Grails，Spring Security Rest Plugin，无法在空对象上调用方法 loadUserByToken()

Question

我正在尝试在 grails 框架(2.5.0)中使用 Spring Security Plugin(2.0.0)和 Spring Authentication Rest Plugin(1.5.3)实现基于 token 的身份验证。我将 header 字段“x-auth-token”设置为 token 并发布到目标 Controller URL。但是，IDE(Intellij IDEA)弹出此错误消息

我检查了这个 loadUserByToken() 方法，它是在 tokenStorageService 上调用的。我不知道为什么这个 tokenStorageService 是空对象。 Spring Security 和 Spring Security Plugin 配置如下:

        }
    }
}

资源.groovy

import grails.plugin.springsecurity.rest.RestAuthenticationProvider
beans = {
    restAuthenticationProvider(RestAuthenticationProvider);
}

我检查了数据库， token 存储在 authentication_token 表中。我是 grails 的新手，一直在搜索几个小时，一点头绪都没有。谁能帮我？非常感激。

如果您还需要什么，请告诉我。

对于有同样问题的人，经过多次尝试，我终于想通了。看来我不应该在resources.groovy 中声明restAuthenticationProvider，也不应该在config.groovy 中将restAuthenticationProvider 添加到grails.plugin.springsecurity.providerNames。 spring-security-core 和 spring-security-rest 的完整配置如下:

配置.groovy

grails {
    plugin {
        springsecurity {

            useSecurityEventListener = true

            filterChain {
                chainMap = [
                        '/api/**': 'JOINED_FILTERS,-exceptionTranslationFilter,-authenticationProcessingFilter,-securityContextPersistenceFilter,-rememberMeAuthenticationFilter',  // Stateless chain
                        '/**': 'JOINED_FILTERS,-restTokenValidationFilter,-restExceptionTranslationFilter'                                                                          // Traditional chain
                ]
            } //filterChain

            apf {
                filterProcessesUrl = '/api/login'
            } //apf

            rest {

                login {
                    active = true
                    useRequestParamsCredentials = false
                    useJsonCredentials = true
                    usernamePropertyName = 'j_username'
                    passwordPropertyName = 'j_password'
                    endpointUrl = '/api/login'
                } //login

                logout {

                } //logout

                token {

                    validation {
                        active = true
                        endpointUrl = '/api/validate'
                        useBearerToken = false
                        headername = 'X-Auth-Token'
                    } //validation

                    generation {
//                        active = true
//                        useSecureRandom = true;
//                        useUUID = false;
                    }

                    rendering {
                        usernamePropertyName = 'username'
                        authoritiesPropertyName = 'roles'
                        tokenPropertyName = 'token'
                    }

                    storage {
//                        useJWT = true;
                    } //storage
                } //token
            } //rest

            cors.headers = ['Access-Control-Allow-Headers': 'Content-Type, Authorization, X-Auth-Token']
        } //springsecurity
    } //plugin
} //grails

您应该使用字段“j_username”和“j_password”以 json 格式发送用户名和密码，它将返回 json 格式的 token 。然后，在“X-Auth-Token” header 字段中将请求连同此 token 一起发送到您要查询的api。
