最近项目里要做一个根据客户提供的word模板导出word的功能，方法有很多，比如easyPoi（对word的支持并不是很好），freeMark（太麻烦不想研究），以及poi-tl，
最后研究了半天发现也就只有poi-tl比较符合我的需求，特意记录下以防日后用到忘记了。
这是想要的word结果
这是我的word模板
代码如下：
try {DecimalFormat df = new DecimalFormat("###################.###########");SettlementResponse.All settlement = getDetails(settlementId);Map<String, Object> params = new HashMap<>();params.put("guestName", settlement.getBase().getGuestName());String visitStart = DateUtil.timestamp2String(settlement.getBase().getVisitTimeStart(),"yyyy年MM月dd日");String visitEnd = DateUtil.timestamp2String(settlement.getBase().getVisitTimeStart(),"MM月dd日");params.put("visitDate", visitStart+ "-" + visitEnd);SettlementResponse.Detail detail = settlement.getDetail();double total = 0;//住宿费列表if (MyUtil.isNotBlank(detail.getAccomResponse())){SettlementAccomResponse accomResponse = detail.getAccomResponse();Map<String,Object> accomMap = getAccomdation(accomResponse);params.put("accomList", accomMap.get("accomList"));params.put("accomOwn", accomMap.get("accomOwn"));params.put("accomTotal", accomMap.get("accomTotal"));total = total + accomResponse.getSubtotal().doubleValue();}//会场费列表List<Map<String,Object>> meetList = new ArrayList<>();if (CollectionUtil.isNotEmpty(detail.getMeetingResponseList())){Map<String,Object> meetingMap = getMeeting(detail.getMeetingResponseList());params.put("meetList", meetingMap.get("meetList"));params.put("meetTotal",meetingMap.get("meetTotal"));total = total + Double.parseDouble(meetingMap.get("meetTotal").toString());} else{meetList.add(new HashMap<String, Object>() {{put("meetTime", "");put("meetPlace", "");put("roomName", "");put("meetCost", "");}});params.put("meetList",meetList);}//餐饮费列表if (MyUtil.isNotBlank(detail.getMealsResponse())){List<SettlementMealsResponse.MealsDetail> mealsDetailList = detail.getMealsResponse().getMealsDetailList();Map<String,Object> mealsMap = getMeals(mealsDetailList);params.put("workMeal", mealsMap.get("workMeal"));params.put("dailMeal", mealsMap.get("dailMeal"));params.put("otheMeal", mealsMap.get("otheMeal"));params.put("mealsOwn", df.format(detail.getMealsResponse().getOwnExpense()));params.put("mealTotal", df.format(detail.getMealsResponse().getSubtotal()));total = total + detail.getMealsResponse().getSubtotal().doubleValue();}//其他费用列表List<Map<String,Object>> otherList = new ArrayList<Map<String,Object>>();if (CollectionUtil.isNotEmpty(detail.getOthersList())){Map<String,Object> otherMap = getOther(detail.getOthersList());params.put("otherList", otherMap.get("otherList"));params.put("otherTotal", otherMap.get("otherTotal"));total = total + Double.parseDouble(otherMap.get("otherTotal").toString());}else{otherList.add(new HashMap<String, Object>() {{put("otherRemark", "");put("otherCost", "");}});params.put("otherList", otherList);}//文印费params.put("printRemark", detail.getPrints().getDescription());params.put("printTotal", df.format(detail.getPrints().getCost()));total = total + detail.getPrints().getCost().doubleValue();params.put("total", df.format(total));//word模板地址，如果项目需要部署在linux环境中，需要以流的方式读取文件否则会读取不到InputStream resource= this.getClass().getClassLoader().getResourceAsStream("static/template/settlement.docx");//渲染表格，new HackLoopTableRenderPolicy(true)即模板标签和循环行在同一行而不是在上一行HackLoopTableRenderPolicy policy = new HackLoopTableRenderPolicy(true);Configure config = Configure.builder().bind("accomList", policy).bind("meetList", policy).bind("workMeal", policy).bind("dailMeal", policy).bind("otheMeal", policy).bind("otherList", policy).build();XWPFTemplate template = pile(resource, config).render(params);String fileName = "接待任务费用结算表" + "-" + System.currentTimeMillis();ExportWordUtils.downloadWord(response, fileName, template);} catch (Exception e) {e.printStackTrace();}
