what are best coding practise to transfer the data from form to the servlet or spring mvc controller

all the html forms submit the input parameters in string. do we have any standards to transfer the data to the servlet.

ex. I want to sent a String[][] 2d array which contains {{"name:test","value="test" }{"name=test1","value=value2", "description=sample description"}}}

Now I am sending the value in |test,test|test1,value2,sample description| and in the spring controller parsing the data using "|" as delimiter.

Do we any other of sending the request from the html form to the servlet?
