如何在grails中使用XML用户文件实现身份验证？
作为 grails 的新手，我想了解如何使用 XML 用户文件对用户进行身份验证？例如：只有当凭据（用户名和密码）与 XML 文件中的凭据匹配时，用户才能登录。谁能帮忙举个简单的例子。我基本上想知道要编写哪些附加类或需要修改。请指导！！！
Being a newbie to grails, I want to learn how to authenticate users using an XML users file? For ex: A user is able to login only when the credentials(username & password) match with the one in XML file. Can anyone please help giving a simple example. I basically want to know what additonal classes are to be written or require modifications. Please guide!!!

Spring Security Core 插件 对用户身份验证数据源提供可插入支持。插件和 Spring Security 都不关心你从哪里获取数据，只关心你实现所需的接口以便其他类可以使用它。
您需要做的就是创建一个
UserDetailsService实现来解析 XML 并从那里创建一个GrailsUser实例。请参阅文档中的“11 Custom UserDetailsService”部分，了解示例自定义类和如何连接的描述。The Spring Security Core plugin has pluggable support for the source of user authentication data. Neither the plugin nor Spring Security care where you get the data, just that you implement the required interface so the other classes can use it.
All you'd need to do is create a
UserDetailsServiceimplementation that parses the XML and creates aGrailsUserinstance from there. See section "11 Custom UserDetailsService" in the documentation for an example customized class and description of how to wire things up.为什么要针对包含用户信息的 xml 文件进行身份验证？最简单、最快的方法是使用 grails 插件 http://www 集成 spring security .grails.org/plugin/spring-security-core。用户存储在数据库中，您可以配置很多东西，例如加密，acls，...
