Question

我在Tomcat 8中使用JSF 2.2，并使用基于表单的身份验证。成功登录后，有时会正确显示主页。但是，有些时候，即使在成功登录后，也会显示登录页面。重新输入用户名和密码2-3次后，将显示主页。

XHTML页面如下所示：

托管bean看起来像这样：

package com.saptarshibasu.poc.login;

import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import javax.faces.context.FacesContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;

import com.saptarshibasu.poc.Utils;

@ManagedBean
public class Login {
protected String user;
protected String pwd;

@ManagedProperty(value="#{utils}")
private Utils utils;

public Utils getUtils() {
    return utils;
}

public void setUtils(Utils utils) {
    this.utils = utils;
}

public String getUser() {
    return user;
}

public void setUser(String user) {
    this.user = user;
}

public String getPwd() {
    return pwd;
}

public void setPwd(String pwd) {
    this.pwd = pwd;
}

public String login() {
    HttpServletRequest origRequest = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext()
            .getRequest();
    try {
        if(origRequest.getUserPrincipal()==null)
        {
            origRequest.login(user, pwd);
        }
        return "/pages/home.xhtml?faces-redirect=true";
    } catch (ServletException e) {
        FacesContext context = FacesContext.getCurrentInstance();
        FacesMessage fMessage = new FacesMessage(context.getApplication().getResourceBundle(context, "msg").getObject("login_err_message").toString());
        fMessage.setSeverity(FacesMessage.SEVERITY_ERROR);
        context.addMessage(utils.findComponent("username").getClientId(), fMessage);
        return null;
    }

}
}
