Spring Cloud Gateway -找不到名为[Filter_Name]的GatewayFilterFactory

Question

我有一个spring云网关应用程序。我正在尝试设置网关筛选器。Spring Boot版本是2.3.4.RELEASE，下面是依赖项：

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter'
    implementation platform(SpringBootPlugin.BOM_COORDINATES)
    implementation platform('org.springframework.cloud:spring-cloud-dependencies:Hoxton.SR8')
    implementation 'org.springframework.boot:spring-boot-starter-actuator'
    implementation 'org.springframework.cloud:spring-cloud-starter-gateway'
    implementation 'org.springframework.cloud:spring-cloud-starter-sleuth'
    implementation 'org.springframework.cloud:spring-cloud-starter-netflix-eureka-client'

}

以下是网关客户端的配置

server:
  port: 8081
spring:
  cloud:
    gateway:
      routes:
        - id: onboard_redirect
          uri: http://localhost:8080/api/v1/onboard
          predicates:
            - Path=/api/v1/onboard
          filters:
            - name: MyLogging
              args:
                baseMessage: My Custom Message
                preLogger: true
                postLogger: true

下面是我的filter类：

@Component
public class MyLoggingGatewayFilterFactory extends AbstractGatewayFilterFactory<MyLoggingGatewayFilterFactory.Config> {

    final Logger logger =
            LoggerFactory.getLogger(MyLoggingGatewayFilterFactory.class);

    public MyLoggingGatewayFilterFactory() {
        super(Config.class);
    }

    @Override
    public GatewayFilter apply(Config config) {
        return (exchange, chain) -> {
            // Pre-processing
            if (config.preLogger) {
                logger.info("Pre GatewayFilter logging: "
                        + config.baseMessage);
            }
            return chain.filter(exchange)
                    .then(Mono.fromRunnable(() -> {
                        // Post-processing
                        if (config.postLogger) {
                            logger.info("Post GatewayFilter logging: "
                                    + config.baseMessage);
                        }
                    }));
        };
    }

    public static class Config {
        public String baseMessage;
        public boolean preLogger;
        public boolean postLogger;
    }
}

在没有配置过滤器的情况下，一切都可以正常工作，但是当我配置过滤器时，我得到了以下错误：

reactor.core.Exceptions$ErrorCallbackNotImplemented: java.lang.IllegalArgumentException: Unable to find GatewayFilterFactory with name MyLogging
Caused by: java.lang.IllegalArgumentException: Unable to find GatewayFilterFactory with name MyLogging

我在这里做错了什么？

Answer 1

过滤器类是MyLoggingGatewayFilterFactory，而不是您在属性中设置的MyLogging。

尝试在您的application.yml文件中进行以下修改：

filters:
    - name: MyLoggingGatewayFilterFactory

Answer 2

在application.properties文件中添加此依赖项。

<dependency>
       <groupId>org.springframework.cloud</groupId>
       <artifactId>spring-cloud-starter-circuitbreaker-reactor- 
     resilience4j</artifactId>
</dependency>
