我没有找到一个实际的问题,但无论如何我都会回答。:)
person_skills 表不需要代理键。由 person_id 和 Skill_type_id 组成的复合键应该足够了。我相信以下类和映射反映了您在这里要完成的工作。
课程:
public class Person
{
public virtual int PersonId { get; set; }
public virtual String Name { get; set; }
public virtual IList<PersonSkills> Skills { get; set; }
}
public class SkillType
{
public virtual int SkillTypeId { get; set; }
public virtual String SkillName { get; set; }
public virtual IList<PersonSkills> Persons { get; set; }
}
public class PersonSkills
{
public virtual int PersonId { get; set; }
public virtual int SkillTypeId { get; set; }
public virtual int BaseScore { get; set; }
public virtual int MiscScore { get; set; }
public override bool Equals(object obj)
{
if (ReferenceEquals(this, obj))
{
return true;
}
if (obj == null || !(obj is PersonSkills))
{
return false;
}
PersonSkills o = obj as PersonSkills;
return (this.PersonId == o.PersonId
&& this.SkillTypeId == o.SkillTypeId);
}
public override int GetHashCode()
{
int hash = 13;
hash = hash + this.PersonId.GetHashCode();
hash = hash + this.SkillTypeId.GetHashCode();
return hash;
}
}
映射:(FluentNhibernate)
public class PersonMap : ClassMap<Person>
{
public PersonMap()
{
Id(x => x.PersonId);
Map(x => x.Name);
HasMany(x => x.Skills)
.KeyColumn("PersonId")
.Cascade.All();
}
}
public class SkillTypeMap : ClassMap<SkillType>
{
public SkillTypeMap()
{
Id(x => x.SkillTypeId);
Map(x => x.SkillName);
HasMany(x => x.Persons)
.KeyColumn("SkillTypeId")
.Cascade.All();
}
}
public class PersonSkillsMap : ClassMap<PersonSkills>
{
public PersonSkillsMap()
{
CompositeId()
.KeyProperty(x => x.PersonId)
.KeyProperty(x => x.SkillTypeId);
Map(x => x.BaseScore);
Map(x => x.MiscScore);
}
}
映射(hbm,由 FluentNHibernate 生成 - 我删除了不需要的输出):
