IBatis一对多嵌套查询

1)类

 public class AppData
    {
       // public int ModuleId { get; set; }
        public int DataId { get; set; }
        public int DataSequence { get; set; }
        public string ContentValue { get; set; }
    }
    public class AppModuleJoin
    {
        //public int PageId { get; set; }
        public int ModuleId { get; set; }
        public IList<AppData> DataList { get; set; }
        //public int DataId { get; set; }
        //public int DataSequence { get; set; }
        //public string ContentValue { get; set; }
    }
    public class AppModule
    {
       //public int PageId { get; set; }
        public int ModuleId { get; set; }
     
        //public int DataId { get; set; }
        //public int DataSequence { get; set; }
        //public string ContentValue { get; set; }
    }
    public class AppPageJoin
    {
        public int PageId { get; set; }
        public IList<AppModuleJoin> ModuleList { get; set; }
    }
    public class AppPage
    {
        public int PageId { get; set; }
       
    }

在调用中

 public IList<AppPageJoin> QueryData()
        {
            ISqlMapper mapper = _sqlMap;
            IList<AppPageJoin> ListPerson = mapper.QueryForList<AppPageJoin>("QueryData", null);  //这个"SelectAllPerson"就是xml映射文件的Id
            return ListPerson;
        }
