What are the steps in Java transaction processing?

In Java, transaction processing typically involves the following steps:

1. To obtain a database connection, you typically need to establish a connection with the database, often using JDBC or an ORM framework.
2. To start a transaction, you need to call the setAutoCommit(false) method on the database connection object before executing any database operations to disable automatic commit and initiate the transaction.
3. Performing database operations: executing the necessary database operations within a transaction, such as inserting, updating, or deleting data.
4. Determine transaction execution outcome based on the result of database operations to decide whether to commit or rollback the transaction.
5. Submit or rollback transaction: If all database operations are successful, commit the transaction by calling the commit() method of the database connection object; if any operation fails, rollback the transaction by calling the rollback() method.
6. Close the database connection: It is necessary to finally close the database connection and release resources.

By following the above steps, you can ensure that transactions are correctly handled in Java programs, ensuring consistency and integrity in database operations.
