Spring整合Jedis抛空异常

这是抛出的异常

下面贴出我的代码：

}
TestServlet测试方法
RedisClientTemplateImpl redisClient = new RedisClientTemplateImpl();
String value = redisClient.set("yaya", "123156644");
System.out.println("获取到的值："+value);
response.sendRedirect("index.jsp");

都有注入为什么抛出空异常，试了很多方法都不行，求大神帮忙解答一下，多分

 <bean id="redisDataSource" class="base.redis.RedisDataSourceImpl">
    <property name="shardedJedisPool"></property>
</bean>
<bean id="redisClientTemplate" class="base.redis.RedisClientTemplateImpl">
    <property name="redisDataSource"></property>
</bean>

你配置都存在这些问题，你可以调试下嘛，问题定位了很快可以解决

ShardedJedis shardedJedis = redisDataSource.getRedisClient();

从代码上来看抛空指针异常的只可能是这，同时看你配置文件

这redisDataSource并没有初始化，所以空指针很正常

 <bean id="redisClientTemplate" class="base.redis.RedisClientTemplateImpl">
    <property name="redisDataSource" ref="redisDataSource"/>
</bean>

有人帮忙解答一下吗？谢谢啦

这是我的redis.properties

redis.pool.maxActive=200
redis.pool.maxIdle=50
redis.pool.minIdle=10
redis.pool.maxWaitMillis=20000
redis.pool.maxWait=300
redis.uri = redis://:password@127.0.0.1:6379/0
redis.timeout=30000
