Spring MVC get multiple="；“真的”；在控制器中选择作为集合

我有Channel、Node和Channel\u节点类

public class Node {
    private String name;
    private String address;
    private Long idNode;
    private String description;
    private Organization organization;
    private Region region;
    private NodeType nodeType;
    private Integer bound;
    private Collection<ChannelNode> channelNodes;
    ....

public class Channel {
    private Long idChannel;
    private String name;
    private String description;
    private Long diameter;
    private Long capacity;
    private Long currentCapacity;
    private ChannelType channelType;
    private Long length;
    private Collection<ChannelNode> channelNodes;
    ....

public class ChannelNode {
    private Long idChannelNode;
    private String name;
    private Node node;
    private Channel channel;
    ....

我已经解决了这个问题：

@RequestMapping(value = "/create", method = RequestMethod.POST)
public String create(HttpServletRequest request, @Valid @ModelAttribute("channel") Channel channel,
        BindingResult result) {

    LOG.info(String.format("Create new channel: %s", channel));

    /*
     * if (result.hasErrors()) { return CHANNEL_ADD_VIEW; } else {
     */
    ChannelType channel_type = channelTypeService.getOne(Long.parseLong(request.getParameter("channelType")));
    channel.setChannelType(channel_type);

    List<ChannelNode> channelNodes = new ArrayList<ChannelNode>();
    ChannelNode channel_node;

    String[] channel_nodes = request.getParameterValues("channelNodes");

    for (String id_node : channel_nodes) {

        channel_node = new ChannelNode();
        channel_node.setNode(nodeService.getOne(Long.parseLong(id_node)));
        channel_node.setChannel(channel);
        channelNodes.add(channel_node);
    }

    channel.setChannelNodes(channelNodes);

    channelService.create(channel);

    return CHANNEL_LIST_VIEW_REDIRECT;
    // }

}

@RequestMapping（value=“/create”，method=RequestMethod.POST）
公共字符串创建（HttpServletRequest请求，@Valid@ModelAttribute（“通道”）通道，
BindingResult（结果）{
LOG.info（String.format（“创建新频道：%s”，频道））；
/*
*if（result.hasErrors（））{return CHANNEL\u ADD\u VIEW；}else{
*/
ChannelType channel_type=channelTypeService.getOne（Long.parseLong（request.getParameter（“ChannelType”））；
通道。设置通道类型（通道类型）；
List channelNodes=new ArrayList（）；
信道节点信道节点；
String[]channel_nodes=request.getParameterValues（“channelNodes”）；
用于（字符串id_节点：通道_节点）{
channel_node=新ChannelNode（）；
channel_node.setNode（nodeService.getOne（Long.parseLong（id_node））；
通道\节点设置通道（通道）；
channelNodes.add（channel_节点）；
}
channel.setChannelNodes（channelNodes）；
创建（频道）；
返回通道\列表\视图\重定向；
// }
}

@RequestMapping(value = "/create", method = RequestMethod.POST)
public String create(HttpServletRequest request, @Valid @ModelAttribute("channel") Channel channel,
        BindingResult result) {
