Type attribute of struts2 result

Currently, only the following three types are used.

Chain:

Statement: <result name = "success" type = "chain"> nextaction </result>

The slash (/) is not added before nextaction. the value set in the request in the previous action can be obtained in nextaction.

Redirect:

Statement: <result name = "success" type = "Redirect"> nextaction </result>

You can add or remove a slash before nextaction. the value set in the request in the previous action is lost and cannot be obtained in nextaction.

However, you can use 【?] Use [&] instead of [& amp ;]

<Result name = "success" type = "Redirect"> nextaction? Nextform. Property =$ {currentform. Property} & amp; nextform. Property =$ {current. Property} </result>

Nextaction must have the get and set methods of nextform. If it is an attribute, it must also have the get and set methods to get the value.

Private nextform = new nextform ();
Public nextform getnextform (){
Return nextform;
}
Public void setnextform (nextform ){
This. nextform = nextform;
}

Redirectaction:

Statement: <result name = "success" type = "redirectaction"> nextaction </result>

The slash (/) is not added before youraction. the value set in the request in the previous action is lost and cannot be obtained in nextaction.

However, you can use 【?] Use [&] instead of [& amp ;]

<Result name = "success" type = "Redirect"> nextaction? Nextform. Property =$ {currentform. Property} & amp; nextform. Property =$ {current. Property} </result>

Nextaction must have the get and set methods of nextform. If it is an attribute, it must also have the get and set methods to get the value.

Private nextform = new nextform ();
Public nextform getnextform (){
Return nextform;
}
Public void setnextform (nextform ){
This. nextform = nextform;
}

Note: The difference between redirect and redirect-action

I. using Redirect requires a suffix. Using redirect-action does not require a suffix. However, in actual use, redirect does not require a suffix. In the same package, different packages have not been tried.
2. The value of type = "Redirect" can be transferred to actions in other namespaces, while redirect-action can only be transferred to actions under the same namespace, so it can be omitted. the suffix of the action directly writes the name of the action.
