NodeJS Mysql事务无法与innodb表一起正常工作

Question

我的数据访问层如下所示：

Connection.ts

let mysql = require('mysql');
const config = require('../../dbConfig/dbconfig');
let connectionpool = mysql.createPool({
  host: config.connection.host,
  user: config.connection.user,
  password: config.connection.password,
  database: config.connection.database,
  connectionLimit: 1000,
  connectTimeout: 60 * 60 * 1000,
  aquireTimeout: 60 * 60 * 1000,
  timeout: 60 * 60 * 1000,
});

exports.getConnection = function (callback) {
  connectionpool.getConnection(callback);
};

DBfactory.ts

const _dbConnection =  require('./Connection');
/**
 * Factory abstraction for creating database connection
 */
class DbFactory {
  static create(callback) {
    let st;
    const sqltranscation = require('./SqlTransaction');
    _dbConnection.getConnection((err, connection) => {
          if (err) {
            console.log('ERROR: getConnection failed: err = ' + err);
          }
          st = new sqltranscation(connection);
          return callback(st);
        });
  }
}
export const databaseFactory = DbFactory;

SQLtransaction.ts

class SqlTransaction {
  connection;
  constructor(connection) {
    this.connection = connection;
  }

  query(query, params, callback) { // command
    this.connection.beginTransaction((err) => {
      this.connection.query(query, params, (error, result) => {
        if (error) {
           this.connection.rollback();
           console.log(error);
           return callback(null, error);
        }
        // console.log(result);
        return callback(result, null);
      });
    });
  }

  complete() {
    this.connection.commit((err) => {
      if (err) {
        console.log(err);
      }
      this.connection.release();
      return err;
    });
  }
}

module.exports = SqlTransaction;

问题是我使用单个连接执行多个语句，但是后一个查询由于错误而失败时，将自动提交第一个查询。基本上，交易未按预期进行。我做错什么了吗？
