在配置zuul的时候，用postman调接口的时候报错误：

在stackoverflow和github上找了很多办法，但是还不能解决我的问题，可能对你有用，一并总结如下：

1.  https://stackoverflow.com/questions/41401009/load-balancer-does-not-have-available-server-for-client
2.  https://github.com/spring-cloud/spring-cloud-netflix/issues/2530

这些都解决不了问题，后来查了zuul的官方配置：https://cloud.spring.io/spring-cloud-netflix/multi/multi\_\_router\_and\_filter\_zuul.html

发现我的zuul中boostrap.properties的配置是：  
zuul.routes.user-service-1.path=/*/\*\*  
zuul.routes.user-service-2.path=/*/\*\*  
如果把user-service-2这个配置去掉，那么就正常，一旦加上就报错，后来怀疑是/\*/**是这个地方配置有问题，但是改成：  
zuul.routes.user-service-1.path=/user-service-1/**  
zuul.routes.user-service-2.path=/user-service-2/\*\*  
用postman调接口的时候，就要重复用user-service-1, 例如：  
get http://localhost:8900/user-service-1/user-service-1/user  
这样才调得通，但是很显然这不是想要的，应该是：  
get http://localhost:8900/user-service-1/user

于是查看zuul的配置文档，找到:  
![这里写图片描述][70]

于是配置：  
zuul.routes.user-service-1.path=/user-service-1/\*\*  
zuul.routes.user-service-1.stripPrefix=false  
zuul.routes.user-service-2.path=/user-service-1/\*\*  
zuul.routes.user-service-2.stripPrefix=false
