                  问题描述

                  我正在尝试从表单中填充 bean 列表:

                  I'm trying to populate a List of beans from a form:

                  public class Foo {
                     public String attr1;
                     public String attr2;
                  }
                  
                  public class Bar {
                     public List<Foo> foos;
                  }
                  
                  public class StrutsAction extends Action {
                     public Bar bar;
                  }
                  

                  那么在我的 Struts2 表单中,填充 Foo 的最佳方式是什么?直觉上,我想做:

                  So in my Struts2 form, what's the best way to populate Foo? Intuitively, I want to do:

                  <input type="hidden" name="bar.foos.attr1" />
                  

                  但这不起作用并且会导致冲突.我确定答案很简单,我忽略了它.

                  but that isn't working and would cause collisions. I'm sure the answer is very simple and I'm overlooking it.

                  推荐答案

                  如果我理解正确,您只是希望每个隐藏字段的名称不同?

                  If I understand it correctly, you just want different name for each hidden field?

                  <s:iterator value="bars" status="key">
                      <s:hidden name="bar.foos[%{#key.index}].attr1" value="attr1" />
                      <s:hidden name="bar.foos[%{#key.index}].attr2" value="attr2" />
                  </s:iterator>
                  

                  这应该给你相当于

                  <input type="hidden" name="bar.foos[0].attr1" value="some value" />
                  <input type="hidden" name="bar.foos[0].attr2" value="some other value" />
                  <input type="hidden" name="bar.foos[1].attr1" value="some value" />
                  <input type="hidden" name="bar.foos[1].attr2" value="some other value" />
                  

                  如果你有合适的getter/setter,它应该在提交表单时设置所有的值.

                  If you have proper getter/setter, it should set all the values when the form is being submitted.
