使用Spring 3 MVC将List 作为表单支持对象，正确的语法？

使用Spring 3 MVC将List 作为表单支持对象，正确的语法？

也许这回答了你的问题：

ConTROLLER :

@Controller("/")public class FooController{    //returns the ModelAttribute fooListWrapper with the view fooForm    @RequestMapping(value = "/FOO", method = RequestMethod.GET)    public String getFooForm(Model model) {        FooListWrapper fooListWrapper = new FooListWrapper();        fooListWrapper.add(new Foo());        fooListWrapper.add(new Foo());        //add as many FOO you need        model.addAttribute("fooListWrapper", fooListWrapper);        return "fooForm";    }    @RequestMapping(value = "/FOO", method = RequestMethod.POST)    public String postFooList(@ModelAttribute("fooListWrapper")FooListWrapper fooListWrapper, Model model) {        //...........    }}

FOO LIST WRAPPER：

public class FooListWrapper {    private List<Foo> fooList;    public FooListWrapper() {         this.fooList = new ArrayList<Foo>();    }    public List<Foo> getFooList() {        return fooList;    }    public void setFooList(List<Foo> fooList) {        this.fooList = fooList;    }    public void add(Foo foo) {        this.fooList.add(foo);    }}

FOO类：

public class Foo {    private String name;    public Foo() {    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }}

JSP VIEW（名称= fooForm）：

<c:url var="fooUrl" value="/FOO"/><form:form id="frmFoo" action="${fooUrl}" method="POST" modelAttribute="fooListWrapper">    <c:forEach items="${fooListWrapper.fooList}" varStatus="i"><form:input path="fooList[${i.index}].name" type="text"/>    </c:forEach>    <button>submit</button></form:form>
