Java导出word文档

 

1、新建一个word文档, 输入如下内容:

(里面的Tb1开头就是我们需要替换的占位字段，这里的占位字段不要太复杂，比如${Tb123}，因为后面另存为xml后，多种类型的字符会发生拆分)

2、将该word文件另存为xml格式(注意是另存为,不是直接改扩展名)

3、将xml文件的扩展名直接改为ftl

(在文本编辑器里面打开ftl模版。然后搜索在word里填充的占位符。然后替换成后面能被替换的格式。比如，把Tb111，替换成${tb111}。

这里可能原始的占位符发生了截断，比如本来是Tb111，但是在ftl模版里面成了Tb1~<dafda<11。这时就要把中间的那些删掉。最后替换后的格式就是标准的可替换参数)
