我正在寻找读写MS Word文档的java库。 我要做的是:
用户可以对文件进行更新。
我搜索并找到了POI Apache和UNO OpenOffice。 第一个可以轻松地读取模板并用来自DB的我自己的数据替换任何占位符。我没有找到任何关于合并两个或更多文档的内容。 OpenOffice UNO看起来更稳定但也很复杂。此外,我不确定它是否有能力合并文件..
我们正在寻找正确的方向?
我认为另一个解决方案是将doc文件转换为docx。通过这种方式,我找到了更多可以帮助我们合并文档的库。 但是我该怎么做呢?
谢谢!

您可以查看Docmosis,因为它提供了您提到的四个功能(数据填充,模板/文档合并,DOC格式和Java界面)。它有几种风格(下载,在线服务),但您可以注册免费试用云服务,看看Docmosis是否可以做你想要的(然后你不需要安装任何东西)或在线阅读文档。
它使用OpenOffice(您可以从开发人员指南中看到安装说明),它可以在文档之间进行相当不错的转换。 UNO API有一些复杂性 - 我建议使用Docmosis或JODReports将您的项目直接与UNO隔离。
希望有所帮助。

我已经开发了下一堂课(使用Apache POI):
import java.io.InputStream;
import java.io.OutputStream;
import java.util.ArrayList;
import java.util.List;
import org.apache.poi.openxml4j.opc.OPCPackage;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTBody;
public class WordMerge {
private final OutputStream result;
private final List<InputStream> inputs;
private XWPFDocument first;
public WordMerge(OutputStream result) {
this.result = result;
inputs = new ArrayList<>();
}
public void add(InputStream stream) throws Exception{
inputs.add(stream);
OPCPackage srcPackage = OPCPackage.open(stream);
XWPFDocument src1Document = new XWPFDocument(srcPackage);
if(inputs.size() == 1){
first = src1Document;
} else {
CTBody srcBody = src1Document.getDocument().getBody();
first.getDocument().addNewBody().set(srcBody);
}
}
public void doMerge() throws Exception{
first.write(result);
}
public void close() throws Exception{
result.flush();
result.close();
for (InputStream input : inputs) {
input.close();
}
}
}
及其用途:
public static void main(String[] args) throws Exception {
FileOutputStream faos = new FileOutputStream("/home/victor/result.docx");
WordMerge wm = new WordMerge(faos);
wm.add( new FileInputStream("/home/victor/001.docx") );
wm.add( new FileInputStream("/home/victor/002.docx") );
wm.doMerge();
wm.close();
}
