Question

我正在尝试为API设置Spring Cloud Gateway，但是看到路线uri出现非法参数异常。任何帮助表示赞赏。

在Ubuntu上运行此应用程序，Spring Boot 2.1.4和2.1.5都遇到了相同的例外。

这是在网关应用程序中配置我的application.properties文件的方式。

eureka.client.serviceUrl.defaultZone = http://localhost:8761/eureka
spring.application.name= api-gateway
spring.cloud.gateway.discovery.locator.enabled=true
spring.cloud.gateway.discovery.locator.lowerCaseServiceId=true
spring.cloud.gateway.routes[0].id=reporting-service
spring.cloud.gateway.routes[0].uri = lb://reporting-service
spring.cloud.gateway.routes[0].predicates[0]=Path=/api/reporting/**

这是我看到的例外。
