我需要關於bean屬性的hibernate映射的幫助，指的是多個類。如何在休眠狀態下動態地映射對象
在我的應用程序中，我們正在實施權限。這些權限不是特定於某個用戶的，它可能基於組（包含用戶列表）和角色。所以，權限將適用於用戶，角色和組。
以下是ddl和實體類。請檢查並幫助我。
DDL：
--stores the application users
CREATE TABLE users (
id serial PRIMARY KEY,
name text,
CONSTRAINT uk_users_name UNIQUE (name)
);
--stores the application groups
CREATE TABLE groups (
id serial PRIMARY KEY,
name text,
CONSTRAINT uk_groups_name UNIQUE (name)
);
--stores the application roles
CREATE TABLE roles (
id serial PRIMARY KEY,
name text,
CONSTRAINT uk_roles_name UNIQUE (name)
);
--stores the application object types
CREATE TABLE app_object_types (
id serial PRIMARY KEY,
name text,
CONSTRAINT uk_app_object_types_name UNIQUE (name)
);
INSERT INTO app_object_types (name) VALUES ('USERS');
INSERT INTO app_object_types (name) VALUES ('GROUPS');
INSERT INTO app_object_types (name) VALUES ('ROLES');
CREATE TABLE app_permissions (
id serial PRIMARY KEY,
object_type_id integer REFERENCES app_object_types(id), -- To represent the object type
object_id integer, -- Objecct_id refers users -> id, groups -> id, roles - id
permission_name text,
CONSTRAINT uk_permissions UNIQUE (object_type_id, object_id, permission_name)
);
實體類：
@Entity
@Table(name = "users")
public class Users {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private int name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getName() {
return name;
}
public void setName(int name) {
this.name = name;
}
}
@Entity
@Table(name = "groups")
public class Groups {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private int name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getName() {
return name;
}
public void setName(int name) {
this.name = name;
}
}
@Entity
@Table(name = "roles")
public class Roles {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private int name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getName() {
return name;
}
public void setName(int name) {
this.name = name;
}
}
@Entity
@Table(name = "app_object_types")
public class AppObjectTypes {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private int name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getName() {
return name;
}
public void setName(int name) {
this.name = name;
}
}
@Entity
@Table(name = "app_permissions")
public class AppPermissions {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
@ManyToOne
private String permissionName;
@ManyToOne
private AppObjectTypes appObjectTypes;
private int objectId;
private Class<?> dependentObject;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getPermissionName() {
return permissionName;
}
public void setPermissionName(String permissionName) {
this.permissionName = permissionName;
}
public AppObjectTypes getAppObjectTypes() {
return appObjectTypes;
}
public void setAppObjectTypes(AppObjectTypes appObjectTypes) {
this.appObjectTypes = appObjectTypes;
}
public int getObjectId() {
return objectId;
}
public void setObjectId(int objectId) {
this.objectId = objectId;
}
public Class<?> getDependentObject() {
return dependentObject;
}
public void setDependentObject(Class<?> dependentObject) {
this.dependentObject = dependentObject;
}
}
我要地圖的用戶（或）組（或）作用的bean對象AppPermissions - 使用Hibernate> dependentObject。我不知道這是否可能，請幫助我。
