Action属性值决定物理视图资源

配置result元素时，可以使用属性名来配置指定视图资源。但是这个属性，必须是Action类里的属性.
Action类

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;    }}

struts.xml

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