Eureka服务端搭建 eureka-server依赖导入 dependencygroupIdorg.springframework.cloud/groupIdartifactIdspring-cloud-starter-netflix-eureka-server/artifactId
/dependency启动类添加注解EnableEurekaServer EnableEurekaServer
SpringBootApplication
public class EurekaServerApplication {public static void main(String[] args) {SpringApplication.run(EurekaServerApplication.class, args);}
}配置文件application.yml配置 server:port: 8001 #指定运行端口
spring:application:name: eureka-server #指定服务名称
eureka:instance:hostname: localhost #指定主机地址client:fetch-registry: false #指定是否要从注册中心获取服务注册中心不需要开启register-with-eureka: false #指定是否要注册到注册中心注册中心不需要开启server:enable-self-preservation: false #关闭保护模式Eureka客户端搭建 eureka-client依赖导入 dependencygroupIdorg.springframework.cloud/groupIdartifactIdspring-cloud-starter-netflix-eureka-client/artifactId

SpringBootApplication
public class EurekaClientApplication {public static void main(String[] args) {SpringApplication.run(EurekaClientApplication.class, args);}
}配置文件application.yml配置 server:port: 8101 #运行端口号
spring:application:name: eureka-client #服务名称
eureka:client:register-with-eureka: true #注册到Eureka的注册中心fetch-registry: true #获取注册实例列表service-url:defaultZone: http://localhost:8001/eureka/ #配置注册中心地址Eureka集群搭建 eureka-sever添加配置文件application-replica1.yml配置第一个注册中心 server:port: 8002
spring:application:name: eureka-server
eureka:instance:hostname: replica1client:serviceUrl:defaultZone: http://replica2:8003/eureka/ #注册到另一个Eureka注册中心fetch-registry: trueregister-with-eureka: true给eureka-sever添加配置文件application-replica2.yml配置第二个注册中心 server:port: 8003
spring:application:name: eureka-server
eureka:instance:hostname: replica2client:serviceUrl:defaultZone: http://replica1:8002/eureka/ #注册到另一个Eureka注册中心fetch-registry: trueregister-with-eureka: true修改Eureka-client连接到集群 server:port: 8102

eureka:client:register-with-eureka: truefetch-registry: trueservice-url:defaultZone: http://replica1:8002/eureka/,http://replica2:8003/eureka/ #同时注册到两个注册中心Eureka添加认证 添加SpringSecurity依赖 dependencygroupIdorg.springframework.cloud/groupIdartifactIdspring-cloud-starter-netflix-eureka-server/artifactId
/dependencydependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-security/artifactId
/dependency添加application.yml配置文件配置用户名、密码 server:port: 8004
spring:application:name: eureka-security-serversecurity: #配置SpringSecurity登录用户名和密码user:name: macropassword: 123456
eureka:instance:hostname: localhostclient:fetch-registry: falseregister-with-eureka: false添加 Java 配置WebSecurityConfig 默认情况下Spring Security会开启CSRFCross-Site Request Forgery保护这是一种用于防止跨站点请求伪造攻击的安全机制。当你添加了Spring Security依赖到应用程序中时每个POST、PUT、DELETE等修改类请求都需要在请求头中包含CSRF token才能被服务器接受 默认情况下添加SpringSecurity依赖的应用每个请求都需要添加CSRF token才能访问Eureka客户端注册时并不会添加所以需要配置/eureka/**路径不需要CSRF token EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {Overrideprotected void configure(HttpSecurity http) throws Exception {http.csrf().ignoringAntMatchers(/eureka/**);super.configure(http);}
