CGLIB Sample

It's very simple sample for CGLib Proxy being used by Spring.

	public static void main(String[] args) {
	    Enhancer enhancer = new Enhancer();
	    // enhancer.setSuperclass(MemberServiceImpl.class);
	    enhancer.setSuperclass(MemberService.class);
	    enhancer.setCallback(new MethodCallLogInterceptor());
	    Object obj = enhancer.create();
	    MemberService memberService = (MemberService)obj;
	    memberService.regist(new Member());
	}

public class MethodCallLogInterceptor implements MethodInterceptor {
	
	MemberService memberService = new MemberServiceImpl();
    
    public Object intercept(Object object, Method method, Object[] args, 
            MethodProxy methodProxy) throws Throwable {
        System.out.println("before ");
        
        // Object returnValue = methodProxy.invokeSuper(memberService, args);
        Object returnValue = method.invoke(memberService, args);
        
        System.out.println("after ");
        return returnValue;
    }
}
