wps的对poi合并的单元生成的word无效，
解决方法：
在服务器中生成word文件然后使用jacob插件重新保存一下在下载就可以解决
file = new File(filePath + fileName); //在服务器中保存的文件
// 重新保存文件
Object doc;
Variant f;
ActiveXComponent app = new ActiveXComponent("Word.Application");
try {
app.setProperty("Visible", new Variant(false));
Dispatch docs = app.getProperty("Documents").toDispatch();
doc = Dispatch.invoke(docs, "Open", 1, new Object[] { filePath + fileName, new Variant(false), new Variant(true) }, new int[3]).toDispatch();
Dispatch.call(app.getProperty("Selection").toDispatch(), "EndKey", new Object[] { new Variant(6) });
file = new File(filePath + "new\\");
if (file.mkdirs()) {
file.mkdirs();
}
Dispatch.invoke((Dispatch) doc, "SaveAs", 1, new Object[] { filePath + "new\\" + fileName, new Variant(1) }, new int[3]);
f = new Variant(false);
} catch (Exception e) {
throw new RuntimeException("重新保存失败:" + e);
} finally {
app.invoke("Quit", new Variant[0]);
}
file.delete();
try {
file = new File(filePath + "new\\" + fileName);//保存后的文件
InputStream fis = new FileInputStream(file);
byte[] buffer = new byte[fis.available()];
fis.read(buffer);
fis.close();
// 清空response
response.reset();
fileName = "文件名称.docx";
// 1.设置文件ContentType类型，这样设置，会自动判断下载文件类型
// response.setContentType("multipart/form-data");
// response.setContentType("application/x-ppt;charset=GBK");
// 2.设置文件头：最后一个参数是设置下载文件名(假如我们叫a.pdf)
response.setHeader("Content-Disposition", "attachment;fileName=" + Encodes.urlEncode(fileName));
response.setHeader("Content-type", "application-download");
response.setCharacterEncoding("utf-8");
OutputStream toClient = new BufferedOutputStream(response.getOutputStream());
// 下载ppt文件
toClient.write(buffer);
toClient.flush();
toClient.close();
file.delete();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
