java程序中调用数据库中的存储过程

public static void aa(String jobNo) throws Exception {
        String sql = "CALL databaseName.procedureName(?)";
        Connection conn = null;
        try {
            conn = getConnection();
            CallableStatement cs = conn.prepareCall(sql);
            cs.setString(1, jobNo);
            cs.execute();
           
        } catch (Exception ex) {
            ex.printStackTrace();
        } finally {
            if (conn != null) {
                conn.close();
            }
        }
    }
