功能NHibernate：映射列表

Question

的字典我有一個分貝以下表格：

• 角色：[ID，姓名，...]
• 權限：[ID，姓名，... ]
• MetaDataDefinitions：[ID，姓名，...]
• RolePermissions：[ID，角色ID，PermissionId，MetaDataDefinitionId]

POCO類：

class Role { 
public Role() { 
    MetaDataPermissions = new Dictionary<MetaDataDefinition, Permission>() ; 
} 

public virtual int Id { get; set; } 
public virtual string Name { get; set; } 

public virtual IDictionary<MetaDataDefinition, Permission> MetaDataPermissions { get; set; } 
} 


class Permission { 
public Permission() { 
    MetaDataRoles = new Dictionary<MetaDataDefinition, Role>() ; 
} 

public virtual int Id { get; set; } 
public virtual string Name { get; set; } 

public virtual IDictionary<Role, MetaData> RolesMetaData { get; set; } 
} 

class MetaData { 
public MetaData() { 
    RolePermissions = new Dictionary<Role, Permission>() ; 
} 

public virtual int Id { get; set; } 
public virtual string Name { get; set; } 

public virtual IDictionary<Role, Permission> RolePermissions { get; set; } 
} 

流利的映射：

class RoleMap : ClassMap<Role> { 
public RoleMap() { 
    [...] 
    HasManyToMany(x => x.MetaDataPermissions) 
     .Table("RolePermissions") 
     .AsEntityMap("MetaDataDefinitionId", "PermissionId") 
     .KeyColumn("RoleId") ; 
    [...] 
} 
} 

class PermissionMap : ClassMap<Permission> { 
public PermissionMap() { 
    [...] 
    HasManyToMany(x => x.RolesMetaData) 
     .Table("RolePermissions") 
     .AsEntityMap("RoleId", "MetaDataDefinitionId") 
     .KeyColumn("PermissionId") ; 
    [...] 
} 
} 

class MetaDataMap : ClassMap<MetaData> { 
public MetaDataMap() { 
    [...] 
    HasManyToMany(x => x.RolePermissions) 
     .Table("RolePermissions") 
     .AsEntityMap("RoleId", "PermissionId") 
     .KeyColumn("MetaDataDefinitionId") ; 
    [...] 
} 
} 

但在POCO類，我需要這樣的：

public virtual IDictionary<Role, IList<MetaData>> RolesMetaData { get; set; } 

怎麼這麼字典應該在映射表示？

不支持直接映射列表字典。
