How to use Mybatis source code to analyze transaction management, in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

Mybatis transaction management

We can configure the implementation of the transaction manager in mybatis-config.xml

When the value is JDBC, the transaction management implementation class is JdbcTransaction, and the underlying layer uses the Connection of the database to manage transactions

When the value is MANAGED, the transaction management implementation class is ManagedTransactionFactory, but it is an empty implementation for transaction management, handing transaction management to an external container

JdbcTransaction

ManagedTransaction

Transaction management after integration with Spring

When mybatis and spring integrate to create TransactionFactory, if it is not set, it will be set to SpringManagedTransactionFactory

Org.mybatis.spring.SqlSessionFactoryBean#buildSqlSessionFactory

But when a transaction is actually executed, it is not usually executed by SpringManagedTransaction, because we usually leave the transaction to spring, and when we hand it over to spring, this.isConnectionTransactional=true, so commit and rollback are equivalent to empty implementation.

After the integration of mybatis and spring, transaction management is usually carried out by DataSourceTransactionManager in the spring framework.
