批量操作执行前事件发送缺失

[hanahmily]

监听器执行前获得的消息数量比升级生成的事件少

问题复现步骤:

1. 增加监听器

DMLExecutionEventBus.register(new DMLExecutionEventListener() {
            @Override
            public String getName() {
                return "test";
            }
            
            @Subscribe
            @AllowConcurrentEvents
            public void subscribe(final DMLExecutionEvent event) {
               ......
            }
        });

2. 执行sql

String sql = "INSERT INTO `t_order`(`order_id`, `user_id`, `status`) VALUES (?,?,?)";
        try (
                Connection connection = shardingDataSource.getConnection();
                PreparedStatement preparedStatement = connection.prepareStatement(sql)) {
            preparedStatement.setInt(1, 3101);
            preparedStatement.setInt(2, 11);
            preparedStatement.setString(3, "BATCH");
            preparedStatement.addBatch();
            preparedStatement.setInt(1, 3102);
            preparedStatement.setInt(2, 12);
            preparedStatement.setString(3, "BATCH");
            preparedStatement.addBatch();
            preparedStatement.setInt(1, 3111);
            preparedStatement.setInt(2, 21);
            preparedStatement.setString(3, "BATCH");
            preparedStatement.addBatch();
            preparedStatement.setInt(1, 3112);
            preparedStatement.setInt(2, 22);
            preparedStatement.setString(3, "BATCH");
            preparedStatement.addBatch();
            int[] result = preparedStatement.executeBatch();
        }

期望的表现:

subscribe收到的事件的数量应该为8，4条 BEFORE类型，4条SUCCESS类型

观察到的表现:

subscribe收到的事件的数量应该为8，2条 BEFORE类型，4条SUCCESS类型
