### Error updating database.  Cause: org.sqlite.SQLiteException: [SQLITE_BUSY_SNAPSHOT] Another database connection has already written to the database (database is locked)

Environment (please complete the following information):
windos 7
jdk 1.8

<dependency>
     <groupId>org.xerial</groupId>
    <artifactId>sqlite-jdbc</artifactId>
    <version>3.39.3.0</version>
</dependency>

Additional context
When my Java program performs database operations, I always add a global synchronized lock, but only for delete, insert, and update operations.

for example：

  synchronized (SynchronizedBaseDao.class) {
            return super.updateOrderStatus(orderKey, orderStatus, actionTime);
        }

i use HikariDataSource and set one connection

       HikariDataSource dataSource = new HikariDataSource();
            dataSource.setJdbcUrl(url);
            dataSource.setMaximumPoolSize(1);
            dataSource.setMinimumIdle(1);
            dataSource.setConnectionTimeout(50000);

[neoxpert]

The "new" problem looks like a usage problem or issue within MyBatis' configuration.

By default all connections returned from a HikariDataSource have autoCommit be set to true (Doc). That is causing the shown stacktrace. Try and set the default value for autoCommit to false on the dataSource, or if you are passing connections around manually, you can just set the autoCommit to true on a certain connection.
