springmvc Redis配置使用(Jedis)__redis

首先要在本地安裝redis，具體察看（mac安裝）：http://blog.csdn.net/kirito_j/article/details/79079411

項目環境：maven，springmvc

pom.xml

<dependency>      <groupId>org.springframework.data</groupId>      <artifactId>spring-data-redis</artifactId>      <version>1.0.2.RELEASE</version>    </dependency>    <dependency>      <groupId>redis.clients</groupId>      <artifactId>jedis</artifactId>      <version>2.1.0</version>    </dependency>

web.xml

<servlet>    <servlet-name>springmvc</servlet-name>    <!--使用了springframe的servlet-->    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <init-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:/META-INF/springmvc-servlet.xml</param-value>    </init-param>    <load-on-startup>1</load-on-startup>  </servlet>  <servlet-mapping>    <servlet-name>springmvc</servlet-name>    <url-pattern>/</url-pattern>  </servlet-mapping>

applicaton.properties

# Redis settingsredis.host=127.0.0.1redis.port=6379redis.pass=redis.maxIdle=300redis.maxActive=600redis.maxWait=1000redis.testOnBorrow=true

springmvc-servlet.xml

<!-- redis快取資料庫的相關配置 -->    <context:property-placeholder            ignore-resource-not-found="true" location="classpath*:application.properties" />    <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">        <property name="maxIdle" value="${redis.maxIdle}" />        <property name="maxActive" value="${redis.maxActive}" />        <property name="maxWait" value="${redis.maxWait}" />        <property name="testOnBorrow" value="${redis.testOnBorrow}" />    </bean>    <bean id="connectionFactory"          class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"          p:host-name="${redis.host}" p:port="${redis.port}" p:password="${redis.pass}"          p:pool-config-ref="poolConfig" />    <bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">        <property name="connectionFactory" ref="connectionFactory" />    </bean>

使用方法，利用@Autowired注入RedisTemplate<k,v>
