Jhipster：如何使用字段而不是ID创建关系

Question

I have 2 entities Country abd competions and i want to build a relationship betwenn them using the isoCode of the country, but when i generate the database(mySql) i find that the relation is based on the generated country_id. What i'm missing? Can i specify my own id and remove the generated id from the jdl file?

entity Country {
    isoCode String required
    .
    .
}

entity Competition {
    priority Integer,
    code String,
    name String
}

relationship OneToMany {
    Country to Competition{country(isoCode)}, 

   }

Thanks

JHipster仅支持关系的技术ID，如果要使用业务ID，则必须手动对其进行编码，也许可以看看Hibernate @NaturalId
