在grails中從mongodb 2.4.12遷移到3.2.7的例外

Question

我將我的grails項目從2.4.4遷移到3.2.0。所以我也將我的gorm-mongodb插件遷移到6.0.0。以前版本的mongo i 2.4.12和當前版本是3.2.7。

當我將mongo版本從2.4.12遷移到3.2.7時，在我的域類中發生異常。

我有兩個領域類：

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 
    } 
} 
} 

和其他領域類：發生

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 
    } 
} 
}

Answer 1

您的應用程序的自動裝配衝突。我建議完全禁用自動裝配，因爲它實際上對性能不利。將下面的配置，grails-app/conf/application.groovy：

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

無論是或刪除您一定是什麼地方註冊的app豆。
