   I check the code, and found a bug:
   ![image](https://user-images.githubusercontent.com/44333070/95844736-d627c080-0d7b-11eb-93b0-aae57716d59c.png)
   this is "ProcessInstanceId"，but in database，table "t_ds_command" has a wrong data:

   so tmpObj is "processInstanceId":

   so I got a NullPointerException，Idelete the wrong data, and now it is success!
   
   t_ds_command中的脏数据包含的processInstanceId为小写开头，但是代码里面 却是大写开头的，这是导致空指针的原因，至于脏数据产生的原因，猜测可能是写入mysql时产生了锁，该条数据无法被删除，这也导致了整个ds不会再生成新的调度任务，我是通过重启解决了锁的问题，但是这个脏数据也就永远不会被删除了，而这个脏数据的大小写的问题，可能需要大佬来解释一下了
