Eureka注册中心通用写法和配置

下面简单介绍下 Eureka 注册中心的通用写法
新建个空项目，pom 中加入如下依赖

<dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><version>2.5.12</version></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-server</artifactId><version>3.0.5</version></dependency><dependency><groupId>at.twinformatics</groupId><artifactId>eureka-consul-adapter</artifactId><version>1.3.0</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-security</artifactId><version>2.5.8</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-actuator</artifactId><version>2.7.18</version></dependency>
</dependencies>

新建个包路径：com.xdr630.registry.config

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {@Value("${eureka.security.enabled:false}")private boolean securityEnabled;@Overrideprotected void configure(HttpSecurity http) throws Exception {// 关闭csrf设置http.csrf().disable();if(!securityEnabled){// 配置不需要登录验证http.authorizeRequests().anyRequest().permitAll().and().logout().permitAll();return;}super.configure(http);}
}

在 com.xdr630.registry 包下，新建启动类

@EnableEurekaServer
@SpringBootApplication
public class EurekaServerApplication {private static final Logger log = LoggerFactory.getLogger(EurekaServerApplication.class);public static void main(String[] args) {SpringApplication app = new SpringApplication(EurekaServerApplication.class);app.addListeners(new ApplicationPidFileWriter(), new WebServerPortFileWriter());Environment env = app.run(args).getEnvironment();logApplicationStartup(env);}private static void logApplicationStartup(Environment env) {String protocol = "http";if (env.getProperty("server.ssl.key-store") != null) {protocol = "https";}String serverPort = env.getProperty("server.port");String contextPath = env.getProperty("server.servlet.context-path");if (StringUtils.isEmpty(contextPath)) {contextPath = "/";}String hostAddress = "localhost";try {hostAddress = InetAddress.getLocalHost().getHostAddress();} catch (UnknownHostException e) {log.warn("The host name could not be determined, using `localhost` as fallback");}// @formatter:offlog.info("\n----------------------------------------------------------\n\t" +"Application '{}' is running! Access URLs:\n\t" +"Local: \t\t{}://localhost:{}{}\n\t" +"External: \t{}://{}:{}{}\n\t" +"Profile(s): \t{}\n----------------------------------------------------------",env.getProperty("spring.application.name"),protocol,serverPort,contextPath,protocol,hostAddress,serverPort,contextPath,env.getActiveProfiles());// @formatter:on}
}

resources 下 application.yml
