使用CGLIB生成代理

CGLIB能够生成目标类的子类，并重写父类非final修饰符的方法。

 

//实现methid
public class CGLIBProxy2 implements MethodInterceptor {

	// 目标类对象
	private Object targetObject;

	// 根据目标类对象建立代理子类
	public Object createProxyObject(Object obj) {
		targetObject = obj;
		Enhancer enhancer = new Enhancer();
		enhancer.setSuperclass(obj.getClass());
		enhancer.setCallback(this);
		return enhancer.create();
	}

	@Override
	public Object intercept(Object arg0, Method arg1, Object[] arg2, MethodProxy arg3) throws Throwable {
		System.out.println("1");
		Object o = arg3.invoke(targetObject, arg2);
		System.out.println("2");
		return o;

	}

}
