先说以下需要加入的jar,maven

<dependency>
                <groupId>redis.clients</groupId>
                <artifactId>jedis</artifactId>
                <version>2.9.0</version>
            </dependency>
            
            <dependency>
                <groupId>com.dyuproject.protostuff</groupId>
                <artifactId>protostuff-core</artifactId>
                <version>1.0.8</version>
            </dependency>
            <dependency>
                <groupId>org.springframework.data</groupId>
                <artifactId>spring-data-redis</artifactId>
                <version>1.7.2.RELEASE</version>
            </dependency>

属性文件的配置

address1=192.168.63.129:7001
    address2=192.168.63.129:7002
    address3=192.168.63.129:7003
    address4=192.168.63.129:7004
    address5=192.168.63.129:7005
    address6=192.168.63.129:7006
    #客户端超时时间单位是毫秒
    redis.timeout=300000
    #最大连接数
    redis.maxActive=1024
    #最小空闲数
    redis.minIdle=8
    #最大空闲数
    redis.maxIdle=100
    #最大建立连接等待时间
    redis.maxWaitMillis=1000
    #redis集群单位数
    redis.maxRedirections=6
    #这里和你的redis数据库个数一样
    redis.testOnBorrow=true

Spring-redis.xml文件的配置

一个工厂类

                    if(((String)key).startsWith(this.addressKeyPrefix)) {

一个序列化工具类

package com.cn.dlnu.common.utils;
    
    import java.io.ByteArrayInputStream;
    import java.io.ByteArrayOutputStream;
    import java.io.ObjectInputStream;
    import java.io.ObjectOutputStream;
    /** * @version V1.0 * @Description: * @Modified By:Ming Created in 23:14 2017/1/10 */
    public class SerializerUtil { 
    
        /** * 序列化 * @param object * @return */
        public static byte[] serializeObj(Object object) {
            ObjectOutputStream oos = null;
            ByteArrayOutputStream baos = null;
            try {
                baos = new ByteArrayOutputStream();
                oos = new ObjectOutputStream(baos);
                oos.writeObject(object);
                byte[] bytes = baos.toByteArray();
                return bytes;
            } catch (Exception e) {
                throw new RuntimeException("序列化失败!", e);
            }
        }
    
        /** * 反序列化 * @param bytes * @return */
        public static Object deserializeObj(byte[] bytes) {
            if (bytes == null){
                return null;
            }
            ByteArrayInputStream bais = null;
            try {
                bais = new ByteArrayInputStream(bytes);
                ObjectInputStream ois = new ObjectInputStream(bais);
                return ois.readObject();
            } catch (Exception e) {
                throw new RuntimeException("反序列化失败!", e);
            }
        }
    }

最后一个测试类

package com.cn.dlnu.dao.cache;
    
    import com.cn.dlnu.MetendMethod;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    
    import javax.annotation.Resource;
    import java.util.ArrayList;
    import java.util.HashMap;
    import java.util.List;
    import java.util.Map;
    
    /** * RedisCache Tester. * * @author <Authors name> * @version 1.0 * @since <pre>01/10/2017</pre> */
    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(locations = {
       "classpath:spring/spring-applicationContext.xml", "classpath:/spring/spring-redis.xml"})
    public class RedisCacheTest { 
    
        @Resource
        private RedisCache redisCache;
    
        /** * Method: putCache(String key, T obj) */
        @Test
        public void testPutCache() throws Exception {
            List<String> list = new ArrayList<>();
            list.add("测试list");
            list.add("测试list2");
            redisCache.putCache("testList","redis集群测试");
            redisCache.putCache("name","123123");
            Map<String,Object> map = new HashMap<String, Object>();
            map.put("test*","测试数据");
            map.put("测试数据","啥的");
            map.put("listTest",list);
            redisCache.putCache("testMap",map);
    
            redisCache.putCache("testString","redis集群测试");
            Map resultMap = new HashMap();
            resultMap.put("testList",redisCache.getCache("testList"));
            resultMap.put("testMap",redisCache.getCache("testMap"));
            resultMap.put("testString",redisCache.getCache("testString"));
            System.out.print(map);
        }
    
        /** * Method: putCacheWithExpireTime(String key, T obj, final int expireTime) */
        @Test
        public void testPutCacheWithExpireTime() throws Exception {
    
        }
    
        /** * Method: getCache(final String key) */
        @Test
        public void testGetCache() throws Exception {
            System.out.println(redisCache.getCache("name").toString());
        }
    }
