配置Admin Server
既然是管理程序,肯定有一個server,配置server很簡單,我們添加這個依賴即可:
<dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-starter-server</artifactId> <version>2.2.2</version></dependency>
同時我們需要在main程序中添加@EnableAdminServer來啟動admin server。
@EnableAdminServer@SpringBootApplicationpublic class SpringBootAdminServerApplication { public static void main(String[] args) { SpringApplication.run(SpringBootAdminServerApplication.class, args); }}
配置admin client
有了server,我們接下來配置需要監控的client應用程序,在本文中,我們自己監控自己,添加client依賴如下:
<dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-starter-client</artifactId> <version>2.2.2</version></dependency>
我們需要為client指定要注冊到的admin server:
spring.boot.admin.client.url=http://localhost:8080
因為Spring Boot Admin依賴于 Spring Boot Actuator, 從Spring Boot2 之后,我們需要主動開啟暴露的主鍵,如下:
management.endpoints.web.exposure.include=*management.endpoint.health.show-details=always
配置安全主鍵
通常來說,我們需要一個登陸界面,以防止未經授權的人訪問。spring boot admin提供了一個UI供我們使用,同時我們添加Spring Security依賴:
<dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-server-ui-login</artifactId> <version>1.5.7</version></dependency><dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId></dependency>
添加了Spring Security,我們需要自定義一些配置:
@Configurationpublic class WebSecurityConfig extends WebSecurityConfigurerAdapter { private final AdminServerProperties adminServer; public WebSecurityConfig(AdminServerProperties adminServer) { this.adminServer = adminServer; } @Override protected void configure(HttpSecurity http) throws Exception { SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler(); successHandler.setTargetUrlParameter("redirectTo"); successHandler.setDefaultTargetUrl(this.adminServer.getContextPath() + "/"); http .authorizeRequests() .antMatchers(this.adminServer.getContextPath() + "/assets/**").permitAll() .antMatchers(this.adminServer.getContextPath() + "/login").permitAll() .anyRequest().authenticated() .and() .formLogin() .loginPage(this.adminServer.getContextPath() + "/login") .successHandler(successHandler) .and() .logout() .logoutUrl(this.adminServer.getContextPath() + "/logout") .and() .httpBasic() .and() .csrf() .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse()) .ignoringRequestMatchers( new AntPathRequestMatcher(this.adminServer.getContextPath() + "/instances", HttpMethod.POST.toString()), new AntPathRequestMatcher(this.adminServer.getContextPath() + "/instances/*", HttpMethod.DELETE.toString()), new AntPathRequestMatcher(this.adminServer.getContextPath() + "/actuator/**")) .and() .rememberMe() .key(UUID.randomUUID().toString()) .tokenValiditySeconds(1209600); }}
接下來,我們在配置文件中指定服務器的用戶名和密碼:
spring.boot.admin.client.username=adminspring.boot.admin.client.password=admin
作為一個客戶端,連接服務器的時候,我們也需要提供相應的認證信息如下:
spring.boot.admin.client.instance.metadata.user.name=adminspring.boot.admin.client.instance.metadata.user.password=adminspring.boot.admin.client.username=adminspring.boot.admin.client.password=admin
好了,登錄頁面和權限認證也完成了。
Hazelcast集群
Spring Boot Admin 支持Hazelcast的集群,我們先添加依賴如下:
<dependency> <groupId>com.hazelcast</groupId> <artifactId>hazelcast</artifactId> <version>3.12.2</version></dependency>
然后添加Hazelcast的配置:
@Configurationpublic class HazelcastConfig { @Bean public Config hazelcast() { MapConfig eventStoreMap = new MapConfig("spring-boot-admin-event-store") .setInMemoryFormat(InMemoryFormat.OBJECT) .setBackupCount(1) .setEvictionPolicy(EvictionPolicy.NONE) .setMergePolicyConfig(new MergePolicyConfig(PutIfAbsentMapMergePolicy.class.getName(), 100)); MapConfig sentNotificationsMap = new MapConfig("spring-boot-admin-application-store") .setInMemoryFormat(InMemoryFormat.OBJECT) .setBackupCount(1) .setEvictionPolicy(EvictionPolicy.LRU) .setMergePolicyConfig(new MergePolicyConfig(PutIfAbsentMapMergePolicy.class.getName(), 100)); Config config = new Config(); config.addMapConfig(eventStoreMap); config.addMapConfig(sentNotificationsMap); config.setProperty("hazelcast.jmx", "true"); config.getNetworkConfig() .getJoin() .getMulticastConfig() .setEnabled(false); TcpIpConfig tcpIpConfig = config.getNetworkConfig() .getJoin() .getTcpIpConfig(); tcpIpConfig.setEnabled(true); tcpIpConfig.setMembers(Collections.singletonList("127.0.0.1")); return config; }}
