Java applications use annotations to provide additional information about the code but do not impact a compiled code. According to a research study by Snyk in 2020 on the usage of the server-side web frameworks, 50% of the respondents have said they use Spring Boot, and 31% of the respondents use Spring MVC. Since its introduction in 2003, its advantages have made it one of the most dominant server-side frameworks among many organizations. If a given business use case needs to mix them, like when it has to parse a given statement, build a report, and save some results to the database, it’s best if the database transaction is started as late as possible.įor this reason, you could have a non-transactional gateway service, like the following class RevolutStatementService = Propagation.The Spring framework is a robust server-side framework for modern Java-based enterprise applications. In the Service layer, you can have both database-related and non-database-related services. The best way to use the Spring Transactional annotation The DAO (Data Access Object) or Repository layer requires an application-level transaction, but this transaction should propagate from the Service layer. The annotation belongs to the Service layer because it is the Service layer’s responsibility to define the transaction boundaries.ĭon’t use it in the Web layer because this can increase the database transaction response time and make it more difficult to provide the right error message for a given database transaction error (e.g., consistency, deadlock, lock acquisition, optimistic locking). What layer does the Spring Transactional annotation belong to? Normally, you’d use these attributes for one or more RuntimException classes for which you don’t want to roll back a given transaction. noRollbackFor and noRollbackForClassName – define one or more Throwable classes for which the current transaction will not be rolled back.By default, a transaction is rolled back if a RuntimException or an Error is thrown, but not if it throws a checked Exception. rollbackFor and rollbackForClassName – define one or more Throwable classes for which the current transaction will be rolled back.
