springBootAdmin监控内存日志堆栈

概述

我的spring-boot版本：2.7.7
我的spring-boot-admin版本：2.7.10
jdk:1.8

平时测试环境服务不多的情况下，用linux命令看下日志和堆栈也不麻烦。但是要是服务数量上来了，有10几个服务这个时候用命令看已经有点麻烦了。特别是对于上了微服务的项目来说，服务更多。

可以用springBootAdmin方便我们日常监控服务情况.

springBootAdmin大致就是起一个服务端接收客户端的注册，然后通过利用springboot的actuator接口抓取客户端的具体服务信息.

server

先上pom依赖，我这边对应的版本号声明在父pom的dependencyManagement中了，要单独部署的话，需要声明下version.

        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starterartifactId>
        dependency>

        <dependency>
            <groupId>de.codecentricgroupId>
            <artifactId>spring-boot-admin-starter-serverartifactId>
        dependency>

        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-webartifactId>
        dependency>


        
        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-securityartifactId>
        dependency>

yml配置
为了安全搞了个密码，需要配置下拦截器

server:
  port: 9090
spring:
  application:
    name: adminserver
  security:
    user:
      name: admin
      password: ccc123456

拦截器

package com.xxx.xxx.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;

@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 {
        SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
        successHandler.setTargetUrlParameter("redirectTo");
        successHandler.setDefaultTargetUrl(adminContextPath + "/");
        http.authorizeRequests()
                //1.配置所有静态资源和登录页可以公开访问
                .antMatchers(adminContextPath + "/assets/**").permitAll()
                .antMatchers(adminContextPath + "/login").permitAll()
                .anyRequest().authenticated()
                .and()
                //2.配置登录和登出路径
                .formLogin().loginPage(adminContextPath + "/login").successHandler(successHandler).and()
                .logout().logoutUrl(adminContextPath + "/logout").and()
                //3.开启http basic支持，admin-client注册时需要使用
                .httpBasic().and()
                .csrf()
                //4.开启基于cookie的csrf保护
                .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())
                //5.忽略这些路径的csrf保护以便admin-client注册
                .ignoringAntMatchers(
                        adminContextPath + "/instances",
                        adminContextPath + "/actuator/**"
                );
    }

}

然后访问 localhost:9090就可以用配置的name和password登录spring-boot-admin的监控了.

client

client就比较简单了，

先上springBootAdmin相关依赖

<dependency>
   <groupId>org.springframework.bootgroupId>
   <artifactId>spring-boot-starter-actuatorartifactId>
dependency>

<dependency>
   <groupId>de.codecentricgroupId>
   <artifactId>spring-boot-admin-starter-clientartifactId>
dependency>

yml配置

--- # Actuator 监控端点的配置项
management:
  endpoints:
    web:
      exposure:
        include: '*'
  endpoint:
    health:
      show-details: ALWAYS
    logfile:
      external-file: /logs/xxx-xxx/sys-console.log


--- # 监控中心配置
spring.boot.admin.client:
  # 增加客户端开关
  enabled: true
  url: http://localhost:9090
  instance:
    service-host-type: IP
  #和server端的配置对应
  username: admin
  password: ccc123456

运行client后就可以在spring boot admin的管理界面看到服务注册上来了，然后就能在界面上看到日志，堆栈相关信息了
