问题内容

我已经通过像许多环节去Jedis,无法获取jedis连接:无法从池中获取资源,并不能得到Jedis连接;
无法从池中获取资源,但仍收到以下错误。

在Spring Batch中 使用 Spring Data Redis, 并从mysql读取数据并写入 Redis
DB。似乎有些连接错误。

下面的错误供参考。

我正在使用以下简单配置。

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"
       p:max-total="5" 
       p:test-on-borrow="true" 
       p:test-on-return="true"/>


    <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" 
        p:hostName="10.10.10.10" 
        p:port="6379" 
        p:use-pool="true">
        <constructor-arg ref="jedisPoolConfig" />
    </bean>


    <!-- This for KEY -->   
    <bean id="keySerializer" class="org.springframework.data.redis.serializer.StringRedisSerializer" />
    <bean id="hashKeySerializer" class="org.springframework.data.redis.serializer.StringRedisSerializer" />

    <!-- This is for VALUE -->
    <bean id="hashValueSerializer" class="org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer" >
        <constructor-arg name="type" value="java.lang.String" />
    </bean>
    <bean id="valueSerializer" class="org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer" >
        <constructor-arg name="type" value="java.lang.String" />
    </bean>

    <!-- redis template definition -->
    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate" 
        p:enableTransactionSupport="true"
        p:connection-factory-ref="jedisConnectionFactory"
        p:keySerializer-ref="keySerializer"
        p:hashKeySerializer-ref="hashKeySerializer"
        p:valueSerializer-ref="valueSerializer"
        p:hashValueSerializer-ref="hashValueSerializer" />

问题答案:

我在这里发布了答案:无法在10.XX.XX.28:6379处连接到Redis:未知错误-从Spring
Batch或Windows计算机访问时。

解决方案对我来说很好。只是配置没有其他改变。
