struts2中如何把request变成全局变量

Question

目前每一个方法都要写一遍

HttpServletRequest request = ServletActionContext.getRequest();

HttpServletResponse response = ServletActionContext.getResponse();

HttpSession session = request.getSession();

感觉好烦啊,怎么才能变成全局的呢

Answer 1

创建一个工具类，提供静态方法返回，如public static HttpServletRequest getRequest(){    return ServletActionContext.getRequest();}使用时直接 类名.getRequest();

Answer 2

写一个基类 然后所有的action都继承它
