Annotation实现缓存,Bean指定代码缓存类

	<!-- Ehcache拦截，使用代理来实现 -->
	<bean id="beanPostProcessor" class="org.frame.base.annotation.support.EhCacheBeanPostProcessor" >
		<property name="beans">
			 <set>
			 	<value>testI</value>
			 	<value>intabc</value>
			 </set>
		</property>
	</bean>

package org.frame.base.annotation.support;

import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Proxy;
import java.util.Set;

import org.frame.base.annotation.intercept.ProxyHandler;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.BeanPostProcessor;

/**
 * 使用Ehcache代理来实现缓存拦截 
 *
 */
public class EhCacheBeanPostProcessor implements BeanPostProcessor{

	private Set<String> beans;

	public void setBeans(Set<String>  beans) {
		this.beans = beans;
	}

	@Override
	public Object postProcessAfterInitialization(Object target, String beanName)
			throws BeansException { 
		return target;
	}

	/**
	 * will be process the beans define in properties
	 * if you don't want to define
	 * you can define the pach model  *DAO
	 * you can define the pach model  *Service
	 * you can define the pach model  *Action
	 * but i sugguest you define
	 */
	@Override
	public Object postProcessBeforeInitialization(Object target, String beanName)
			throws BeansException {
		if(beans.contains(beanName)){
			Class<?>[] interfaceClass = target.getClass().getInterfaces();
			InvocationHandler handler = new ProxyHandler(target);
			Object proxyObj = Proxy.newProxyInstance(target.getClass().getClassLoader(),
					interfaceClass, handler);
			return proxyObj;
		}else{
			return target;
		}

	} 
}

指定代理的类，这样去除缓存很简单，代码不需要更改，只需要从拦截的beans设置里面去掉该beanName，缓存就没了，添加只需要添加该bean定义。
