This article mainly explains "the realization method of apache shardingsphere transaction". The content of the explanation in the article is simple and clear, and it is easy to learn and understand.

Local transaction

TransactionTypeHolder.set (TransactionType.LOCAL)

Connection.setAutoCommit (true)

Statement.executeUpdate ("update user set name='kk' where id = 1")

Connection.commit () or commit.rollback ()

Put the transaction type in Threadlocal, default Local, so this sentence can be omitted

Execute setAutoCommit (true) on all ShardingConnection cached real Connection

Cache this operation in the jdbcMethodInvocations of ShardingConnection

During execution, if you need to create a new real Connection, setAutoCommit (true) will also be executed on the new Connection.

Performing setAutoCommit (true) in a new connection is achieved through jdbcMethodInvocations

New connections will also be cached

Commit or rollback is also performed on the real Connection of all ShardingConnection caches

DataSource dataSource = ShardingDataSourceFactory.createDataSource (datasourceMap, shardingRuleConfig, pros); Connection connection = null; try {connection = dataSource.getConnection (); connection.setAutoCommit (false); Statement statement = connection.createStatement (); statement.executeUpdate ("update user set name = 'meichaofeng' where ex_id = 201"); connection.commit (); statement.close () Connection.close ();} catch (SQLException e) {try {connection.rollback ();} catch (SQLException E1) {e1.printStackTrace () }} Thank you for your reading.
