Different kinds of actions in Struts.- The different kinds of actions are done by the following:
1. DispatchAction
2. ActionDispatcher
3. LookupDispatchAction.
DispatchAction :
- One of the built-in actions provided by the struts framework.
- The collection of related functions into a single Action is possible using this action.
- It allows eliminating the creation of multiple independent actions for each function.
ActionDispatcher :
- It is a helper class which dispatches to a method that is in Action.
- This class provides an alternative mechanism for using DispatchAction.
- With the help of various types of mechanisms, the ‘dispatching’ behavior can be easily implemented into an Action without inheritance of a particular super Action class.
LookupDispatchAction :
- The subclass mapped execute() method is dispatched by this abstract Action class. This process is useful where a HTML form has many clicks on submit buttons with the same name. The corresponding ActionMapping’s parameter property specifies the button name.Different kinds of actions in Struts.Dispatch Action :
- It dispatches to a public method that is named by the request parameter whose name is specified by the parameter property of the corresponding ActionMapping.
- This Action is useful when many similar actions need to be combined into a single Action class design simplification.
Forward Action and IncludeAction :
- These forward and include the context-relative URI specified by the parameter property of our associated ActionMapping.
