Struts中List里嵌套Map

Action中的代码

	@Getter
	@Setter
	private List<Map> recordlist;
	@Getter
	@Setter
	private Map map;


public String records(){

	 recordlist =	studentService.records(uid);

		return SUCCESS;


	}


---------service
	public List<Map> records(int uid) {
		// TODO Auto-generated method stub
		return this.stdCourseDao.findStdCourseRecord(uid);

	}
----------dao


public List<Map> findStdCourseRecord(int uid ) {

		String sql = "select record.*,course.*,member.* from 7east_adminopencourse_record record ,7east_course course,uchome_member member where record.courseid=course.cid and record.userid=? and member.uid=record.adminuserid";
		Object[] args = new Object[] { uid };

		RowMapper argTypes = new RowMapper() {
			@Override
			public Object mapRow(ResultSet rs, int rowNum) throws SQLException {
				Map<String,Object> map = new HashMap<String,Object>();

				String  cname = rs.getString("cname");
				String  casetype = rs.getString("casetype");
				int  price = rs.getInt("price");
