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：
第一步：在pox.xml中引入jar
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

需要生成的目标class文件的编译版本 --> <encoding>utf-8</encoding> </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
以上就是springmvc整合redis的过程，如果有什么问题都可以联系我。
