前台的ajax方法
$.ajax({
type: "post",
url: prefix + "/addDo",
data:{"projectList" :$('#form-projectList-add').serialize(),"ids":json2},
success: function(r) {

                }
            });

后台的controller方法
@At
@POST
@Ok("json")
@Slog(tag="项目申请列", after="新增保存项目申请列 id=${args[0].id}")
public Object addDo(@Param("..") ProjectList projectList,String ids, HttpServletRequest req) {
try {
ProjectList pro = projectListService.insert(projectList);
return pro.getId();
} catch (Exception e) {
return Result.error("system.error");
}
}

我想同时传projectList和ids的值,我应该怎么写?
