Create tika-config.xml

<properties>
    <encodingDetectors>
        <encodingDetector class="org.apache.tika.parser.html.HtmlEncodingDetector">
            <params>
                <param name="markLimit" type="int">64000</param>
            </params>
        </encodingDetector>
        <encodingDetector class="org.apache.tika.parser.txt.UniversalEncodingDetector">
            <params>
                <param name="markLimit" type="int">64001</param>
            </params>
        </encodingDetector>
        <encodingDetector class="org.apache.tika.parser.txt.Icu4jEncodingDetector">
            <params>
                <param name="markLimit" type="int">64002</param>
            </params>

Define Configuration Class

import java.io.IOException;
import java.io.InputStream;
import org.apache.tika.Tika;
import org.apache.tika.config.TikaConfig;
import org.apache.tika.detect.Detector;
import org.apache.tika.exception.TikaException;
import org.apache.tika.parser.AutoDetectParser;
import org.apache.tika.parser.Parser;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.Resource;
import org.springframework.core.io.ResourceLoader;
import org.xml.sax.SAXException;

/** tika configuration class */
@Configuration
public class MyTikaConfig {
    @Autowired
    private ResourceLoader resourceLoader;

    @Bean
    public Tika tika() throws TikaException, IOException, SAXException {
        Resource resource = resourceLoader.getResource("classpath:tika-config.xml");
        InputStream inputStream = resource.getInputStream();
        TikaConfig config = new TikaConfig(inputStream);
        Detector detector = config.getDetector();
        Parser autoDetectParser = new AutoDetectParser(config);
        return new Tika(detector, autoDetectParser);
    }
}

Use Tika Bean in Your Application

After the configuration is in place, inject the Tika bean wherever you need to process documents. The bean provides detect, parse, and translate methods to handle a wide range of file formats such as PDF, PPT, XLS, and more.
