Spring + SpringMVC + Mybatis项目中redis的配置及使用

maven文件

<!-- redis -->
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>${jedis.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-redis</artifactId>
            <version>${spring-data-redis.version}</version>
        </dependency>

1.redis配置文件redis.properties

#redis的服务器地址
redis.host=127.0.0.1
#redis的服务端口
redis.port=6379
#密码
redis.password=
#链接数据库
redis.default.db=0
#客户端超时时间单位是毫秒
redis.timeout=100000
#最大连接数
redis.maxActive=300
#最大空闲数
redis.maxIdle=100
#最大建立连接等待时间
redis.maxWaitMillis=1000

 

2.spring-redis.xml读取参数

<?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"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.0.xsd">
    <context:property-placeholder location="classpath:redis.properties"/>
    <!-- Redis 配置 -->
    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxTotal" value="${redis.maxActive}"/>
        <property name="maxIdle" value="${redis.maxIdle}"/>
        <property name="maxWaitMillis" value="${redis.maxWaitMillis}"/>
        <property name="testOnBorrow" value="true"/>
    </bean>

    <!-- redis单节点数据库连接配置 -->
    <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
        <property name="hostName" value="${redis.host}"/>
        <property name="port" value="${redis.port}"/>
        <property name="password" value="${redis.password}"/>
        <property name="poolConfig" ref="jedisPoolConfig"/>
    </bean>

    <!-- redisTemplate配置 -->
    <bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
        <property name="connectionFactory" ref="jedisConnectionFactory"/>
    </bean>
</beans>

3.web.xml中读取spring配置文件

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath*:spring-*.xml
        </param-value>
    </context-param>
    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>classpath:log4j.properties</param-value>
    </context-param>

这样redis在项目中就算配好了

4.redis工具类

package com.mz.usps.common.component;

import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;
import java.util.concurrent.TimeUnit;

/**
 * Redis模板
 *
 * @author sjl
 * @date 2018-03-12 15:18
 **/
@Component
public class RedisCache {
    @Resource
    private RedisTemplate redisTemplate;

    public void setValue(Object key, Object value) {
        redisTemplate.opsForValue().set(key, value);
    }
    public void setValue(Object key, Object value, long timeout, TimeUnit unit) {
        redisTemplate.opsForValue().set(key, value, timeout, unit);
    }

    public Object getValue(Object key) {
        Object value = redisTemplate.opsForValue().get(key);
        return value;
    }
}

5.Redis使用实战

在哪个类中使用

@Autowired
    RedisCache redisCache;
加到哪个类中

6.方法中存值

redisCache.setValue(token, "1", 1, TimeUnit.DAYS);
token为key值   "1"为value  1时间   TimeUnit.DAYS为时间单位
将key value 存入redis中一天
