没有“org.springframework.cloud.gateway.filter.factory.TokenRelayGatewayFilterFactory”类型的合格bean

Question

我正在尝试使用

实现过滤器

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.gateway.filter.factory.TokenRelayGatewayFilterFactory;
import org.springframework.cloud.gateway.route.RouteLocator;
import org.springframework.cloud.gateway.route.builder.RouteLocatorBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class SecurityConfig {

    private TokenRelayGatewayFilterFactory filterFactory;

    @Autowired
    public SecurityConfig(TokenRelayGatewayFilterFactory filterFactory) {
        this.filterFactory = filterFactory;
    }

    @Bean
    public RouteLocator customRouteLocator(RouteLocatorBuilder builder) {
        return builder.routes()
                .route("resource", r -> r.path("/resource")
                        .filters(f -> f.filters(filterFactory.apply())
                                .removeRequestHeader("Cookie"))
                        .uri("http://resource:9000"))
                .build();
    }
}

我使用 Spring Cloud 版本2021.0.0 和本教程：https://spring.io/blog/2019/08/16/securing-services-with-spring-cloud-gateway

你知道我该如何解决这个问题吗？

附言

plugins {
    id 'org.springframework.boot' version '2.6.3'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group = 'com.test.gateway'
version = '0.0.1'
sourceCompatibility = '17'

repositories {
    mavenCentral()
}

ext {
    set('springCloudVersion', "2021.0.0")
}

dependencies {
    implementation group: 'org.springframework.cloud', name: 'spring-cloud-starter-gateway'
    implementation 'com.netflix.eureka:eureka-core'
    implementation 'org.springframework.cloud:spring-cloud-starter-netflix-eureka-client'
    implementation 'org.springframework.boot:spring-boot-starter-actuator'
}

dependencyManagement {
    imports {
        mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
    }
}

test {
    useJUnitPlatform()
}

Description:

Parameter 0 of constructor in org.gateway.security.SecurityConfig required a bean of type 'org.springframework.cloud.gateway.filter.factory.TokenRelayGatewayFilterFactory' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.cloud.gateway.filter.factory.TokenRelayGatewayFilterFactory' in your configuration.

Answer 1

这里有两件事需要验证：

1. TokenRelayGatewayFilterFactory 应该是@component/@service/@repository。
2. 如果是，则 spring 无法在路径中找到它。因此，您需要使用 @ComponentScan() 来指定它必须搜索哪些 basePackage，您将能够克服这个问题。
