【中文标题】一个组件需要一个名为 \'\' 的 bean，但无法找到【英文标题】：A component required a bean named '' that could not be found一个组件需要一个名为 '' 的 bean，但无法找到 【发布时间】：2017-10-05 21:33:12 【问题描述】：我正在尝试按照this post 的说明使用 grails-spring-security-rest 插件构建我的第一个 grails 应用程序。
但是，当我尝试运行应用程序时，它会给出以下输出：

更新 1
我在 logback.groovy
中添加了以下行logger("org.springframework.security", DEBUG, ['STDOUT'], false)
logger("grails.plugin.springsecurity", DEBUG, ['STDOUT'], false)
logger("org.pac4j", DEBUG, ['STDOUT'], false)
然而，控制台输出和 stacktrace.log 文件的输出与上面发布的相同
非常感谢有关如何解决此错误的任何建议。
【问题讨论】：
Spring 库通常非常适合为您提供信息丰富的堆栈跟踪。这似乎不是这里的情况。也许您可以降低日志记录级别以获得更好的信息？ 【参考方案1】：最后，我能够解决问题：
问题 1： 我手动创建了 User Role 和 UserRole 类，而不是使用
grails s2-quickstart com.app-name User Role
如here所述
问题 2： 我对 chainMap 过滤器使用了错误的格式。这是对我有用的那个
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,-exceptionTranslationFilter,-authenticationProcessingFilter,-securityContextPersistenceFilter'], // Stateless chain
[pattern: '/data/**', filters: 'JOINED_FILTERS,-exceptionTranslationFilter,-authenticationProcessingFilter,-securityContextPersistenceFilter'], // Stateless chain
[pattern: '/**', filters: 'JOINED_FILTERS,-restTokenValidationFilter,-restExceptionTranslationFilter'] // Traditional chain
]
【讨论】：
【参考方案2】：com.form.application.UserPasswordEncoderListener 中的字段 springSecurityService 需要找不到类型为“grails.plugin.springsecurity.SpringSecurityService”的 bean。
行动：
考虑在你的配置中定义一个“grails.plugin.springsecurity.SpringSecurityService”类型的bean 还是遇到这个问题
【讨论】：
以上是关于一个组件需要一个名为 '' 的 bean，但无法找到的主要内容，如果未能解决你的问题，请参考以下文章
字段存储库需要一个名为“entityManagerFactory”的 bean，但无法找到
