# **Tika-内容分析工具包** #

官方网站：[https://tika.apache.org/][https_tika.apache.org]

在maven仓库下载最新版依赖 [https://mvnrepository.com/artifact/org.apache.tika/tika-parsers][https_mvnrepository.com_artifact_org.apache.tika_tika-parsers]

懒得去的同学，提供一个笔者正在使用的依赖

<dependency>
    	  <groupId>org.apache.tika</groupId>
    	  <artifactId>tika-parsers</artifactId>
    	  <version>1.18</version>
        </dependency>

> ### **提取url中的文字信息** ###

public class TikaDemo {
        public static void main(String[] args) throws IOException, TikaException {
            Tika tika = new Tika();
            String s = tika.parseToString(new URL("https://www.baidu.com"));
            System.out.println(s);
    
        }
    }
