springmvc整合redis

新换环境,又有新东西可以学习了,哈皮! 抽空学习之余看了一下redis,个人对Springmvc的爱是忠贞不渝,所以整理了一下Springmvc整合redis的环境搭建.分享学习.

第一步: 创建maven项目:

实例pom.xml内容如下

第二步:配置文件整合

Web.xml文件配置

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.4"         xmlns="http://java.sun.com/xml/ns/j2ee"         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>        <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>/WEB-INF/context/spring-context.xml</param-value>    </context-param>        <!-- Spring字符集过滤器 -->    <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/spring-mvc.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>

spring-context.xml内容

<?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:p="http://www.springframework.org/schema/p"    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"    xmlns:util="http://www.springframework.org/schema/util"    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd              http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd              http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd                          http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd">            <!-- 激活@Controller模式 -->    <mvc:annotation-driven />        <!-- 对包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 需要更改 -->    <context:component-scan base-package="com.pudp.bae.*" />        <!-- 引入同文件夹下的redis属性配置文件 -->    <import resource="redis-context.xml"/></beans>

redis-context.xml内容

<beans     xmlns="http://www.springframework.org/schema/beans"            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"           xmlns:p="http://www.springframework.org/schema/p"            xmlns:tx="http://www.springframework.org/schema/tx"           xmlns:context="http://www.springframework.org/schema/context"           xsi:schemaLocation="            http://www.springframework.org/schema/beans             http://www.springframework.org/schema/beans/spring-beans-3.0.xsd            http://www.springframework.org/schema/tx             http://www.springframework.org/schema/tx/spring-tx-3.0.xsd            http://www.springframework.org/schema/context            http://www.springframework.org/schema/context/spring-context-3.0.xsd               ">        <!-- scanner redis properties  -->     <context:property-placeholder location="/WEB-INF/property/redis.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>           </beans>               

Redis.properties文件内容

# Redis settings#redis.host=192.168.20.101#redis.port=6380#redis.pass=foobaredredis.host=127.0.0.1redis.port=6379redis.pass=  redis.maxIdle=300redis.maxActive=600redis.maxWait=1000redis.testOnBorrow=true

第三步:Springmvc对Redis的支持与实例应用.

实例对象

package com.pudp.bae.model;import com.pudp.bae.base.BaseModel;public class Member extends BaseModel{    /**     *      */    private static final long serialVersionUID = -1959528436584592183L;            private String id;    private String nickname;        public Member(){}        public Member(String id, String nickname){        this.setId(id);        this.setNickname(nickname);    }        public String getId() {        return id;    }    public void setId(String id) {        this.id = id;    }    public String getNickname() {        return nickname;    }    public void setNickname(String nickname) {        this.nickname = nickname;    }    }

Redis对象持久化操作

package com.pudp.bae.base;import java.io.Serializable;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.data.redis.core.RedisTemplate;import org.springframework.data.redis.serializer.RedisSerializer;public abstract class RedisGeneratorDao<K extends Serializable, V extends Serializable>  {        @Autowired    protected RedisTemplate<K,V> redisTemplate ;    /**      * 设置redisTemplate      * @param redisTemplate the redisTemplate to set      */      public void setRedisTemplate(RedisTemplate<K, V> redisTemplate) {          this.redisTemplate = redisTemplate;      }            /**      * 获取 RedisSerializer      * <br>------------------------------<br>      */      protected RedisSerializer<String> getRedisSerializer() {          return redisTemplate.getStringSerializer();      }      }

package com.pudp.bae.base;import java.io.Serializable;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.data.redis.core.RedisTemplate;import org.springframework.data.redis.serializer.RedisSerializer;public abstract class RedisGeneratorDao<K extends Serializable, V extends Serializable>  {        @Autowired    protected RedisTemplate<K,V> redisTemplate ;    /**      * 设置redisTemplate      * @param redisTemplate the redisTemplate to set      */      public void setRedisTemplate(RedisTemplate<K, V> redisTemplate) {          this.redisTemplate = redisTemplate;      }            /**      * 获取 RedisSerializer      * <br>------------------------------<br>      */      protected RedisSerializer<String> getRedisSerializer() {          return redisTemplate.getStringSerializer();      }      }
