SpringBoot+actuator和admin-UI实现监控中心方式
作者:蚂蚁舞
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/> <!-- lookup parent from repository --> </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> <!-- security 一旦导入就会生效 --> <!-- <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-test</artifactId> <scope>test</scope> </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
访问
http://localhost:8081/sys/actuator
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
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
记录一下在SpringBoot2.6.6版本使用
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.6.6</version> <relativePath/> <!-- lookup parent from repository --> </parent>
client的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>2.6.6</version> </dependency> <dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-starter-client</artifactId> <version>2.5.6</version> </dependency>
application.properties 1
server.port=8071 spring.application.name=boot-example-admin-client1 spring.boot.admin.client.url=http://localhost:8050 spring.boot.admin.client.username=admin spring.boot.admin.client.password=123456 management.endpoint.health.show-details=always management.endpoints.web.exposure.include=*
application.properties 2
server.port=8072 spring.application.name=boot-example-admin-client2 spring.boot.admin.client.url=http://localhost:8050 spring.boot.admin.client.username=admin spring.boot.admin.client.password=123456 management.server.port=8082 management.server.base-path = /sys management.endpoint.health.show-details=always management.endpoints.web.exposure.include=*
application.properties 3
server.port=8073 spring.application.name=boot-example-admin-client3 spring.boot.admin.client.url=http://localhost:8050 spring.boot.admin.client.username=admin spring.boot.admin.client.password=123456 #spring.security.user.name=admin #spring.security.user.password=123456 management.server.port=8083 management.server.base-path = /sys management.endpoint.health.show-details=always management.endpoints.web.exposure.include=*
服务端的配置
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>2.5.6</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency>
application.properties
server.port=8050 spring.application.name=boot-example-admin-server spring.security.user.name=admin spring.security.user.password=123456
总结
备注记录到这里 将来会不会用到再说了。
以上为个人经验,希望能给大家一个参考,也希望大家多多支持脚本之家。
