Two actions in struts2 dynamically pass parameters, which are configured in struts. xml

1. For example:

When adding a department, click Save to go to the department list.

 

ADD teamAction: Adddepartmentaction

Show DepartmentAction: Listdepartmentaction

 

The Struts. xml configuration is as follows:

<Action name = "adddepartmentaction" class = "com. XK. Department. adddepartmentaction">
<Result name = "success" type = "Redirect"> listdepartmentaction. Action <result>
</Action>

<Action name = "listdepartmentaction" class = "com. XK. Department. listdepartmentaction">
<Result name = "success">/list. jsp </result>
</Action>
If you have other requirements, for example, after you click Save, you need to pass the ID (parentid) of the upper-level department to listdepartmentaction.

Modify the Struts. xml configuration:

<Action name = "adddepartmentaction" class = "adddepartmentaction">
<Result name = "success" type = "Redirect"> listdepartmentaction. Action? Parentid =$ {parentid} </result>
</Action>

<Action name = "listdepartmentaction" class = "listdepartmentaction">
<Result name = "success">/list. jsp </result>
</Action>

So how to obtain parentid =$ {parentid?

You need to configure a parentid attribute in adddepartmentaction, And the get () and set () methods must be available.
