有没有一种简单的方法，通过 Java 库或第三方库来压缩 Java 中的现有文件？
我已经熟悉创建 ZipOutputStream、向其添加 ZipEntry 对象，然后将数据从流读取到 ZipOutputStream 的方法，我正在寻找一种更简单的方法来压缩一个文件。这很可能是对第三方压缩库的推荐。
Is there a simple way, either through the Java libraries or a third party library to zip an existing file in Java?
I am already familiar with the approach of creating a ZipOutputStream, adding ZipEntry objects to that, and then reading the data from a stream into the ZipOutputStream, I'm looking for a simpler way to zip up one File. Most likely this is going to be a recommendation for a third party compression library.

Apache Cayenne 项目有一个非常简单的 ZipUtil，您可以在此处查看 javadoc：
http://cayenne.apache.org/doc20/api/cayenne/org/apache/cayenne/util/ZipUtil.html
查看源代码，它仅从 Java 导入SDK，因此应该很容易放入您的应用程序中：
http://svn.apache.org/repos/asf/cayenne/main/branches/cayenne-jdk1.5-generics -unpublished/src/main/java/org/apache/cayenne/util/ZipUtil.java
The Apache Cayenne project has a pretty simple ZipUtil, you can check out the javadoc here:

Looking at the source it only has imports from the Java SDK so it should be easy to just drop into your application:
