In the job, large amount of redis connections are created on each TM, is there some ideas? code like:

def main(args:Array[String]): Unit = {
 val env = StreamExecutionEnvironment.getExecutionEnvironment
 env.addSource(new Source).setParallelism(4).addSink(new Sinker).setParallelism(4)
 env.execute()
}

class Sinker extends RichSinkFunction[String]{


 lazy val applicationContext = new ClassPathXmlApplicationContext("application-redis-context.xml")
 lazy val redisTemplate =applicationContext.getBean("redisTemplate", classOf[RedisTemplate[String, String]])

 override def invoke(value: String, context: SinkFunction.Context[_]): Unit = {
 val value = redisTemplate.opsForValue().get("key01")
 println(value)
 }
}
