redis与spring的集成

首先需要安装redis

乌班图的安装 apt-get install redis-server

然后是修改 /etc/redis/redis.conf 文件 修改里面的 bind 127.0.0.1 改成你的外网ip这样 外网才能访问

然后/etc/init.d/redis-server restart

客户端与spring集成 需要一下jar包

下载后配置applicationContext.xml spring的配置文件

加入(注意 sentinels的地址是你客户端的地址 不要与jedisConnFactory中的服务器端地址搞混)

<bean id="redisSentinelConfiguration"
class="org.springframework.data.redis.connection.RedisSentinelConfiguration">
<property name="master">
<bean class="org.springframework.data.redis.connection.RedisNode">
<property name="name" value="mymaster"></property>
</bean>
</property>
<property name="sentinels">
<set>
<bean class="org.springframework.data.redis.connection.RedisNode">
<constructor-arg index="0" value="192.168.1.18" />
<constructor-arg index="1" value="7031" />
</bean>
<!--    <bean class="org.springframework.data.redis.connection.RedisNode">
<constructor-arg index="0" value="10.6.1**.**6" />
<constructor-arg index="1" value="7031" />
</bean>
<bean class="org.springframework.data.redis.connection.RedisNode">
<constructor-arg index="0" value="10.6.1**.**1" />
<constructor-arg index="1" value="7031" />
</bean> -->
</set>
</property>
</bean>

<bean id="jedisConnFactory"
class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
<property name="hostName" value="115.XX.XXX.XX"/>
<property name="port" value="6379"/>
<property name="usePool" value="false"/>
<constructor-arg ref="redisSentinelConfiguration"/>
</bean>

<bean id="RedisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
<property name="connectionFactory" ref="jedisConnFactory" />
</bean>

然后再程序中可以这样调用

@Autowired
private RedisTemplate<String, Object> redisTemplate;

@RequestMapping("/selecttest")
@ResponseBody
public String selecttest(HttpServletRequest request) {
redisTemplate.opsForValue().set("name", "周小帅");
System.out.println(redisTemplate.opsForValue().get("name"));
return redisTemplate.opsForValue().get("name");

}

感觉和memached的集成差不多 但是 听说redis的功能要强大的许多，，，继续研究中

后续补充：

另一种简单的xml实现方式

<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" p:use-pool="true"
p:host-name="IP" p:port="6379" p:password="XXXX" />
<!-- redis template definition -->
<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate" p:connection-factory-ref="jedisConnectionFactory"/>

实现代码map取值

name="";
}
Object redisname=redisTemplate.opsForHash().entries(name);//取map值
if (redisname!=null) {

return new ModelAndView("/news", modelMap);
}
modelMap.put("pageNo", Integer.parseInt(pageNo));

}

}

modelMap.put("list", list);
redisTemplate.opsForValue().set(name, modelMap.toString(), 10);
return new ModelAndView("/news", modelMap);

}
}
