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> php </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> PGNST </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.jsBean; 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; impo编程客栈rt org.apache.tika.Tika; import org.apa编程客栈che.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); } }
