1、想要使用redis先獲得連接池對象，及JedisPool
然后在配置生成連接池對象需要的參數咯
（1）你可以寫一個參數實體類，再寫一個bean注入到spring

@Component @ConfigurationProperties(prefix="redis")//這個在properties的配置文件里噢，框架是springboot，表示前綴是redis的，參數名稱得對應。 public class RedisConfig {private String host;private int port;private int timeout;//秒private String password;private int poolMaxTotal;private int poolMaxIdle;private int poolMaxWait;//秒public String getHost() {return host;}public void setHost(String host) {this.host = host;}public int getPort() {return port;}public void setPort(int port) {this.port = port;}public int getTimeout() {return timeout;}public void setTimeout(int timeout) {this.timeout = timeout;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public int getPoolMaxTotal() {return poolMaxTotal;}public void setPoolMaxTotal(int poolMaxTotal) {this.poolMaxTotal = poolMaxTotal;}public int getPoolMaxIdle() {return poolMaxIdle;}public void setPoolMaxIdle(int poolMaxIdle) {this.poolMaxIdle = poolMaxIdle;}public int getPoolMaxWait() {return poolMaxWait;}public void setPoolMaxWait(int poolMaxWait) {this.poolMaxWait = poolMaxWait;} } @Service public class RedisPoolFactory {@AutowiredRedisConfig redisConfig;@Beanpublic JedisPool JedisPoolFactory() {JedisPoolConfig poolConfig = new JedisPoolConfig();poolConfig.setMaxIdle(redisConfig.getPoolMaxIdle());poolConfig.setMaxTotal(redisConfig.getPoolMaxTotal());poolConfig.setMaxWaitMillis(redisConfig.getPoolMaxWait() * 1000);JedisPool jp = new JedisPool(poolConfig, redisConfig.getHost(), redisConfig.getPort(),redisConfig.getTimeout()*1000, redisConfig.getPassword(), 0);return jp;}}

（2）可以直接在開啟springmvc配置注解，直接配置
代碼如下

/*** 強指定redis的JedisPool接口構造函數，這樣才能在centos成功創建jedispool**/ public class JedisPoolWriper {/** Redis連接池對象 */private JedisPool jedisPool;public JedisPoolWriper(final JedisPoolConfig poolConfig, final String host,final int port) {try {jedisPool = new JedisPool(poolConfig, host, port);} catch (Exception e) {e.printStackTrace();}}/*** 獲取Redis連接池對象* @return*/public JedisPool getJedisPool() {return jedisPool;}/*** 注入Redis連接池對象* @param jedisPool*/public void setJedisPool(JedisPool jedisPool) {this.jedisPool = jedisPool;}} *** Ma.li.ran* 2017/11/17 0017 15:51* redis配置*/ @Configurationpublic class RedisConfiguration {@Value("${redis.hostname}")private String hostname;@Value("${redis.port}")private int port;@Value("${redis.pool.maxActive}")private int maxTotal;@Value("${redis.pool.maxIdle}")private int maxIdle;@Value("${redis.pool.maxWait}")private long maxWaitMillis;@Value("${redis.pool.testOnBorrow}")private boolean testOnBorrow;@Autowiredprivate JedisPoolConfig jedisPoolConfig;@Autowiredprivate JedisPoolWriper jedisPoolWriper;@Autowiredprivate JedisUtil jedisUtil;/*** 創建redis連接池的設置*/@Bean(name = "jedisPoolConfig")public JedisPoolConfig createJedisConfig() {JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();//控制一個pool可分配多少個jedis實例jedisPoolConfig.setMaxTotal(maxTotal);/*連接池中最多可空閑maxIdle個連接，這里取值為20，表示即使沒有數據庫連接依然可以空閑20個隨時等待待命*/jedisPoolConfig.setMaxIdle(maxIdle);//最大等待時間，當沒有可用鏈接時，連接池等待的最大歸還時間，超出拋出異常jedisPoolConfig.setMaxWaitMillis(maxWaitMillis);//在獲取連接時檢查有效性jedisPoolConfig.setTestOnBorrow(testOnBorrow);return jedisPoolConfig;}/*** 創建redis連接池*/@Bean(name = "jedisPool")public JedisPoolWriper createJedisPoolWriper() {JedisPoolWriper jedisPoolWriper = new JedisPoolWriper(jedisPoolConfig, hostname, port);return jedisPoolWriper;}/*** keys* @return*/@Bean(name = "jedisKeys")public JedisUtil.Keys createJedisKeys() {JedisUtil.Keys jedisKeys = jedisUtil.new Keys();return jedisKeys;}/*** Strings* @return*/@Bean(name = "jedisStrings")public JedisUtil.Strings createJedisStrings() {JedisUtil.Strings jedisStrings= jedisUtil.new Strings();return jedisStrings;}/*** Hash* @return*/@Bean(name = "jedisHash")public JedisUtil.Hash createJedisHash() {JedisUtil.Hash jedisHash= jedisUtil.new Hash();return jedisHash;}/*** Lists* @return*/@Bean(name = "jedisLists")public JedisUtil.Lists createJedisLists() {JedisUtil.Lists jedisLists= jedisUtil.new Lists();return jedisLists;}/*** Sets* @return*/@Bean(name = "jedisSets")public JedisUtil.Sets createJedisSets() {JedisUtil.Sets jedisSets= jedisUtil.new Sets();return jedisSets;}}

