算是不常用的东西，java中的ResultSet转List

Posted 2020-09-10 是谁，把你带到我身边

import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class ListResult {

	private List<Map<String, Object>> dbRestlt;

	public ListResult(ResultSet rs) {
		setDBRestlt(rs);
	}

	private void setDBRestlt(ResultSet rs) {
		try {
			if (rs == null) {
				return;
			}

			ResultSetMetaData md = rs.getMetaData();
			int num = md.getColumnCount();
			dbRestlt = new ArrayList<>();
			while (rs.next()) {
				Map<String, Object> mapOfColValues = new HashMap<>(num);
				for (int i = 1; i <= num; i++) {
					mapOfColValues.put(md.getColumnName(i), rs.getObject(i));
				}
				dbRestlt.add(mapOfColValues);
			}
			rs.close();
		} catch (SQLException e) {
			e.printStackTrace();
		}
	}

	public List<Map<String, Object>> getListRestlt() {
		return dbRestlt;
	}
}
