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
/**
* 合并多个word为一个Word
*
* @param srcdocs
* @param destDoc
* @return
*/

//1.校验
if (srcdocs.size() == 0 || srcdocs == null) {

}

long start = System.currentTimeMillis();
//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
app.setProperty("Visible", new Variant(false));
//获得Documents对象
Object docs = app.getProperty("Documents").toDispatch();
// 2.2.打开第一个文件
doc = Dispatch.invoke(
(Dispatch) docs, // 参数1:调用目标
"Open", // 参数2
Dispatch.Method, //参数3
new Object[]{(String) srcdocs.get(0), new Variant(false), new Variant(true)}, // 参数4
new int[3] //参数5
).toDispatch();
// 2.3.追加后续文件
for (int i = 1; i < srcdocs.size(); i++) {
Dispatch.invoke(
app.getProperty("Selection").toDispatch(), //参数1
"insertFile",
Dispatch.Method,
new Object[]{(String) srcdocs.get(i), "", new Variant(false), new Variant(false), new Variant(false)}, // 参数4
new int[3] // 参数5
);
}
//2.4.如果目的word存在,则删除
File tofile = new File(destDoc);
if (tofile.exists()) { // 目标pdf存在,则删除,前提未使用
tofile.delete();
}
// 2.5.保存为新的word
Dispatch.invoke((Dispatch) doc, "SaveAs", Dispatch.Method, new Object[]{destDoc, new Variant(1)}, new int[3]);
Variant f = new Variant(false);
Dispatch.call((Dispatch) doc, "Close", f); // 把close属性赋值个f
long end = System.currentTimeMillis();
System.out.println("转换完成..用时：" + (end - start) + "ms.");
} catch (Exception e) {
System.out.println("========合并Word文件失败：" + e.getMessage());

2.2.2 测试
/**
* word转pdf
*/
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";
List srcDocs = new ArrayList<>();
srcDocs.add("D:/Java通过jacob操作wps记录1.doc");
srcDocs.add("D:/Java通过jacob操作wps记录2.doc");
boolean mergeResult = d.mergeMultipleWord2Single(srcDocs, descDoc);
if (mergeResult) {
System.out.println("合并成功!");
d.wordToPDF(descDoc, descPdf);
} else {
System.out.println("合并失败!");
}

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
