其实导入导出功能实现起来很简单，关键是你得导入正确的jar包，然后调用里面的方法就行了。

/*
* 依赖jar包：
* dom4j-1.6.1.jar
* geronimo-stax-api_1.0_spec-1.0.jar
* poi-3.7-20101029.jar
* poi-ooxml-3.7-20101029.jar
* poi-ooxml-schemas-3.7-20101029.jar
* poi-scratchpad-3.7-20101029.jar
* xmlbeans-2.3.0.jar
* commons-logging-1.1.jar

    context = readDoc("E:\\4s\\sss.docx");
    System.out.println(context);

/*  String[] aa = context.split("\\s+"); 

    List dataList = new ArrayList();
    int num = aa.length / 3;
    int j = 0;
    for(int i = 0 ; i  maps = new HashMap();
        maps.put("姓名", aa[j]);
        maps.put("性别", aa[j+1]);
        maps.put("工号", aa[j+2]);

里面导出的功能不怎么完整，还有一些导出的字体样式，字体大小，背景颜色等等。。。大概就这些代码了，有jar包找不到的可以给小弟留下你们邮箱。我这里也有完整的demo，有需要的可以也可以留下邮箱。。。
