spring.cloud.gateway.routes[1].id=business
spring.cloud.gateway.routes[1].uri=lb://business
spring.cloud.gateway.routes[1].predicates[0].name=Path
spring.cloud.gateway.routes[1].predicates[0].args[0]=/business/**

我把spring.cloud.gateway.routes[1].uri的值从http://127.0.0.1:9002改为了lb://business之后，就报错了:

是访问接口时报的。

老师，帮我看看吧。谢谢。
