运行ning 运行-app：创建名称为 'pluginManager' 的 bean 时出错

Question

当我在 STS 中运行我的 Grails 应用程序时，出现以下错误。在那之前我尝试了不同的

grails.servlet.version = "2.5"

我从 2.5 更改为 3.0，然后又从 3.0 更改回 2.5。

当我运行来自 STS 的应用程序时会发生这种情况：

只是想让你知道。我发现了问题：

我在我的域 Class 中错误地定义了属性，这导致了错误。

通过阅读错误，我没有想到我的域 Class 定义中存在错误。

那是我的域中有问题的行 Class。

static hasMany = [ attachments: long ]
