我已经从RegisterController.groovy创建了spring ui package。
当我创建它时，它看起来像那样：
class RegisterController extends grails.plugin.springsecurity.ui.RegisterController{
}
然后我将初始的RegisterController.groovy复制到我的模板中。
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
// TODO to ui service
RegistrationCode.withTransaction { status ->
String usernameFieldName = SpringSecurityUtils.securityConfig.userLookup.usernamePropertyName
user = lookupUserClass().findWhere((usernameFieldName): registrationCode.username)
if (!user) {
return
}
user.accountLocked = false
user.save(flush:true)
def UserRole = lookupUserRoleClass()
def Role = lookupRoleClass()
for (roleName in conf.ui.register.defaultRoleNames) {
UserRole.create user, Role.findByAuthority(roleName)
}
registrationCode.delete()
}
if (!user) {
flash.error = message(code: 'spring.security.ui.register.badCode')
redirect uri: defaultTargetUrl
return
}
springSecurityService.reauthenticate user.username
flash.message = message(code: 'spring.security.ui.register.complete')
redirect uri: conf.ui.register.postRegisterUrl ?: defaultTargetUrl
}
def forgotPassword() {
if (!request.post) {
// show the form
return
}
String username = params.username
if (!username) {
flash.error = message(code: 'spring.security.ui.forgotPassword.username.missing')
redirect action: 'forgotPassword'
return
}
String usernameFieldName = SpringSecurityUtils.securityConfig.userLookup.usernamePropertyName
def user = lookupUserClass().findWhere((usernameFieldName): username)
if (!user) {
flash.error = message(code: 'spring.security.ui.forgotPassword.user.notFound')
redirect action: 'forgotPassword'
return
}
def registrationCode = new RegistrationCode(username: user."$usernameFieldName")
registrationCode.save(flush: true)
String url = generateLink('resetPassword', [t: registrationCode.token])
def conf = SpringSecurityUtils.securityConfig
def body = conf.ui.forgotPassword.emailBody
if (body.contains('$')) {
body = evaluate(body, [user: user, url: url])
}
mailService.sendMail {
to user.email
from conf.ui.forgotPassword.emailFrom
subject conf.ui.forgotPassword.emailSubject
html body.toString()
}
[emailSent: true]
}
def resetPassword(ResetPasswordCommand command) {
String token = params.t
def registrationCode = token ? RegistrationCode.findByToken(token) : null
if (!registrationCode) {
flash.error = message(code: 'spring.security.ui.resetPassword.badCode')
redirect uri: SpringSecurityUtils.securityConfig.successHandler.defaultTargetUrl
return
}
if (!request.post) {
return [token: token, command: new ResetPasswordCommand()]
}
command.username = registrationCode.username
command.validate()
if (command.hasErrors()) {
return [token: token, command: command]
}
String salt = saltSource instanceof NullSaltSource ? null : registrationCode.username
RegistrationCode.withTransaction { status ->
String usernameFieldName = SpringSecurityUtils.securityConfig.userLookup.usernamePropertyName
def user = lookupUserClass().findWhere((usernameFieldName): registrationCode.username)
user.password = springSecurityUiService.encodePassword(command.password, salt)
user.save()
registrationCode.delete()
}
springSecurityService.reauthenticate registrationCode.username
flash.message = message(code: 'spring.security.ui.resetPassword.success')
def conf = SpringSecurityUtils.securityConfig
String postResetUrl = conf.ui.register.postResetUrl ?: conf.successHandler.defaultTargetUrl
redirect uri: postResetUrl
}
protected String generateLink(String action, linkParams) {
createLink(base: "$request.scheme://$request.serverName:$request.serverPort$request.contextPath",
controller: 'register', action: action,
params: linkParams)
}
protected String evaluate(s, binding) {
new SimpleTemplateEngine().createTemplate(s).make(binding)
}
static final passwordValidator = { String password, command ->
if (command.username && command.username.equals(password)) {
return 'command.password.error.username'
}
if (!checkPasswordMinLength(password, command) ||
!checkPasswordMaxLength(password, command) ||
!checkPasswordRegex(password, command)) {
return 'command.password.error.strength'
}
}
static boolean checkPasswordMinLength(String password, command) {
def conf = SpringSecurityUtils.securityConfig
int minLength = conf.ui.password.minLength instanceof Number ? conf.ui.password.minLength : 8
password && password.length() >= minLength
}
static boolean checkPasswordMaxLength(String password, command) {
def conf = SpringSecurityUtils.securityConfig
int maxLength = conf.ui.password.maxLength instanceof Number ? conf.ui.password.maxLength : 64
password && password.length() <= maxLength
}
static boolean checkPasswordRegex(String password, command) {
def conf = SpringSecurityUtils.securityConfig
String passValidationRegex = conf.ui.password.validationRegex ?:
'^.*(?=.*\\d)(?=.*[a-zA-Z])(?=.*[!@#$%^&]).*$'
password && password.matches(passValidationRegex)
}
static final password2Validator = { value, command ->
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，我收到错误：
class RegisterController extends grails.plugin.springsecurity.ui.RegisterController {` with the error:无法覆盖RegisterController的最终方法。
和
package com.testApplication.register

我尝试使用@Override但是，这并没有改变它。我究竟做错了什么？
感谢您的回答！

如果应用于类，则final关键字会阻止您修改类，或者如果应用于方法，则会阻止您修改方法。
来自http://en.wikipedia.org/wiki/Final_%28Java%29：
子类不能覆盖或隐藏最终方法。这用于防止子类的意外行为改变可能对类的功能或一致性至关重要的方法。
如果使用final方法对类进行子类化，则需要单独保留该方法。如果该类是final，则根本不能将其子类化。

刷新依赖项解决了我的问题。
