前端收到的是一个list，“a,b,c,d,e,f”这样，但是想要得到“字段名1：a,字段名2：b,字段名1：c 字段名1：d,字段名1：e,字段名1：f,”的结果，不知道怎么写，请各位大佬教教我

@POST
	@Ok("json")
	@At
	@AdaptBy(type = JsonAdaptor.class)
	@Filters
	public Object check(@Param("projectId")String projectId, HttpServletResponse response) {		
		try {
			log.info("查询成功");
			Sql sql = Sqls.create("SELECT a.name,a.realname,b.name as projectName from sys_project_user c LEFT JOIN sys_user a on a.id = c.u_id LEFT JOIN sys_project b on b.id = c.p_id where b.id = @A");
			sql.params().set("A", projectId);
		    sql.setCallback(new SqlCallback() {
		        public Object invoke(Connection conn, ResultSet rs, Sql sql) throws SQLException {
		            List<String> list = new LinkedList<String>();
		            while (rs.next()) {
		                list.add(rs.getString("name"));
		            	list.add(rs.getString("realname"));
		            	list.add(rs.getString("projectName"));
		            }
		            return list;
		        }
		    });
		    dao.execute(sql);
		    return sql.getObject(String.class);
		} catch (Exception e) {
			log.info("查询失败");
			e.printStackTrace();
		}
		return Messager.instance(CommResultEnum.QUERY_FAIL).res();
