The example in this article describes transaction management in spring. Share to everyone for your reference. The specific analysis is as follows:
Introduction to Transactions:
Transaction management is an essential technology in enterprise application development to ensure data integrity and consistency
A transaction is a series of actions that are treated as a separate unit of work. These actions are e

This example describes the basic management of spring beans. Share to everyone for your reference, specific as follows:
One, using setter method to complete dependency injection
The following are the beans and beans-config.xml files.

private String Helloword;
//... Omit getter, setter method
}

Recently studied spring + IBATIS. It is one thing to find examples of others, and to write a complete application is another matter. I'm fed up with the smattering code posted online.
Ibatis is a persistence framework that covers SQL procedures, although SQL statements need to be written by themselves. In addition, I think for beginners, the complete example is really important, otherwise I do not know if t

The Mapper method provided by mybatis is confusing: an interface class is provided, but the implementation class cannot be found. In fact, this interface mainly provides a list of method names and parameters. After the Mapper agent class extracts the information, this interface is useless and thus does not need to be implemented, it still uses sqlsession for operations. From the perspective of the sqlsession method, we can directly provide the method name and parameter information to omit this M
Using the underlying API: RedisConnection operation of Redis requires manual conversion of data ( String ), which requires most repetitive work and is inefficient; org.springframework.data.redis.core.RedisTemplate classes provide a high level of abstraction for interacting with Redis, which is responsible for serialization and connection management, encapsulating most of the repetitive work. And RedisTemplate is a thread-safe class.In addition, the template provides an operation view for handli
