hellointerceptor.java

这个是学习EJB的好例子,里面有许多关于EJB Bean的

package com.cws.ejb.hello;

import javax.interceptor.AroundInvoke;
import javax.interceptor.InvocationContext;

public class HelloInterceptor {

	@AroundInvoke
	public Object log(InvocationContext ctx) throws Exception {
		
		System.out.println("*** HelloInterceptor intercepting");
		
		long start = System.currentTimeMillis();
		ctx.proceed();
		long time = System.currentTimeMillis() - start;
		System.out.println("用时:" + time + "ms");		
		
		return null;
	}

}
