How to use Seata distributed transactions?
Here are the basic steps for using Seata, an open-source distributed transaction solution, to address transactional consistency issues in distributed systems.
- Introducing Seata dependency: Add Seata dependency to the pom.xml file of the project.
- Setting up Seata: Create Seata configuration files, typically registry.conf, file.conf, and config.txt, each used to configure the registry center, transaction log storage, and Seata’s global configuration, respectively.
- Start Seata service: To start the Seata service in the project, you can download the Seata release package and run seata-server.bat (for Windows) or seata-server.sh (for Linux).
- Configure distributed transactions: Set up parameters related to distributed transactions in the project’s configuration file, such as data sources and transaction modes.
- Define global transaction: by adding the @GlobalTransactional annotation to the methods that require distributed transactions, it indicates that the method is a global transaction.
- Participants of distributed transactions: Configure services (such as databases, message queues, etc.) that need to participate in distributed transactions as Seata transaction participants.
- Start distributed transaction: Before calling services that require distributed transactions, start a distributed transaction by calling Seata’s begin() method.
- Submit or rollback transaction: At the end of a distributed transaction, commit or rollback the transaction by calling Seata’s commit() or rollback() method.
The above are the basic steps for implementing distributed transactions using Seata, and the specific usage may be adjusted and expanded according to the actual project circumstances.
