struts2 Action中获取request, response对象的方法
第一种方法：
ActionContext ctx = ActionContext.getContext();
HttpServletRequest request = (HttpServletRequest)ctx.get(ServletActionContext.HTTP_REQUEST);
HttpServletResponse response = (HttpServletResponse)ctx.get(ServletActionContext.HTTP_RESPONSE);
//ServletActionContext.APPLICATION;
//ServletActionContext.SESSION;
//ServletActionContext.PAGE_CONTEXT;
第二种方法：
实现 ServletRequestAware
public class TestAction implements ServletRequestAware{
/**---*/
public void setServletRequest(HttpServletRequest request) {
// 要复写这个方法
request.setAttribute("key","value");
}
}
public class TestAction implements ServletRequestAware{
/**---*/
public void setServletRequest(HttpServletRequest request) {
// 要复写这个方法
request.setAttribute("key","value");
}
}
第三种：更简单的一种。。
HttpServletRequest request = ServletActionContext.getRequest(); //相应的可以得到response
