Examples of usage scenariosBefore we know how to use @transactional, we must first understand what @transactional is used for. Here's a chestnut: for example, there are a lot of members in a department, both of which are stored in the departmental and member tables, and when you delete a department, suppose we delete the corresponding member by default. But in the execution of this situation may occur, we f

The management of things is essential for enterprise applications, so that anomalies can occur, and it also guarantees data consistency.Spring supports both programmatic transaction management and declarative transaction management.Programmatic transaction management uses Transactiontemplate or uses the underlying platformtransactionmanager directly. For programmatic transaction management, Spring recommends the use of transactiontemplate.Declarative transaction management is built on the AOP. T

@transactional in spring is based on the mechanism of dynamic agent, which provides a transparent transaction management mechanism, which is convenient and quick to solve the problems encountered in development.A general use is to comment on a method or interface or class by using the following code:@Transactional (propagation=propagation.not_supported)　　The propagation supports 7 different propagation mech

Create | Scripting business applications often need to have the ability to run scripts and components within a transaction. A transaction is a server operation that, even if it involves many steps (for example, ordering, viewing inventory, paying bills, and so on), can only return the success or failure of the operation as a whole. A user can create an ASP script that runs inside a transaction, and the entire transaction terminates if any part of the script fails. ASP transaction processing is

Features of 16.4.1 transactional replication Earlier we pointed out that the essence of replication is to copy data from the source database to the target database, but there is always a difference for different types of replication. From the specific content of replication, snapshot replication is the true meaning of data replication, regardless of the type of data received (such as the table deleted before rebuilding or delete the data in the table

MySQL version: mariadb 5.5.30 OS Version: CentOS 5.6 x86_64 From a line in the Network: "transactions are written into the binlog in the order of submission. MySQLserver is a statement that distinguishes different threads and maintains a transaction cache for each thread, every statement executed in the transaction is placed in the transaction cache. The cached content of the transaction is copied to the binlog and cleared when the transaction is committed." I agree with the above sentence. Next

In general, when we manipulate the persistence of multiple data objects in a single method, we typically succeed in doing this successfully with a transactional commit. By default, the database is in autocommit mode. Each statement is in a separate transaction, and if the execution succeeds, the transaction is implicitly committed ifExecution failure is an implicit rollback of the transaction. It is possible to use spring's @
