在配置Zuul时遇到一个问题，使用Postman调用接口时收到'Forwarding error: Load balancer does not have available server for client'的错误。尝试了StackOverflow和GitHub上的解决方案但未成功。问题出在Zuul的bootstrap.properties配置，最初配置为`zuul.routes.user-service-1.path=/**`和`zuul.routes.user-service-2.path=/**`。移除其中一个配置后问题暂时解决，但不是理想的解决方案。经过研究，将路径改为`/user-service-1/**`和`/user-service-2/**`，同时设置`stripPrefix=false`，解决了路径匹配的问题，现在可以正确调用如'http://localhost:8900/user-service-1/user'的接口。
