解析spring cloud ouath2中的Eureka

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

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
