這是創(chuàng)建學生的實現(xiàn)：

@Override
public?void?create(Student?student)?{
????Connection?connection?=?null;
????PreparedStatement?preparedStatement?=?null;
????ResultSet?resultSet?=?null;
????String?sql?=?"insert?into?student?(name,?age)?values?(?,?)";
????try?{
????????connection?=?JDBCUtil.getConnection();
????????preparedStatement?=?connection.prepareStatement(sql);
????????preparedStatement.setString(1,?student.getName());
????????preparedStatement.setInt(2,?student.getAge());
????????preparedStatement.executeUpdate();

????}?catch?(Exception?e)?{
????????e.printStackTrace();
????}?finally?{
????????JDBCUtil.release(resultSet,?preparedStatement,?connection);
????}
}

這是單元測試：

@Test
public?void?create()?{
????StudentDAO?studentDAO?=?new?StudentDAOImpl();
????Student?student?=?new?Student();
????student.setName("趙六");
????student.setAge(26);
????studentDAO.create(student);
}
