Grails3:AuthRoleControl中java.lang.Boolean hasErrors（）的返回类型与grails.artefact.Controller中的Boolean不兼容

我已经将我的应用程序从Grails2.5升级到Grails3.3.11。我已经完成了所有步骤，一切看起来都很好，但当我运行应用程序时。我有一个错误：

启动失败： /home/server dev/Documents/dev_repo/tms/grails app/controllers/org/niport/auth/AuthRoleController.groovy:-1:org.niport.auth.AuthRoleController中java.lang.Boolean hasrerrors（）的返回类型与grails.artifact.Controller中的Boolean不兼容 . 在[-1:-1]@第1行第1列。 1错误

失败：生成失败，出现异常

• 出了什么问题： 任务“：compileGroovy”的执行失败

编译失败；有关详细信息，请参阅编译器错误输出

任何想法或帮助都会很有帮助，非常感谢

类AuthRoleControl实现可验证的

没有充分的理由让控制器实现

可验证的

特性，这样做会导致问题

---

问题是您将获得两个名为

hasrerrors

，一个来自，一个来自，并且它们具有不同的返回类型。

org.niport.auth.authroleconroller中是否有名为

hasrerrors

的方法？如果否，控制器是否显式扩展任何类或实现任何特征？Hi@JeffScottBrown这只是与控制器关联的Spring错误交互的实例。但我可以将相关控制器的代码作为答案共享这与您的问题无关，但您添加的代码指向了另一个问题，即您的控制器将无法与并发请求兼容，因为您在

AuthRoleControl

中处理

currentUser

。除非将控制器配置为请求范围，否则这将被破坏，这是一个坏主意。从控制器中删除

可验证的

不会消耗任何功能。它的出现并没有带来任何帮助。谢谢Jeff，我将删除可验证的界面，如果它有效，我现在就让你使用
