spring与redis整合的一个小demo

准备工作：在本机安装好redis，并且能够成功使用

demo地址：https://github.com/boailiu/springRedisDemo.git

1.首先创建maven项目，pom.xml文件如下

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

        </dependency>

    </dependencies>

</project>

2.创建redis.properties文件

#ip地址
redis.hostName=127.0.0.1
#端口号
redis.port=6379
#如果有密码
redis.password=
#客户端超时时间单位是毫秒 默认是2000
redis.timeout=10000


#最大空闲数
redis.maxIdle=200
#连接池的最大数据库连接数。设为0表示无限制,如果是jedis 2.4以后用redis.maxTotal
#redis.maxActive=600
#控制一个pool可分配多少个jedis实例,用来替换上面的redis.maxActive,如果是jedis 2.4以后用该属性
redis.maxTotal=300
#最大建立连接等待时间。如果超过此时间将接到异常。设为-1表示无限制。
redis.maxWaitMillis=1000
#连接的最小空闲时间 默认1800000毫秒(30分钟)
redis.minEvictableIdleTimeMillis=300000
#每次释放连接的最大数目,默认3
redis.numTestsPerEvictionRun=1024
#逐出扫描的时间间隔(毫秒) 如果为负数,则不运行逐出线程, 默认-1
redis.timeBetweenEvictionRunsMillis=30000
#是否在从池中取出连接前进行检验,如果检验失败,则从池中去除连接并尝试取出另一个
redis.testOnBorrow=true
#在空闲时检查有效性, 默认false
redis.testWhileIdle=true


#redis.sentinel.host1=172.20.1.230
#redis.sentinel.port1=26379


#redis.sentinel.host2=172.20.1.231
#redis.sentinel.port2=26379


#redis.sentinel.host3=172.20.1.232
#redis.sentinel.port3=26379

3.创建spring的配置文件，application.xml配置文件如下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns="http://www.springframework.org/schema/beans"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:cache="http://www.springframework.org/schema/cache"
       xmlns:p="http://www.springframework.org/schema/p"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
     http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
     http://www.springframework.org/schema/aop
     http://www.springframework.org/schema/aop/spring-aop-4.0.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
     http://www.springframework.org/schema/cache
     http://www.springframework.org/schema/cache/spring-cache-4.0.xsd">

    <context:property-placeholder location="classpath:redis.properties"/>

    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxIdle" value="${redis.maxIdle}"></property>
        <property name="maxTotal" value="${redis.maxTotal}"></property>
        <property name="maxWaitMillis" value="${redis.maxWaitMillis}"></property>
<!--        <property name="minEvictableIdleTimeMillis" value="${redis.minEvictableIdleTimeMillis}"></property>
        <property name="numTestsPerEvictionRun" value="${redis.numTestsPerEvictionRun}"></property>
        <property name="timeBetweenEvictionRunsMillis" value="${redis.timeBetweenEvictionRunsMillis}"></property>-->
        <property name="testOnBorrow" value="${redis.testOnBorrow}"></property>
        <property name="testWhileIdle" value="${redis.testWhileIdle}"></property>
    </bean>

    <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" destroy-method="destroy">
        <property name="poolConfig" ref="jedisPoolConfig"></property>
        <property name="hostName" value="${redis.hostName}"></property>
        <property name="port" value="${redis.port}"></property>
        <property name="password" value="${redis.password}"></property>
        <property name="timeout" value="${redis.timeout}"></property>
    </bean>

    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="jedisConnectionFactory"></property>
        <property name="keySerializer">
            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"></bean>
        </property>

        <property name="valueSerializer">
            <bean class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer"></bean>
        </property>

        <property name="hashKeySerializer">
            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"></bean>
        </property>

        <property name="hashValueSerializer">
            <bean class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer"></bean>
        </property>

        <property name="enableTransactionSupport" value="true"></property>
    </bean>

    <bean id="redisUtil" class="springRedis.RedisUtil">
        <property name="redisTemplate" ref="redisTemplate"></property>
    </bean>

</beans>

4.创建类RedisUtil,直接贴代码

package springRedis;

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

/**
 * @author andyliu
 * @date 2018/9/13
 */
public class RedisUtil {

    private RedisTemplate<String,Object> redisTemplate;

    public void setRedisTemplate(RedisTemplate<String,Object> redisTemplate){
        this.redisTemplate = redisTemplate;
    }

    public Object get(String key){
        return key==null ? null : redisTemplate.opsForValue().get(key);
    }

    public boolean set(String key,Object value){
        try{
            redisTemplate.opsForValue().set(key,value);
            return true;
        }catch (Exception e){
            e.printStackTrace();
            return false;
        }
    }

    public boolean hasKey(String key){
        try{
            return redisTemplate.hasKey(key);
        }catch (Exception e){
            e.printStackTrace();
            return false;
        }
    }
}

5.编写测试类

import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import springRedis.RedisUtil;

/**
 * @author andyliu
 * @date 2018/9/13
 */
public class springTest {

    @Test
    public void soutTest(){
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:application.xml");
        RedisUtil redisUtil = (RedisUtil) context.getBean("redisUtil");
        System.out.println(redisUtil.get("testNew"));
    }

    @Test
    public void setTest(){
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:application.xml");
        RedisUtil redisUtil = (RedisUtil) context.getBean("redisUtil");
        boolean result = redisUtil.set("testNew","This is newSetTest");
        System.out.println("这是结果：" + result);
    }

    @Test
    public void hasKeyTest(){
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("application.xml");
        RedisUtil redisUtil = (RedisUtil) context.getBean("redisUtil");
        System.out.println("这是结果:" + redisUtil.hasKey("name"));
    }
}

当然，我在redisUtil中只简单的写了三个方法，然后再测试类中进行set和get测试，更多的功能需要自己去添加。
