java.lang.IllegalStateException：上类的方法[域类]的Grails应用程序之外使用

context.GrailsContextLoaderListener错误初始化应用：采用上类的方法[域类（auth.Role）] 外的Grails应用程序。如果在测试的环境中正确使用模拟API或引导Grails运行。java.lang.IllegalStateException：上类的方法[域类]的Grails应用程序之外使用

java.lang.IllegalStateException：类[Domain Class（auth.Role）]上的方法在Grails应用程序之外使用。如果在正确使用模拟API或引导Grails 的测试环境中运行。

此异常是在该行抛出：

def existingRole = Role.findByAuthority(role) // Code Interrupts

Role.groovy

import org.bson.types.ObjectId 

class Role { 

    // static mapWith = 'mongo' (For mongoDb we have plugin, so this is working) 
    static mapWith = 'none' //(Migrating MongoDB to postgreSql so changed mapWith to 'none') 
    ObjectId id 
    String authority 

    static constraints = { 
     authority blank: false, unique: true 
    } 
}
