Grails 内联插件和 Spring Security

Question

我通过使用插件将我的 grails 应用程序分解为模块，然后将内联插件位置添加到 BuildConfig.groovy。现在我有一个名为“admin”的 grails 应用程序和一个名为“common”的插件。

'common' 插件包含我所有的共享域对象，并且还安装了 spring-security-core 插件。据我了解，我还需要将 spring-security-core 插件安装到“admin”中，所以我已经这样做了。

我在“common”上运行了 s2-quickstart，它包含 Config.groovy 中用户和角色的域映射。当我运行应用程序时，它会在受保护的内容上适当地重定向（通过 @Secured 注释）。但是，当我尝试进行身份验证时，它仍在尝试查询 Person 而不是 User。

我将“common”Config.groovy 中的域映射添加到“admin”中，查询现在可以工作，但它找不到我添加到“common”插件中存在的用户域的其他属性.

我在这里遗漏了什么吗？我宁愿不必将用户和角色放在“管理员”应用程序中，因为我希望能够在另一个也使用“通用”插件的应用程序中重用用户和角色。

更新：我意识到我安装了冲突的 spring-security-core 插件（复制和粘贴问题）。我解决了它试图找到Person而不是User的问题。但是，现在我得到了以下堆栈跟踪

Answer 1

所以听从 Burt 的建议，我在 CommonGrailsPlugin.groovy 中添加了以下内容..

def doWithApplicationContext = { applicationContext ->
    SpringSecurityUtils.securityConfig.userLookup.userDomainClassName = 'com.wbr.common.security.User'
    SpringSecurityUtils.securityConfig.userLookup.authorityJoinClassName = 'com.wbr.common.security.UserRole'
    SpringSecurityUtils.securityConfig.authority.className = 'com.wbr.common.security.Role'
}

这使我不必将此配置复制到依赖此插件的所有应用程序中。而且由于这些应用程序不需要自定义此配置，因此效果很好！谢谢伯特！

Answer 2

只需确保以下几行与conf/Config.groovy 中的包和域对象名称相匹配。相应地更改包和对象名称

// Added by the Spring Security Core plugin:
grails.plugins.springsecurity.userLookup.userDomainClassName = 'THIS.IS.THE PACKAGE.Person'
grails.plugins.springsecurity.userLookup.authorityJoinClassName = 'THIS.IS.THE.PACKAGE.PersonAuthority'
grails.plugins.springsecurity.authority.className = 'THIS.IS.THE.PACKAGE.Authority'

Answer 3

这就是正在发生的事情。 为了灵活性，安全插件允许您在 conf/Config.gs 中定义用于安全的类。然后它通过执行动态加载该类

def User = AH.application.getDomainClass( SpringSecurityUtils.securityConfig.userLookup.userDomainClassName).clazz )

并使用 User 类。如果您更改了类名并且没有更改配置，您将收到此错误。
