Java 经过ReflectionFactory 创建序列化的实例(原创)

import java.io.Serializable;

public class Foo implements Serializable {
	private String str;
	public Foo(String str) {
		this.str = str;
	}
}

 Foo是一个可以序列化的实体类

public class FooTest {
	private static final ReflectionFactory REFLECTION_FACTORY = ReflectionFactory.getReflectionFactory();
	
	public static void main(String[] args)  {
		Class<Foo> clazz = Foo.class;
		try {
			Foo foo = newSerializableInstance(clazz);
		} catch (InvocationTargetException e) {
			
		}
	}
	
	public static <T> T newSerializableInstance(Class<T> clazz) throws InvocationTargetException {
		Class<?> cl = clazz;
		while(Serializable.class.isAssignableFrom(cl)) {
			if ((cl = cl.getSuperclass()) == null) {
				return null;
			}
		}
		try {
			Constructor<?> cons = cl.getDeclaredConstructor((Class<?>[]) null);
			cons = REFLECTION_FACTORY.newConstructorForSerialization(clazz, cons);
			cons.setAccessible(true);
			return (T)cons.newInstance();
		} catch (NoSuchMethodException e) {
			return null;
		} catch (InstantiationException e) {
			return null;
		} catch (IllegalAccessException e) {
			return null;
		} catch (IllegalArgumentException e) {
			return null;
		}
	}
}
