一、添加Redis Maven依赖
<!-- redis --> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.6.2</version> </dependency> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-redis</artifactId> <version>1.7.1.RELEASE</version> </dependency>二、config.properties redis.host=192.168.0.254 redis.port=6379 redis.password=jedis21tb redis.maxIdle=300 redis.maxWait=1000 redis.testOnBorrow=true redis.timeout=3000 三、spring配置文件(applicationContext.xml)： <!--引入配置属性文件 --> <context:property-placeholder location="classpath:config.properties" /> <!-- redis --> <!-- jedis 配置 --> <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig" > <property name="maxIdle" value="${redis.maxIdle}" /> <property name="maxWaitMillis" value="${redis.maxWait}" /> <property name="testOnBorrow" value="${redis.testOnBorrow}" /> </bean > <!-- redis服务器中心 --> <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" > <property name="poolConfig" ref="poolConfig" /> <property name="port" value="${redis.port}" /> <property name="hostName" value="${redis.host}" /> <property name="password" value="${redis.password}" /> <property name="timeout" value="${redis.timeout}" ></property> </bean > <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate" > <property name="connectionFactory" ref="connectionFactory" /> <property name="keySerializer" > <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" /> </property> <!-- <property name="valueSerializer" > <bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" /> </property> --> </bean > <bean id="redisUtil" class="com.kttx.common.RedisUtil" > <property name="redisTemplate" ref="redisTemplate" /> </bean >四、java代码 package com.kttx.common; import java.io.Serializable; import java.util.Set; import java.util.concurrent.TimeUnit; import org.apache.log4j.Logger; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.core.ValueOperations; /** * redis * @author txs * */ public class RedisUtil { private static Logger logger = Logger.getLogger(RedisUtil.class); private static RedisTemplate<Serializable, Object> redisTemplate; /** * 写入或更新缓存 * @param key * @param value * @return */ public static boolean set(final String key, Object value) { boolean result = false; try { ValueOperations<Serializable, Object> operations = redisTemplate .opsForValue(); operations.set(key, value); result = true; } catch (Exception e) { logger.error("write redis is faill"); e.printStackTrace(); } return result; } /** * 写入缓存 * 设置失效时间 * @param key * @param value * @return */ public static boolean set(final String key, Object value, Long expireTime) { boolean result = false; try { ValueOperations<Serializable, Object> operations = redisTemplate .opsForValue(); operations.set(key, value); redisTemplate.expire(key, expireTime, TimeUnit.SECONDS); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } /** * 读取缓存 * @param key * @return */ public static Object get(final String key) { Object result = null; ValueOperations<Serializable, Object> operations = redisTemplate .opsForValue(); result = operations.get(key); return result; } /** * 删除对应的value * @param key */ public static void remove(final String key) { if (exists(key)) { redisTemplate.delete(key); } } /** * 批量删除对应的value * * @param keys */ public static void remove(final String... keys) { for (String key : keys) { remove(key); } } /** * 批量删除key * * @param pattern 正则表达式 */ public static void removePattern(final String pattern) { Set<Serializable> keys = redisTemplate.keys(pattern); if (keys.size() > 0) redisTemplate.delete(keys); } /** * 判断缓存中是否有对应的value * * @param key * @return */ public static boolean exists(final String key) { return redisTemplate.hasKey(key); } public void setRedisTemplate( RedisTemplate<Serializable, Object> redisTemplate) { this.redisTemplate = redisTemplate; } } 使用：RedisUtil.set(key,value);
