Java EE Framework Spring

The Spring framework is an open-source Java/java EE full-featured Stack (FULL-STACK) application framework that is released as an Apache license, as well as a ported version on the Qkxue.net platform. The framework is based on the code in the Expert one-on-one Java EE Design and development (ISBN 0-7645-4385-7) book, originally developed by Rod Johnson and Juergen Hoeller. The Spring Framework provides a simple development approach that avoids the large number of property files and helper classes that can cause the underlying code to become cluttered.

Key features included in Spring:

The powerful JavaBeans-based practice configuration management with the inversion of control,ioc principle, the basic tutorial qkxue.net that makes the application build faster and easier.

A core Bean factory that can be used in different operating environments, from applets to Java EE.

The generalized abstraction layer of a database transaction, allowing the declarative (declarative) transaction manager to simplify the partitioning of the transaction so that it is not related to the underlying.

The built-in generalized policy for JTA and a single JDBC data source makes Spring's transactional support do not require a Java EE environment, as opposed to a generic JTA or EJB CMT.

The JDBC abstraction layer provides a targeted exception level (no longer extracting the original code from the SQL exception), simplifying error handling and greatly reducing the amount of coding the programmer has. When using JDBC again, you don't have to write another ' terminate ' (finally) module. and JDBC-oriented exceptions match the spring Universal Data Access object exception level.

Integrates with Hibernate,jdo and IBATIS SQL Maps in the form of resource containers, DAO implementations, and transaction policies. Many typical hibernate integration problems have been solved by using numerous flip control convenience features for full support. All of these comply with the spring general transaction and generic data Access object exception level specification.

Flexible MVC Web application framework based on core Spring features. Rookie tutorial Qkxue.net that the developer will have a high degree of control over the framework through the policy interface, so the framework will adapt to a variety of rendering (View) technologies, such as Jsp,freemarker,velocity,tiles,itext and POI. It is worth noting that the Spring middle tier can easily be combined with any MVC framework-based web layer, such as struts,webwork, or Tapestry.

Provides aspect-oriented programming frameworks for services such as transaction management.

When designing an application model, the MVC pattern (for example, struts) is often difficult to give a straightforward framework structure. Spring has the ability to make this part of the job easier. Program developers can use spring's JDBC abstraction layer to redesign those complex framework structures.
