Eureka的实操
2、安全连接方式
Eureka的安全连接可以通过以下步骤实现：
- 添加依赖：在项目的pom.xml文件中添加Eureka的依赖。
- 配置安全连接：在项目的application.yml或application.properties文件中添加Eureka的安全连接配置。具体包括设置安全基础URL、客户端ID、客户端密钥等。
- 关闭跨域攻击：在服务端增加配置类，关闭防止跨域攻击。如果需要跨域，可以在配置类中添加允许跨域的注解。
- 启用认证：在客户端项目中添加安全配置，设置账号密码，并启用Eureka的安全连接。
完成以上步骤后，即可实现Eureka的安全连接。注意，具体的配置方式可能因项目需求和环境而有所不同，需要结合实际情况进行调整。
