在 Netbeans 8.0.2 和 Java 8 中使用 Apache Tika 1.9 会产生巨大的可执行文件.怎么做才能缩小尺寸? [英] Using Apache Tika 1.9 in Netbeans 8.0.2 and Java 8 produces HUGE executable. What to do to reduce size?
问题描述
我在使用外部库方面运气不佳，所以我只是在任何使用实用程序的项目中包含了实用程序的源代码.
I haven't had much luck with external libraries, so I've just included the source for utilities in any project that uses utilities.
现在我有一个需要 Apache Tika 的项目，所以我必须有一个类似这样的库设置:
Now I have a project that requires Apache Tika, so I have to have a library setup something like this:
但是要从 Netbeans 外部运行程序，我显然(根据 dist 文件夹中的 readme.txt)需要压缩 .jar 和 lib 文件夹，解压缩该压缩文件，提取内容，然后从提取到的任何位置运行.
But to run the program from outside Netbeans, I apparently (per readme.txt in dist folder) need to zip the .jar and lib folder, unzip that zipped file, extract the contents, and run from wherever it's extracted to.
但 Tika 库是 45MB.
But the Tika lib is 45MB.
我只使用了 tika-app-1.9.jar 库文件中的 5 个对象:
I only use 5 objects from the tika-app-1.9.jar library file:
import org.apache.tika.exception.TikaException;
import org.apache.tika.metadata.Metadata;
import org.apache.tika.mime.MimeTypeException;
import org.apache.tika.parser.AutoDetectParser;
import org.apache.tika.sax.BodyContentHandler;
如何将一小部分 Tika 对象制作成一个比 45MB 小很多的库?
How do I make a tiny subset of Tika objects into a library that will be a lot smaller than 45MB?
还是我错过了我应该做的重点?
Or am I missing the point of what I SHOULD do?
推荐答案
你应该只包含 tika-core 和 tika-parsers 组件，这两个文件应该是不超过 1.2MB.
You should only include the tika-core and tika-parsers components, these two files should be no more than 1.2MB.
tika-app jar 在主页上是这样描述的:
The tika-app jar is described on the home page as this:
Tika 应用程序. 将上述组件和所有外部解析器库组合成一个带有 GUI 和命令行界面的可运行 jar.
Tika application. Combines the above components and all the external parser libraries into a single runnable jar with a GUI and a command line interface.
所以它有很多你的应用不需要的额外东西.
So it has a lot of extra things, which your app does not need.
