[转]Java2word(jacob)操作word文档--eclipse的兼容问题解决

前一个月搞的一个招生项目需要动态生成word文档并插入数据。好找一遍发现了Java2Word这个包。java2word是com桥jacob包的封装，它专门针对word文档的操作做了封装，方便使用。

说实话，java2word本身做的不咋地，兼容性不好，也不大稳定。在设计解决方案的时候因为这一点费了不少劲。现总结如下：

1.   安装java2word。该过程将其中的jacob.dll动态链接库复制到system32目录下，可能还有注册操作；

2.   将java2word.jar包复制到tomcat的lib下，引用至工程的build path中，或者直接复制到工程lib下。这两步保证了其中的jacob类正常连接com组件；

3.   编写访问类（见附录）；
Java2word中每个word文档对应一个document对象。Document对象拥有open、close、insert以及find和 replace等多种方法。另外，document还含有style属性及其getter和setter来设置word文档指定元素的格式，但这一属性我没用到。原因是只需在目标word文档中待插入数据的位置预先设置好格式，即可保证插入后的文档符合要求（除非需要动态改变）。

4.   Eclipse的兼容性问题。
Java2word，或者说jacob本身对eclipse支持不是很好，在netbean上倒是可以正常调用。对于使用myeclipse的工程，仅按照上面设置可能会出错。这时可作如下处理：
将jacob.dll复制一份到eclipse使用的jdk/bin下（无需注册），这样就可以保证Jacob or java2word的正常工作。（这问题当时快把我给折腾死了）

5.   Word本身对象模型的兼容性问题。
由于涉及到com组件，就必须考虑到与其通信的com组件本身的特性。我在开发时，系统环境是word 2007（当然是D版^^），结果错误百出，经常报java.lang.exception或者application.word没有注册的错误。在朋友提醒后我才恍然大悟：word2003跟2007的对象模型压根儿就是不一样的（至少有差别）。在换成2003后，问题搞定。

后话：其实对于传统word文档的操作一般都会使用asp.net等语言去完成，java与com组件的通信还是其一大软肋。当前的com桥有poi、jcom、jacob等。其中poi简洁易用但功能较弱，jacob功能强大但上手较慢，需视需求而定。

但这个问题在以openxml为基础的2007文档中是不存在的。2007文档实际上是对一组xml的压缩包，其内部结构可以通过将.docx的文档改名为.rar后打开查看便一目了然。这时我们只需要找到存储数据的xml，按照其格式来读取即可。

至于2007格式的word文档，见我转载的文章Java操作office 2007文档。
