1>接口定义
List<Map<String,String>> changToMap(@Param("reqDto")Student reqDto);
2> xml
SELECT name ,score FROM t_student
3> 处理接口返回值
public class DBToMap { public static Map<String, String> listToMap(List<Map<String, String>> list, String key, String value) { ConcurrentHashMap<String, String> map = new ConcurrentHashMap<>(); for (Map<String, String> temp : list) { map.put(temp.get(key), temp.get(value)); } return map; } }
至于如何批量插入、更新或插入、分表批量更新等
