在简单的单向 OneToOne 映射中初始化依赖对象
我对简单的单向映射有疑问。以下是我的实体：
@Entity
public class Account extends UUIDBase {
private Profile profile;
@OneToOne(cascade = CascadeType.ALL, optional = false)
public Profile getProfile() {
return profile;
}
public void setProfile(Profile profile) {
this.profile = profile;
}
}
@Entity
public class Profile extends UUIDBase {
...
}
每个帐户都必须分配一个配置文件。该帐户应该是映射的拥有方。初始化 dependentt Profile 属性的最佳位置在哪里？我尝试在帐户实体的构造函数中初始化配置文件，但这不起作用。
I have a problem with a simple unidirectional mapping. Here are my entities:
@Entity
public class Account extends UUIDBase {
private Profile profile;
@OneToOne(cascade = CascadeType.ALL, optional = false)
public Profile getProfile() {
return profile;
}
public void setProfile(Profile profile) {
this.profile = profile;
}
}
@Entity
public class Profile extends UUIDBase {
...
}
Each account must have a Profile assigned. The account should be the owning side of the mapping. Where is the best place to initialize the dependendt Profile attribute? I tried to initialize the profile in the constructor of the Account entity but this doesn´t work.

您可以在构造函数中初始化它，但在应用程序或工厂中设置它可能会更好。
什么不起作用，你得到什么错误？
You could initialize it in the constructor, but setting it in the application or a factory may be better.
What does not work, what error do you get?
