Spring 集成 Redis

1、利用spring-data-redis整合

<dependencies>     <dependency>          <groupId>org.springframework.data</groupId>          <artifactId>spring-data-redis</artifactId>          <version>1.0.2.RELEASE</version>      </dependency>      <dependency>          <groupId>org.springframework</groupId>          <artifactId>spring-core</artifactId>          <version>3.1.2.RELEASE</version>      </dependency>            <dependency>          <groupId>redis.clients</groupId>          <artifactId>jedis</artifactId>          <version>2.1.0</version>      </dependency>             <dependency>          <groupId>junit</groupId>          <artifactId>junit</artifactId>          <version>4.8.2</version>          <scope>test</scope>      </dependency>                  <dependency>                <groupId>org.slf4j</groupId>                <artifactId>slf4j-api</artifactId>                <version>1.6.1</version>            </dependency>            <!-- 将现有的jakarta commons logging的调用转换成lsf4j的调用。 -->            <dependency>                <groupId>org.slf4j</groupId>                <artifactId>jcl-over-slf4j</artifactId>                <version>1.6.1</version>            </dependency>            <!-- Hack：确保commons-logging的jar包不被引入，否则将和jcl-over-slf4j冲突 -->            <dependency>                <groupId>commons-logging</groupId>                <artifactId>commons-logging</artifactId>                <version>1.1.1</version>                <scope>provided</scope>            </dependency>            <!-- slf4j的实现：logback，用来取代log4j。更快、更强！ -->            <dependency>                <groupId>ch.qos.logback</groupId>                <artifactId>logback-classic</artifactId>                <version>0.9.24</version>                <scope>runtime</scope>            </dependency>  </dependencies>

2、applicationContext.xml

<!-- 启用注解 --><context:annotation-config /> <!-- 启动组件扫描，排除@Controller组件，该组件由SpringMVC配置文件扫描 --><context:component-scan base-package="com.jmust.weixin">        <context:exclude-filter type="annotation"                                        expression="org.springframework.stereotype.Controller" /></context:component-scan>     <!-- 引入配置文件 --><bean id="propertyConfigurer"  class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">        <property name="locations">              <list>                  <value>classpath:redis.properties</value>            </list>          </property> </bean><!-- redis --><bean id="jedisShardInfo" class="redis.clients.jedis.JedisShardInfo" >        <constructor-arg  value="${redis.host}"/>        <constructor-arg  value="${redis.port}"/>        <constructor-arg  value="${redis.pass}"/>    </bean>    <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">        <property name="shardInfo" ref="jedisShardInfo"/> </bean><bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">          <property name="connectionFactory"   ref="connectionFactory" /></bean>

3、redis.properties

# Redis settings  redis.host=192.168.1.41  redis.port=6379  redis.pass=123456      redis.maxIdle=300  redis.maxActive=600  redis.maxWait=1000  redis.testOnBorrow=true

4、RedisServiceImpl.java

@Servicepublic class RedisServiceImpl {    static final String wx_return_url = "wx_return_url";        @Resource    protected RedisTemplate<Serializable, Serializable> redisTemplate;    /**     *      * @param token     * @param value     */    public void set(final String token, final String value) {        redisTemplate.execute(new RedisCallback<Object>() {            @Override            public Object doInRedis(RedisConnection connection) throws DataAccessException {                RedisSerializer<String> redisSerializer = redisTemplate.getStringSerializer();                connection.hSet(redisSerializer.serialize(wx_return_url), redisSerializer.serialize(token),                        redisSerializer.serialize(value));                return null;            }        });    }    /**     *      * @param token     * @return     */    public String get(final String token) {        return redisTemplate.execute(new RedisCallback<String>() {            @Override            public String doInRedis(RedisConnection connection) throws DataAccessException {                RedisSerializer<String> redisSerializer = redisTemplate.getStringSerializer();                //byte[] key = redisTemplate.getStringSerializer().serialize(token);                if (connection.exists(redisSerializer.serialize(wx_return_url))) {                    byte[] valueByte = connection.hGet(redisSerializer.serialize(wx_return_url), redisSerializer.serialize(token));                    String value = redisTemplate.getStringSerializer().deserialize(valueByte);                    return value;                }                return null;            }        });    }        /**     *      * @param token     * @return     */       public boolean remove(final String token) {           return redisTemplate.execute(new RedisCallback<Boolean>() {             @Override             public Boolean doInRedis(RedisConnection connection) throws DataAccessException {                    RedisSerializer<String> redisSerializer = redisTemplate.getStringSerializer();                    if (connection.exists(redisSerializer.serialize(wx_return_url))) {                          return connection.hDel(redisSerializer.serialize(wx_return_url), redisSerializer.serialize(token))>0?true:false;                      }                     return false;                   }                });           }}

5.Controller中使用

@Autowiredprivate RedisServiceImpl redisService;redisService.set(token, url);// 保存cacheredisService.get(pd.getString("token"));redisService.remove(pd.getString("token"));
