Question

我在尝试将User保存到数据库时遇到异常，我正在使用： grails 2.4.0 弹簧安全核：2.0-RC3

这是我的示例代码：

class MyRegisterController {


    def creatingUser(){
        User user = new User()

        user.username = "sunny"
        user.password = "sunny123#"
        user.email = "myemail@dontexist.com"
        user.accountExpired = false
        user.save();

        println("saved...")
        render (text: "test")
    }
}

如果有人遇到类似问题，请告诉我。

好像我搞砸了grails安全核心，ui和其他插件。我创建了一个新项目，它就像一个魔术。

感谢大家的帮助。
