Hibernate注释映射，复杂图

Question

我为交付图表制作正确的映射存在一些大问题。它看起来像这样：

现在，到目前为止，我做到了这一点，希望它确定（ommited getters / setters）。您会注意到USERS有DOMAIN_ID，请忽略它，因为它不是完整的图表。

FunctionalityGroup

@Entity
@Table(name = "FUNCTIONALITY_GROUP")
public class FunctionalityGroup implements Serializable
{
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "FUNCTIONALITY_GROUP_ID")
private Long functionalityGroupId;

@Column(name = "FUNCTIONALITY_GROUP_NM")
private String functionalityGroupName;

@Column(name = "FUNCTIONALITY_GROUP_DESC")
private String functionalityGroupDesc;

@OneToMany(fetch = FetchType.LAZY, mappedBy = "funcionalityGroupId")
private List<Functionality> functionalityList;
}

功能

@Entity
@Table(name = "FUNCTIONALITY")
public class Functionality implements Serializable
{
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "FUNCTIONALITY_ID")
private Long functionalityId;

@Column(name = "FUNCTIONALITY_NM")
private String functionalityGroupName;

@Column(name = "FUNCTIONALITY_DESC")
private String functionalityGroupDesc;

@Column(name = "FUNCTIONALITY_GROUP_ID")
private Long funcionalityGroupId;

@ManyToMany(fetch = FetchType.LAZY)
@JoinTable(name = "ROLE_FUNCTIONALITY",
        joinColumns = {@JoinColumn(name = "FUNCTIONALITY_ID")},
        inverseJoinColumns = {@JoinColumn(name = "ROLE_ID")})
private List<Role> roleList;
}

角色

@Entity
@Table(name = "ROLE")
public class Role implements Serializable
{
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "ROLE_ID")
private Integer roleId;
@Column(name = "ROLE_NM")
private String roleName;
@Column(name = "ROLE_DESC")
private String roleDesc;
@Column(name = "OBJECT_TYPE")
private String objectType;

@ManyToMany(fetch = FetchType.LAZY, mappedBy = "roleList")
private List<Functionality> functionalityListy;
}

用户

@Entity
@Table(name = "USERS")
public class Users implements Serializable
{
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "USER_ID")
private Long userId;
@Column(name = "USER_DESC")
private String userDesc;
@Column(name = "FIRST_NM")
private String firstNM;
@Column(name = "LAST_NM")
private String lastNM;
@Column(name = "IS_ENABLED")
private String isEnabled;
}

我不知道如何使用对象世界映射和处理Role_Member和Role_Member_Entry，有人可以给我一些点击吗？谢谢！

通常我会将具有多个角色的用户连接到多个，但实体Role_Member_Entry会破坏所有内容。
