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);
