Constructor Detail
ConfigurableObjectInputStream
public ConfigurableObjectInputStream(InputStream in, @Nullable ClassLoader classLoader) throws IOException
Create a new ConfigurableObjectInputStream for the given InputStream and ClassLoader.- Parameters:
in- the InputStream to read fromclassLoader- the ClassLoader to use for loading local classes- Throws:
IOException- See Also:
ObjectInputStream(java.io.InputStream)
ConfigurableObjectInputStream
public ConfigurableObjectInputStream(InputStream in, @Nullable ClassLoader classLoader, boolean acceptProxyClasses) throws IOException
Create a new ConfigurableObjectInputStream for the given InputStream and ClassLoader.- Parameters:
in- the InputStream to read fromclassLoader- the ClassLoader to use for loading local classesacceptProxyClasses- whether to accept deserialization of proxy classes (may be deactivated as a security measure)- Throws:
IOException- See Also:
ObjectInputStream(java.io.InputStream)
Method Detail
resolveClass
protected Class<?> resolveClass(ObjectStreamClass classDesc) throws IOException, ClassNotFoundException
- Overrides:
resolveClassin classObjectInputStream- Throws:
IOExceptionClassNotFoundException
resolveProxyClass
protected Class<?> resolveProxyClass(String[] interfaces) throws IOException, ClassNotFoundException
- Overrides:
resolveProxyClassin classObjectInputStream- Throws:
IOExceptionClassNotFoundException
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.
- Parameters:
className- the class name to resolveex- the original exception thrown when attempting to load the class- Returns:
- the newly resolved class (never
null) - Throws:
IOExceptionClassNotFoundException
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.- Throws:
IOException
