Grails - 无法覆盖最终方法

我创造了RegisterController.groovy出来的spring ui package.

当我创建它时,它看起来像这样:

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

然后我只是将初始复制RegisterController.groovy到我的模板中.

package com.testApplication.register

import grails.plugin.springsecurity.SpringSecurityUtils
import grails.plugin.springsecurity.authentication.dao.NullSaltSource
import grails.plugin.springsecurity.ui.RegistrationCode
import groovy.text.SimpleTemplateEngine


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


    // override default value from base class
    static defaultAction = 'index'

    // override default value from base class
    static allowedMethods = [register: 'POST']

    def mailService
    def messageSource
    def saltSource

    def index() {
        def copy = [:] + (flash.chainedParams ?: [:])
        copy.remove 'controller'
        copy.remove 'action'
        [command: new RegisterCommand(copy)]
    }

    def register(RegisterCommand command) {

        if (command.hasErrors()) {
            render view: 'index', model: [command: command]
            return
        }

        String salt = saltSource instanceof NullSaltSource ? null : command.username
        def user = lookupUserClass().newInstance(email: command.email, username: command.username,
                accountLocked: true, enabled: true)

        RegistrationCode registrationCode = springSecurityUiService.register(user, command.password, salt)
        if (registrationCode == null || registrationCode.hasErrors()) {
            // null means problem creating the user
            flash.error = message(code: 'spring.security.ui.register.miscError')
            flash.chainedParams = params
            redirect action: 'index'
            return
        }

        String url = generateLink('verifyRegistration', [t: registrationCode.token])

        def conf = SpringSecurityUtils.securityConfig
        def body = conf.ui.register.emailBody
        if (body.contains('$')) {
            body = evaluate(body, [user: user, url: url])
        }
        mailService.sendMail {
            to command.email
            from conf.ui.register.emailFrom
            subject conf.ui.register.emailSubject
            html body.toString()
        }

        render view: 'index', model: [emailSent: true]
    }

    def verifyRegistration() {

        def conf = SpringSecurityUtils.securityConfig
        String defaultTargetUrl = conf.successHandler.defaultTargetUrl

        String token = params.t

        def registrationCode = token ? RegistrationCode.findByToken(token) : null
        if (!registrationCode) {
            flash.error = message(code: 'spring.security.ui.register.badCode')
            redirect uri: defaultTargetUrl
            return
        }

        def user

            def UserRole = lookupUserRoleClass()
            def Role = lookupRoleClass()
            for (roleName in conf.ui.register.defaultRoleNames) {
                UserRole.create user, Role.findByAuthority(roleName)
            }
            registrationCode.delete()

        def registrationCode = new RegistrationCode(username: user."$usernameFieldName")
        registrationCode.save(flush: true)

    static final passwordValidator = { String password, command ->

    }

    static boolean checkPasswordMaxLength(String password, command) {
        def conf = SpringSecurityUtils.securityConfig

        int maxLength = conf.ui.password.maxLength instanceof Number ? conf.ui.password.maxLength : 64

        password && password.length() <= maxLength
    }

    static boolean checkPasswordRegex(String password, command) {
        def conf = SpringSecurityUtils.securityConfig

        String passValidationRegex = conf.ui.password.validationRegex ?:

        if (command.password != command.password2) {
            return 'command.password2.error.mismatch'
        }
    }
}

class RegisterCommand {

    String username
    String email
    String password
    String password2

    def grailsApplication

    static constraints = {
        username blank: false, validator: { value, command ->
            if (value) {
                def User = command.grailsApplication.getDomainClass(
                    SpringSecurityUtils.securityConfig.userLookup.userDomainClassName).clazz
                if (User.findByUsername(value)) {
                    return 'registerCommand.username.unique'
                }
            }
        }
        email blank: false, email: true
        password blank: false, validator: RegisterController.passwordValidator
        password2 validator: RegisterController.password2Validator
    }
}

class ResetPasswordCommand {
    String username
    String password
    String password2

    static constraints = {
        password blank: false, validator: RegisterController.passwordValidator
        password2 validator: RegisterController.password2Validator
    }
}

但是,我收到的错误是:

class RegisterController扩展grails.plugin.springsecurity.ui.RegisterController { ` with the error:无法覆盖RegisterController的最终方法

并在

package com.testApplication.register

我尝试使用@Override,但这并没有改变它.我究竟做错了什么？

我感谢你的回答!
