腌萝卜皮springcloudgateway⾃定义断⾔规则，以后缀结尾进⾏路由
因⼯作需要，需要使⽤springcloud gateway ，以.html结尾的进⾏路由进⾏websocket转发。gateway⾃带的8种路由规则都不能满⾜，故需要⾃定义断⾔规则。
⼀，新建⼀个路由断⾔⼯⼚ExtCheckRoutePredicateFactory
@Component
public class ExtCheckRoutePredicateFactory extends AbstractRoutePredicateFactory<ExtCheckRoutePredicateFactory.Config> {
public ExtCheckRoutePredicateFactory() {
super(Config.class);

public Predicate<ServerWebExchange> apply(Config config) {
return new Predicate<ServerWebExchange>() {
@Override
public boolean test(ServerWebExchange rverWebExchange) {
String Request().getURI().toString();
dsWith(".html")){
return true;
}
return fal;
}
};
}
public static class Config{
private String name;
public String getName(){
return name;

}
public void tName(String name){
this.name=name;
}
}
}
如果以.html结尾，则匹配此路由
⼆，修改gateway配置
gateway:
普通话手抄报内容
routes:
- id: abc
uri: localhost:8080
predicates:
- name: ExtCheck
ExtCheck即是我们新建断⾔⼯⼚的前缀名，⾃动识别的。
这时运⾏发现，系统根本找不到我们⾃定义的断⾔类。
需要第三步
三，修改gateway源码，将⾃定义断⾔类加到系统 predicates⾥

@Bean
public RouteLocator routeDefinitionRouteLocator(GatewayProperties properties, List<GatewayFilterFactory> gatewayFilters,
List<RoutePredicateFactory> predicates,

ConfigurationService configurationService) {
predicates.add(new ExtCheckRoutePredicateFactory());
return new RouteDefinitionRouteLocator(routeDefinitionLocator, predicates,
gatewayFilters, properties, configurationService);
}
再次运⾏，成功根据.html后缀转发，done!
