找不到用于Spring Security的Spring Bean还记得我吗？

Question

在具有Spring Security的Grails应用中，我想在conf / spring / resource.groovy中初始化以下Spring bean：

beans = { 

    if (grailsApplication.config.grails.plugins.springsecurity.rememberMe.persistent) {
        rememberMeServices(MyPersistentTokenBasedRememberMeService) {
            userDetailsService = ref('userDetailsService')
            key = grailsApplication.config.grails.plugins.springsecurity.rememberMe.key
            cookieName = grailsApplication.config.grails.plugins.springsecurity.rememberMe.cookieName
            alwaysRemember = grailsApplication.config.grails.plugins.springsecurity.rememberMe.alwaysRemember
            tokenValiditySeconds = grailsApplication.config.grails.plugins.springsecurity.rememberMe.tokenValiditySeconds
            parameter = grailsApplication.config.grails.plugins.springsecurity.rememberMe.parameter
            useSecureCookie = grailsApplication.config.grails.plugins.springsecurity.rememberMe.useSecureCookie // false

            tokenRepository = ref('tokenRepository')
            seriesLength = grailsApplication.config.grails.plugins.springsecurity.rememberMe.persistentToken.seriesLength // 16
            tokenLength = grailsApplication.config.grails.plugins.springsecurity.rememberMe.persistentToken.tokenLength // 16
        }
    }

}

我发现这个代码在这里在页面的底部。

我收到以下错误：

为了正确初始化Bean，我必须更改什么？

无法将属性“ tokenLength”的[groovy.util.ConfigObject]类型的值转换为所需的类型[int]

这表明，我认为你没有grails.plugins.springsecurity.rememberMe.persistentToken.tokenLength属性在你的设置grailsApplication.config -当你问一个ConfigObject一个不存在的关键是什么，它返回给你的是一个新的空ConfigObject 。
