使用 grails 安全插件时出错

Question

我正在使用 grails 2.4.2 并且已经安装了 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，它给出了一个错误

但是当我稍后编译该应用程序时，它编译得很好，但是当我运行该应用程序时出现错误

Answer 1

最新版本的 Spring Security 插件 spring-security-core 2.0-RC4 可以在 Grails 2.4.x 应用程序中使用 Holders 而不是已弃用的 ApplicationHolder 正常工作。

更新您的 BuildConfig.groovy 以使用最新版本：

BuildConfig.groovy

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

Answer 2

您的 spring-security-core 版本在使用 Holders 时无法正常工作， 更新您的 BuildConfig.groovy 以使用来自Spring Security Core Plugin 的最新版本

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