The path to the architect 22nd Day Universal Framework Spring (iv) using STRUTS2

The writing of classes in 4.2 struts2

The action in Struts2 is a normal class, and its public method name is a specific action, which is equivalent to the dispatchaction in the original struts1, but it is more flexible.

For example: I have a button called addstudent, if you have a publicstring addstudent () method in the class of your action, then your action name for this button is called/addstudent.action (Magic Bar).

We correspond to "<action name=" Login "class=" org.sky.ssh.login.action.LoginAction ">" to see our login.action bar, the front of this < Actionname= "" > The thing behind it is that our web path is equivalent to "/login.action".
