Java操作Word文档封装类

基于开源项目jacob的基础上，封装了操作Word常用的方法和接口。jacob项目是通过java操作com接口的工具，这部分代码是封装了操作word的常用com接口。需要配合jacob.dll和jacob.jar使用。

说到底还是要依赖于word。。。。

3 楼 hejianhuacn 2010-03-27  

OpenOffice 里面代码可以借鉴

2 楼 lyndon.lin 2010-03-26  

看具体情况选择吧，因为我一直都是在微软系统上开发。

1 楼 gaoyuntao2005 2010-03-26  

这种操作方法在linux 下不行。不支持dll.还有必须在服务器上安装word ，这样觉得不好。可以试试POI
