我想将对象列表从 jsp 发送到控制器。

实际上我有用户实体，它与地址实体有一对多的关系。我的jsp如下：

<div class="label"><b>First Name :</b></div>
                    <div class="leftSide"><input type="text" name="firstName" class="textBox" style="width:250px;" /></div>
                    <div class="clr ht5"></div>

                    <div class="label"><b>Company :</b></div>
                    <div class="leftSide"><input type="text" name="company" class="textBox" style="width:250px;" /></div>
                    <div class="clr ht5"></div>
                 </div>
                 <div class="rightHalfColumn">
                    <div class="label"><b>Last Name :</b></div>
                    <div class="leftSide"><input type="text" name="lastName" class="textBox" style="width:250px;" /></div>
                    <div class="clr ht5"></div>

                    <div class="label"><b>Email Address :</b></div>
                    <div class="leftSide"><input type="text" name="email" class="textBox" style="width:250px;" /></div>
                    <div class="clr ht5"></div>

                    Address 1
                    <div class="label"><b>Address 1 :</b></div>
                    <div class="leftSide"><input type="text" name="address1" class="textBox" style="width:250px;" /></div>

                    <div class="label"><b>City :</b></div>

这里我有三个地址。地址 1、地址 2 和地址 3

现在我得到了用户信息，@ModelAttribut("user") User user但我没有得到地址列表user.getAddress();。它返回地址列表的“[]”空值。我如何从 jsp 到控制器中获取此地址对象列表。

任何人都可以帮助我吗..

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.
