抽象类注入JedisPool失败

public abstract class BusinessIdGenerateAbstract implements Serializable{

protected JedisPool jedisPool;

protected void fromRedis(String idName,Queue queue){

    try {
        jedis = jedisPool.getResource();
        Map<String,String> model = jedis.hgetAll(idName);
        Long redisCurrentId = Long.valueOf(model.get("currentId"));
        for (int i = 1; i <= increase; i++) {
            redisCurrentId += 1;
            queue.offer(redisCurrentId);
        }
        model.put("currentId", String.valueOf(redisCurrentId));
        jedis.hmset(idName,model);
    } catch (Exception e) {
        e.printStackTrace();
        logger.error("fromRedis--failed");
    }finally{
        if(null != jedis) {
            jedisPool.returnResource(jedis);
        }
    }
}
//spring配置
 <bean id="businessIdGenerateAbstract" class="com.fangcang.sequence.entity.BusinessIdGenerateAbstract" abstract="true">
    <property name="jedisPool" ref="jedisPool"></property>
</bean>

<bean id="jedisPool" class="redis.clients.jedis.JedisPool">
    <constructor-arg index="0" ref="jedisPoolConfig" />
    <constructor-arg index="1" value="${redis.ip}" />
    <constructor-arg index="2" value="${redis.port}" type="int"/>
    <constructor-arg index="3" value="${common.redis.timeout}" type="int"/>
    <constructor-arg index="4" value="${common.redis.password}" />
</bean>

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
    <property name="maxIdle" value="${common.redis.maxIdle}"></property>
    <property name="minIdle" value="${common.redis.minIdle}"></property>
    <property name="maxTotal" value="${common.redis.maxTotal}"></property>
    <property name="maxWaitMillis" value="${common.redis.maxWait}"></property>
</bean>

启动Jboss后，调用方法时，报错，jedisPool is null
