在easypoi的实体注解中，例如如下的注解，要怎样才能在nutz的model上生效了？

    @ExcelTarget("courseEntity")
    public class CourseEntity implements java.io.Serializable {
    /** 主键 */
    private String id;
    /** 课程名称 */
    @Excel(name = "课程名称", orderNum = "1", needMerge = true)
    private String name;
    /** 老师主键 */
    @ExcelEntity(id = "yuwen")
    @ExcelVerify()
    private TeacherEntity teacher;
    /** 老师主键 */
    @ExcelEntity(id = "shuxue")
    private TeacherEntity shuxueteacher;

    @ExcelCollection(name = "选课学生", orderNum = "4")
    private List<StudentEntity> students;

因为导入后的内容是直接和实体类映射的，例如：

    ImportParams params = new ImportParams();
    params.setTitleRows(2);
    params.setHeadRows(2);
    //params.setSheetNum(9);
    params.setNeedSave(true);
    long start = new Date().getTime();
    List<CourseEntity> list = ExcelImportUtil.importExcel(new File(
            "d:/tt.xls"), CourseEntity.class, params);

@wendal 嗯，是我导入文件弄错了，还想为啥没生效！
