方法1：
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;
方法2：
import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.struts2.interceptor.ServletRequestAware; import org.apache.struts2.interceptor.ServletResponseAware; import com.opensymphony.xwork2.ActionSupport; public class BaseAction extends ActionSupport implements ServletRequestAware,ServletResponseAware{ private HttpServletRequest request; private HttpServletResponse response; @Override public void setServletRequest(HttpServletRequest request) { this.request=request; } @Override public void setServletResponse(HttpServletResponse response) { this.response=response; } }
方法3：
HttpServletRequest request = ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();
三种方法各有千秋...
