, 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

, setting Springtransactionsynchronizationmanager.initsynchronization (). It is only after this operation that we can later hibernate save or update, Allows hibernate callback to be initialized when the Spring springsessioncontext generates hibernatesession and further gets jdbcconnection from the connection pool//Create "Empty" Transaction:no actualtransaction,

Original address: http://lengyun3566.iteye.com/blog/1068998 Recently read "Spring Security3" a book, quite rewarding (see picture on the cover). Therefore, some of its content is translated into Chinese, for the electronic version of the content, I give up all rights. Before the translation, I have sent an e-mail to consult the original author's opinion, is now half a month, have not seen his reply.

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

(i) Integration of spring and hibernate frameworks key points of integration: (1) The data source is configured in the spring configuration file for use by the spring and hibernate frameworks; (2) The Hibernate.hbm.xml configuration file is no longer needed, and the

• 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. (1) Struts framework: Struts is open source software. The purpose of using struts is to help us reduc

Spring hibernate configuration conflict in AOP Spring2.0 hibernate3.1.x/hibernate3.2 When you use spring's AOP programming, you use these several lib: Asm-2.2.2.jar Asm-commons-2.2.2.jar Asm-util-2.2.2.jar Hibernate If you use Lib: Asm.jar Asm-attrs.jar where Asm-2.2.2.jar and Asm.jar exist class conflicts ... Using one or both of these, you may receive the

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

Before we talk about spring transaction management, let's think about how we do data manipulation in hibernate when we're not using spring. In Hibernate we do one operation at a time we have to open the transaction, then the data operation, and then commit the transaction, close the transaction, we do this because

Quick Start This article is a primer for developing Web applications based on spring, using the Struts MVC framework, the middle tier using spring, and the background using hibernate. This article contains the following elements: • Configure Hibernate and transactions • Load Spring's applicationcontext

For the SSH framework, the core is spring. 1Struts is only responsible for intercepting requests on the browser side (which can be understood to get request requests, that is, to get the request object.) The Request object contains information such as the form information that the user entered on the page , the currently logged on user , and so on, and maps the requests to the execution class. All the rest of the work is given to

How does hibernate work and why should I use it?Principle:1. Read and parse the configuration file2. Read and parse mapping information, create Sessionfactory3. Open Sesssion4. Create Transaction Transation5. Persistent operation6. Commit a transaction7. Close session8. Close SesstionfactoryWhy to use:1. The code for JDBC access to the database is encapsulated, which greatly simplifies the tedious repetitive code of the data access layer.2.
