Here i have three Address like. Address1, Address2 and Address3

now I get the User info at @ModelAttribut("user") User user but i didnt get the addresses list from user.getAddress();.
It returns the “[]” empty value for addresslist.
How could i get this list of address objects from jsp to controller.

Can anyone help me please..

Answer 1

It described in documentation, just read section about nesting properties.

For provided case you need to set field names properly:

• user.address[0].city
• user.address[1].city
• user.address[2].city

This code will set cities for 3 address of user. Do similar transformation with other fields.
