简介:
实现reids master slave 模式添加哨兵(sentinel)监控,当主机down掉后备机承担主机身份进行生产工作。
实施:
1.先依照spring redis 整合http://see-you-again.iteye.com/admin/blogs/2323435完成非哨兵监控模式下的配置。
2.修改pom文件如下:
<?xml version="1.0" encoding="UTF-8"?>
<!--suppress ALL -->
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<context:property-placeholder location="classpath:redis.properties" />
<bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig"
p:maxIdle="${redis.maxIdle}"
p:maxTotal="${redis.maxActive}"
p:maxWaitMillis="${redis.maxWait}"
p:testOnBorrow="${redis.testOnBorrow}">
</bean>
<!-- 不使用哨兵
<bean id="jedisConnFactory"
class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
p:usePool="true"
p:hostName="127.0.0.1"
p:port="7000"
p:timeout="200"
p:password=""
p:poolConfig-ref="poolConfig"/>
-->
<bean id="jedisConnFactory"
class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
<constructor-arg name="sentinelConfig" ref="redisSentinelConfiguration"></constructor-arg>
<constructor-arg name="poolConfig" ref="poolConfig"></constructor-arg>
</bean>
<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>
<!-- 注意这里配置的是哨兵信息,而非redis服务信息-->
<bean class="org.springframework.data.redis.connection.RedisNode">
<constructor-arg index="0" value="127.0.0.1" />
<constructor-arg index="1" value="5001" />
</bean>
<bean class="org.springframework.data.redis.connection.RedisNode">
<constructor-arg index="0" value="127.0.0.1" />
<constructor-arg index="1" value="5002" />
</bean>
<bean class="org.springframework.data.redis.connection.RedisNode">
<constructor-arg index="0" value="127.0.0.1" />
<constructor-arg index="1" value="5003" />
</bean>
</set>
</property>
</bean>
<bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate" >
<property name="connectionFactory" ref="jedisConnFactory" />
<property name="enableTransactionSupport" value="true" />
</bean>
<bean id="userDao" class="com.test.redis.UserDao" >
<constructor-arg name="redisTemplate" ref="redisTemplate"/>
</bean>
<bean id="redisDao" class="com.test.redis.RedisDao" >
<constructor-arg name="redisTemplate" ref="redisTemplate"/>
</bean>
</beans>
