java - Spring 3 集合绑定(bind)

Question

我如何将集合绑定(bind)到输入数据的表单(不用于显示)

Answer 1

例如对于 Set<Jokers>

protected void initBinder(HttpServletRequest request, ServletRequestDataBinder binder) throws Exception {
    binder.registerCustomEditor(
        Set.class,
        "[nameOfTheClassMemberItShouldGoto]",
        new CustomCollectionEditor(Set.class) {
            protected Object convertElement(Object element) {
                return (element == null ? null : getQueryService().getJoker(element.toString()));
            }
        }
    );
}

或类似于此
