【问题描述】：
我正在尝试为 api 设置 spring 云网关，但看到路由 uri 存在非法参数异常。任何帮助表示赞赏。
在 Ubuntu 上运行这个应用程序，我在 Spring boot 2.1.4 和 2.1.5 中都遇到了同样的异常。
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。

这就是问题
-
感谢您的帮助，但在进行更改后，我的构建失败并出现此错误。应用程序启动失败说明：绑定到目标 [Bindable@330c1f61 type = java.util.List
, value = 'provided', annotations = array [@ javax.validation.constraints.NotEmpty(message={javax.validation.constraints.NotEmpty.message}, groups=[], payload=[]), @javax.validation.Valid()]] 失败：属性：spring.cloud .gateway.routes[0].predicates[0].path 值：/api/reporting/** -
这是我在错误消息中看到的。原因：org.springframework.boot.context.properties.bind.BindException：无法将 'spring.cloud.gateway.routes[0].predicates' 下的属性绑定到 java.util.List
原因：org.springframework.boot.context.properties.bind.UnboundConfigurationPropertiesException：元素 [spring.cloud.gateway.routes[0].predicates[0].path] 未绑定。 -
我错了，改成这个
spring.cloud.gateway.routes[0].predicates=Path=/api/reporting/**
