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();
        }
