ssm+redis整合之redis连接池注入

Posted 2020-09-28 L_O_V_E_Java

package com.tp.soft.redis;

import javax.annotation.Resource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;

public class RedisCacheTransfer {
    
    @Autowired
    public void setJedisConnectionFactory(JedisConnectionFactory jedisConnectionFactory) {
        RedisCacheAn.setJedisConnectionFactory(jedisConnectionFactory);
    }

}

 

spring-redis注入

<bean id="jedisConnectionFactory" class="com.tp.soft.redis.RedisCacheTransfer">
        <property name="jedisConnectionFactory" ref="connectionFactory"></property>
    </bean>

 

二级缓存引入类
