ssm+redis整合之redis连接池注入
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
