使用poi操作模板文件重新生成新的word表单文件

问题：本人在项目中使用poi生成word表单文件，发现格式排版非常麻烦不说，还有个比较严重的问题是，wps跟office格式不兼容，用了2种方法都没有让这个两种打开的样式一致。不是office格式排版有问题就是wps格式排版有问题，研究了一天，最后决定用模板文件去生成新的文档比较容易，也不会有兼容性问题，并且也不用麻烦的去写很多样式做，而且可以简化代码变成工具类。解决了一个样式就要写一个生成类的问题，下面就来介绍一个下。

一、先来看一下模板文件

首先先创建一个格式符合要求的表单文档，所有需要动态值的地方用${}括起来自定义名称 例如${name}等等。

二、准备一个工具类。

} catch (FileNotFoundException e) {

三、操作类

}

四 、controller类调用方法

/**

*

*/
@RequestMapping("/out/downloadTemplet")
public ResponseEntity<byte[]> downloadTemplet(Model model,HttpServletRequest request,HttpSession session,String visitId){

String userId=null;
Object sessions = session.getAttribute("user");
if (sessions == null) {
return null;
}
if (User.class.equals(sessions.getClass())) {
User user = (User) sessions;
userId=Integer.toString(user.getId());
}

VisitApply visitApply=new VisitApply();
visitApply.setVisitId(visitId);
//获取外访申请信息
VisitApply info=outVisitServiceimpl.selectVisitApplyData(visitApply);
//获取案件信息
CaseHead t = new CaseHead();
t.setCaseid(info.getCaseid());
t.setCompanycode(info.getCompanyCode());
CaseBo caseBo=caseHeadService.getCaseHeadDetailByExample(t);
//获取案件联系方式信息
CaseContact caseContact=new CaseContact();
caseContact.setCaseid(info.getCaseid());
List<CaseContact> contacts=caseContactService.selectCaseConcatList(caseContact);

//生成文件名称
String fileName="外访报告填写模板"+DateUtil.formatDate(new Date())+".zip";
//生成下载文件word
/*DownLoadTemplet download=new DownLoadTemplet(info,caseBo,contacts);*/
//生成下载文件word表单
/*DownLoadTableTemplet download=new DownLoadTableTemplet(info,caseBo,contacts);*/
//生成下载文件word模板替换生成表单
Map<String, Object> params=dowloadWordService.dowloadModelWord(info, caseBo, contacts);
//模板地址
String templatePath = this.getClass().getClassLoader().getResource("/model.docx").getPath();

System.out.println(templatePath);
String wordFileName="外访报告信息填写模板";//生成文件名
DownLoadTable download=new DownLoadTable(params,templatePath,wordFileName);

byte[] taskFile=download.createZip();
HttpHeaders headers = new HttpHeaders();
//下载
if(taskFile!=null){
headers.setContentLength(taskFile.length);
}
headers.setContentType(MediaType.APPLICATION_OCTET_STREAM);
setFileName(request, headers, fileName);
//下载文件
return new ResponseEntity<byte[]>(taskFile, headers, HttpStatus.OK);

}

五，params参数的sercive实现类

package org.uz.dxt.service.bankbase.impl;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.springframework.stereotype.Service;
import org.uz.dxt.model.bankbase.CaseBo;
import org.uz.dxt.model.bankbase.VisitApply;
import org.uz.dxt.model.common.CaseContact;
import org.uz.dxt.service.bankbase.DowloadWordService;

@Service
public class DowloadWordServiceImpl implements DowloadWordService {

@Override
public Map<String, Object> dowloadModelWord(VisitApply info, CaseBo caseBo, List<CaseContact> contacts) {

Map<String, Object> params = new HashMap<String, Object>();
params.put("${caseid}",  info.getCaseid());
params.put("${applyName}",  info.getApplyName());
params.put("${applyTime}", info.getApplyTime());
params.put("${visitPurpose}", info.getVisitPurpose());
params.put("${addressType}", info.getAddressType());
params.put("${appointName}", info.getAppointName());
params.put("${bankName}", info.getBankName());
params.put("${name}", info.getName());
params.put("${doccode}", info.getDoccode());
params.put("${cardcode}", info.getCardcode());
params.put("${overmoney}", info.getOvermoney());
String deputecapital="";
if(caseBo.getDeputecapital() != null){
deputecapital=caseBo.getDeputecapital().toString();
}else{
deputecapital="无";
}

String moneybalance="";
if(caseBo.getMoneybalance() != null){
moneybalance=caseBo.getMoneybalance().toString();
}else{
moneybalance="无";
}
params.put("${deputecapital}", deputecapital);
params.put("${moneybalance}", moneybalance);
String contactInfo="";
if (contacts != null) {
for(int i=0;i<contacts.size();i++){
String type="";
String address="";
String name="";
if (contacts.get(i).getValid() != 0) {
if (contacts.get(i).getContacttype() == "0") {
type="电话";
}else if (contacts.get(i).getContacttype() == "1") {
type="邮件";
}else if (contacts.get(i).getContacttype() == "2") {
type="QQ";
}else if (contacts.get(i).getContacttype() == "3") {
type="微信";
}else if (contacts.get(i).getContacttype() == "4") {
type="地址";
}else {
type="无";
}

if (contacts.get(i).getCoofficeaddr() != null) {
address=contacts.get(i).getCoofficeaddr();
}else{
address="无";
}
if (contacts.get(i).getContactname() != null) {
name=contacts.get(i).getContactname();
}else{
name="不详";
}
contactInfo=contactInfo+"联系人:"+name+"  类型:"+type+"  关系:"+contacts.get(i).getRelation()+"  联系方式:"+contacts.get(i).getInfo()+"  单位地址:"+address;
}
}

}else{
contactInfo="无联系方式";
}

params.put("${visitAddress}", info.getVisitAddress());
params.put("${contactInfo}", contactInfo);
return params;
}

}

六、生成后的表单效果

七、如果觉得麻烦看的不太明白我建议一点一点尝试，这里放一个简单的测试main方法，当你使用这个明白以后再琢磨一下怎么适合自己的需求去写代码。

还是要用到xwp工具类，模板用本地路径即可，运行mian方法查看结果

package org.uz.dxt.service;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.util.HashMap;
import java.util.Map;

import org.apache.poi.xwpf.usermodel.XWPFDocument;

public class TestModel {

public static void main(String[] args) throws  Exception {
Map<String, Object> params = new HashMap<String, Object>();

params.put("${applyName}", "aaa");
params.put("${applyTime}", "bbb");
params.put("${visitPurpose}", "ccc");

Xwp xwpfTUtil = new Xwp();

XWPFDocument doc;
String templatePath = "e:/word/model.docx";  //模板路径
InputStream is = new FileInputStream(templatePath);

doc = new XWPFDocument(is);

//替换表格里面的变量
xwpfTUtil.replaceInTable(doc, params);
FileOutputStream fos = new FileOutputStream("e:/word/ddd.docx");//生成文档的路径

doc.write(fos);

xwpfTUtil.close(fos);

fos.flush();
fos.close();
}

}
