POI 生成 word 文档 简单版（包括文字、表格、图片、字体样式设置等）

POI 生成word 文档 一般有两种方法：

① word模板 生成word 文档 ；

② 写代码直接生成 word 文档；

我这里演示的是第二种方法，即写代码生成 word文档，不多说废话，直接代码；

/**
	 * 镇街日报导出word
	 */
	@RequestMapping(params = "exportWordForTownDaily")
	public void exportWordForTownDaily(HttpServletResponse response ,String selectDate){
		if(StringUtils.isNullOrEmpty(selectDate)){
			return;
		}
		SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
		try{
			sdf.parse(selectDate);
		}catch (Exception e){
			e.printStackTrace();
			return;
		}
		CaseEntity entity = new CaseEntity();
		entity.setRepotingTime_begin(selectDate + " 00:00:00");
		entity.setRepotingTime_end(selectDate + " 23:59:59");
		//获取镇街实际扣分
		List<CaseEntity> caseEntityList = statisticsService.getTownActualScore(entity);
		//获取各镇街情况
		List<Map<String, Object>> townDaily = statisticsService.townDaily(entity);
		//格式化查询日期(年月日)
		SimpleDateFormat sdf2 = new SimpleDateFormat("yyyy年MM月dd日");
		try {
			selectDate = sdf2.format(sdf.parse(selectDate));
		} catch (ParseException e) {
			e.printStackTrace();
		}

　　 效果如下图所示：
