Best Practice Recommendation of Bitronix Transaction Manager :: Core in the Java Class Library
Bitronix transaction manager (Bitronix Transaction Manager) is an open source manager for Java that can automatically handle the submission and rollback of distributed transactions.The use of Bitronix transaction manager in the application can ensure the consistency and integrity of the data, while improving the performance and scalability of the application.
This article will introduce the best practice of the Bitronix transaction manager, including how to configure and use the transaction manager and write related code examples.
1. Introduce Bitronix dependencies
Add Bitronix dependencies to the project's pom.xml file to use the transaction manager in the application.The example code is as follows:
<dependency>
<groupId>bitronix.tm</groupId>
<artifactId>btm</artifactId>
<version>2.1.4</version>
</dependency>
2. Configure Bitronix transaction manager
Add Bitronix's transaction manager configuration to the application file.Configuration files can be a separate bitronix-config.properties file, or it can be the relevant part of the application file of the application.The example configuration is as follows:
bitronix.tm.serverId = myServer
bitronix.tm.journal.disk.logPart1Filename = ${btm.root}/btm1.tlog
bitronix.tm.journal.disk.logPart2Filename = ${btm.root}/btm2.tlog
bitronix.tm.resource.configuration = ${btm.root}/resources.properties
These configuration parameters specify the unique ID of the server, the path of the transaction log file, and the path of the resource configuration file.Through configuration files, the Bitronix transaction manager can be set for various custom settings.
3. Writing code example
The following is a simple example of using the Bitronix transaction manager:
import bitronix.tm.TransactionManagerServices;
import bitronix.tm.resource.jdbc.PoolingDataSource;
public class BitronixExample {
public static void main(String[] args) {
// Initialize transaction manager
TransactionManagerServices.getTransactionManager();
// Create a database connection pool
PoolingDataSource dataSource = new PoolingDataSource();
dataSource.setClassName("com.mysql.jdbc.jdbc2.optional.MysqlXADataSource");
dataSource.setUniqueName("myDataSource");
dataSource.setMaxPoolSize(10);
dataSource.setAllowLocalTransactions(true);
dataSource.getDriverProperties().put("user", "root");
dataSource.getDriverProperties().put("password", "root");
dataSource.getDriverProperties().put("URL", "jdbc:mysql://localhost:3306/mydb");
// Perform database operations in transactions
Transaction transaction = TransactionManagerServices.getTransactionManager().begin();
Connection connection = dataSource.getConnection();
// Perform the database operation ...
connection.commit();
// Submit a transaction and close the connection pool
transaction.commit();
dataSource.close();
}
}
In this example, first obtain the instance of the transaction manager through the method of the `TransactionManagerserVicesrvices.gettransactionManager () method.Then create a database connection pool and obtain the database connection execution of related operations in the transaction.Finally, submit a transaction and close the connection pool.
Please note that this is just a simple example.In practical applications, more complicated transaction processing and resource allocation may be involved.
Summarize
By using the Bitronix transaction manager, developers can simplify the management of distributed transactions to ensure the consistency and integrity of the data.This article introduces the best practice of the Bitronix transaction manager, including the basic steps and code examples of configuration and using the transaction manager.Developers can further allocate and customize according to their needs and actual situation.
