公开一个Mysql如何获得新插入Id的代码
原理:
在Mysql中同一个连接执行了insert语句，接着执行SELECT LAST_INSERT_ID()可以获得刚刚插入的自增。
下面公开一段相关的Java代码
/** * 执行插入操作并且获得新的Id * * @param dataSource * @param sql * @param params * @return * @throws SQLException */public static int insertAndGetId(DataSource dataSource, String sql, Object[] params)throws SQLException {Connection con = dataSource.getConnection();PreparedStatement pstmt = con.prepareStatement(sql);try {for (int i = 1; i <= params.length; i++) {pstmt.setObject(i, params[i - 1]);}pstmt.executeUpdate();ResultSet rs = pstmt.executeQuery("SELECT LAST_INSERT_ID()");rs.next();int newId = rs.getInt(1);rs.close();return newId;} finally {try {pstmt.close();} finally {con.close();}}}
