Java ClassLoaderObjectInputStream-class And Method Code Example
Here is an example of how to use the ClassLoaderObjectInputStream
class from the Apache Commons IO library in Java:
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import org.apache.commons.io.input.ClassLoaderObjectInputStream;
class Example {
public static void main(String[] args) {
byte[] data = ... // some serialized data
try (ObjectInputStream ois = new ClassLoaderObjectInputStream(
Example.class.getClassLoader(), new ByteArrayInputStream(data))) {
Object obj = ois.readObject();
// do something with obj
} catch (IOException | ClassNotFoundException e) {
// handle exception
}
}
}
This code creates a ClassLoaderObjectInputStream
using the current class's class loader and a ByteArrayInputStream containing the serialized data. The readObject method is then used to deserialize the object, and the object can be used as needed.
Note: The ClassLoaderObjectInputStream
is designed to be used in scenarios where the classloader of the current thread is not the same as the classloader that loaded the serialized classes. This can happen when working with container-based environments, such as JavaEE or OSGi.
