UserAction：

package com.bjsxt.struts2.user.action;

import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport{
    
    private static final long serialVersionUID = -1223017903962609751L;

    public Integer type;
    
    public String execute(){
        System.out.println("type = " + this.type);
        if(type == 1) return SUCCESS;
        if(type == 2) return ERROR;
        else return "mainpage";
    }

    public Integer getType() {
        return type;
    }

    public void setType(Integer type) {
        this.type = type;
    }
}

名为 user 的 namespace 中并没有，mainpage的result，它回去找父package中的result，找到了global-result 中的 mainpage
