Question

I got the above error though i have set the ID manually, Im not using auto generated key here. when i set the key and pass the object to

entityManager.persist(obj);

it gives the above error. any help... plz

thanks

这是安装Info级,在安装Info物体时,我发现上述错误。完全错误是

org.hibernate.id.IdentifierGenerationException: ids for this class must be manually assigned before calling save(): se.cambio.cimonitor.jpa.table.ModuleInfo

因此,我附上了模块Info课程。

package se.cambio.cimonitor.jpa.table;

Answer 1

您在模块Infos收集上都有一栏,因此,如果你节省安装信息,就会设法拯救所有相关模块Infos。你们需要确保,在保留安装Info物体之前,安装单元信息器。

@OneToMany(fetch = FetchType.EAGER, mappedBy = "installationInfo", 
   targetEntity=ModuleInfo.class, cascade={CascadeType.ALL})    //targerEntity is added by Isuru
public Set<ModuleInfo> getModuleInfos() {
    return this.moduleInfos;
}
