What is Atomikos spring?
Atomikos is a lightweight transaction manager for Java that enables applications using distributed transactions to be self-contained. Essentially, our application doesn’t need to rely on a heavyweight component like an application server for transactions.
Does spring use JTA?
Spring Boot supports distributed JTA transactions across multiple XA resources by using either an Atomikos or Bitronix embedded transaction manager. JTA transactions are also supported when deploying to a suitable Java EE Application Server.
What is JTA in spring?
The Java Transaction API (JTA) is a specification that describes a standard global transaction monitor API for users. You may use the JTA API to work with global transactions in a standard way for the resource types that support it – commonly just JDBC and JMS.

What is DataSourceTransactionManager in spring?
public class DataSourceTransactionManager extends AbstractPlatformTransactionManager implements ResourceTransactionManager, InitializingBean. PlatformTransactionManager implementation for a single JDBC DataSource .
What is Bitronix?

What does @transactional do in spring?
At a high level, when a class declares @Transactional on itself or its members, Spring creates a proxy that implements the same interface(s) as the class you’re annotating. In other words, Spring wraps the bean in the proxy and the bean itself has no knowledge of it.
What does @transactional do in Java?
Transactional annotation provides the application the ability to declaratively control transaction boundaries on CDI managed beans, as well as classes defined as managed beans by the Java EE specification, at both the class and method level where method level annotations override those at the class level.
What is PlatformTransactionManager in spring?
PlatformTransactionManager implementations are defined like any other object (or bean) in the Spring Framework IoC container. This benefit alone makes Spring Framework transactions a worthwhile abstraction even when you work with JTA. Transactional code can be tested much more easily than if it used JTA directly.
What is @transactional in spring boot?
The @Transactional annotation is the metadata that specifies the semantics of the transactions on a method. We have two ways to rollback a transaction: declarative and programmatic. In the declarative approach, we annotate the methods with the @Transactional annotation.
Which spring Transactionmanager do you use when creating XA transactions?
Spring Boot supports distributed JTA transactions across multiple XA resources using either an Atomikos or Bitronix embedded transaction manager. JTA transactions are also supported when deploying to a suitable Java EE Application Server.
What is Narayana JTA?
Narayana is a transactions toolkit which provides support for applications developed using a broad range of standards-based transaction protocols: JTA. Web-Service Transactions. REST Transactions. STM.
Which is Spring Boot sample JTA atomikos project?
GitHub – atomikos/spring-boot-sample-jta-atomikos-logcloud: Sample project showing how easy it is to do XA with clustered, cloud-native transaction logging and recovery. Sample project showing how easy it is to do XA with clustered, cloud-native transaction logging and recovery.
Can you receive a spring message in atomikos?
We support most of the Spring demarcation attributes except PROPAGATION_NESTED since that one depends on the Spring DataSourceTransactionManager strategy (incompatible with JTA/XA). You can receive messages either with the Atomikos receiver sessions, or with the Spring message listener containers.
How to use spring bean in atomikos VM?
Also see JMX Instrumentation of Active Transactions for additional VM settings. The Spring Bean configuration of the class UserTransactionServiceImp described above can be used to set the Atomikos JTA properties.
How to do Xa with atomikos sample project?
Sample project showing how easy it is to do XA with clustered, cloud-native transaction logging and recovery. You can run as many instances of this application as you like: scale up and down dynamically or kill any node with your chaos monkey and XA recovery simply works (as long as at least one node is up).
