SpringMVC整合Redis实例

1.新建maven工程

2.导入jar包

<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 http://maven.apache.org/maven-v4_0_0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>com.nineclient</groupId>  <artifactId>redis_spring</artifactId>  <packaging>war</packaging>  <version>0.0.1-SNAPSHOT</version>  <name>redis_spring Maven Webapp</name>  <url>http://maven.apache.org</url>  <properties>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <spring.version>3.0.5.RELEASE</spring.version>  </properties>  <dependencies>    <dependency>  <groupId>javax.servlet</groupId>    <artifactId>servlet-api</artifactId><version>2.5</version><scope>provided</scope></dependency><!-- config redis data and client jar-->     <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>        <!-- spring begin -->  <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-webmvc</artifactId>      <version>${spring.version}</version>  </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-jdbc</artifactId>      <version>${spring.version}</version>  </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-context</artifactId>      <version>${spring.version}</version>  </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-aop</artifactId>      <version>${spring.version}</version>  </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-core</artifactId>      <version>${spring.version}</version></dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-test</artifactId>      <version>${spring.version}</version>  </dependency><!-- spring end --><dependency>    <groupId>log4j</groupId>    <artifactId>log4j</artifactId>    <version>1.2.17</version></dependency>  </dependencies>  <build>    <finalName>redis_spring</finalName>  </build></project>

3.编写web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.4" aaxmlns="http://java.sun.com/xml/ns/j2ee"    aaxmlns:xsi="w3.org/2001/XMLSchema-instance"    aaxsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">    <display-name>SpringMVCRedis</display-name>    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener        </listener-class>    </listener>     <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>/WEB-INF/context/applicationContext.xml</param-value>    </context-param>     <filter>        <filter-name>SpringEncodingFilter</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>SpringEncodingFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>     <servlet>        <servlet-name>mvc</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet        </servlet-class>        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>/WEB-INF/context/dispatcher-servlet.xml</param-value>        </init-param>        <load-on-startup>2</load-on-startup>    </servlet>     <servlet-mapping>        <servlet-name>mvc</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping>     <welcome-file-list>        <welcome-file>index.jsp</welcome-file>    </welcome-file-list></web-app>

代码结束

开始测试

先add一个，然后在query

<a href="<%=basePath%>member/add">增加成员</a><a href="<%=basePath%>member/1/query">查询成员</a>

先增加一个用户

在查询这个数据

注意点

运行程序时需要启动redis.cmd

还需要注意springmvc引入的版本和jedis的版本兼容性，我在这里当时卡了好久，最后发现是版本不兼容，不兼容导致redisTemplate取不到
