To ensure data consistency, we often need to introduce the transaction concept during programming. Transactions have four features: atomicity, consistency, isolation, and persistence.
There are two types of transactions: programmatic transactions and clear transactions. A programmatic transaction is to put the transaction processing in the program, while a declarative transaction is to operate through the configuration file or annotation.
There is a declarative transaction concept in
ObjectiveNovice Learning to Hibernate and spring integration, if there is no good tutorial examples, it is easy to get overwhelmed, this time will instinctively go to the network to find relevant examples. However, the network of case-level, some very old, some of the framework and integration of a lot, rarely meet their own development phase of the case, let people look at the big head. Here, I briefly int
debugging environment is complex. The essence is to create a language that increases learning costs.

Advantage A. Spring can effectively organize your intermediate layer objects. B. by reducing the cost of interface programming rather than class programming to almost none, spring can promote good programming habits. C.
Turn:1. Concept:Hibernate : Hibernate is an open source object-relational mapping framework that provides JDBC with a very lightweight object encapsulation that allows Java programmers to manipulate databases at will, using object programming thinking. Focus on the relationship between objects and objects.Mybatis:mybatis is an open source project for Apache Ibatis, which was migrated to Google code by the Apache Software Foundation in 2010 and renamed
It's been a long time since I looked at Hibernate and spring's release version. I want to upgrade my heart. The problem really came to a lot ... Record them. Spring to 3.1 is simple, delete the old package, add a new package, and then configure the Xsi:schemalocation version from 3.0 to 3.1 other basic can be run intact.

If you consider using Spring or Hibernate with Ibm®websphere®application server, this article will explain how to configure these frameworks for various WebSphere application server scenarios. This article is not an exhaustive review of any framework, but rather an important reference to help you successfully implement such scenarios. (Updates are made for the Spring

Struts2 + hibernate + spring Environment Construction
I have been learning SSH over the past few days. Some people say there is no need to learn frameworks for the sake of learning frameworks !! I think I am learning the framework for the purpose of learning the framework, but it is also the situation! For the time being, no matter what others say, learning this kind of thing is your own as long as you
For Java web Programmer, Java Three framework: Struts+hibernate+spring understanding must be indispensable, the following detailed talk about Java Three framework is mainly used to do wen applications.Three main frames: struts+hibernate+springThe three main frameworks of Java are used to make Wen applications.Struts is primarily responsible for displaying the pre
technical support for components) rather than directly controlling program code in non-traditional implementations, this transfer of control from program code to external containers is called "flip" [3]. DI is a more vivid explanation of IoC, that is, the container dynamically injects dependencies (such as constructor parameters, constructor objects, or interfaces) into components during runtime. Spring uses a set-value injection (using the Setter me
