[ SpringMVC ] 往后台传集合json参数并在Controller层获取

前端

 /*数据封装在数组中*/ 
 groupList.push({
                selector: "select_"+(this.groupList.length),
                member:["张倩","李晶晶"],
                info:"负责根据专家组的建议和事件现场情况，迅速组织抢修力量、调用专用防护用品和专用工具进行抢修抢险。及时控制危险源，控制易燃、易爆。",
                name:"抢修排险组",
                groupId:-1,
                add:true
            });

/*post 请求方式：指定协议*/
  var groupConfigVO = this.groupList;
           $.ajax({
                type:"POST",
                url: globalHolder.request.savePlangroupConfig,
                async:false,
                dataType:"json",
                contentType:"application/json", // 指定这个协议很重要
                data:JSON.stringify(groupConfigVO),
                success:function(data) {

                }
            });

Controler层

集合内对象定义：

public class GroupConfigVO {

    private Integer groupId;

    private List<String> member;

    private String info;

    private String selector;

    private String name;

    private boolean add;

    public GroupConfigVO() {

    }

    public GroupConfigVO(Integer groupId, List<String> member, String info, String selector, String name, boolean add) {
        this.groupId = groupId;
        this.member = member;
        this.info = info;
        this.selector = selector;
        this.name = name;
        this.add = add;
    }
    //对应属性的setter和getter
    ...
}

利用List获取集合参数

    @ResponseBody
    @RequestMapping(value="/savePlangroupConfig",method= RequestMethod.POST)
    public RespMapJson savePlangroupConfig(@RequestBody List<GroupConfigVO> groupConfigVO) {
        //todo

        return new RespMapJson(ResultCode.SUCC.getValue());
    }

备注：

定义的对象一定要和传入的参数名一致！
