我正在将我的 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。以前的 mongo 版本是 2.4.12，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，我的域类中发生了异常。

我有两个域类：

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
    }
}
}

和另一个域类：

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
    }
}
}

发生异常：

您的应用程序中存在自动装配冲突。我建议完全禁用自动装配，因为它实际上对性能不利。将以下配置放入grails-app/conf/application.groovy：

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

要么删除，要么删除app您必须在某处注册的 bean。
