Answer 1

Use a POST rather than a GET. The query string is limited in length, and you can't do anything about it. If you have a large amount of data to send, use a POST instead of a GET.

Answer 2

Change your HTML form type to "post"

If U'r using JSON, this may helpful for JSON POST request

Using JSON POST Request

Answer 3

在JSP中，可以使用request.setattribute（）进行设置，并可以使用request.getattribute（）在目标位置获取它。
