How does transaction management work in spring?
Transactions and Proxies.
At a high level, Spring creates proxies for all the classes annotated with @Transactional – either on the class or on any of the methods.
The proxy allows the framework to inject transactional logic before and after the running method – mainly for starting and committing the transaction..
Why is transaction management necessary?
Local transactions are easier to be implemented. Global transaction management is required in a distributed computing environment where all the resources are distributed across multiple systems. In such a case, transaction management needs to be done both at local and global levels.
What is a transaction explain with example?
A transaction can be defined as a group of tasks. A single task is the minimum processing unit which cannot be divided further. Let’s take an example of a simple transaction. Suppose a bank employee transfers Rs 500 from A’s account to B’s account.
How do you handle distributed transactions?
When there is a need to update data in two places as a result of one event, Eventual Consistency / SAGA approach is a preferable way of handling distributed transactions as compared to the two-phase commit. The main reason being two-phase commit does not scale in a distributed environment.
What is transaction management?
Transaction management [1, 2] refers to the tasks of processing multiple transactions issued by various clients of a database server in such a way that the ACID contract can be fulfilled, that is, the properties of atomicity, consistency preservation, isolation, and durability of each individual transaction can be …
What is declarative transaction management in Spring?
Declarative transaction management approach allows you to manage the transaction with the help of configuration instead of hard coding in your source code. This means that you can separate transaction management from the business code. You only use annotations or XML-based configuration to manage the transactions.
How do you manage transactions in spring Microservices?

What can you apply the Spring framework declarative transaction management to?
It can work with JDBC, JDO, Hibernate or other transactions under the covers, with configuration changes only. The Spring Framework enables declarative transaction management to be applied to any class, not merely special classes such as EJBs.
What is transaction in Spring framework with example?
Support for Declarative Transaction Management. In this model, Spring uses AOP over the transactional methods to provide data integrity. This is the preferred approach and works in most of the cases. Support for most of the transaction APIs such as JDBC, Hibernate, JPA, JDO, JTA etc.
What does @transactional annotation do?
So when you annotate a method with @Transactional, Spring dynamically creates a proxy that implements the same interface(s) as the class you’re annotating. And when clients make calls into your object, the calls are intercepted and the behaviors injected via the proxy mechanism.
What is @transactional in hibernate?
The transactional annotation itself defines the scope of a single database transaction. The database transaction happens inside the scope of apersistence context. The persistence context is in JPA the EntityManager , implemented internally using an Hibernate Session (when using Hibernate as the persistence provider).

Which annotation will enable declarative transaction management?
@Transactional provides annotation-based declarative transaction support which is similar to EJB container-managed transaction. With this annotation, we can specify transaction behavior to individual methods without coupling business logic with transaction code.
