SpringBoot+actuator和admin-UI实现监控中心

淡淡的烟草味﹌ 2024-03-17 20:04 53阅读 0赞

使用SpringBoot很久了，但是很少使用到SpringBoot的查看和监控，将来八成也不会用到，万一有机会用到呢？所以记录一下以前学习SpringBoot+actuator和adminUI实现监控中心的方式

Springboot的版本2.0.x

<parent>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-parent</artifactId>
    	<version>2.0.5.RELEASE</version>
    	<relativePath/> 
    </parent>

导入对应的包

<dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-actuator</artifactId>
    	<version>2.0.5.RELEASE</version>
    </dependency>
    
    
    
    <dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-web</artifactId>
    </dependency>

**application.properties**

server.port=7080
    
    # 配置用户名和密码
    #spring.security.user.name=admin
    #spring.security.user.password=123456
    
    # 端点信息配置
    management.server.port=8081
    management.server.servlet.context-path=/sys
    # 默认 never always可以显示硬盘使用情况和线程情况
    management.endpoint.health.show-details=always
    # 端点暴露的内容，默认["health","info"]，设置"*"代表暴露所有可访问的端点
    management.endpoints.web.exposure.include=*
    
    # actuator 信息
    info.actuator.name=test

启动之后

![myw][]  
访问

http://localhost:8081/sys/actuator

![myw][myw 1]  
在这里使用的Actuator是spring boot的一个附加功能,可帮助你在应用程序生产环境时监视和管理应用程序。可以使用HTTP的各种请求来监管,审计,收集应用的运行情况.特别对于微服务管理十分有意义.缺点：没有可视化界面。  
使用场景，针对微服务的服务状态监控，服务器的内存变化（堆内存，线程，日志管理等），检测服务配置连接地址是否可用（模拟访问，懒加载），统计现在有多少个bean(Spring容器中的bean) 统计接口数量， 应用场景：生产环境

>     /actuator/beans 显示应用程序中所有Spring bean的完整列表
>     /actuator/configprops 显示所有配置信息
>     /actuator/env 陈列所有的环境变量
>     /actuator/mappings 显示所有@RequestMapping的url整理列表
>     /actuator/health 显示应用程序运行状况信息 up表示成功 down失败，对于懒加载没报错的可以看到控制台报错了
>     /actuator/info 查看自定义应用信息

懒加载有个缺点，例如mysql的配置，启动的时候不会发现错误，只有运行的时候才报错

当访问

http://localhost:8081/sys/actuator/health

![myw][myw 2]  
使用adminUI的方式 client客户端导包和配置  
pom.xml

<dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-actuator</artifactId>
    	<version>2.0.5.RELEASE</version>
    </dependency>
    <dependency>
    	<groupId>de.codecentric</groupId>
    	<artifactId>spring-boot-admin-starter-client</artifactId>
    	<version>2.0.5</version>
    </dependency>

application.properties

server.port=8071
    
    spring.application.name=boot-example-admin-client
    
    spring.boot.admin.client.url=http://127.0.0.1:8050/myw-admin
    spring.boot.admin.client.username=admin
    spring.boot.admin.client.password=123456
    spring.boot.admin.client.instance.service-url=http://127.0.0.1:8071
    
    #management.server.port=8081
    #management.server.servlet.context-path=/sys
    # 默认 never always可以显示硬盘使用情况和线程情况
    management.endpoint.health.show-details=always
    # 端点暴露的内容，默认["health","info"]，设置"*"代表暴露所有可访问的端点
    management.endpoints.web.exposure.include=*

使用admin-ui的方式 server服务端导包和配置  
pom.xml

<dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-security</artifactId>
    </dependency>
    <dependency>
    	<groupId>de.codecentric</groupId>
    	<artifactId>spring-boot-admin-starter-server</artifactId>
    	<version>2.0.5</version>
    </dependency>

application.properties

server.port=8050
    server.servlet.context-path=/myw-admin
    spring.application.name=boot-example-admin-server
    
    spring.security.user.name=admin
    spring.security.user.password=123456

WebSecurityConfig.java

package boot.example.admin.server;
    
    import de.codecentric.boot.admin.server.config.AdminServerProperties;
    import org.springframework.security.config.annotation.web.builders.HttpSecurity;
    import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
    import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
    import org.springframework.security.web.csrf.CookieCsrfTokenRepository;
    
    /**
     * SpringBootAdmin 登录鉴权使用
     *
     */
    @EnableWebSecurity
    public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
        
    
        private final String contextPath;
    
        public WebSecurityConfig(AdminServerProperties adminServerProperties) {
        
            this.contextPath = adminServerProperties.getContextPath();
        }
    
        @Override
        protected void configure(HttpSecurity http) throws Exception {
        
            // 跨域设置，SpringBootAdmin客户端通过instances注册，见InstancesController
            http.csrf().csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())
                    .ignoringAntMatchers(contextPath + "/instances");
    
            http.authorizeRequests().antMatchers(contextPath + "/assets/**").permitAll(); // 静态资源
            http.authorizeRequests().antMatchers(contextPath + "/actuator/**").permitAll(); // 自身监控
            http.authorizeRequests().anyRequest().authenticated(); // 所有请求必须通过认证
    
            // 整合spring-boot-admin-server-ui
            http.formLogin().loginPage("/login").permitAll();
            http.logout().logoutUrl("/logout").logoutSuccessUrl("/login");
    
            // 启用basic认证，SpringBootAdmin客户端使用的是basic认证
            http.httpBasic();
        }
    }

启动客户端和服务端的监控中心

http://localhost:8050/myw-admin/login#/applications

![myw][myw 3]  
![myw][myw 4]  
![myw][myw 5]  
记录一下在SpringBoot2.6.6版本使用
