无pojo怎么批量一次导入或更新多条数据到数据库
7 回复
@wendal 我们是excel导数据,用户身份证相同的执行更新,没有的执行新增,还有你那个是有pojo的情况才能用吧
不是的, map也可以的
List<NutMap> list = new ArrayList<NutMap>();
for (int i = 0; i < 10; i++) {
NutMap map = new NutMap();
map.setv("+*id", 0);
map.put("name", "abc_" + i);
list.add(map);
}
list.get(0).setv(".table", "t_pet");
dao.fastInsert(list);
for (NutMap map : list) {
log.debugf("id=%d, name=%s", map.get("id"), map.get("name"));
}
输出
