Structs2 DMI dynamic method call, structs2dmi

The execute method is not required when the Action is executed.

You can use method = to set the method to be executed when configuring the Action in the accessory weizi'an,

You can also specify the dynamic method in the url (dynamic method call MDI)

Note:

The former generates too many actions.

For example, <action name = "user" class = "com. b510.hongten. UserAction" method = "add">

<Result>/user. jsp </result>

</Action>

<Action neme = "user" class = "com. b510.hongten. UserAction" method = "sub">

<Result>/user. jsp </result>

</Action>

...

</Action>

The latter can do this with only one action, just enter the method name in the url.

<Action name = "user" class = "com. b510.hongten. UserAction">

<Result>/user. jsp </result>

</Action>

During the call, we write the following in the url:

Http: // localhost: 1000/struts2_0500_actionMethod/user! Add

Http: // localhost: 1000/struts2_0500_actionMethod/user! Sub

In this way, a lot of actions are not needed.
