作者:互联网

@Override
	public String downloadTeachClassTemplate() {
		HSSFWorkbook work = null;
		List<KeyValueBean> headList = new ArrayList<KeyValueBean>(); 
		String[] headerList = new String[]{"课程编号!","课程名称","班级名称!","教师工号!","教师名称","理论周学时","实训周学时","实训场地","连排节数!"}; 
		String[] explainList = new String[]{"说明:必填,填入系统中已经存在的课程编号",
				"说明:选填,该列可以不填,导入表格时以课程号为准",
				"说明:必填,填入系统中存在的班级名称,多个班级间以“,”分隔(例:班1,班2)",
				"说明:必填,填入系统为教工用户分配的系统工号",
				"说明:选填,可以填入该工号对应的教师名称,导入时以教师工号为准",
				"说明:选填,只能填写大于或等于0的整数,如果不填默认为0",
				"说明:选填,只能填写大于或等于0的整数,如果不填默认为0",
				"说明:选填,填写实训教室的名称,多个实训场地以“,”分隔",
				"说明:选填,填写连排节数,默认连排节数为1"						
		}; 
		for (int i = 0; i < headerList.length; i++) {
			headList.add(new KeyValueBean(headerList[i],explainList[i]));
		}
		work = Utils.genericSheet("导入排课教学计划", headList, null, work);
		work = courseSheet(work);
		return Utils.writeToWork(work, "teachClassTemplate.xls");
	}
	public HSSFWorkbook courseSheet(HSSFWorkbook work) {
		List<KeyValueBean> headList = new ArrayList<KeyValueBean>(); 
		List<Map<String,Object>> data = new ArrayList<Map<String,Object>>();
		String[] headerList = new String[]{"课程编号","课程名称"}; 
		String[] explainList = new String[]{"说明:对应系统课程编号","说明:课程编号对应的课程名称"}; 
		for (int i = 0; i < headerList.length; i++) {
			headList.add(new KeyValueBean(headerList[i],explainList[i]));
		}
		List<ZhxyInfoCourseVO> courseList = zhxyInfoCourseDAO.getAllInfoCourse(null);
		if(CollectionUtils.isNotEmpty(courseList)){
			for (ZhxyInfoCourseVO zhxyInfoCourseVO : courseList) {
		    	Map<String,Object> map = new HashMap<String, Object>();
		    	map.put(headerList[0], zhxyInfoCourseVO.getNumber());
		    	map.put(headerList[1], zhxyInfoCourseVO.getName());
		    	data.add(map);
			}
		}
		return Utils.genericSheet("课程列表(参考)", headList, data, work);
	}
