我想将 Spring Security 可能性添加到我的 GWT 项目中。我决定先在一个简单的 GWT 程序中对其进行调试。但是每次打开网页时我都没有登录窗口，我得到一个错误：

HTTP ERROR: 503
SERVICE_UNAVAILABLE
RequestURI=/Securitydemo.html
Powered by jetty://

有我的配置：

只需检查您的类路径上是否有正确的库...

以前的答案

您想将登录与 GWT 应用程序分开吗？

如果是这样，如何为登录创建一个 JSP 页面和一个 servlet 来处理它？

这是执行此操作的 Spring 配置。

   <http auto-config="false" use-expressions="true">
    <intercept-url pattern="/login" access="permitAll" />
    <intercept-url pattern="/**" access="hasRole('ROLE_USER')" />
    <form-login login-page="/login" authentication-failure-url="/login" />
    <logout logout-url="/logout" />
    <session-management
        session-authentication-error-url="/login"
        session-fixation-protection="newSession">
        <concurrency-control max-sessions="1"
             error-if-maximum-exceeded="true" />
    </session-management>
   </http>

您可能还需要在<form-login>标签中添加 authentication-success-handler-ref，以便在用户进行身份验证时将其重定向到您的 GWT 应用程序。

第二种方法是在 GWT 级别处理登录并手动设置安全上下文。如果这是您选择的选项，请告诉我，我将发布一些代码示例。
