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

<version>2.6.6</version>
<relativePath/> <!-- lookup parent from repository -->
