Question

我正在使用grails 2.4.2并安装了grails官方安全插件

compile ':spring-security-core:2.0-RC2'

当我第一次编译应用程序时，它出错了

然而，当我在一段时间后编译应用程序时，它编译得很好，但是当我运行App时出错了

Answer 1

最新版本的Spring Security插件spring-security-core 2.0-RC4使用Holders而不是Grails 2.4.x应用程序的折旧ApplicationHolder正常工作。

更新BuildConfig.groovy以使用最新版本：

<强> BuildConfig.groovy

...
plugins {
  ...
  compile ':spring-security-core:2.0-RC4'
  ...
}
...

Answer 2

使用Holders，您的spring-security-core版本无法正常工作更新BuildConfig.groovy以使用Spring Security Core Plugin

中的最新版本

plugins {
  ...
  compile ':spring-security-core:2.0.0'
  ...
}

使用grails安全性插件时出错
