Questions tagged [spring-transactions]

Questions related to Spring's Transaction API (programmatic or declarative)

Comprehensive transaction support is among the most compelling reasons to use the Spring Framework. It provides a consistent abstraction for transaction management that delivers the following benefits:

  • Consistent programming model across different transaction APIs such as Java Transaction API (JTA), JDBC,
  • Hibernate, Java Persistence API (JPA), and Java Data Objects (JDO).
  • Support for declarative transaction management.
  • Simpler API for programmatic transaction management than complex transaction APIs such as JTA.
  • Excellent integration with Spring's data access abstractions.
