这是我的具有Spring Security的用户类

   } 
 
   protected void encodePassword() { 
      password = springSecurityService.encodePassword(password)

   String toString(){ 
      return "SecUser $username" 
   } 
} 

No such property: firstName for class: org.codehaus.groovy.grails.plugins.springsecurity.GrailsUser

请您参考如下方法:

loggedInUserInfo仅可以访问“principal”中的数据，“principal”通常是GrailsUser的实例。数据包括用户名，ID，分配的角色名称，以及有关是否启用用户，锁定帐户等的一些 bool(boolean) 值。很容易将GrailsUser子类化并创建自己的UserDetailsService并在此期间从用户域类捕获其他数据身份验证，并将其存储在GrailsUser子类中以使其可用于此标签；有关更多信息，请参见http://grails-plugins.github.io/grails-spring-security-core/docs/manual.1273/guide/11%20Custom%20UserDetailsService.html。

如果数据是只读的，这将很好地工作，因为它将被缓存直到用户注销或 session 到期为止。如果要显示的数据可以更改，请检索用户实例并将其添加到从 Controller 操作返回的模型图中:

class MyController { 
 
   def springSecurityService 
 
   def theAction() { 
       ... 
       def user = springSecurityService.currentUser 
       [user: user, foo: 5, bar: "whatever", ...] 
   } 
}
