Eureka安全认证

Eureka 服务加入安全认证只需要在之前的服务中增加三处步骤即可：

1、在Eureka Server中加入spring-boot-starter-security依赖

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

注意：只要加入了security包则自动开启了默认安全认证，密码随机生成，在控制台可以看到。

2、修改application.yml新增配置

spring:
  application:
    name: mima-cloud-eureka
server:
  port: 8761
security:
  basic:
    #关闭安全验证
    enabled: true
  user:
    name: ruthless
    password: 123456
eureka: 
  instance:
    #实例主机名
    hostname: localhost
  client:
    #不向Eureka注册自己
    register-with-eureka: false
    #不检查其他的EurekaServer节点
    fetch-registry: false

3、启动Eureka服务：

输入配置文件中配置的用户名和密码即可。

4、在Eureka Client中修改application.yml中的service-url，形式为下面的模式:
eureka.client.serviceUrl.defaultZone=http://${userName}:${password}@localhost:1111/eureka/

debug: false
spring:
  application:
    name: mima-cloud-eureka-producer
server:
  port: 9907
eureka:
  client: 
    serviceUrl: 
      #defaultZone: http://localhost:8761/eureka/
      defaultZone: http://ruthless:123456@localhost:8761/eureka/
  instance:
    prefer-ip-address: true
    instance-id: ${spring.application.name}:${spring.cloud.client.ipAddress}:${server.port}
