这是项目结构

RedisCacheConfig

package com.ssm.promotion.core.redis;


import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.annotation.EnableCaching;
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.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;


/**
 * Created by 13 on 2017/12/4.
 */
@Component
@EnableCaching
@Configuration
public class RedisCacheConfig extends CachingConfigurerSupport {

    @Bean
    public JedisConnectionFactory redisConnectionFactory() {
        JedisConnectionFactory redisConnectionFactory = new JedisConnectionFactory();
        //ip地址
        redisConnectionFactory.setHostName("127.0.0.1");
        //端口号
        redisConnectionFactory.setPort(6379);
        //redis登录密码
        redisConnectionFactory.setPassword("");
        //database 默认是16个，不设置的话默认为0
        redisConnectionFactory.setDatabase(2);
        return redisConnectionFactory;
    }

    @Bean
    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory cf) {
        RedisTemplate<String, String> redisTemplate = new RedisTemplate<String, String>();
        redisTemplate.setConnectionFactory(cf);
        return redisTemplate;
    }

    @Bean
    public CacheManager cacheManager(RedisTemplate redisTemplate) {
        RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate);
        //默认过期时间
        cacheManager.setDefaultExpiration(3000);
        return cacheManager;
    }

}

RedisUtil

package com.ssm.promotion.core.redis;

import org.springframework.data.redis.cache.RedisCache;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;

/**
 * Created by 13 on 2017/12/4.
 */
@Component
public class RedisUtil {

    private static final String CACHE_NAME = "perfect-ssm-cache:";
    // 过期时间
    private static final int EXPIRE_TIME = 3000;

    private RedisTemplate template;

    private RedisCache cache;

    public RedisUtil() {
        init();
    }

    public void init() {
        template = SpringUtil.getBean("redisTemplate");//RedisCacheConfig中定义了
        cache = new RedisCache(CACHE_NAME, CACHE_NAME.getBytes(), template, EXPIRE_TIME);
    }

    public void put(String key, Object obj) {
        cache.put(key, obj);
    }

    public Object get(String key, Class clazz) {
        return cache.get(key) == null ? null : cache.get(key, clazz);
    }

    public void del(String key) {
        cache.evict(key);
    }
}
