grails - 在Grails GSP中从用户类springSecurityService读取未生成的属性

Question

我正在Grails中编写一个更新的用户数据表单。在更新之前，它必须在字段中显示旧的用户数据。这是此表单的一部分:

<g:form class="form-signin" controller="VisitorSpace">
    <label for="login" class="sr-only">Login</label>
    <g:textField id="login" class="form-control" name="login" placeholder="Login"
        value="${applicationContext.springSecurityService.principal.username}" required="" autofocus=""/>
    <label for="firstName" class="sr-only">Your name</label>
    <g:textField id="firstName" class="form-control" name="firstName" placeholder="Your name"
        value="${applicationContext.springSecurityService.principal.firstName}" required="" type="text"/>
...
</g:form>

这是我的域User-class的一部分:

class Person {

    transient springSecurityService

    String username
    String password
    boolean enabled = true
    boolean accountExpired
    boolean accountLocked
    boolean passwordExpired

    String firstName
    String lastName
    String email
    boolean isAdminCafee = false
    static transients = ['springSecurityService']

    static constraints = {
        username blank: false, unique: true
        firstName blank: false
        lastName blank: false
        password blank: false
        email blank: false, unique: true
    }
    ...
}

域类的生成的用户名属性正确获取，但是当我尝试请求未生成的firstName属性时，出现错误:

URI:/restorator/visitorSpace/editPrivateDataClass:groovy.lang.MissingPropertyExceptionMessage:
No such property: firstName for class: grails.plugin.springsecurity.userdetails.GrailsUser

解决了。我已经通过使用参数渲染gsp解决了这个问题。
gsp-controller的渲染 Action :

def editPrivateData(){
        def user = springSecurityService.currentUser
        render (view:'editPrivateData.gsp', model: [user: user])
    }

以gsp形式使用:

<g:textField id="firstName" class="form-control" name="firstName" placeholder="Your name" var = "user" value="${user.firstName}" required="" type="text"/>
