In Spring Boot, the PlatformTransactionManager is an interface provided by Springs transaction management framework. It acts as an abstraction to manage transactions across different transactional resources such as databases, message queues, or other systems.

Typically, Spring Boot integrates with various transaction management frameworks, such as the Java Transaction API (JTA) for distributed transactions or the DataSourceTransactionManager for local database transactions.

Here is an example of how to use the PlatformTransactionManager with a local database transaction using Spring Data JPA:

@Service public class ExampleService { @Autowired private PlatformTransactionManager transactionManager; public void performTransaction() { TransactionDefinition transactionDefinition = new DefaultTransactionDefinition(); TransactionStatus transactionStatus = transactionManager.getTransaction(transactionDefinition); try { // Perform database operations // ... transactionManager.commit(transactionStatus); } catch (Exception e) { transactionManager.rollback(transactionStatus); } } }

In this example, the ExampleService class demonstrates the usage of the PlatformTransactionManager. The transactionManager bean is autowired into the class.

Inside the performTransaction() method, you create a TransactionDefinition object using DefaultTransactionDefinition to define the transaction properties.

You obtain a TransactionStatus object by calling transactionManager.getTransaction(transactionDefinition). This object represents the status of the transaction.

Within the try block, you perform your database operations. If an exception occurs, the catch block is executed, and transactionManager.rollback(transactionStatus) is called to roll back the transaction.

If no exception occurs, transactionManager.commit(transactionStatus) is called to commit the transaction.

Note that the exact implementation of the PlatformTransactionManager will depend on the transaction management framework you are using. Spring Boot provides integrations with various transaction managers, such as DataSourceTransactionManager for local database transactions or JtaTransactionManager for distributed transactions.

You can configure the appropriate PlatformTransactionManager bean based on your transactional requirements in your Spring Boot application context.
