流口水的规则应该在周末开火吗？

Question

我正在使用drools生成警报，并且每当遇到某种情况时，我都能触发规则并生成警报。

我的要求还包括动作和烟雾警报，我们需要在平日（即周六和周日除外）制定规则。

这怎么可能？

Answer 1

您可以根据时间生成警报，也可以通过排除日期来生成警报，在这种情况下，我已经完成了一些操作。 对于这一点，你可以休耕以下步骤：

DRL文件：

import java.text.DateFormat; 
import java.text.ParseException; 
import java.text.SimpleDateFormat;

global String topicLevel 
rule "Drools Introduction" 
when 
$droolsIntro : DroolsIntroduction(topic == "Drools") 
then 
System.out.println($droolsIntro.introduceYourself() + ", topic level is " + getDefaultIfNull(topicLevel)); 
end 

rule "Drools Introduction2" 
when 
$droolsIntro : DroolsIntroduction(isTimeBetweenTwoTime("10:12:12","13:13:13","11:12:12") && isExcludeDay("000000","2016-08-08 21:5:21")) 
then 
System.out.println("time valid and sunday"); 
end 

function String getDefaultIfNull(String topicLevel) { 
return topicLevel == null ? "Moderate" : topicLevel; 
} 

function Boolean isTimeBetweenTwoTime(String initialTime, String finalTime, String currentTime) { 
     Boolean valid = false; 
     System.out.println("time check started"); 
     try { 
      if (currentTime == null) { 
       currentTime = new SimpleDateFormat("HH:mm:ss").format(Calendar.getInstance().getTime()); 
       System.out.println("check current time "+currentTime);

        currentTimecalendar3.add(Calendar.DATE, 1); 
       } 
       java.util.Date actualTime = currentTimecalendar3.getTime(); 
       if ((actualTime.after(initialTimecalendar1.getTime())

      System.out.println("exception "+valid); 
      valid=false; 
     } 
     System.out.println("finale "+valid); 
     return valid; 
    } 
    function Boolean isExcludeDay(String validdays,String timeStamp) { 
     try { 
      System.out.println("validdays"+validdays); 
      System.out.println("timeStamp"+timeStamp); 
     DateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss", Locale.ENGLISH); 
     Date date = format.parse(timeStamp); 
     Calendar currentTimecalendar3 = Calendar.getInstance(); 
     currentTimecalendar3.setTime(date); 
     int dayOfWeek = currentTimecalendar3.get(Calendar.DAY_OF_WEEK)-1; 
     Character a_char = validdays.charAt(dayOfWeek); 
     System.out.println(a_char); 
     if(a_char.compareTo('1')==0){ 
      return false; 
     }else{ 
      return true;
