redis缓存与删除SpringAOP方式，支持SpringEl表达式

【前置条件】
1.maven关键依赖：

	org.springframework.data
	spring-data-redis
	1.7.1.RELEASE


	org.springframework
	spring-expression
	4.2.6.RELEASE

2.redis.properties文件配置：

# redis  #
redis.cache.pool.maxTotal=100
redis.cache.pool.maxIdle=5
redis.cache.pool.maxWaitMillis=1000
redis.cache.pool.testOnBorrow=true
redis.cache.usePool=true

redis.cluster.password=
redis.cluster.timeout=6000

# redis cluster ip  #
clusterHostAndPorts[0]=10.11.12.247:6380
clusterHostAndPorts[1]=10.11.12.247:6380
clusterHostAndPorts[2]=10.11.12.247:6380
clusterHostAndPorts[3]=10.11.12.247:6380
clusterHostAndPorts[4]=10.11.12.247:6380
clusterHostAndPorts[5]=10.11.12.247:6380

3.spring启动注入类：

package com.bbs.redis.util;

import java.util.Map;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.NoSuchBeanDefinitionException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class ApplicationContextBean implements ApplicationContextAware {
    private static ApplicationContext applicationContext;

    public ApplicationContextBeans() {
    }

    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        applicationContext = applicationContext;
    }

    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

    public static Object getBean(String name) throws BeansException {
        return applicationContext.getBean(name);
    }

    public static Object getBean(String name, Class requiredType) throws BeansException {
        return applicationContext.getBean(name, requiredType);
    }

    public static boolean containsBean(String name) {
        return applicationContext.containsBean(name);
    }

    public static boolean isSingleton(String name) throws NoSuchBeanDefinitionException {
        return applicationContext.isSingleton(name);
    }

    public static Class getType(String name) throws NoSuchBeanDefinitionException {
        return applicationContext.getType(name);
    }

    public static String[] getAliases(String name) throws NoSuchBeanDefinitionException {
        return applicationContext.getAliases(name);
    }

    public static  T getBean(Class requiredType) throws BeansException {
        return applicationContext.getBean(requiredType);
    }

    public static  Map getBeansOfType(Class type) throws BeansException {
        return applicationContext.getBeansOfType(type);
    }
}

4.SerializeUtil序列化类：

package com.bbs.redis.util.SerializeUtil;

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.SerializationException;

public class SerializeUtil implements RedisSerializer
