Ami*_*ira 15 java velocity apache-poi
我想加载一个模板word文档来添加内容并保存为新文档.我正在研究.doc文件.
经过长时间的研究,我只找到了docx的解决方案:
http://www.smartjava.org/content/create-complex-word-docx-documents-programatically-docx4j
http://www.sambhashanam.com/mail-merge-in-java-for-microsoft-word-document-part-i/
所以我想替换以这种格式编写的任何变量:$VAR它的值.我可以用velocity或Apache-poi来做,它的最佳解决方案是什么.任何帮助将不胜感激.

是的,您可以使用Apache-POI来完成.您的变量名称必须是唯一的.请参阅以下代码
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.usermodel.CharacterRun;
import org.apache.poi.hwpf.usermodel.Paragraph;
import org.apache.poi.hwpf.usermodel.Range;
import org.apache.poi.hwpf.usermodel.Section;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;
public class HWPFTest {
public static void main(String[] args){
String filePath = "F:\\Sample.doc";
POIFSFileSystem fs = null;
try {
fs = new POIFSFileSystem(new FileInputStream(filePath));
HWPFDocument doc = new HWPFDocument(fs);
doc = replaceText(doc, "$VAR", "MyValue1");
saveWord(filePath, doc);
}
catch(FileNotFoundException e){
e.printStackTrace();
}
catch(IOException e){
e.printStackTrace();
}
}
private static HWPFDocument replaceText(HWPFDocument doc, String findText, String replaceText){
Range r1 = doc.getRange();
for (int i = 0; i < r1.numSections(); ++i ) {
Section s = r1.getSection(i);
for (int x = 0; x < s.numParagraphs(); x++) {
Paragraph p = s.getParagraph(x);
for (int z = 0; z < p.numCharacterRuns(); z++) {
CharacterRun run = p.getCharacterRun(z);
String text = run.text();
if(text.contains(findText)) {
run.replaceText(findText, replaceText);
}
}
}
}
return doc;
}
private static void saveWord(String filePath, HWPFDocument doc) throws FileNotFoundException, IOException{
FileOutputStream out = null;
try{
out = new FileOutputStream(filePath);
doc.write(out);
}
finally{
out.close();
}
}
}

最近我必须解决同样的问题,但是使用.docx文档。尝试上述方法会导致以下错误(如本文所述):
org.apache.poi.poifs.filesystem.OfficeXmlFileException:提供的数据似乎位于 Office 2007+ XML 中。您正在调用 POI 中处理 OLE2 Office 文档的部分。您需要调用 POI 的不同部分来处理此数据(例如 XSSF 而不是 HSSF)
最后,我必须按如下方式更改代码(在我的例子中,.docx 文件位于资源文件夹内):
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.net.URISyntaxException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
public class XWPFTest {
public static void main(String[] args) throws URISyntaxException, IOException {
String resourcePath = "template.docx";
Path templatePath = Paths.get(XWPFTest.class.getClassLoader().getResource(resourcePath).toURI());
XWPFDocument doc = new XWPFDocument(Files.newInputStream(templatePath));
doc = replaceTextFor(doc, "UNIQUE_VAR", "MyValue1");
saveWord("C:\\document.docx", doc);
}
private static XWPFDocument replaceTextFor(XWPFDocument doc, String findText, String replaceText){
doc.getParagraphs().forEach(p ->{
p.getRuns().forEach(run -> {
String text = run.text();
if(text.contains(findText)) {
run.setText(text.replace(findText, replaceText), 0);
}
});
});
return doc;
}
private static void saveWord(String filePath, XWPFDocument doc) throws FileNotFoundException, IOException{
FileOutputStream out = null;
try{
out = new FileOutputStream(filePath);
doc.write(out);
}
catch(Exception e) {
e.printStackTrace();
}
finally{
out.close();
}
}
}

PS 我必须删除 $ 因为 .docx 中的管理是单独的运行,所以我必须选择唯一的 var 名称的方法。我需要以下 Apache POI 依赖项:
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>3.17</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.17</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-scratchpad</artifactId>
<version>3.17</version>
</dependency>
