我正在将grails项目从2.4.4迁移到3.2.0。因此，我还将gorm-mongodb插件迁移到6.0.0。 mongo的早期版本为2.4.12，当前版本为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:
Failed to convert property value of type [com.test.Application] to required type [com.test.domain.mongo.App] for property 'app'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [com.test.Application] to required type [com.test.core.domain.mongo.App] for property 'app': no matching editors or conversion strategy found

最佳答案
您的应用程序中存在 Autowiring 冲突。我建议完全禁用 Autowiring ，因为这实际上对性能不利。将以下配置放在grails-app/conf/application.groovy中:
grails.gorm.autowire = false
grails.gorm.default.mapping = {
autowire false
}
要么删除您必须在某处注册的
app bean。关于mongodb - 从Grails从MongoDB 2.4.12迁移到3.2.7的异常，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/40300205/
