Grails Spring Security UI註冊其他字段

我想在插件提供的用戶註冊字段中添加其他字段。我相信重寫RegisterController是添加更多字段的正確方法（糾正我，如果我錯了）。我從原始文件創建了一個新的RegisterController.groovy，其中包含以下內容。此時我沒有添加新的字段屬性，只是試圖模仿插件的功能。Grails Spring Security UI註冊其他字段

package myPackage 

import grails.plugin.springsecurity.authentication.dao.NullSaltSource 
import grails.plugin.springsecurity.ui.CommandObject 
import grails.plugin.springsecurity.ui.RegistrationCode 
import grails.plugin.springsecurity.ui.strategy.MailStrategy 
import grails.plugin.springsecurity.ui.strategy.PropertiesStrategy 
import grails.plugin.springsecurity.ui.strategy.RegistrationCodeStrategy 

class RegisterController extends grails.plugin.springsecurity.ui.RegisterController { 

    static defaultAction = 'register' 

    def saltSource 
    MailStrategy uiMailStrategy 
    RegistrationCodeStrategy uiRegistrationCodeStrategy 
    PropertiesStrategy uiPropertiesStrategy 

    def register(RegisterCommand registerCommand) { 

     if (!request.post) { 
      return [registerCommand: new RegisterCommand()] 
     } 

     if (registerCommand.hasErrors()) { 
      return [registerCommand: registerCommand] 
     } 

     def user = uiRegistrationCodeStrategy.createUser(registerCommand) 
     String salt = saltSource instanceof NullSaltSource ? null : registerCommand.username 
     RegistrationCode registrationCode = uiRegistrationCodeStrategy.register(user, registerCommand.password, salt) 

     if (registrationCode == null || registrationCode.hasErrors()) { 
      // null means problem creating the user 
      flash.error = message(code: 'spring.security.ui.register.miscError') 
      return [registerCommand: registerCommand] 
     } 

     sendVerifyRegistrationMail registrationCode, user, registerCommand.email 

     [emailSent: true, registerCommand: registerCommand] 
    } 

} 

class RegisterCommand implements CommandObject { 

    protected static Class<?> User 
    protected static String usernamePropertyName 

    String username 
    String email 
    String password 
    String password2 

    static constraints = { 
     username validator: { value, command -> 
      if (!value) { 
       return 
      } 

      if (User.findWhere((usernamePropertyName): value)) { 
       return 'registerCommand.username.unique' 
      } 
     } 
     email email: true 
     password validator: RegisterController.passwordValidator 
     password2 nullable: true, validator: RegisterController.password2Validator 
    } 
}

當我運行這個程序，我得到一個錯誤

Cannot invoke method findWhere() on null object.

任何想法來解決這個問題，將不勝感激。

你是否希望這個額外的字段在數據庫中持久化在用戶域類？ –

是的，那是目標。我還需要弄清楚如何使註冊頁面遵守用戶域類的約束。 – elixir

的grails.plugin.springsecurity.ui.RegisterController具有此包私有方法：

void afterPropertiesSet() { 
    super.afterPropertiesSet() 

    RegisterCommand.User = User 
    RegisterCommand.usernamePropertyName = usernamePropertyName 

    forgotPasswordEmailBody = conf.ui.forgotPassword.emailBody ?: '' 
    registerEmailBody = conf.ui.register.emailBody ?: '' 
    registerEmailFrom = conf.ui.register.emailFrom ?: '' 
    registerEmailSubject = conf.ui.register.emailSubject ?: '' 
    registerPostRegisterUrl = conf.ui.register.postRegisterUrl ?: '' 
    registerPostResetUrl = conf.ui.register.postResetUrl ?: '' 
    successHandlerDefaultTargetUrl = conf.successHandler.defaultTargetUrl ?: '/' 

    passwordMaxLength = conf.ui.password.maxLength instanceof Number ? conf.ui.password.maxLength : 64 
    passwordMinLength = conf.ui.password.minLength instanceof Number ? conf.ui.password.minLength : 8 
    passwordValidationRegex = conf.ui.password.validationRegex ?: '^.*(?=.*\\d)(?=.*[a-zA-Z])(?=.*[[email protected]#$%^&]).*$' 
}

其中RegisterCommand.User值被設置。在新的RegistrationController中也這樣做。
