Apache tika -- 解析多种类型（word、pdf、txt 等）文件！
apache 是个伟大的组织。
在lucene 检索 如火如荼时， apache不忘继续努力，近期提供了对各种格式文件进行解析的解决方案 -- apache旗下的tika. 虽然还没有1.0版? ， 但已经很好用：
/** * 解析各种类型文件 * @param 文件路径 * @return 文件内容字符串 */public static String parse(String path) {String result = "";TikaConfig tikaConfig = TikaConfig.getDefaultConfig();try {result = ParseUtils.getStringContent(new File(path), tikaConfig);}catch (Exception e) {log.debug("[by ninja.hzw]" + e);}return result;}?
很简单，可以解析各种文件，返回文档内容字符串， word2003/2007 、 pdf? 、 txt 都经过测试，均能解析且无乱码问题。??

oh, Great Apach

Tika 的下载和打包：
下载不用多说，google 一下“apache tika” 找到其官网下载即可。
To build Tika from sources you first need to either download a source release or checkout the latest sources from version control.Once you have the sources, you can build them using the Maven 2 build system. Executing the following command in the base directory will build the sources and install the resulting artifacts in your local Maven repository.mvn install
?
apache 已经说得很清楚，进入下载后的tika 目录 ，然后执行maven install 即可。（当然这里需要您懂得maven2的使用。当然不会的朋友可以联系我^^ . 还需注意，必须为jdk1.5 + 才能成功编译打包。）
打包完后产生以下 jar：
tika-core/target/tika-core-0.7.jarTika core library. Contains the core interfaces and classes of Tika, but none of the parser implementations. Depends only on Java 5.tika-parsers/target/tika-parsers-0.7.jarTika parsers. Collection of classes that implement the Tika Parser interface based on various external parser libraries.tika-app/target/tika-app-0.7.jarTika application. Combines the above libraries and all the external parser libraries into a single runnable jar with a GUI and a command line interface.tika-bundle/target/tika-bundle-0.7.jarTika bundle. An OSGi bundle that includes everything you need to use all Tika functionality in an OSGi environment.
?
?我们要想做文档解析，只需引入tika-core 和 tika-parsers 即可。
?
当然如果您的项目是maven 构建的，那更好了。在pom里加上依赖：
<dependency> <groupId>org.apache.tika</groupId> <artifactId>tika-core</artifactId> <version>0.7</version> </dependency>
?
以及
<dependency> <groupId>org.apache.tika</groupId> <artifactId>tika-parsers</artifactId> <version>0.7</version> </dependency>
?
maven 会自动下载。（感谢maven官方的支持。）
1 楼 eidolonprince 2011-04-13 您好，我按照您给出的方法在lucene里使用了tika，现在有个问题，就是每次在解析pdf的时候，不报错，但是会给出一大堆信息，解析其他格式的时候都不存在这个问题，能否给我一些建议：
