* @Description:钉钉消息
*/
@Data
public class DingTalkMessage {
    //消息标题
    private String title;
    //密钥
    private String secret;
    //消息内容
    private String content;
    //消息类型
    private String msgType;
    //webhook服务地址
    private String webhook;
    //是否推送所有人
    private Boolean isAtAll;

    //指定对象
    private List<String> mobileList;

    //================= 链接消息 =================
    //链接消息 图片地址
    private String picUrl;
    //链接消息 跳转url地址
    private String messageUrl;

    //================= 卡片模板 图文带链接 =================
    //被@人的手机号。
    private List<String> atMobiles;
    //被@人的用户userid。
    private List<String> atUserIds;
    //批量链接
    private List<OapiRobotSendRequest.Links> links;

    //================= 按钮选择框消息 =================
    private  String btnOrientation;                //0：按钮竖直排列 1：按钮横向排列
    private  List<OapiRobotSendRequest.Btns> btns; //按钮链接
    public  DingTalkMessage(){
    }


}

4、定义MessageModeEnums消息模板

package com.za.edu.enums;


import lombok.extern.slf4j.Slf4j;

/**
 * @author: Owen
 * @date: 2021/6/8
 * @description:钉钉消息模板
 */
@Slf4j
public enum MessageModeEnums {
    //消息关键字（钉钉配置的自定义关键词,并且消息中必须包含该(自定义关键词) 才能发送成功!!!!）
    TITLE_SERVER_ALARM("服务进程异常通知","消息关键字(服务进程异常警报)"),
    TITLE_SERVER_STATUS("服务状态变更通知","消息关键字(服务状态变更通知)"),

    //消息类型
    MODE_TEXT("text","文本消息"),
    MODE_LINK("link","链接消息"),
    MODE_MARKDOWN ("markdown","图文链接消息"),
    MODE_FEED_CARD ("feedCard","卡片图文样式消息"),
    MODE_ACTION_CARD ( "actionCard","事件选择框样式消息");

    MessageModeEnums(String type, String explain) {
        this.type = type;
        this.explain = explain;
    }

    private String type;         //消息类型
    private String explain;      //操作详情


    public String getType() {
        return type;
    }

    public String getExplain() {
        return explain;
    }

    /**
     * @author: Owen
     * @date: 2021/6/8
     * @description:查看根据命令拿详情
     */
    public static String getValue(String type) {
        String result = null;
        try {
            for (MessageModeEnums enums : MessageModeEnums.values()) {
                //是否符合当前设备型号
                if (enums.getType().equals(type)) {
                    result = enums.getExplain();
                }
            }
        } catch (Exception e) {
            log.error("Message event get explain faild: " + e.getMessage());
        }
        return result;
    }
}

5、钉钉消息推送工具类DingTalkUtils

package com.za.edu.utils;

6、消息推送接口DingTalkMessageController

package com.za.edu.controller;
import com.dingtalk.api.response.OapiRobotSendResponse;
import com.za.edu.bean.DingTalkMessage;
import com.za.edu.returns.ApiResult;
import com.za.edu.utils.DingTalkUtils;
import com.za.edu.utils.ExceptionUtil;
import org.springframework.web.bind.annotation.*;
import java.util.Objects;

/**
 * @Author Owen
 * @Description钉钉消息通知
 * @Date 2020/10/12
 */
@RestController
@RequestMapping("/dingTalk/message")
public class DingTalkMessageController {


    /**
     * @Author Owen
     * @Description推送钉钉通知消息
     * @Date 2020/10/12
     */
    @PostMapping(value = "/pushInform")
    public ApiResult pushInform(@RequestBody DingTalkMessage message) {
        ExceptionUtil.isNull(message, "Message params not null！");
        OapiRobotSendResponse result = DingTalkUtils.sendMessage(message);
        return ApiResult.successWithObject(Objects.isNull(result) ? null : result.getCode());
    }


}

7、启动第一个客户端（通知项目zaedu-inform）

在这里插入图片描述

======== Admin服务端整合项目服务监听事件

1、TaluohuiNotifier 服务监听通知类

2、跨服务调用钉钉通知

package com.za.edu.client;

@FeignClient("zaedu-inform")
public interface InformServiceClient {
    /**

     */
    @RequestMapping(value = "/dingTalk/message/pushInform", method = RequestMethod.POST, produces = {"application/json"}, consumes = {"application/excel+json"})
    ApiResult pushInform(@RequestBody DingTalkMessage message);

}
