老生常谈的配置但是还是需要说明一下

EurekaApplication

@EnableEurekaServer指定为server端

@EnableEurekaServer
@SpringBootApplication
public class EurekaApplication {
 
 public static void main(String[] args) {
  SpringApplication.run(EurekaApplication.class, args);
 }
 
}

WebSecurityConfig

看到这眼熟不呢没错 Eureka也开启spring security 在访问前台页面时也需要输入账号密码

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
 
 @Override
 protected void configure(HttpSecurity http) throws Exception {
  super.configure(http);
  http.csrf().disable().httpBasic();
 }
}

application.yml

security:user以下配置的账号密码在访问页面需要输入的

server:
 port: 7001
spring:
 application:
 name: eureka
 security:
 user:
  name: admin
  password: xxxxxxxxxx
eureka:
 client:
 fetch-registry: false
 register-with-eureka: false
 service-url:
  defaultZone: http://admin:Xk38CNHigBP5jK75@localhost:5001/eureka
 instance:
 hostname: localhost
 prefer-ip-address: true
logging:
 config: classpath:logback.xml
 level:
 root: info

pom.xml

 <dependencies>
  <dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-security</artifactId>

  <dependency>

  </dependency>
  <dependency>
   <groupId>org.springframework.security</groupId>
   <artifactId>spring-security-test</artifactId>
   <scope>test</scope>
  </dependency>
 </dependencies>

当访问localhost:7001 出现下图需要填写账号密码

在其他服务注册时也需要指定账号密码

eureka:
 instance:
 hostname: ${spring.cloud.client.ip-address}
 prefer-ip-address: true
 instance-id: ${eureka.instance.hostname}:${server.port}
 //与server一致
 client:
 security:
  basic:
  user: admin
  password: xxxxxxxxxxx
 service-url:
  defaultZone: http://${eureka.client.security.basic.user}:${eureka.client.security.basic.password}@localhost:7001/eureka
