The integration method and precautions of the JTA 1.1 framework and the Spring framework
JTA (Java Affairs API) 1.1 framework and Spring framework are two frameworks commonly used in Java development. They can be well combined with management of distributed transactions.This article will introduce the integration method and precautions of the JTA 1.1 framework and the Spring framework, and provide relevant Java code examples.
1. Integrated method
1. Add Spring transaction manager: Integrate Spring's transaction manager into the application, you can perform a file or annotation method.In the Spring configuration file, the Bean and data sources of the transaction manager need to be configured.
@Configuration
@EnableTransactionManagement
public class AppConfig {
@Bean
public DataSource dataSource() {
// Configure the data source
...
return dataSource;
}
@Bean
public PlatformTransactionManager transactionManager() {
JtaTransactionManager transactionManager = new JtaTransactionManager();
transactionManager.setTransactionSynchronizationRegistry(jtaTransactionSynchronizationRegistry());
transactionManager.setUserTransaction(jtaUserTransaction());
return transactionManager;
}
@Bean
public TransactionManager jtaTransactionManager() {
return new com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionManagerImple();
}
@Bean
public UserTransaction jtaUserTransaction() {
return new com.arjuna.ats.internal.jta.transaction.arjunacore.UserTransactionImple();
}
@Bean
public TransactionSynchronizationRegistry jtaTransactionSynchronizationRegistry() {
return new com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionSynchronizationRegistryImple();
}
}
2. Configure JTA transaction manager: In Spring configuration files, the Bean of the JTA transaction manager needs to be configured in order to facilitate the management of distributed transactions.
@Configuration
public class JtaConfig {
@Bean
public UserTransactionManager userTransactionManager() throws Throwable {
UserTransactionManager userTransactionManager = new UserTransactionManager();
userTransactionManager.setForceShutdown(false);
return userTransactionManager;
}
@Bean
public UserTransactionImp userTransactionImp() throws Throwable {
UserTransactionImp userTransactionImp = new UserTransactionImp();
userTransactionImp.setTransactionTimeout(180);
return userTransactionImp;
}
@Bean(initMethod = "init", destroyMethod = "close")
public UserTransactionService userTransactionService() throws Throwable {
UserTransactionService userTransactionService = new UserTransactionService();
userTransactionService.setTransactionTimeout(180);
return userTransactionService;
}
}
3. Configuration of JTA transactions support: In the Spring configuration file, you need to enable annotations and scanning transaction annotations.
@Configuration
@EnableTransactionManagement
public class TransactionConfig {
@Bean
public JtaTransactionManager jtaTransactionManager() {
JtaTransactionManager jtaTransactionManager = new JtaTransactionManager();
jtaTransactionManager.setTransactionManager(jtaTransactionManager());
jtaTransactionManager.setUserTransaction(jtaUserTransaction());
return jtaTransactionManager;
}
@Bean
public TransactionManager jtaTransactionManager() {
return com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionManagerImple.getTransactionManager();
}
@Bean
public UserTransaction jtaUserTransaction() {
return com.arjuna.ats.internal.jta.transaction.arjunacore.UserTransactionImple.getUserTransaction();
}
@Bean
public TransactionSynchronizationRegistry jtaTransactionSynchronizationRegistry() {
return com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionSynchronizationRegistryImple.getTransactionSynchronizationRegistry();
}
}
2. Precautions
1. Configure data source: When using the JTA 1.1 framework with Spring, the data source is required correctly to ensure that distributed transactions can be executed normally.
2. Affairs manager configuration: In the JTA 1.1 framework, the correct transaction manager needs to be configured, including transactionManager, Usertransactions, and TransactionSyNChronizationRegization.
3. Edition compatibility: Make sure the JTA 1.1 framework and the Spring framework are compatible.It is recommended to use the latest version to obtain better functions and performance.
4. Note support: The configuration of the annotations and scanning transactions is very important to use @Transactions annotation in the code to manage transactions.
5. Abnormal treatment: When using distributed transactions, you need to pay attention to abnormal treatment and rollback operations to ensure that transactions can be submitted or rolled correctly.
In summary, through the correct configuration of the JTA 1.1 framework and the Spring framework, and follow the precautions, it can realize the management of distributed transactions and provide reliable transaction support for Java applications.