這樣連接池對象就能獲得了，然后就可以用里面的方法了。

2、
（1）用@Service管理起來直接使用，為了方便key值管理，定義一個key前綴接口

public interface KeyPrefix {public int expireSeconds();//過期時間public String getPrefix();//前綴 } public abstract class BasePrefix implements KeyPrefix{private int expireSeconds;private String prefix;public BasePrefix(String prefix) {//0代表永不過期this(0, prefix);}public BasePrefix( int expireSeconds, String prefix) {this.expireSeconds = expireSeconds;this.prefix = prefix;}public int expireSeconds() {//默認0代表永不過期return expireSeconds;}public String getPrefix() {String className = getClass().getSimpleName();return className+":" + prefix;}}

以后所有key都繼承這個base基類就好了，定義自己的key前綴和過期時間
然后定義一些基礎方法，方便業務使用
這里json處理用的fastjson

@Service public class RedisService {@AutowiredJedisPool jedisPool;/*** 獲取當個對象* */public <T> T get(KeyPrefix prefix, String key, Class<T> clazz) {Jedis jedis = null;try {jedis = jedisPool.getResource();//生成真正的keyString realKey = prefix.getPrefix() + key;String str = jedis.get(realKey);T t = stringToBean(str, clazz);return t;}finally {returnToPool(jedis);}}/*** 設置對象* */public <T> boolean set(KeyPrefix prefix, String key, T value) {Jedis jedis = null;try {jedis = jedisPool.getResource();String str = beanToString(value);if(str == null || str.length() <= 0) {return false;}//生成真正的keyString realKey = prefix.getPrefix() + key;int seconds = prefix.expireSeconds();if(seconds <= 0) {jedis.set(realKey, str);}else {jedis.setex(realKey, seconds, str);}return true;}finally {returnToPool(jedis);}}/*** 判斷key是否存在* */public <T> boolean exists(KeyPrefix prefix, String key) {Jedis jedis = null;try {jedis = jedisPool.getResource();//生成真正的keyString realKey = prefix.getPrefix() + key;return jedis.exists(realKey);}finally {returnToPool(jedis);}}/*** 刪除* */public boolean delete(KeyPrefix prefix, String key) {Jedis jedis = null;try {jedis = jedisPool.getResource();//生成真正的keyString realKey = prefix.getPrefix() + key;long ret = jedis.del(realKey);return ret > 0;}finally {returnToPool(jedis);}}/*** 增加值* */public <T> Long incr(KeyPrefix prefix, String key) {Jedis jedis = null;try {jedis = jedisPool.getResource();//生成真正的keyString realKey = prefix.getPrefix() + key;return jedis.incr(realKey);}finally {returnToPool(jedis);}}/*** 減少值* */public <T> Long decr(KeyPrefix prefix, String key) {Jedis jedis = null;try {jedis = jedisPool.getResource();//生成真正的keyString realKey = prefix.getPrefix() + key;return jedis.decr(realKey);}finally {returnToPool(jedis);}}public boolean delete(KeyPrefix prefix) {if(prefix == null) {return false;}List<String> keys = scanKeys(prefix.getPrefix());if(keys==null || keys.size() <= 0) {return true;}Jedis jedis = null;try {jedis = jedisPool.getResource();jedis.del(keys.toArray(new String[0]));return true;} catch (final Exception e) {e.printStackTrace();return false;} finally {if(jedis != null) {jedis.close();}}}public List<String> scanKeys(String key) {Jedis jedis = null;try {jedis = jedisPool.getResource();List<String> keys = new ArrayList<String>();String cursor = "0";ScanParams sp = new ScanParams();sp.match("*"+key+"*");sp.count(100);do{ScanResult<String> ret = jedis.scan(cursor, sp);List<String> result = ret.getResult();if(result!=null && result.size() > 0){keys.addAll(result);}//再處理cursorcursor = ret.getStringCursor();}while(!cursor.equals("0"));return keys;} finally {if (jedis != null) {jedis.close();}}}public static <T> String beanToString(T value) {if(value == null) {return null;}Class<?> clazz = value.getClass();if(clazz == int.class || clazz == Integer.class) {return ""+value;}else if(clazz == String.class) {return (String)value;}else if(clazz == long.class || clazz == Long.class) {return ""+value;}else {return JSON.toJSONString(value);}}@SuppressWarnings("unchecked")public static <T> T stringToBean(String str, Class<T> clazz) {if(str == null || str.length() <= 0 || clazz == null) {return null;}if(clazz == int.class || clazz == Integer.class) {return (T)Integer.valueOf(str);}else if(clazz == String.class) {return (T)str;}else if(clazz == long.class || clazz == Long.class) {return (T)Long.valueOf(str);}else {return JSON.toJavaObject(JSON.parseObject(str), clazz);}}private void returnToPool(Jedis jedis) {if(jedis != null) {jedis.close();}}}

使用時直接調用接口方法就好了，注意數據庫修改時及時同步緩存一致

這個工具類功能幾乎很全了，舉個栗子

// 定義redis的key前綴String key = PREFIX;// 定義接收對象List<User> user= null;// 定義jackson數據轉換操作類ObjectMapper mapper = new ObjectMapper();// 拼接出redis的keykey = key + "_" + user.getId();// 判斷key是否存在if (!jedisKeys.exists(key)) {// 若不存在，則從數據庫里面取出相應數據user= userDao.queryUser(user);// 將相關的實體類集合轉換成string,存入redis里面對應的key中String jsonString;jsonString = mapper.writeValueAsString(user);logger.error(e.getMessage());jedisStrings.set(key, jsonString);} else {// 若存在，則直接從redis里面取出相應數據String jsonString = jedisStrings.get(key);// 指定要將string轉換成的集合類型JavaType javaType = mapper.getTypeFactory().constructParametricType(String.class, User.class);// 將相關key對應的value里的的string轉換成對象的實體類集合user= mapper.readValue(jsonString, javaType);
