SSH is Spring + struts + Hibernate an integration framework, is one of the more popular
a Web application framework.
Spring
Light weight -- from two aspects in terms of size and cost of the Spring are
lightweight.A complete Spring framework can in one size only 1MB multiple JAR files
released.And Spring required processing overhead is not worth mentioning.
Inversion of control -- Spring through a known as inversion of control (IoC)
technology promotes loose coupling.When using IoC, an object depend on other objects
will be passed in through passive way, but not the object of its own to create or find a
dependent object.You can think of IoC and JNDI instead -- not the object from the
container for dependent, but in different container object is initialized object request on
own initiative will rely on to it.
Aspect oriented programming -- Spring provides rich support, allowed by separating
the application's business logic and system level service cohesion
development.Application object only realize they should do -- complete business
logic.They are not responsible for other system level concerns.
Container -- Spring contains and management application object configuration and
life cycle, in this sense, it is a kind of container, you can configure each of your bean to
be created -- Based on a reconfigurable prototype (prototype), your bean can create a
single instance or every time when they are needed to generate a new examples -- and
how they are interrelated.However, Spring should not be confused with the traditional
heavyweight EJB container, they are often large and unwieldy, difficult to use.
Struts
Struts on Model, View and Controller are provided with the corresponding
components.
ActionServlet, this is Struts core controller, responsible for intercepting the request from
the user.
Action, this class is typically provided by the user, the controller receives from the
ActionServlet request, and according to the request to call the model business logic
method to processing the request, and the results will be returned to the JSP page
display.
