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: 

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:

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}
