Java通过JACOB操作WPS记录
1概述
JACOB-JavaCOMBridge标准的操作word、excel工具包。用户本地系统中安装Word的应用程序可选(office、wps有其一即可)。
1.****1****下载****JACOB
1.2环境准备
本机是64位,拷贝机器版本部署对应的jacob-1.19-x64.dll到C:\Program Files\Java\jdk1.8.0_60\bin。
将jacob.jar放到响应的工程目录即可。

2.2 合并多个Word为一个Word
2.2.1 mergeMultipleWord2Single
/**

//1.校验

//2.判断
ActiveXComponent app = null;
Object doc = null;
try {
// app = new ActiveXComponent("Word.Application"); // 基于microsoft office
app = new ActiveXComponent("KWPS.Application"); // 基于kwps的方式,具体和调用ActiveX控件有关
// 2.1.设置word不可见

//获得Documents对象

// 2.2.打开第一个文件
doc = Dispatch.invoke(
(Dispatch) docs, // 参数1:调用目标

Dispatch.Method, //参数3

//2.4.如果目的word存在,则删除

2.2.2 测试
/**

*/
public static void mergeMultipleWord2SingleTest() {
MyWord2PDF d = new MyWord2PDF();
String descDoc = "D:/Java通过jacob操作wps记录_new.doc";
String descPdf = "D:/Java通过jacob操作wps记录_new.pdf";

2.3合并后的Word生成PDF
参见2.1.1
3常见错误及解决
3.1.错误一
错误:
文档转换失败：Can't get object clsid from progid
解决:
主要是创建ActiveXComponent的姿势不对,调整如下:
//app = new ActiveXComponent("Word.Application"); // 基于microsoft office app = new ActiveXComponent("KWPS.Application"); // 基于kwps的方式
