在 Spring mvc 控制器中访问 Javascript 数组

Question

Right now I am sending some parameters through URL to the controller in spring mvc project. If the parameters are too long the url is more than 2083 characters which IE do not accept more than 2083 characters in a url.So I am thinking to access the front end JavaScript array in the backend controller. How is it possible or any other better alternative suggestion please?

Answer 1

It is not possible "to access the front end JavaScript array in the backend controller". The JavaScript array (and the logic around it) is in the browser, and your Java backend is on your server. The communication path are the URLs.

You're probably currently sending your parameters with GET requests. You have to switch to POST requests, then you'll be able to send much much more than 2000 characters.

See Spring docs section " Mapping Requests With @RequestMapping ", depending on the Spring version you use, eg:

• Spring 3.1.x
• Spring 4.3.x

Answer 2

Use POST instead of GET while making the call to the server side. And have your data in the payload of the request.
