It is believed that many inexperienced people do not know what to do about how to encapsulate Fields objects in Storm. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Record a small Tips

1 Storm in Emit

Public class Values extens ArrayList {public Values () {} public Values (Object... vals) {super (vals.length); for (Object o:val) {add (o);}}

1 Values inherits from ArrayList and initializes the length of List through super (vals.lengh)

2 initialize vals through the for loop add

3 when emit transmits data, it is encapsulated into a Fields object by values object.

Through the encapsulation of the Fields object, the JAVABEAN is passed directly in the process of transmission.
