JAVA实现word和pdf的数据解析(图片，表格等)转HTML存储以及海量搜索

这篇文章距离上次修改已过189天，其中的内容可能已经有所变动。

要在Java中实现Word和PDF数据的解析，并将其转换为HTML并存储以便进行海量搜索，可以使用Apache POI库解析Word文档和Apache PDFBox库解析PDF。以下是一个简化的例子：

添加依赖到你的项目中（使用Maven）：




<!-- Apache POI -->
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>YOUR_POI_VERSION</version>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>YOUR_POI_VERSION</version>
</dependency>
<!-- Apache PDFBox -->
<dependency>
    <groupId>org.apache.pdfbox</groupId>
    <artifactId>pdfbox</artifactId>
    <version>YOUR_PDFBOX_VERSION</version>
</dependency>

实现Word和PDF到HTML的转换：




import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.text.PDFTextStripper;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
 
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.util.List;
 
public class DocToHtmlConverter {
 
    public static void main(String[] args) throws Exception {
        convertWordToHtml("example.docx", "example.html");
        convertPdfToHtml("example.pdf", "example.html");
    }
 
    public static void convertWordToHtml(String docFile, String htmlFile) throws Exception {
        FileInputStream fis = new FileInputStream(new File(docFile));
        XWPFDocument document = new XWPFDocument(fis);
        List<XWPFParagraph> paragraphs = document.getParagraphs();
 
        StringBuilder htmlBuilder = new StringBuilder("<html><body>");
        for (XWPFParagraph para : paragraphs) {
            htmlBuilder.append("<p>").append(para.getText()).append("</p>");
        }
        htmlBuilder.append("</body></html>");
 
        Writer writer = new OutputStreamWriter(new FileOutputStream(htmlFile), "UTF-8");
        writer.write(htmlBuilder.toString());
        writer.close();
    }
 
    public static void convertPdfToHtml(String pdfFile, String htmlFile) throws Exception {
        PDDocument document = PDDocument.load(new File(pdfFile));
        PDFTextStripper stripper = new PDFTextStripper();
        String text = stripper.getText(document);
 
        StringBuilder htmlBuilder = new StringBuilder("<html><body>");
        htmlBuilder.append(text);
        htmlBuilder.append("</body></html>");
 
        Wr
