篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Java 设定工作日日历相关的知识，希望对你有一定的参考价值。

开发清单

JDK 1.7

Servlet 3.0

Dom4j 1.6.1

FullCanlendar 3

后台考虑兼容性，并没有使用数据库，而是采用xml格式存储数据，毕竟一年只有365天，点击FullCanlendar的某一天，设置为休息日，再次点击取消。

整个项目只使用了一个index.html作为展示界面。

具体代码为：

服务端使用Java Servlet处理。功能包括，【初始化日历】，【清空日历】，【点击日历增加休息日标签】，【点击标签移除标签】。

两点功能，采用dom4j为数据源，采用纯Java Servlet，目的是为了在任何Java Web项目当中都可以使用，前端日历框架使用了FullCalendar与BootStrpa模态效果。

首先粘贴Servlet代码，从XML中获取数据，代码如下：

package com.yu.wday;

import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.dom4j.Attribute;
import org.dom4j.Document;
import org.dom4j.Element;

import com.yu.wday.util.Dom4JUtil;
import com.yu.wday.util.ResponseSendJson;

/**
 * qq80303857
 * Servlet implementation class FullCanlendarServlet
 */
@WebServlet("/FullCanlendarServlet")
public class FullCanlendarServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;
       
    /**
     * @see HttpServlet#HttpServlet()
     */
    public FullCanlendarServlet() {
        super();
        // TODO Auto-generated constructor stub
    }

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    @SuppressWarnings({ "unused", "unchecked" })
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        String path = request.getServletContext().getRealPath("/");
        File file = new File(path+"FullCanlendar/note.xml");
        Document document = Dom4JUtil.parse(file);
        Element root = document.getRootElement();
        
        List<Element> list = root.elements("event");
        
        String json = Dom4JUtil.XML2Json(list);
        
        ResponseSendJson.sendJson(response, json);
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        doGet(request, response);
    }

}

点击日历增加休息日标签与点击休息日标签删除标签分别使用了GET与POST区分，Servlet代码如下：

package com.yu.wday;

import java.io.File;
import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

        for (Element ele:list){
            parentElement.remove(ele);
        }
    }
}

检查休息日，代码如下：

package com.yu.wday.util;

import java.util.Calendar;

public class DateUtils {

    
    /**  
      *   
      * <p>Title: checkHoliday </P>  
      * <p>Description: TODO 验证日期是否是节假日</P>  
      * @param calendar  传入需要验证的日期  
      * @return   
      * return boolean    返回类型  返回true是节假日，返回false不是节假日  
      * throws   
      * date 2014-11-24 上午10:13:07  
      */  
     public static boolean checkHoliday(Calendar calendar){  
           
         //判断日期是否是周六周日  
         if(calendar.get(Calendar.DAY_OF_WEEK) == Calendar.SUNDAY ||   
                 calendar.get(Calendar.DAY_OF_WEEK) == Calendar.SATURDAY){  
             return true;  
         }    
         return false;  
     }
}

常用工具栏，判断字符串是否可以转换为数字，代码如下：

package com.yu.wday.util;

public class EveryDayUtils {

    public static boolean strIsNum(String str){
        try {
            Integer.valueOf(str);//把字符串强制转换为数字
            return true;//如果是数字，返回True
        } catch (Exception e) {
            return false;//如果抛出异常，返回False
        }
    }
    
}

使用Response发送Json数据，代码如下：

package com.yu.wday.util;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.http.HttpServletResponse;

public class ResponseSendJson {

    
    public static void sendJson(HttpServletResponse response,String json){
        
        response.setCharacterEncoding("UTF-8");  
        response.setContentType("application/json; charset=utf-8");  

        PrintWriter out = null;
        try {
            out = response.getWriter();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        out.append(json);
        out.flush();
        out.close();
    }
}

有了这些数据，就很轻而易举的判断哪天是休息日咯。
