java生成的word图表不能编辑吗

Posted 2023-05-06

参考技术A java生成的word图表不能编辑。java直接生成的word图表不能编辑，必须要启动word后启用编辑模式才能进行编辑。

java生成word文档的问题

需要用到什么jar包？能否给个代码示例？
一楼总是这么威武

Jacob解决Word文档的读写问题收藏
Jacob 是Java-COM Bridge的缩写，它在Java与微软的COM组件之间构建一座桥梁。使用Jacob自带的DLL动态链接库，并通过JNI的方式实现了在Java平台上对COM程序的调用。Jacob下载的地址为：

http://sourceforge.net/project/showfiles.php?group_id=109543&package_id=118368

配置：

(1)将解压包中的jacob.dll（x86常用,x64)拷到jdk安装目录下的jre\bin文件夹或windows安装路径下的WINDOWS\system32文件夹下

(2)将jacob.jar文件拷到classpath下即可

常见问题解决:

对于”java.lang.UnsatisfiedLinkError: C:\WINDOWS\system32\jacob-1.14.3-x86.dll: 由于应用程序配置不正确，应用程序未能启动。重新安装应用程序可能会纠正”这个问题,可以通过

重新下载Jacob的jar及dll文件(最好版本比现在的低,如1.11)解决

参考技术A 1-apache的POI,此方法对Excel的导出做的很好，目前对Word的导出方面的功能尚未完全。

2-纯JavaScript脚本实现。主要通过客户端调用本机Office组件来实现。

3-在JSP页面引入头文件实现。

纯JavaScript脚本实现细节方面大体是创建一个word组件ActiveXObject('Word.Application')，用js通过表ID取得表内容然后保存到word，要注意的是js实现有很多不好的地方，例如Internet选项需要把ActiveX空间全部启用，安全级别设置为中。这样的话岂不是每台机器都要配置一下。其次每次生成word文档以后弹出对话框（无法保存此文件,因为它已在别处打开(C:\...\STARTUP\Powerword.dot)），出现此问题就需要把C:\Documents and Settings\当前用户名\Application Data\Microsoft\Word\STARTUP下的Powerword.dot文件删除，每次遇到此问题就需要删除文件来解决，十分不方便。

JSP页面引入来实现Word保存就方便多了，但是也有不足的地方，首先如果需要引入
<meta http-equiv="Content-Type" content="application/msword; charset=gb2312" />

如果需要下载的话就引入

<%@ page contentType="application/msword; charset=gb2312" %>

其实如果大家用框架做就方便多了，比如Struts2。在Action里直接写如下代码：

if(out!=null)
String fileName="";
fileName+="评价报告.doc";
try
HttpServletResponse response = ServletActionContext.getResponse();
response.setHeader("Content-disposition","attachment; filename="+new String(fileName.getBytes("GB2312"), "8859_1"));
catch (UnsupportedEncodingException e)
e.printStackTrace();


out是jsp页面表单元素，一个button，用于提交表单到相应Action进行Word下载。Action设置jsp页面头文件。这样每次点击button就可以把相应jsp页面的内容保存到Word中并且支持下载，Word中内容并且是可编辑状态。

不足的地方在于由于表内容是动态生成，有的需要先查看在下载Word，就需要另外建立一个新JSP页面进行Word下载，当然首先要在struts.xml里配置好页面转向。

新建立的页面传值同查看页面要保持一样。 参考技术B 如果只是生成word文档就这样就行了
File file=new File("d:\\xxx.word");
if(!file.exists())

file.createNewFile();
