Java代码替换Word文件中指定字符的流程:
- 打开Word文件
- 读取Word文件的内容
- 替换指定字符
- 保存修改后的Word文件
流程图示例:
flowchart TD
A[打开Word文件] --> B[读取文件内容]
B --> C[替换指定字符]
C --> D[保存修改后的Word文件]
代码示例:
- 打开Word文件使用Apache POI库的方法:
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;
public void openWordFile(String filePath) {
try {
FileInputStream fis = new FileInputStream(filePath);
XWPFDocument document = new XWPFDocument(fis);
// 其他操作
fis.close();
} catch (IOException e) {
e.printStackTrace();
}
}
- 读取Word文件的内容:
public String readWordFile(XWPFDocument document) {
StringBuilder content = new StringBuilder();
List<XWPFParagraph> paragraphs = document.getParagraphs();
for (XWPFParagraph paragraph : paragraphs) {
content.append(paragraph.getText());
}
return content.toString();
}
- 替换指定字符:
public String replaceText(String content, String target, String replacement) {
return content.replace(target, replacement);
}
- 保存修改后的Word文件:
public void saveWordFile(XWPFDocument document, String filePath) {
try {
FileOutputStream fos = new FileOutputStream(filePath);
document.write(fos);
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
}
完整代码示例:
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.List;
public class WordUtils {
public static void main(String[] args) {
String filePath = "path/to/word/file.docx";
String target = "oldText";
String replacement = "newText";
XWPFDocument document = openWordFile(filePath);
String content = readWordFile(document);
String modifiedContent = replaceText(content, target, replacement);
saveWordFile(document, filePath);
}
public static XWPFDocument openWordFile(String filePath) {
try {
FileInputStream fis = new FileInputStream(filePath);
XWPFDocument document = new XWPFDocument(fis);
// 其他操作
fis.close();
return document;
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
public static String readWordFile(XWPFDocument document) {
StringBuilder content = new StringBuilder();
List<XWPFParagraph> paragraphs = document.getParagraphs();
for (XWPFParagraph paragraph : paragraphs) {
content.append(paragraph.getText());
}
return content.toString();
}
public static String replaceText(String content, String target, String replacement) {
return content.replace(target, replacement);
}
public static void saveWordFile(XWPFDocument document, String filePath) {
try {
FileOutputStream fos = new FileOutputStream(filePath);
document.write(fos);
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
以上代码使用Apache POI库来操作Word文件,其中openWordFile
方法用于打开Word文件,readWordFile
方法用于读取文件内容,replaceText
方法用于替换指定字符,saveWordFile
方法用于保存修改后的Word文件。
