Apache-Tika解析JPEG文档

package com.mengyao.tika.app;

import java.io.File;
import java.io.FileInputStream;

import org.apache.tika.metadata.Metadata;
import org.apache.tika.parser.ParseContext;
import org.apache.tika.parser.jpeg.JpegParser;
import org.apache.tika.sax.BodyContentHandler;

public class JpegApp {

    public static void main(final String[] args) throws Exception {
        // Tika默认是10*1024*1024，这里防止文件过大导致Tika报错
        BodyContentHandler handler = new BodyContentHandler(1024 * 1024 * 10);
        Metadata metadata = new Metadata();
        FileInputStream inputstream = new FileInputStream(new File("D:/无标题.jpg"));
        ParseContext pcontext = new ParseContext();

        // 解析JPEG文件时应由超类AbstractParser的派生类JpegParser实现
        JpegParser msofficeparser = new JpegParser();
        msofficeparser.parse(inputstream, handler, metadata, pcontext);
        // 获取JPEG文件的内容
        System.out.println("JPEG文件内容:" + handler.toString());

        // 获取JPEG文件的元数据
        System.out.println("JPEG文件元数据:");
        String[] metadataNames = metadata.names();

        for (String name : metadataNames) {
            System.out.println(name + " : " + metadata.get(name));
        }
    }

}

方法2：

public String tikaTool(File f){  
        Tika tika=new Tika();  
        try  
        {  
            return tika.parseToString(f);  
        }  
        catch (IOException e)  
        {  
              
            e.printStackTrace();  
        }  
        catch (TikaException e)  
        {  
              
            e.printStackTrace();  
        }  
        return null;  
    }
