构造器详细资料

JarUrlClassLoader

public JarUrlClassLoader(URL[] urls,
 ClassLoader parent)

Create a new LaunchedClassLoader instance.

参数:

urls - the URLs from which to load classes and resources

parent - the parent class loader for delegation

方法详细资料

findResource

public URL findResource(String name)

覆盖:

findResource 在类中 URLClassLoader

findResources

public Enumeration<URL> findResources(String name)
                               throws IOException

覆盖:

findResources 在类中 URLClassLoader

抛出:

IOException

loadClass

protected Class<?> loadClass(String name,
 boolean resolve)
                      throws ClassNotFoundException

覆盖:

loadClass 在类中 ClassLoader

抛出:

ClassNotFoundException

definePackageIfNecessary

protected final void definePackageIfNecessary(String className)

Define a package before a findClass call is made. This is necessary to ensure that the appropriate manifest for nested JARs is associated with the package.

参数:

className - the class name being found

clearCache

public void clearCache()

Clear any caches. This method is called reflectively by ClearCachesApplicationListener.

close

public void close()
           throws IOException

指定者:

close 在接口中 AutoCloseable

指定者:

close 在接口中 Closeable

覆盖:

close 在类中 URLClassLoader

抛出:

IOException
