Feat/yunti build annotation

[WeiMengXS]

I left a mark where yunti needs to add logic:

  //internal version: replace strCharge begin, please do not modify this annotation and refrain from inserting any code between the beginning and end lines of the annotation.

  //internal version: replace strCharge end, please do not modify this annotation and refrain from inserting any code between the beginning and end lines of the annotation.
