最近在学习redis，虽然现在还不是很熟练。不过可以进行简单的框架整合开发。那么我就把我的springmvc整合redis的过程分享给大家。

IDE:我使用的是IDEA。

首先看一下我的工程结构：

springmvc整合redis（一）

第一步：在pox.xml中引入jar

        </configuration>
      </plugin>

    </plugins>
  </build>
</project>

第二步：配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         id="WebApp_ID" version="3.0">

  <!-- 配置spring -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!-- 编码过滤器 -->
  <filter>
    <filter-name>charsetEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
      <param-name>forceEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>

  <filter-mapping>
    <filter-name>charsetEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <!-- 配置springmvc -->
  <servlet>
    <servlet-name>springDispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springDispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern><!-- 拦截所有请求 -->
  </servlet-mapping>

</web-app>

第三步：配置springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

    <!-- 配置自动扫描的包  -->
    <context:component-scan base-package="com.jiangfx.controller"/>

    <!-- 配置静态资源文件 -->
    <mvc:default-servlet-handler/>

    <!-- 开启注解模式 -->
    <mvc:annotation-driven/>
    <!-- 配置视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp"></property><!-- 视图路径 -->
        <property name="suffix" value=".jsp"></property><!-- 视图后缀名 -->
    </bean>
</beans>

第四步：配置applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">

    <!-- 配置扫描的包 -->
    <context:component-scan base-package="com.jiangfx.service"/>

    <!-- 引入spring-data-redis.xml -->
    <import resource="spring-data-redis.xml"/>

</beans>

第五步：配置spring-data-redis.xml

redis.properties

# Redis Setting
# Redis默认有16个库，序号是0-15，默认是选中的是0号数据库
spring.redis.database=0  
# Redis服务器地址
spring.redis.host=（你的地址） 
# Redis服务器连接端口，默认是6379
spring.redis.port=6379  
# Redis服务器连接密码（默认为空）
spring.redis.password=
# 连接池最大阻塞等待时间（使用负值表示没有限制），根据实际情况修改
spring.redis.pool.maxWaitMillis=-1  
# 连接池中的最大空闲连接，根据实际情况修改
spring.redis.pool.maxIdle=8  
# 连接池中的最小空闲连接，根据实际情况修改
spring.redis.pool.minIdle=0  
# 连接超时时间（毫秒），根据实际情况修改
spring.redis.timeout=2000

spring-data-redis.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cache="http://www.springframework.org/schema/cache"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:redis="http://www.springframework.org/schema/redis" xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-4.0.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/redis http://www.springframework.org/schema/redis/spring-redis-1.0.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">

    <!-- 载入redis.properties,这里要特别注意，如果有多个properties文件，必须用逗号分开，不能写成两个 <context:property-placeholder/> -->
    <context:property-placeholder location="classpath:redis.properties" />

    <!-- 配置JedisPoolConfig相关参数 -->
    <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxIdle" value="${spring.redis.pool.maxIdle}"></property>
        <property name="minIdle" value="${spring.redis.pool.minIdle}"></property>
        <property name="maxWaitMillis" value="${spring.redis.pool.maxWaitMillis}"></property>
    </bean>

    <!-- 配置redis服务器信息 -->
    <bean id="connectionFactory"
          class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
        <property name="poolConfig" ref="poolConfig"></property>
        <property name="hostName" value="${spring.redis.host}"></property>
        <property name="port" value="${spring.redis.port}"></property>
        <!--<property name="password" value="${spring.redis.password}"></property>-->
        <property name="database" value="${spring.redis.database}"></property>
        <property name="timeout" value="${spring.redis.timeout}"></property>
    </bean>

    <!-- 配置RedisTemplate -->
    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="connectionFactory"></property>
        <property name="keySerializer">
            <bean
                    class="org.springframework.data.redis.serializer.StringRedisSerializer"></bean>
        </property>
        <property name="valueSerializer">
            <bean
                    class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"></bean>
        </property>

        <property name="hashKeySerializer">
            <bean
                    class="org.springframework.data.redis.serializer.StringRedisSerializer"></bean>
        </property>
        <!-- 使用JacksonJsonRedisSerializer需要引入jar包：barchart-wrap-jackson-1.8.6-build001.jar -->
        <!-- JacksonJsonRedisSerializer 需要一个有参的构造函数，因此需要配置constructor-arg -->
        <property name="hashValueSerializer">
            <bean
                    class="org.springframework.data.redis.serializer.JacksonJsonRedisSerializer">
                <constructor-arg type="java.lang.Class" value="java.lang.Object"></constructor-arg>
            </bean>
        </property>
    </bean>

    <!-- 配置redis连接池 -->
    <bean class="redis.clients.jedis.JedisPool">
        <constructor-arg ref="poolConfig" />
        <constructor-arg value="${spring.redis.host}" />
        <constructor-arg type="int" value="${spring.redis.port}" />
        <constructor-arg type="int" value="${spring.redis.timeout}" />
        <constructor-arg type="java.lang.String" value="${spring.redis.password}" />
        <constructor-arg type="int" value="${spring.redis.database}" />
    </bean>
</beans>

第六步：测试

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.data.redis.core.RedisTemplate;

/**
 * Created by jiangfeixiang on 2018/4/26
 */
public class SpringmvcRedisTest {
    private static ApplicationContext applicationContext;

    static{
        applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
    }

    @Test
    public void testApplicationContext(){
        System.out.println("11111111111111111"+applicationContext);
    }
    @Test
    public void testRedisConnection(){
        RedisTemplate redisTemplate = (RedisTemplate)applicationContext.getBean("redisTemplate");
        redisTemplate.renameIfAbsent("k2", "k1");//如果key=k2存在，则将key修改为k1
        System.out.println(redisTemplate);
    }
}

如何查看是否成功?我这里是通过可视化软件：Redis Desktop Manager，你也可以直接在redis-cli客户端查看
