嗨，我开发了小型 Web 应用程序，所有功能都可以正常工作，但是当我按下浏览器后退按钮时，它会显示上一页，如果您执行或单击任何操作按钮，它将调用并执行该操作如何防止用户看到下面是我的动作类和struts配置文件
public class LoginAction extends ActionSupport implements ModelDriven, SessionAware, ServletRequestAware {
private static final long serialVersionUID = -3197657749784237381L;
@SuppressWarnings("unchecked")
private Map session;
private HttpServletRequest request;
private LoginBean logBean = new LoginBean();
public LoginAction() {

return logBean;

this.logBean = logBean;

this.session = session;
}
/* public static Log getLOG() {
return LOG;

public static void setLOG(Log LOG) {
ActionSupport.LOG = LOG;
}
*/
public void setServletRequest(HttpServletRequest request) {
this.request = request;
}
public String execute() {
return SUCCESS;

public String verifyLogin() {
String target = "";
LoginDB logDB = new LoginDB();
UserBean ub = new UserBean();
String ipAddress = request.getRemoteAddr();
ub = logDB.verifyLogin(logBean.getLoginID(), logBean.getPassword());
if (ub.getInvalid().equals("1")) {
if (ub.getActive() != 0) {
session = ActionContext.getContext().getSession();
session.put("userBean", ub);
target = SUCCESS;
}
else {
addActionError("Your status is inactive!!!Please Contact Admin Or Activate Link");

if (true) {

我的注册班
public String execute() throws SQLException, ClassNotFoundException {

if(Mail()==1)

注意 ，正如您在我注销后看到的那样，我正在清除会话变量，但是如果用户单击返回它会显示注册页面，并且如果他单击注册按钮它将执行注册操作，所以任何人都可以告诉我如何防止在注销后执行该操作即使他单击任何操作事件按钮，它也应该将其重定向到登录页面。
