代码铸剑:Spring Cloud Zuul服务网关实战指南
import org.springframework.cloud.netflix.zuul.filters.Route;
import org.springframework.cloud.netflix.zuul.filters.RouteLocator;
import org.springframework.cloud.netflix.zuul.web.ZuulHandlerMapping;
// 示例代码:使用ZuulHandlerMapping来定制路由
@Configuration
public class RoutingConfiguration {
@Autowired
private RouteLocator routeLocator;
@Bean
public HandlerMapping handlerMapping() {
return new ZuulHandlerMapping(routeLocator, 1);
}
@Bean
public SimpleRouteLocator routeLocator() {
return new SimpleRouteLocator(routeLocator.getPrefix(), routeLocator.getRoutes());
}
private static class SimpleRouteLocator implements RouteLocator {
private String prefix;
private List<Route> routes;
public SimpleRouteLocator(String prefix, List<Route> routes) {
this.prefix = prefix;
this.routes = routes;
}
@Override
public String getPrefix() {
return prefix;
}
@Override
public List<Route> getRoutes() {
return routes;
}
@Override
public Route getMatchingRoute(String path) {
// 实现路径匹配逻辑
// 示例:简单地返回第一个匹配的路由
for (Route route : routes) {
if (path.startsWith(route.getFullPath())) {
return route;
}
}
return null;
}
}
}
这个代码示例展示了如何自定义RouteLocator,以便在Spring Cloud Zuul服务网关中定制路由规则。这里创建了一个简单的SimpleRouteLocator
类,用于根据路径匹配逻辑返回相应的路由信息。这个例子仅为示意,实际使用时需要根据具体的路由需求来实现路径匹配逻辑。
