GatewayProperties：深入探索Spring Cloud Gateway的核心配置属性

package com.example.demo.config;
 
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.cloud.gateway.config.PropertiesRouteDefinitionLocator;
import org.springframework.context.annotation.Configuration;
 
import java.util.Map;
 
@Configuration
@ConfigurationProperties(prefix = "spring.cloud.gateway")
public class GatewayProperties {
    private Map<String, RouteDefinition> routes;
 
    public Map<String, RouteDefinition> getRoutes() {
        return routes;
    }
 
    public void setRoutes(Map<String, RouteDefinition> routes) {
        this.routes = routes;
    }
 
    public static class RouteDefinition {
        private String id;
        private URI uri;
        private int order = PropertiesRouteDefinitionLocator.DEFAULT_ORDER;
 
        // Getters and setters
    }
}

这个代码示例展示了如何在Spring Cloud Gateway中定义一个配置类，用于映射配置文件中以spring.cloud.gateway为前缀的属性。routes属性是一个映射，它将路由的名称映射到具有id、uri和order属性的RouteDefinition类的实例。这个配置类可以用于在程序启动时自动配置路由规则。
