@RequestMapping(value = "user", method = RequestMethod.POST) 
public String test(User user) { 
     System.out.println(user.getName()); 
     List<Link> links = user.getLinks();

user.jsp

[form:form modelAttribute="user" method="post" action="/user"] 
[form:input path="name" /] 
[form:input path="addr" /] 
[form:input path="tel" /] 
[form:input path="addr" /] 
[form:input path="tel" /] 
[input type="submit"][/input] 
[/form:form] 

誰能告訴我如何做到這一點！

[form:form modelAttribute="user" method="post" action="/user"] 
[form:input path="name" /] 
[form:input path="links[0].addr" /] 
[form:input path="links[0].tel" /] 
[form:input path="links[1].addr" /] 
[form:input path="links[1].tel" /] 
[input type="submit"][/input] 
[/form:form]
