Java Address bar Pass parameters have a length limit

Today in the project data export, if it is small data volume is not a problem, if you export 500 data at a time error. The error message is that the address cannot be found. Finally followed the code, the original address bar passed the parameter is too large caused. To the background URL address is as follows:

I copied the above address to the text exactly 2kb. Search the Internet to find the original address bar number of words in the maximum limit of 2kb.

The workaround is to assign the parameters that need to be passed to the background to the hidden form field of the page, and then back to the background action.

The implementation code is as follows:

The JSP code is as follows:

<input type= "hidden" id= "Checkedids" name= "Checkedids"/>

JS Code:

$ ("#checkedIds"). Val (Getcheckedid ()); Getcheckedid () method to get the value of the check box

Action Code:

Request.getparameter ("Checkedids");

==========================

Originally thought with tomcat this parameter about Maxparametercount, later went through the test found that this is only limit the number of input to commit. Instead of the address bar length.

Java Address bar Pass parameters have a length limit
