maven配置springmvc+spring data red

一、概述

redis，键值存储系统，面试中常问到的是redis数据结构，在公司中还能使用redis的主键生成uuid，其他的我也不知道了，因为还轮不到我做系统。

二、配置使用

1.添加依赖

        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-redis</artifactId>
            <version>1.5.2.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.9.0</version>
        </dependency>

2.配置applicationContext-Redis.xml，并把文件添加到web.xml启动项中

<?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:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:amq="http://activemq.apache.org/schema/core"
       xmlns:jms="http://www.springframework.org/schema/jms"
       xmlns:mvc="http://www.alibaba.com/schema/stat"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.1.xsd
        http://activemq.apache.org/schema/core
        http://activemq.apache.org/schema/core/activemq-core-5.7.0.xsd
        http://www.alibaba.com/schema/stat http://www.alibaba.com/schema/stat.xsd
        http://www.springframework.org/schema/jms
        http://www.springframework.org/schema/jms/spring-jms-4.1.xsd ">


    <context:annotation-config />

    <!-- scanner redis properties  -->
    <context:property-placeholder location="classpath:redis.properties" ignore-unresolvable="true"/>

    <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxIdle" value="${redis.maxIdle}" />
        <property name="minIdle" value="${redis.minIdle}" />
        <property name="maxTotal" value="${redis.maxTotal}" />
        <property name="testOnBorrow" value="${redis.testOnBorrow}" />
    </bean>

    <bean id="redisConnectionFactory" 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="redisConnectionFactory" />
    </bean>

</beans>

redis.properties

# Redis settings
redis.host=localhost
redis.port=6379
redis.pass=

redis.maxIdle=600
redis.minIdle=300
redis.maxTotal=1000
redis.testOnBorrow=true

3.直接使用spring data redis 中封装的方法进行操作

package com.web.test.controller;

import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.annotation.Resource;


@RestController
public class TestController {

    @Resource(name="redisTemplate")
    private RedisTemplate<String,String> redisTemplate;

    @RequestMapping("/redisTest")
    public String redisTest(){
        return redisTemplate.opsForValue().get("username");
    }

}

-end-
