SpringBootAdmin用來管理和監控SpringBoot應用程序,它利用spring-boot-starter-actuator提供的功能,將各個微服務的狀態整合到一起,並提供良好的界面查看支持,並且能夠動態的修改實例日志級別。SpringBootAdmin分為server端和client端,server端可查看各個微服務的狀態,client端將微服務注冊到server端。github源碼地址:https://github.com/codecentric/spring-boot-admin
1、服務端基本配置
1)pom.xml依賴
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-server</artifactId> <version>2.2.1</version> </dependency> <dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-server-ui</artifactId> <version>2.2.1</version> </dependency>
2)application.properties配置
server.port=8001 spring.application.name=admin-server
3)SpringBoot啟動類添加@EnableAdminServer注解
@EnableAdminServer @SpringBootApplication public class AdminServerApplication { public static void main(String[] args) { SpringApplication.run(AdminServerApplication.class, args); } }
2、客戶端基本配置
1)pom.xml依賴
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-starter-client</artifactId> <version>2.2.1</version> </dependency>
2)application.properties配置
server.port=8002 spring.application.name=admin-client spring.boot.admin.client.url=http://127.0.0.1:8001 management.endpoints.web.exposure.include=* management.endpoint.health.show-details=ALWAYS
3)客戶端不需要做任何代碼修改
3、查看SpringBootAdmin效果
1)啟動服務端和客戶端后,訪問http://127.0.0.1:8001,就可以查看所有注冊的實例
2)點擊具體實例就可以查看到當前實例的具體運行狀態,在該界面可查看應用實例的健康狀態、線程、內存使用、GC時間
3)修改日志級別。點擊日志配置,根據包過濾需要修改的類,將level由info調整到debug后,該實例對應的代碼就可以輸出debug級別的日志了。
4、啟用認證
SpringBootAdmin的認證系統由spring-security管理。
1)服務端pom.xml文件增加spring-security依賴,改為:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-server</artifactId> <version>2.2.1</version> </dependency> <dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-server-ui</artifactId> <version>2.2.1</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency>
2)服務端application.properties增加security用戶和密碼配置信息,修改為:
server.port=8001 spring.application.name=admin-server spring.security.user.name=admin spring.security.user.password=abc123
3)服務端增加Java代碼,配置spring-security
package com.zhi.demo.config; 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.csrf.CookieCsrfTokenRepository; import de.codecentric.boot.admin.server.config.AdminServerProperties; /** * 配置security驗證頁面指向SpringBootAdmin提供的UI界面 * * @author zhi.leaf * @since 2020年1月20日17:44:25 * */ @Configuration public class SecuritySecureConfig extends WebSecurityConfigurerAdapter { private final String contextPath; public SecuritySecureConfig(AdminServerProperties adminServerProperties) { this.contextPath = adminServerProperties.getContextPath(); } @Override protected void configure(HttpSecurity http) throws Exception { // 跨域設置,SpringBootAdmin客戶端通過instances注冊,見InstancesController http.csrf().csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse()) .ignoringAntMatchers(contextPath + "/instances"); http.authorizeRequests().antMatchers(contextPath + "/assets/**").permitAll(); // 靜態資源 http.authorizeRequests().anyRequest().authenticated(); // 所有請求必須通過認證 // 整合spring-boot-admin-server-ui http.formLogin().loginPage("/login").permitAll(); http.logout().logoutUrl("/logout").logoutSuccessUrl("/login"); // 啟用basic認證,SpringBootAdmin客戶端使用的是basic認證 http.httpBasic(); } }
4)客戶端application.properties也增加用戶和密碼信息,和服務端保持一致,改為
server.port=8002 spring.application.name=admin-client spring.boot.admin.client.url=http://127.0.0.1:8001 spring.boot.admin.client.username=admin spring.boot.admin.client.password=abc123
5)重啟服務端和客戶端后,http://127.0.0.1:8001/,將會出現登錄界面
5、通知提醒。SpringBootAdmin提供了多種通知功能,也可以自定義通知提醒。這里我們驗證一下郵件通知功能
1)服務端poxm.xml增加配置
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency>
2)增加配置
spring.mail.host=smtp.qq.com spring.mail.username=xxxx@foxmail.com spring.mail.password=xxxx spring.boot.admin.notify.mail.from=xxxx@foxmail.com spring.boot.admin.notify.mail.to=yyyy@foxmail.com
3)當客戶端實例停掉后,我們會受到如下郵件提醒,郵件模板是可以配置的。
