我正在使用GWT 2.4和Spring 3.1，我想用Spring Security保护我的应用程序。我一直在寻找没有单独 JSP 登录页面的仅 GWT 解决方案。我发现只有旧站点使用 JSP 进行登录，所以这个线程可能会导致以标准方式将 GWT 与 Spring Security 完全集成的解决方案。无论如何，如果有一个已经成功完成的参考，当然可以使用指向该参考的链接关闭该线程。

到目前为止，这是我的第一种方法：

应用程序上下文-security.xml：

<http auto-config="false" use-expressions="true" entry-point-ref="customAuthenticationEntryPoint">
    <intercept-url pattern="/ApplicationScaffold.html" access="permitAll" />
    <intercept-url pattern="/**" access="hasRole('ROLE_USER')" />
</http>

<beans:bean id="customAuthenticationEntryPoint" class="org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint" 
    c:loginFormUrl="/ApplicationScaffold.html" />

<!-- Configure Authentication mechanism -->
<authentication-manager alias="authenticationManager">
    <authentication-provider>
        ...
    </authentication-provider>
</authentication-manager>

ApplicationScaffold.html（我的应用程序是使用 Spring Roo 创建的）是我的起始页面，其中包含 GWT 登录页面。

网页.xml：

<display-name>securitytest</display-name>

<description>Roo generated application</description>

<servlet-mapping>
    <servlet-name>requestFactory</servlet-name>
    <url-pattern>/gwtRequest</url-pattern>
</servlet-mapping>

<session-config>
    <session-timeout>10</session-timeout>
</session-config>

该类CustomRequestFactoryServlet扩展RequestFactoryServlet了提供额外的构造函数来解决 Spring 服务，并且不应该与安全问题相关。

在 GWT 小部件上输入用户名和密码后，将调用登录服务（通过RequestFactory），该服务仅执行以下操作：

public String loginUser(String username, String password) {
    UsernamePasswordAuthenticationToken token = 
            new UsernamePasswordAuthenticationToken(username, password);

    Authentication authenticatedUser = authenticationManager.authenticate(token);
    SecurityContextHolder.getContext().setAuthentication(authenticatedUser);

    return username;

}

因此，当我输入像 .. /fooooooo这样的 URL 时，我希望我的应用程序将我重定向到登录页面 ( ApplicationScaffold.html )。但是只有浏览器地址栏中的 URL 被设置为 ../ApplicationScaffold.html并且没有其他任何事情发生。

我究竟做错了什么？

纯 GWT 解决方案：

  1. 根本不使用 http元素（来自配置命名空间的 http 标签）
  2. 定义您的 AuthenticationRpcService
  3. 添加 AuthenticationRpcService.authenticate(user,password) 方法
  4. 从 security-context.xml 注入 AuthenticationServiceImpl AuthenticationProvider bean

  5. 将 AuthenticationRpcService.authenticate(user,password) 实现为：

    User user = new User(login, password, true, true, true, true, new ArrayList<GrantedAuthority>());
Authentication auth = new UsernamePasswordAuthenticationToken(user, password,
        new ArrayList<GrantedAuthority>());
try {
    auth = this.authenticationProvider.authenticate(auth);
} catch (BadCredentialsException e) {
    throw new ClientSideBadCredentialsException(e.getMessage(), e);
}
SecurityContext sc = new SecurityContextImpl();
sc.setAuthentication(auth);

SecurityContextHolder.setContext(sc);

  6. 确保在处理每个 GWT RPC 调用期间执行 spring 安全过滤器链（以确保将 SecurityContext 填充到 SecurityContextHolder 中）。

  7. 使用 @RolesAllowed({ "ADMIN_ROLE", "USER_ROLE" }) 注释保护所有业务服务
  8. 准备您自己的可在客户端使用的 ClientSideAcessDeniedException
  9. 在 spring AcessDeniedException 的情况下，将 ClientSideAcessDeniedException 传播到客户端
  10. 在客户端通过 GWT.setUncaughtExceptionHandler 设置 UncaughtExceptionHandler

我发现使用 Spring Security 在 gwt 中可以保护的只是 RPC 调用，但就 gui 而言你不能。请记住，它们是 javascript，因此在安全配置中没有要定义的 url。这就是为什么所有示例都有 jsp 登录页面的原因。然后，您必须使用 userContext for frontend 来实现某种类型的客户端安全性。

您需要弄清楚为什么您的用户被视为匿名用户（stacktrace 中的第 77 行）。我想 Spring 然后发送另一个重定向（到登录），但 GWT 回调不知道如何处理 HTTP 302？
