ConfigurableObjectInputStream

public ConfigurableObjectInputStream(InputStream in,
 @Nullable
 ClassLoader classLoader)
                              throws IOException

Create a new ConfigurableObjectInputStream for the given InputStream and ClassLoader.

参数:

in - the InputStream to read from

classLoader - the ClassLoader to use for loading local classes

抛出:

IOException

ConfigurableObjectInputStream

public ConfigurableObjectInputStream(InputStream in,
 @Nullable
 ClassLoader classLoader,
 boolean acceptProxyClasses)
                              throws IOException

Create a new ConfigurableObjectInputStream for the given InputStream and ClassLoader.

参数:

in - the InputStream to read from

classLoader - the ClassLoader to use for loading local classes

acceptProxyClasses - whether to accept deserialization of proxy classes (may be deactivated as a security measure)

抛出:

IOException

方法详细资料

resolveClass

protected Class<?> resolveClass(ObjectStreamClass classDesc)
                         throws IOException,
ClassNotFoundException

覆盖:

resolveClass 在类中 ObjectInputStream

抛出:

IOException

ClassNotFoundException

resolveProxyClass

protected Class<?> resolveProxyClass(String[] interfaces)
                              throws IOException,
ClassNotFoundException

覆盖:

resolveProxyClass 在类中 ObjectInputStream

抛出:

IOException

ClassNotFoundException

resolveFallbackIfPossible

protected Class<?> resolveFallbackIfPossible(String className,
 ClassNotFoundException ex)
                                      throws IOException,
ClassNotFoundException

Resolve the given class name against a fallback class loader.

The default implementation simply rethrows the original exception, since there is no fallback available.

参数:

className - the class name to resolve

ex - the original exception thrown when attempting to load the class

返回:

the newly resolved class (never null)

抛出:

IOException

ClassNotFoundException

getFallbackClassLoader

@Nullable
protected ClassLoader getFallbackClassLoader()
                                      throws IOException

Return the fallback ClassLoader to use when no ClassLoader was specified and ObjectInputStream's own default class loader failed.

The default implementation simply returns null, indicating that no specific fallback is available.

抛出:

IOException
