Detailed explanation and comparison of spring transaction isolation and transaction propagation

Spring is the administrator in SSH, responsible for managing other frameworks and coordinating the work of various parts. Today, let's learn about spring's transaction management. Spring's transaction management is divided into declarative and programmatic. Declarative is to configure the spring configuration file; Programming is to write notes into the code.

The transaction configuration in the spring configuration file always consists of three parts: datasource, transactionmanager and proxy mechanism. No matter which configuration method is used, the general change is only the proxy mechanism. Datasource and transactionmanager only change according to the data access method. For example, when hibernate is used for data access, the datasource is actually sessionfactory, and the implementation of transactionmanager is hibernate transaction manager.

Transaction isolation level of spring

You can adopt an appropriate isolation level according to your system's requirements for data, because isolation involves locking records in the database. The more strict the requirements for data positivity, the worse the concurrency performance.
