The transaction processing system is very familiar to the database users, but if the transaction processing system is transferred from the database to the file system, it is estimated that many students will be helpless. In fact, support for file system operations transactions has been weak, regardless of library/framework, language, or file system level.See some file system operations alone (such as file renaming, deletion, etc.), they are atomic, but from the current situation, there are few s

Look at the code output below#include The second sentence has a copy construction, in fact the problem is to investigate deep copy and shallow copy. A shallow copy occurs when the copy is constructed.We can see from the Debug information:At this point PA and PB data point to the same piece of memoryThe data is "test"Once the delete PA has been executedAt this point the point is empty.An understanding of a pen question C + + copy constructor

Types of transaction management supported by springSpring supports two types of transaction management: Programmatic Transaction Management: This means that you manage transactions programmatically, giving you great flexibility, but difficult to maintain. Declarative Transaction Management: This means that you can separate business code from transaction management, and you only need to manage transactions with annotations and XML configurations. Spring

The atomic method provided by the Atomicinteger class allows this operation to be atomic, such as the Getandincrement () method, which atomically increments the current value by one, and other data types and reference variables can be similarly manipulated.12.
