求助各位了解RBAC的朋友。

我希望能实现一个简单的基于rbac1的java组件（含单继承，但不含权限包含互斥），对于rbac的模型已经基本熟悉了，希望各位有这方面经验的老鸟们，能提供些相关实现方面的资料。
以下是我的数据库建模。

DROP DATABASE RoleBasedAccessControl;

CREATE DATABASE RoleBasedAccessControl;

USE RoleBasedAccessControl;
/*操作表*/
CREATE TABLE operation (
	id INT PRIMARY KEY,
	/*操作的名称*/
	name VARCHAR(20) UNIQUE NOT NULL,
	/*操作的描述*/
	description VARCHAR(200)
);
/*为操作建立索引*/
CREATE UNIQUE INDEX IDX_NAME ON operation (name);

INSERT INTO operation VALUES (0, '读', null);
INSERT INTO operation VALUES (1, '写', null);
INSERT INTO operation VALUES (2, '删', null);
INSERT INTO operation VALUES (3, '改', null);

/*资源表*/
CREATE TABLE resource (
	id INT PRIMARY KEY,
	/*资源内容*/
	name VARCHAR(100) UNIQUE NOT NULL,
	/*资源的描述*/
	description VARCHAR(200)
);
/*为资源内容建立索引*/
CREATE UNIQUE INDEX IDX_RESOURCE ON resource (name);
INSERT INTO resource VALUES (0, 'index.jsp', null);
INSERT INTO resource VALUES (1, 'addOperation.jsp', null);

/*权限表*/
CREATE TABLE authorization (
	id INT PRIMARY KEY,
	/*权限的名称*/
	name VARCHAR(50) NOT NULL,
	/*权限对应的资源*/
	resource INT NOT NULL,
	/*权限使用的操作*/
	operation INT NOT NULL
);
/*为权限名称建立索引*/
CREATE UNIQUE INDEX IDX_NAME ON authorization (name);
/*为资源、操作建立索引*/
CREATE UNIQUE INDEX IDX_RESOURCE_OPERATION ON authorization (resource, operation);
/*为权限资源建立外键*/
ALTER TABLE authorization ADD CONSTRAINT FK_RESOURCE FOREIGN KEY (resource) REFERENCES resource(id);
/*为权限操作建立外键*/
ALTER TABLE authorization ADD CONSTRAINT FK_OPERATION FOREIGN KEY (operation) REFERENCES operation(id);

INSERT INTO authorization VALUES (0, 'index_r', 0, 0);
INSERT INTO authorization VALUES (1, 'index_w', 0, 1);
INSERT INTO authorization VALUES (2, 'index_d', 0, 2);
INSERT INTO authorization VALUES (3, 'index_u', 0, 3);

/*角色表*/
CREATE TABLE role (
	id INT PRIMARY KEY,
	/*父角色*/
	parent INT NOT NULL,
	/*角色名称*/
	name VARCHAR(20) UNIQUE NOT NULL,
	/*角色描述*/
	description VARCHAR(200)
);
--ALTER TABLE role ADD CONSTRAINT FK_PARENT FOREIGN KEY (parent) REFERENCES role (parent);
INSERT INTO role VALUES (0, 0, 'anonym', null);
INSERT INTO role VALUES (1, 0, 'user', null);
INSERT INTO role VALUES (2, 1, 'admin', null);
INSERT INTO role VALUES (3, 1, 'guest', null);

/*授权表*/
CREATE TABLE permission (
	/*角色*/
	role INT NOT NULL,
	/*权限*/
	authorization INT NOT NULL
);
/*为授权表建立主键*/
ALTER TABLE permission ADD CONSTRAINT PK_PERMISSION PRIMARY KEY (role, authorization);
ALTER TABLE permission ADD CONSTRAINT FK_ROLE FOREIGN KEY (role) REFERENCES role (id);
ALTER TABLE permission ADD CONSTRAINT FK_AUTHORIZATION FOREIGN KEY (authorization) REFERENCES authorization (id);

INSERT INTO permission VALUES (0, 0);
INSERT INTO permission VALUES (1, 1);
INSERT INTO permission VALUES (2, 2);
INSERT INTO permission VALUES (2, 3);
INSERT INTO permission VALUES (3, 3);
