Failed to bind properties under 'spring.cloud.gateway' to org.springframework.cloud.gateway.config.GatewayProperties:

问题springcloud getway配置文件加载失败

问题一

Description:

Failed to bind properties under 'spring.cloud.gateway' to org.springframework.cloud.gateway.config.GatewayProperties:

    Reason: HV000083: The specified annotation javax.validation.constraints.NotNull defines no attribute 'groups'.

Action:

Update your application's configuration

问题二

Failed to bind properties under 'spring.cloud.gateway.routes[0].filters[0]' to org.springframework.cloud.gateway.filter.FilterDefinition:

    Property: spring.cloud.gateway.routes[0].filters[0]
    Value: StripPrefix=1
    Origin: class path resource [application.yml]:19:15
    Reason: HV000083: The specified annotation javax.validation.constraints.NotNull defines no attribute 'groups'.

Action:

Update your application's configuration

application.yml

server:
  port: 9527

spring:
  application:
    name: getway-server
  cloud:
    gateway:
#      discovery:
#        locator:
#          enabled: true
      routes:
        - id: author-server
          uri: https://localhost:8888 #转发后的地址
          predicates:
            - Path=/author/**
          filters:
            - StripPrefix=1
#eureka:
#  client:
#    serviceUrl: #注册服务到eureka集群
#      defaultZone: http://eureka8761.com:8761/eureka,http://eureka8762.com:8762/eureka,http://eureka8763.com:8763/eureka
#  instance:
#    instance-id: ${spring.application.name}:${server.port}
#    prefer-ip-address: true     #访问路径可以显示IP地址

原因

1、配置文件名称不对
应为application.yml

2、依赖导入有问题
getway自动配置源码
GatewayAutoConfiguration.java

@Configuration(proxyBeanMethods = false)
	@ConditionalOnClass(Health.class)
	protected static class GatewayActuatorConfiguration {

		@Bean
		@ConditionalOnProperty(name = "spring.cloud.gateway.actuator.verbose.enabled",
				matchIfMissing = true)//默认为true
		@ConditionalOnAvailableEndpoint
		public GatewayControllerEndpoint gatewayControllerEndpoint(
				List<GlobalFilter> globalFilters,
				List<GatewayFilterFactory> gatewayFilters,
				List<RoutePredicateFactory> routePredicates,
				RouteDefinitionWriter routeDefinitionWriter, RouteLocator routeLocator) {
			return new GatewayControllerEndpoint(globalFilters, gatewayFilters,
					routePredicates, routeDefinitionWriter, routeLocator);
		}

		@Bean
		@Conditional(OnVerboseDisabledCondition.class)
		@ConditionalOnAvailableEndpoint
		public GatewayLegacyControllerEndpoint gatewayLegacyControllerEndpoint(
				RouteDefinitionLocator routeDefinitionLocator,
				List<GlobalFilter> globalFilters,
				List<GatewayFilterFactory> gatewayFilters,
				List<RoutePredicateFactory> routePredicates,
				RouteDefinitionWriter routeDefinitionWriter, RouteLocator routeLocator) {
			return new GatewayLegacyControllerEndpoint(routeDefinitionLocator,
					globalFilters, gatewayFilters, routePredicates, routeDefinitionWriter,
					routeLocator);
		}

	}

默认开启getway执行器配置。但没有导入相应的依赖。

pom.xml

    <dependencies>
        <!--gateway 网关依赖,内置webflux 依赖 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
        </dependency>
    </dependencies>

需导入spring-boot-starter-actuator
pom.xml

    <dependencies>
        <!--gateway 网关依赖,内置webflux 依赖 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
    </dependencies>
