JavaSpring云网关重定向

Question

我有一个简单的要求，就是用新的uri替换旧的uri，这样客户机仍然可以调用旧的uri

我的API网关在端口8090上运行，它连接到Eureka服务器

这是网关中的属性文件

spring.application.name=api-gateway-server
server.port=8090
eureka.client.serviceUrl.defaultZone=http://localhost:9100/eureka

spring.cloud.gateway.discovery.locator.enabled=true

spring.cloud.gateway.discovery.locator.lower-case-service-id=true

logging.level.root=DEBUG

通过网关的旧API是

http://localhost:8090/currency-conversion-service/currency-convertor-feign/from/USD/to/INR/456

其中，“货币兑换服务”是Eureka中目标应用程序的名称

货币转换服务应用程序中的URI已更改为

/currency-convertor-v2/from/USD/to/INR/456

从

/currency-convertor-feign/from/USD/to/INR/456

所以我想要的是当客户端点击API网关URL时

http://localhost:8090/currency-conversion-service/currency-convertor-feign/from/USD/to/INR/456

请求被重定向到

/currency-convertor-v2/from/USD/to/INR/456

在货币兑换服务中

这是我试图在网关应用程序中编写的代码

package com.kingshuk.springcloudprojects.apigatewayserver;

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 ApiRoutingConfiguration {

    @Bean
    public RouteLocator applicationRouteLocator(RouteLocatorBuilder builder) {
        return builder.routes()
                .route(p -> p.path("/currency-convertor-feign/**")
                        .filters(gatewayFilterSpec -> gatewayFilterSpec
                                .rewritePath("/currency-convertor-feign/(?<remaining>.*)"
                                , "/currency-convertor-v2/${remaining}}"))
                        .uri("http://currency-conversion-service/"))
                .build();
    }
}

但它不起作用。不断地出错。API网关日志中不会打印任何异常

我对SpringCloudGateway有点陌生，所以如果我能在这方面得到一些帮助，那就太好了

谢谢

更新：

它现在可以根据spencergibb的建议进行以下代码调整。感谢你的帮助

@Bean
    public RouteLocator applicationRouteLocator(RouteLocatorBuilder builder) {
        return builder.routes()
                .route(p -> p.path("/currency-conversion-service/currency-convertor-feign/**")
                        .filters(gatewayFilterSpec -> gatewayFilterSpec
                                .rewritePath("/currency-conversion-service/currency-convertor-feign/(?<remaining>.*)"
                                , "/currency-convertor-v2/${remaining}"))
                        .uri("lb://currency-conversion-service/"))
                .build();
    }
