基于spring-date的已经实现了 CacheManager缓存管理器和caceh等，具体使用参考：http://blog.csdn.net/l_sail/article/details/70306339

工程结构

这里写图片描述

maven依赖

自定义缓存管理

package com.lf.redisConfig;import com.lf.config.RedisObjectSerializer;import org.springframework.cache.CacheManager;import org.springframework.cache.annotation.CachingConfigurerSupport;import org.springframework.cache.interceptor.KeyGenerator;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.data.redis.cache.RedisCacheManager;import org.springframework.data.redis.connection.RedisConnectionFactory;import org.springframework.data.redis.core.RedisTemplate;/** * Created by LF on 2017/4/20. */@Configurationpublic class RedisCacheConfig extends CachingConfigurerSupport {    @Bean    public CacheManager cacheManager(RedisTemplate<?, ?> redisTemplate) {        CacheManager cacheManager = new RedisCacheManager(redisTemplate);        return cacheManager;    }    @Bean    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {        RedisTemplate<String, String> redisTemplate = new RedisTemplate<String, String>();        redisTemplate.setConnectionFactory(factory);        //key序列化方式;（不然会出现乱码;）        //如果实现了key的自定义方式 方法上有Long等非String类型的话，会报类型转换错误；        //则要实现RedisSerializer的序列化，        redisTemplate.setKeySerializer(new RedisObjectSerializer());        redisTemplate.setValueSerializer(new RedisObjectSerializer());        return redisTemplate;    }    //自定义key的实现方式    @Override    public KeyGenerator keyGenerator() {        System.out.println("RedisCacheConfig.keyGenerator()");        return (o, method, objects) -> {            StringBuilder sb = new StringBuilder();            sb.append(o.getClass().getName());            sb.append(method.getName());            for (Object obj : objects) {                sb.append(obj.toString());            }            System.out.println("keyGenerator=" + sb.toString());            return sb.toString();        };    }}
