struts2使用随笔

获得request等对象

通过ServletActionContext获得

HttpServletRequest request = ServletActionContext.getRequest();  

另一种方法，通过实现相关接口，依赖注入获得

public class ParamGet extends AbstractInterceptor
        implements ServletRequestAware, ServletResponseAware, ServletContextAware {
    public HttpServletRequest servletRequest;
    public ServletContext servletContext;
    public HttpServletResponse servletResponse;
}
