403在Grails 3应用程序中使用Spring Security Rest对“refresh_token”请求做出响应

我在使用Grails 3应用程序中的Spring Security Rest发出“refresh_token”请求时遇到了一些麻烦 . 我有一个带有Web前端和一些Rest endpoints 的应用程序，其他一切似乎都运行正常 . Web应用程序按预期运行，当我通过curl发出登录请求时

curl -i -X POST localhost:8080/api/login \
-H "Content-Type: application/json" \
-d '{"username":"johndoe", "password":"johndoepassword"}'

我得到了预期的响应（我已经截断了令牌）：

{
 "username":"johndoe",
 "roles":["ROLE_USER"],
 "token_type":"Bearer",
 "access_token":"eyJhbGciOiJIUzI1NiJ9.xxxxxx",
 "expires_in":3600,
 "refresh_token":"eyJhbGciOiJIUzI1NiJ9.xxxx"
}

在实际应用程序中，我可以将access_token添加到标头并在会话期间进行身份验证，没有任何问题 . 但是，当我点击“刷新令牌” endpoints 时，我得到403

curl -i -X POST localhost:8080/oauth/access_token \
-H "Content-Type: application/x-www-form-urlencoded"  \
-d "grant_type=refresh_token&refresh_token=eyJhbGciOiJIUzI1NiJ9.xxxx"

这一切在文档中看起来都非常简单，但我显然做错了什么 . 以下是我认为配置文件的相关部分：

grails.plugin.springsecurity.controllerAnnotations.staticRules = [
    [pattern: '/error',          access: ['permitAll']],
    [pattern: '/login',          access: ['permitAll']],
    [pattern: '/login/**',          access: ['permitAll']],
    [pattern: '/oauth/**',          access: ['permitAll']],
    [pattern: '/user/register',          access: ['permitAll']],
    [pattern: '/user/register/**',          access: ['permitAll']],
    [pattern: '/user/submitRegistration',          access: ['permitAll']],
    [pattern: '/logoff',          access: ['permitAll']],
    [pattern: '/shutdown',       access: ['permitAll']],
    [pattern: '/assets/**',      access: ['permitAll']],
    [pattern: '/**/js/**',       access: ['permitAll']],
    [pattern: '/**/css/**',      access: ['permitAll']],
    [pattern: '/**/images/**',   access: ['permitAll']],
    [pattern: '/**/favicon.ico', access: ['permitAll']],
    [pattern: '/surveyAdmin/**',  access: ['ROLE_ADMIN']] ,
    [pattern: '/**',               access: ['ROLE_USER']]
]

grails.plugin.springsecurity.filterChain.chainMap = [
    [pattern: '/assets/**',      filters: 'none'],
    [pattern: '/**/js/**',       filters: 'none'],
    [pattern: '/**/css/**',      filters: 'none'],
    [pattern: '/**/images/**',   filters: 'none'],
    [pattern: '/**/favicon.ico', filters: 'none'],

    [
            pattern: '/api/**',
            filters: 'JOINED_FILTERS,-anonymousAuthenticationFilter,-exceptionTranslationFilter,-authenticationProcessingFilter,-securityContextPersistenceFilter,-rememberMeAuthenticationFilter'
    ],

    [
            pattern: '/rest/**',
            filters: 'restTokenValidationFilter,restExceptionTranslationFilter,filterInvocationInterceptor'
    ],
    [pattern: '/**',             filters: 'JOINED_FILTERS']
]

谁能建议通过这里的方式？

谢谢，Alex
