在grails中从mongodb 2.4.12迁移到3.2.7的例外

Question

我将我的grails项目从2.4.4迁移到3.2.0。所以我也将我的gorm-mongodb插件迁移到6.0.0。以前版本的mongo i 2.4.12和当前版本是3.2.7。

当我将mongo版本从2.4.12迁移到3.2.7时，在我的域类中发生异常。

我有两个领域类：

class ABC implements Comparable, Serializable, Validateable { 
static mapWith = "mongo" 

ObjectId id 
String name 
String value 
App app 

static constraints = { 
    app nullable: false 
    name nullable: false 
    value nullable: false 
} 

static mapping = { 
    app reference:true 
} 

public int compareTo(Object obj) { 
    if(obj && obj instanceof ABC) { 
     if (this.name) { 
      this.name.compareTo(obj.name) 
     } else { 
      return 1 
     } 
    } else { 
     return 1 
    } 
} 
} 

和其他领域类：发生

class App implements Comparable, Serializable { 
static mapWith = "mongo" 
ObjectId id 
// Double average 
String type // design/operating 

static transients = ["name"] 

@Override 
public int compareTo(Object o) { 
    if (o && o instanceof App) { 
     return this.name?.compareTo(o.name) 
    } else { 
     return 1 
    } 
} 
}

您的应用程序的自动装配冲突。我建议完全禁用自动装配，因为它实际上对性能不利。将下面的配置，grails-app/conf/application.groovy：

grails.gorm.autowire = false 
grails.gorm.default.mapping = { 
    autowire false 
} 

无论是或删除您一定是什么地方注册的app豆。
