The application steps and examples of the JTA 1.1 framework in the Java class library

JTA (Java Affairs API) is a Java API for managing distributed transactions. It provides a unified programming model that enables developers to easily coordinate and manage affairs in a distributed environment.The following is the steps and examples of the JTA 1.1 framework applied in the Java class library. 1. Import related class libraries To use the JTA 1.1 framework, you need to import the related class libraries under the Javax.transaction package in the project.You can add the following dependencies in Maven or Gradle: <!-Maven dependency item-> <dependency> <groupId>javax.transaction</groupId> <artifactId>jta</artifactId> <version>1.1</version> </dependency> groovy // Gradle dependencies implementation 'javax.transaction:jta:1.1' 2. Get the transaction manager In the code, you first need to obtain an example of a transaction manager.The transaction manager is responsible for the life cycle of management affairs, and provides a set of operations to start, submit or roll back.You can get the TransactionManager instance in the following ways: import javax.transaction.TransactionManager; import javax.transaction.Transaction; TransactionManager manager = com.arjuna.ats.jta.TransactionManager.transactionManager(); 3. Starting affairs Once you get a transaction manager instance, you can use it to start a new transaction.Use the Begin () method to start a new transaction and return a transaction object, which can be used for subsequent transactions.The following is an example of a starting transaction: // Get the transaction manager TransactionManager manager = com.arjuna.ats.jta.TransactionManager.transactionManager(); try { // Starting transaction manager.begin(); // Perform database operations or other operations in transactions // Submit a transaction manager.commit(); } catch (Exception e) { // Treatment abnormalities and roll back transactions manager.rollback(); e.printStackTrace(); } 4. Do transaction operation You can perform any database operations or other operations that need atomic operations in transactions.These operations can use JDBC for database reading and writing, call EJB, or send messages with JMS.In affairs, all operations are considered a unit, either all successfully submitted or rolled back.The following is an example of database operation in transactions: // Get the transaction manager TransactionManager manager = com.arjuna.ats.jta.TransactionManager.transactionManager(); Connection connection = null; try { // Starting transaction manager.begin(); // Get the database connection connection = getDatabaseConnection(); // Execute the database operation Statement statement = connection.createStatement(); int rowsAffected = statement.executeUpdate("UPDATE users SET name = 'John' WHERE id = 1"); // Submit a transaction manager.commit(); } catch (Exception e) { // Treatment abnormalities and roll back transactions manager.rollback(); e.printStackTrace(); } finally { // Close the database connection closeDatabaseConnection(connection); } These steps provide the basic process of managing distributed transactions using the JTA 1.1 framework in the Java library.By obtaining transaction managers, starting transactions, executing transactions, and submitting or rolling, you can ensure that the consistency and reliability of transaction in the distributed environment.
