Apache tika 实现各种文档内容解析

1、依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>cn.js</groupId>
    <artifactId>TikaResouce</artifactId>
    <version>1.0-SNAPSHOT</version>
    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.7.0</version>
    </parent>
        <dependencyManagement>
            <dependencies>
                <dependency>
                    <groupId>org.apache.tika</groupId>
                    <artifactId>tika-bom</artifactId>
                    <version>2.8.0</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
        </dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>commons-fileupload</groupId>
            <artifactId>commons-fileupload</artifactId>
            <version>1.4</version>
        </dependency>
        <dependency>
            <groupId>org.apache.tika</groupId>
            <artifactId>tika-core</artifactId>
        </dependency>
        <dependency>
            <groupId>org.apache.tika</groupId>
            <artifactId>tika-parsers-standard-package</artifactId>
        </dependency>
    </dependencies>
</project>

2、配置文件

新建一个 tika-config.xml 文件

<?xml version="1.0" encoding="UTF-8"?>
<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>
        </encodingDetector>
    </encodingDetectors>
</properties>

3、配置类

package cn.js.config;
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配置类
 */
@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);
    }
}

controller

package cn.js.controller;
import org.apache.tika.Tika;
import org.apache.tika.exception.TikaException;
import org.springframework.http.HttpRequest;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
import javax.annotation.Resource;
import java.io.IOException;
import java.io.InputStream;
@RestController
@RequestMapping("/tika")
public class TikaController {
    @Resource
    private Tika tika;
    @PostMapping("/pdf")
    public void TikaDemon(@RequestParam("file") MultipartFile file) throws IOException, TikaException {
        InputStream inputStream = file.getInputStream();
        String s = tika.parseToString(inputStream);
        System.out.println(s);
    }
}
