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();
}
