Spring Learning (eight) Spring integration struts2

The integration principle of spring framework on struts and other presentation frameworks:
Use spring's IOC container to manage the action in struts for processing requests
Configure an action as a bean in an IOC container

Extension: Spring's integration Principle (encapsulation) of the persistence layer Framework/technology:
Provides a template-class package for the corresponding Technology/framework development process
Through the use of template classes, to achieve the traditional development process of "substitution."
Second, the integration method:
Plug-in mode
STRUTS2 also provides a plug-in configuration file to implement the Spring framework integration Struts-plugin.xml
Struts2-spring-plugin.jar
Third, the integration process
A Create a Web project, add STRUTS2 Framework support (import STRUTS2 to bring the required package and configure Filter in Web. xml)

b Web Project Add Spring Framework support (import the spring core layer jar package, and the package under the Struts2 file, configure the Listener Listener and container profile parameters in Web. xml)

Iv. Specific examples
The use of spring in Web engineering portals
Structure:

Page:

 <form action="login.action"method="post">        type="text"  name="loginname"/><br/>        type="password" name="password"/><br/>        type="submit"value="登录"/>    </form>
