spring 整合 redis

pom.xml 配置如下

    <!--Redis start -->         <dependency>           <groupId>org.springframework.data</groupId>           <artifactId>spring-data-redis</artifactId>           <version>1.6.1.RELEASE</version>         </dependency>         <dependency>           <groupId>redis.clients</groupId>           <artifactId>jedis</artifactId>           <version>2.7.3</version>         </dependency>         <!--Redis end --> 

redis.config 配置如下

#redis配置redis.host=222.128.4.xxredis.port=6379redis.password=xxxredis.maxIdle=100redis.maxActive=300redis.maxWait=1000redis.testOnBorrow=trueredis.timeout=100000

applicationContext.xml 配置如下

    <bean id="propertyConfigurer"        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">        <property name="locations">            <list>                <!-- 加载数据库配置 -->                <value>classpath:datasource.properties</value>                <!-- 加载redis数据库配置 -->                <value>classpath:redis.properties</value>            </list>        </property>    </bean>    <!-- 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 >   <!-- cache配置 -->  <bean id="redisUtil" class="user.cnwap.leshare.admin.util.RedisUtil" >      <property name="redisTemplate" ref="redisTemplate" />   </bean >

redisUtil.java 代码如下

/**  - redis cache 工具类  -  */public final class RedisUtil {   private Logger logger = Logger.getLogger(RedisUtil.class);   private RedisTemplate<Serializable, Object> redisTemplate;   /**  - 批量删除对应的value  -  - @param keys    */  public void remove(final String... keys) {     for (String key : keys) {       remove(key);     }   }   /**  - 批量删除key  -  - @param pattern    */  public void removePattern(final String pattern) {     Set<Serializable> keys = redisTemplate.keys(pattern);     if (keys.size() > 0)       redisTemplate.delete(keys);   }   /**  - 删除对应的value  -  - @param key    */  public void remove(final String key) {     if (exists(key)) {       redisTemplate.delete(key);     }   }   /**  - 判断缓存中是否有对应的value  -  - @param key  - @return    */  public boolean exists(final String key) {     return redisTemplate.hasKey(key);   }   /**  - 读取缓存  -  - @param key  - @return    */  public Object get(final String key) {     Object result = null;     ValueOperations<Serializable, Object> operations = redisTemplate         .opsForValue();     result = operations.get(key);     return result;   }   /**  - 写入缓存  -  - @param key  - @param value  - @return    */  public 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) {       e.printStackTrace();     }     return result;   }   /**  - 写入缓存  -  - @param key  - @param value  - @return    */  public 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;   }   public void setRedisTemplate(       RedisTemplate<Serializable, Object> redisTemplate) {     this.redisTemplate = redisTemplate;   } }

• 使用redis存取java对象，对象必须实现Serializable接口。
