开发清单
- JDK 1.7
- Servlet 3.0
- JSP
- 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。
XML格式为：
<?xml version="1.0" encoding="UTF-8"?>
<roots xmlns="http://www.phpStudy.net" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.phpStudy.net note.xsd">

<event ID="S2016-12-04" start="2016-12-04" title="休息日"/>
<event ID="S2016-12-03" start="2016-12-03" title="休息日"/>

<event ID="S2017-01-01" start="2017-01-01" title="休息日"/>
</roots>约束文档为：

</html>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 javax.servlet.ServletException;

import org.dom4j.Element;
import com.yu.wday.util.Dom4JUtil;
import com.yu.wday.util.ResponseSendJson;
/**

public class FullCanlendarSaveTag extends HttpServlet {
private static final long serialVersionUID = 1L;
/**

super();
// TODO Auto-generated constructor stub
}
/**

*/
@SuppressWarnings("unused")
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String path = request.getServletContext().getRealPath("/");
String start = request.getParameter("start");
String title = request.getParameter("title");
if (title!=null){
title = new String(title.getBytes("ISO-8859-1"),"UTF-8");
}else{
title = "休息日";
}
File file = new File(path+"FullCanlendar/note.xml");
Document document = Dom4JUtil.parse(file);
Element root = document.getRootElement();
Element element = root.elementByID("S"+start);
if (element!=null){
ResponseSendJson.sendJson(response, "{\"success\":\"exist\"}");
}else{
Element curEle = root.addElement("event");
curEle.addAttribute("ID", "S"+start);
curEle.addAttribute("start", start);
curEle.addAttribute("title", title);
Dom4JUtil.write(file, document);
ResponseSendJson.sendJson(response, "{\"success\":\"sav\"}");
}
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String path = request.getServletContext().getRealPath("/");
String id = request.getParameter("id");
File file = new File(path+"FullCanlendar/note.xml");
Document document = Dom4JUtil.parse(file);
Element root = document.getRootElement();
Element element = root.elementByID(id);
if (element!=null){
root.remove(element);
Dom4JUtil.write(file, document);
ResponseSendJson.sendJson(response, "{\"success\":\"del\"}");
}else{
root.remove(element);
Dom4JUtil.write(file, document);
ResponseSendJson.sendJson(response, "{\"success\":\"exist\"}");
}
}
}
初始化休息日与清空所有标签，分别使用GET与POST区分，Servlet代码如下：
package com.yu.wday;

File file = new File(path+"FullCanlendar/note.xml");
Document document = Dom4JUtil.parse(file);

Dom4JUtil.clear(root, root.elements("event"));

String parmYear = request.getParameter("year");

public static void clear (Element parentElement,List<Element> list){

}
}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。
