java导出到Word

Posted 2021-01-21 doublet

1、操作步骤：

　(1)、新建word模板，凡是需要填充的数据用${xxxx},编辑好word文档后，另存为word文档的(*.xml),命名为mediteAgreementBook.xml（名字随意更改）

 （2)、在web项目中webroot目录下新建exptemplate文件夹，并将mediteAgreementBook.xml文件放到exptemplate文件夹下

 （3)、拷贝DocUtil.java工具类到项目中，如下面的调用实例
   (4)、返回相对路径，自动下载Word文档

2、添加maven依赖

<dependency>  
    <groupId>org.freemarker</groupId>  
    <artifactId>freemarker</artifactId>  
    <version>2.3.23</version>  
</dependency> 

3、Java代码

 1 @Override
 2     public String createMediateAgreementBookByCaseId(Long id) {
 3         TrafficAccidentJudicial param = new TrafficAccidentJudicial();
 4         param.setCaseId(id);
 5         List<TrafficAccidentJudicial> listData = trafficAccidentJudicialDao.getMediateAgreementBookDataByCaseId(param);
 6         Map<String,String> map = new HashMap<>();
 7         map.put("no", listData.get(0).getAccidentNo() != null ? listData.get(0).getAccidentNo() : "");
 8         
 9         map.put("na1", listData.get(0).getName() != null ? listData.get(0).getName() : "");
10         map.put("s1", listData.get(0).getSexName());
11 //        map.put("n1", listData.get(0).getNationName());
12         map.put("n1", "");
13         map.put("a1", listData.get(0).getAge() != null ? listData.get(0).getAge() + "" : "");
14         map.put("c1", listData.get(0).getCardNo() != null ? listData.get(0).getCardNo() : "");
15         map.put("j1", listData.get(0).getVocation() != null ?  listData.get(0).getVocation() : "");
16         map.put("t1", listData.get(0).getTelephone() != null ? listData.get(0).getTelephone() : "");
17         map.put("ad1", listData.get(0).getPresentAddress() != null ? listData.get(0).getPresentAddress() : "");
18         
19         map.put("na2", listData.get(1).getName() != null ? listData.get(1).getName() : "");
20         map.put("s2", listData.get(1).getSexName());
21 //        map.put("n1", listData.get(0).getNationName());
22         map.put("n2", "");
23         map.put("a2", listData.get(1).getAge() != null ? listData.get(1).getAge() + "" : "");
24         map.put("c2", listData.get(1).getCardNo() != null ? listData.get(1).getCardNo() : "");
25         map.put("j2", listData.get(1).getVocation() != null ?  listData.get(1).getVocation() : "");
26         map.put("t2", listData.get(1).getTelephone() != null ? listData.get(1).getTelephone() : "");
27         map.put("ad2", listData.get(1).getPresentAddress() != null ? listData.get(1).getPresentAddress() : "");
28         
29         map.put("dis", listData.get(1).getDisputeMatter() != null ? listData.get(1).getDisputeMatter() : "");
30         map.put("me", listData.get(1).getMediateRecord() != null ? listData.get(1).getMediateRecord() : "");
31         map.put("ad", listData.get(1).getAgreementDate() != null ? listData.get(1).getAgreementDate() : "");
32         
33          Calendar nowDate = Calendar.getInstance();
34         
35         map.put("y", nowDate.get(Calendar.YEAR) + "");
36         map.put("m",  (nowDate.get(Calendar.MONTH) + 1) + "");
37         map.put("d",  nowDate.get(Calendar.DAY_OF_MONTH) + "");

40         String newWordName = "测试文件名称.doc";
41         HttpServletRequest request =  ServletActionContext.getRequest();  //Struts2获取request
42         HttpServletResponse response = ServletActionContext.getResponse(); //Struts2获取response
43         return exportWord(request, response, newWordName, map);
44     }
