下面是使用自定義autenticationFilter securityContext.xml配置文件的例子(擴展AUTHENTICATION_PROCESSING_FILTER)和authenticationProvider。用戶認證數據由jdbc連接提供。配置適用於Spring Security 2.0。X

我想你需要使用PRE_AUTH_FILTER位置而不是AUTHENTICATION_PROCESSING_FILTER。此外,您可能想要查看本教程以瞭解Google AppEngine中的身份驗證的實現:http://blog.springsource.com/2010/08/02/spring-security-in-google-app-engine/ – Tal 2011-09-12 07:29:03
