需要新加一个Handler拦截websocket请求

com.zr.platform.websocketjava.util.regex.Patternjavax.servlet.http.HttpServletRequestjavax.servlet.http.HttpServletResponsecom.jfinal.handler.Handlercom.jfinal.kit.StrKitWebSocketHandler Handler{
    Pattern (String filterUrlRegx) {
        (StrKit.(filterUrlRegx))
            IllegalArgumentException()= Pattern.(filterUrlRegx)}
    (String targetHttpServletRequest requestHttpServletResponse response[] isHandled) {
        (.matcher(target).find())
            .handle(targetrequestresponseisHandled)}

}

在JFinal配置文件里配置 （MainConfig）

(Handlers me) {
me.add(WebSocketHandler())}

客户端页面

websocket = (in window){
                  websocket = WebSocket()}
          {
                 ()
              }

           websocket.= (){
              console.()}websocket.= (event){
                   console.()}

           websocket.= (event){
                  console.(event.data)}

          websocket.= (){
                   console.()}

           window.= (){
                   websocket.()}

           (innerHTML){
                   document.().+= innerHTML + }

          (){
                   websocket.()}

          (){
                  message = document.().valuewebsocket.(message)}
