java.lang.Object
- java.util.zip.ZipFile
- - java.util.jar.JarFile
  - - org.springframework.boot.loader.jar.JarFile

所有已实现的接口:
Closeable, AutoCloseable
```
public class JarFile
extends JarFile
```
Extended variant of JarFile that behaves in the same way but offers the following additional functionality.
- A nested JarFile can be obtained based on any directory entry.
- A nested JarFile can be obtained for embedded JAR files (as long as their entry is not compressed).
