Apache tika是Apache开源的一个文档解析工具。Apache Tika可以解析和提取一千多种不同的文件类型(如PPT、XLS和PDF)的内容和格式,并且Apache Tika提供了多种使用方式,既可以使用图形化操作页面(tika-app),又可以独立部署(tika-server)通过接口调用,还可以引入到项目中使用。
本文演示在spring boot 中引入tika的方式解析文档。如下:
引入依赖
在spring boot 项目中引入如下依赖:
<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>
<dependency>
<groupId>org.apache.tika</groupId>
<artifactId>tika-core</artifactId>
</dependency>
<dependency>
<groupId>org.apache.tika</groupId>
<artifactId>tika-parsers-standard-package</artifactId>
</dependency>

创建配置
将tika-config.xml文件放在resources目录下。tika-config.xml文件的内容如下:
<?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>

Tika类中提供了文芳detect、translate和parse功能, 在项目中通过注入TIka, 就可以使用了
在项目使用
配置完成后在项目中可以通过注入TIka即可完成文档的解析。如下图所示:
