front end transcodes the picture base64, places it in an array of base64 strings, and passes it to the background when the page is submitted.

this is the page submitted by the front end, and multiple pictures may be submitted

the situation in which there is a problem

submit a single picture

ajaxsize1

","

ajax

","

is this because when SpringMVC does parameter binding conversion, it will split the parameters of the array type? But why not multiple pictures? Is there a solution?

Thanks in advance!
