Struts中取得Request和Response、Session的方法
（一）
public HttpServletRequest request = ServletActionContext.getRequest(); public HttpServletResponse response = ServletActionContext.getResponse(); public HttpSession session= request.getSession(); public ServletContext application =session.getServletContext();
（二）
private Map request;
private Map session;
private Map application;
public String login() {
request = (Map) ActionContext.getContext().get("request");
session = ActionContext.getContext().getSession();
application =ActionContext.getContext().getApplication();
request.put("name", "admin");
session.put("name", "admin");
application.put("name", "admin");
return SUCCESS;
}
（三）
public class LoginAction extends ActionSupport implements RequestAware, SessionAware, ApplicationAware{
private Map<String, Object> request;
private Map<String, Object> session;
private Map<String, Object> application;
public String login() {
request.put("name", "admin");
session.put("name", "admin");
application.put("name", "admin");
return SUCCESS;
}
@Override
public void setApplication(Map<String, Object> application) {
this.application = application;
}
@Override
public void setSession(Map<String, Object> session) {
this.session = session;
}
@Override
public void setRequest(Map<String, Object> request) {
this.request = request;
}
}
（四）
public class LoginAction extends ActionSupport implements ServletRequestAware{
private HttpServletRequest request;
private HttpSession session;
private ServletContext application;
public String login() {
request.setAttribute("name", "admin");
session.setAttribute("name", "admin");
application.setAttribute("name", "admin");
return SUCCESS;
}
@Override
public void setServletRequest(HttpServletRequest request) {
this.request = request;
this.session = request.getSession();
this.application = session.getServletContext();
}
}
