Action属性值决定物理视图资源

public class MyAction extends ActionSupport {
private String target;
private String tip;

public String execute(){
setTip("恭喜你跳转成功");
return "success";
}
public String getTarget() {
return target;
}
public void setTarget(String target) {
this.target = target;
}
public String getTip() {
return tip;
}
public void setTip(String tip) {
this.tip = tip;
}

}

<package name="default" extends="struts-default" namespace="/">
<action name="myAction" class="cn.action.MyAction">
<result>/${target}.jsp</result>
</action>
</package>
