best spring online training certification classes at india, canada
DESCRIPTION
The major purpose of spring online training will be to make J2EE easier to use and encourage good programming practice. It will this by empowering a POJO-based programming model which is appropriate in an extensive array of surroundings.So you will find no programs that are logging in spring, no distributed transaction coordinator, no connection pools. For exactly the same reason, we do not supply an O/R mapping level. There are excellent answers for this issue including Hibernate, Top Link and JDO.Springtime does plan to make present technologies more easy to work with. As an example, although we're not in the company of low level trade coordination, we do supply an abstraction layer over another trade strategy or JTA.http://www.ithubonlinetraining.com/spring-online-training/TRANSCRIPT

Introduction about spring
The Spring Framework is a Java platform that provides all-inclusive infrastructure support for Java programs that are developing. In order to concentrate on your use, the infrastructure is handled by spring.
Spring lets you construct programs from "plain old Java objects" (POJOs) and to implement business services non-invasively to POJOs. This ability applies to partial and complete Java EE and to the Java SE programming model.
Architectural benefits of Spring
Spring can effectively organize your middle tier objects, whether or not you choose to use EJB. Spring takes care of plumbing that would be left up to you if you use only Struts or other frameworks geared to particular J2EE APIs. And while it is perhaps most valuable in the middle tier, Spring's configuration management services can be used in any architectural layer, in whatever runtime environment.
Architectural benefits of Spring
Spring can eliminate the proliferation of Singletons seen on many projects. In my experience, this is a major problem, reducing testability and object orientation.
Spring can eliminate the need to use a variety of custom properties file formats, by handling configuration in a consistent way throughout applications and projects. Ever wondered what magic property keys or system properties a particular class looks for, and had to read the Javadoc or even source code? With Spring you simply look at the class's JavaBean properties or constructor arguments. The use of Inversion of Control and Dependency Injection (discussed below) helps achieve this simplification.
Architectural benefits of Spring
Spring can facilitate good programming practice by reducing the cost of programming to interfaces, rather than classes, almost to zero.
Spring is designed so that applications built with it depend on as few of its APIs as possible. Most business objects in Spring applications have no dependency on Spring.

Benefits of spring
Works on POJOs. Hence easier for dependency injection / injection of test data.
With the Dependency Injection(DI) approach, dependencies are explicit and evident in constructor or JavaBeans properties.
Enhances modularity. Provides more readable codes.
Provides loose coupling between different modules.
Disadvantages of spring
Complex: One of the major criticisms faced by the Spring framework is that it is complex! No so clear focus, more than 2400 classes, 49 other tools and tons of the other things make it complicated for the developers.
Longer Learning Curve: If you’re a newbie developer, it would be quite difficult for you to learn Spring framework. The main reason behind this is a whole host of new programming methods and detailing require understanding how to set up the Spring XML configuration file.
