?当数据库表的主键使用mysql的自增ID时,获取一条刚插入的记录的ID可以?使用:

rs = pstmt.getGeneratedKeys();
if(rs.next()) {
??????? personId = rs.getInt(1);
}

?

附程序中的一个例子:

?????

	public int addPerson(Person person) {
		int personId = 0;
		
		Connection conn = null;
		PreparedStatement pstmt = null;
		ResultSet rs = null;
		
		try {
			String sql = "INSERT INTO t_person(personname, gender, age, address, duty, phone, description, receivesms) VALUES(?, ?, ?, ?, ?, ?, ?, ?)";
			conn = DB.getConn();
			pstmt = DB.prepareStmt(conn, sql);
			pstmt.setString(1, person.getPersonname());
			pstmt.setString(2, person.getGender());
			pstmt.setInt(3, person.getAge());
			pstmt.setString(4, person.getAddress());
			pstmt.setString(5, person.getDuty());
			pstmt.setString(6, person.getPhone());
			pstmt.setString(7, person.getDescription());
			pstmt.setInt(8, person.isReceivesms() ? 1 : 0);
			
			pstmt.executeUpdate();
			
			rs = pstmt.getGeneratedKeys();
			if(rs.next()) {
				personId = rs.getInt(1);
			}
			
		} catch (SQLException e) {
			e.printStackTrace();
			
		} finally {
			DB.close(pstmt);
			DB.close(conn);
		}
		
		return personId;
	}
