Upgrading from 3 to 4 - how to find out if Transaction is active?

[rdehuyss]

Hi,

I'm Ronald, the creator of JobRunr, a distributed job scheduling library that supports Micronaut.

I'm currently trying to upgrade to Micronaut 4 but having some difficulties - I tried finding a solution in the docs and the Micronaut Data source code but didn't find it yet.

For some functionality, I need to know whether a transaction is active. The code below worked in v3. What would be the equivalent in v4?

@Override
    public Connection create(DataSource dataSource) throws SQLException {
        if(TransactionSynchronizationManager.isActualTransactionActive()) {
            try {
                Connection connection = DataSourceUtils.getConnection(dataSource);
                return new MicronautTransactionAwareConnection(connection);
            } catch (CannotGetJdbcConnectionException e) {
                throw (SQLException) e.getCause();
            }
        }
        return dataSource.getConnection();
    }

Thanks!

You might want to inject ‘TransactionOperations’ and call find status or use ‘ConnectionOperations’

Thanks @dstepanov for the quick reply! Will this also work in a multithreaded application (is it thread-safe)?

The javadoc does not mention anything about multithreading.

Yes, the propagated context is stored in the thread local in the same way as before
