, the sample code is as follows: @Repositorypublic interface UserRepository extends JpaRepository2. The implementation class does not need to be explicitly implemented UserRepository , as long as it is named UserRepositoryImpl .The advantage is that there is no need to rewrite a method that does not require writing SQL or SQL statements that are not complex (using @Query annotations can be implemented).For methods that need to be judged and spliced into query conditions, we can override the

components. The Spring dao:jdbc DAO Abstraction Layer provides a meaningful exception hierarchy that can be used to manage exception handling and error messages thrown by different database vendors.

When learning a new content, I will look for some examples. However, some examples seem incomplete, some SQL table creation statements do not exist, and sometimes there is no jar package. I feel like, there are a lot of obstacles for beginners, So I first put the directory structure of the project out, then put the SQL tabulation statement, and finally put the source code: Directory structure: 2. Table creation statement: MySQL database, test databas

Long long ago. I've heard about SSH. At first, I thought it was a thing, the details are unknown, always think high-end atmosphere on the grade, after learning to find, not only tall, but also a low-key luxury has connotation, after a period of research and learning SSH framework basic principles and ideas. Finally grounded the gas. As the beginning of learning, a little bit of harvest, want to blog in the form of sharing with everyone, common progress, in the process of updating the blog will i

The previous blog has explained several common methods for configuring data sources in spring. Next, I will continue to explain this blog. After configuring the data source, how does the DaO layer access the database? Based on the recent project using the SSH2 framework, this paper analyzes and summarizes the two common methods for accessing the database at the DaO layer after spring and

• Definition: Java Three frameworks are mainly used for Wen applications. Struts is mainly responsible for the display of the presentation layer;Spring uses its IOC and AOP to handle the control business (responsible for the operation of the database);hibernate is primarily data persistence to the database.
