关于java中用itext导出word的一点想法

Posted 2020-10-03

这几天在项目组只做了很少的事情，主要还是自己不认真地说.我的部分是要负责用itext导出word文档这一块，之前看到大佬们做出了EXCEL部分觉得很是惊奇，就像刚刚接触html一样的感觉。但是毕竟自己的任务就要好好的去完成，所以经过努力还是取得了一点的成果.的。

先上一个效果图

接下来就是代码了，码字不易，还有事情要做~~

从前台利用Ajax传入到后台部分后，利用itext方法导出word，需要注意的是document.close和out.close这两个部分，没有close很容易出错。

public void exportJdyWord(HttpServletResponse response,HttpServletRequest request,String xsId) throws UnsupportedEncodingException {
for(int c=1;c<=2;c++){
String s = " select c_username from c_kdxsyb where c_xs_id = ? and c_xs_rq = ‘"+c+"‘";
List<Map<String,Object>> username = jt.queryForList(s,xsId);
Set<String> set = new HashSet<String>();
for(int i=0;i<username.size();i++){
Map <String, Object> map = username.get(i);
Object vala = map.get(username);
if(vala!=null){String v = vala.toString();
set.add(v);}
}
response.setContentType("application/msword");//下载
String agent = request.getHeader("USER-AGENT").toLowerCase();
String codedFileName = java.net.URLEncoder.encode("监督员表", "UTF-8");
if (agent.contains("firefox")) {
response.setCharacterEncoding("utf-8");
response.setHeader("content-disposition",
"attachment;filename=" + new String("监督员".getBytes(), "ISO8859-1") + ".doc");
} else {
response.setHeader("content-disposition", "attachment;filename=" + codedFileName + ".doc");
}
