Jakarta EE 8中的自定义FORM身份验证:身份验证后无法离开登录页面 [英] Custom FORM authentication in Jakarta EE 8: can't leave login page after authentication

问题描述

• Java 11
• 雅加达EE 8
• Wildfly 20

我决定尝试使用一种名为"Custom FORM"的新身份验证机制.我在BalusC的书 Java EE 8中的JSF权威指南中看到了Java EE Security的身份验证.

I decided to give a try to the new authentication mechanism called "Custom FORM" authentication from Java EE Security that I saw in BalusC's book The Definitive Guide To JSF in Java EE 8.

我创建了一个简单的应用程序来对其进行测试，但该应用程序无法正常工作.问题在于，成功通过身份验证后，我没有重定向到欢迎页面，而是保留在登录页面中.好像应用程序无法识别我已通过身份验证.

I created a simple application to test it and it's not working. The problem is that after a successful authentication, I'm not redirected to the welcome page, I keep in the login page. It's as if the application didn't recognize that I'm authenticated.

login.xhtml (JSF登录页面)

    xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:au="http://desenvolvimento.br/autenticacao">
    
    <ui:define name="titulo">
        Login
    </ui:define>

    <ui:define name="conteudo">
        <au:erros />
        <div id="campos">
            <h:outputLabel value="User name:" for="userName" />
            <h:inputText id="userName" value="#{pagLogin.userName}" />

            <h:outputLabel value="Password:" for="password" />
            <h:inputSecret id="password" value="#{pagLogin.password}" />

            <h:commandButton value="Enter" action="#{pagLogin.authenticateUser}" />
        </div>
    </ui:define>
</ui:composition>

但是，当我单击 Enter 按钮时，我看到我确实得到了 AuthenticationStatus.SUCCESS ，但是我没有重定向到 start.xhtml 页，即使我尝试在浏览器地址栏中手动更改它也是如此.它使我能够重定向到登录页面.

But when I click on the Enter button I saw that I really get an AuthenticationStatus.SUCCESS, but I'm not redirected to the start.xhtml page, even if I try to change it in the browser address bar manually. It keeps me redirecting to the login page.

在AuthenticationStatus result = executeUserAuthentication();之后，如果我输入以下代码:

After AuthenticationStatus result = executeUserAuthentication(); if I put this code:

boolean authenticated = ((HttpServletRequest) _externalContext.getRequest()).getUserPrincipal() != null;

变量authenticated是true.

也许只是缺少了一点东西，但我不知道它是什么.

Maybe there's just a little thing missing, but I don't know what it is.

更新1

我注意到登录后，我也在应用程序服务器日志中得到此警告:

I noticed that I also get this warn in the application server log after login:

16:57:47,217 WARN  [org.jboss.weld.Servlet] (default task-2) WELD-000717: Unable to deactivate context org.jboss.weld.module.web.context.http.LazyHttpConversationContextImpl@56a54798 when destroying request HttpServletRequestImpl [ POST /autenticacao/login.xhtml ]

我不知道这是否与问题有关.

I don't know if this has something to do with the problem.

过去的时代，当 web.xml 中的<login-config>变得一切复杂，而j_security_check的却变得丑陋，却又变得工作时.

Missing old times when everything was complicated with <login-config> in web.xml and ugly with j_security_check, but WORKED.

更新2

我找到了解决方法.看评论.

I found a workaround. Look at the comments.

更新3

Sylvain Autran在这里创建了一个最小的工作示例:

Sylvain Autran created a minimal working example here:

使用CustomFormAuth和o:form无法正确转发登录

他正在使用Payara 5版本201和2020.2来执行他的示例.因此，我决定在Wildfly 20中克隆并执行使用@CustomFormAuthenticationMechanismDefinition的示例.当我在登录页面中单击 Submit 按钮时，出现此错误，即JSF实现中的NullPointerException:

He is using the Payara 5, versions 201 and 2020.2 to execute his example. So, I decided to clone and execute its example that uses @CustomFormAuthenticationMechanismDefinition in Wildfly 20. When i click the Submit button in the login page I get this error, a NullPointerException in the JSF implementation:

因此，在Wildfly 20中，而不是应用程序中，这似乎是一个问题.

So, it seems a problem in Wildfly 20, not the application.

推荐答案

我决定再次尝试使用@CustomFormAuthenticationMechanismDefinition注释.

I decided to give another try to the @CustomFormAuthenticationMechanismDefinition annotation.

我创建了一个 app 目录，并将 start.xhtml 放在其中.

I created an app directory and placed the start.xhtml inside it.

web.xml 文件的相关部分现在如下所示:

The relevant parts of the web.xml file now looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" version="4.0">
    <display-name>autenticacao-visao</display-name>

    <security-constraint>
        <web-resource-collection>
            <web-resource-name>restrict</web-resource-name>
            <url-pattern>/app/*</url-pattern>
        </web-resource-collection>
        <auth-constraint>
            <role-name>USER</role-name>
        </auth-constraint>
    </security-constraint>
    <security-constraint>
        <web-resource-collection>
            <web-resource-name>allowed</web-resource-name>
            <url-pattern>/app/resources/*</url-pattern>
        </web-resource-collection>
    </security-constraint>

    <security-role>
        <role-name>USER</role-name>
    </security-role>

    <welcome-file-list>
        <welcome-file>app/start.xhtml</welcome-file>
    </welcome-file-list>
</web-app>

然后，由于某种原因，该应用程序最终运行，我可以离开登录页面，并显示开始页面.

And after that, for some reason, the application finally worked, I could leave the login page and the start page is shown.

现在我面临另一个小问题:

Now I'm facing another little problem:

>成功登录后，SecurityContext.authenticate()返回AuthenticationStatus. SEND_CONTINUE，而不是AuthenticationStatus.SUCCESS

这篇关于Jakarta EE 8中的自定义FORM身份验证:身份验证后无法离开登录页面的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
