SpringBoot整合Shiro的代码详解

shiro是一个权限框架,具体的使用可以查看其官网 http://shiro.apache.org/  它提供了很方便的权限认证和登录的功能.

　　而springboot作为一个开源框架,必然提供了和shiro整合的功能!接下来就用springboot结合springmvc,mybatis,整合shiro完成对于用户登录的判定和权限的验证.

　　1.准备数据库表结构

　　这里主要涉及到五张表:用户表,角色表(用户所拥有的角色),权限表(角色所涉及到的权限),用户-角色表(用户和角色是多对多的),角色-权限表(角色和权限是多对多的).表结构建立的sql语句如下:

CREATE TABLE `module` (
 `mid` int(11) NOT NULL AUTO_INCREMENT,`mname` varchar(255) DEFAULT NULL,PRIMARY KEY (`mid`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of module
-- ----------------------------
INSERT INTO `module` VALUES ('1','add');
INSERT INTO `module` VALUES ('2','delete');
INSERT INTO `module` VALUES ('3','query');
INSERT INTO `module` VALUES ('4','update');
-- ----------------------------
-- Table structure for module_role
-- ----------------------------
DROP TABLE IF EXISTS `module_role`;
CREATE TABLE `module_role` (
 `rid` int(11) DEFAULT NULL,`mid` int(11) DEFAULT NULL,KEY `rid` (`rid`),KEY `mid` (`mid`),CONSTRAINT `mid` FOREIGN KEY (`mid`) REFERENCES `module` (`mid`),CONSTRAINT `rid` FOREIGN KEY (`rid`) REFERENCES `role` (`rid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of module_role
-- ----------------------------
INSERT INTO `module_role` VALUES ('1','1');
INSERT INTO `module_role` VALUES ('1','2');
INSERT INTO `module_role` VALUES ('1','3');
INSERT INTO `module_role` VALUES ('1','4');
INSERT INTO `module_role` VALUES ('2','1');
INSERT INTO `module_role` VALUES ('2','3');
-- ----------------------------
-- Table structure for role
-- ----------------------------
DROP TABLE IF EXISTS `role`;
CREATE TABLE `role` (
 `rid` int(11) NOT NULL AUTO_INCREMENT,`rname` varchar(255) DEFAULT NULL,PRIMARY KEY (`rid`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of role
-- ----------------------------
INSERT INTO `role` VALUES ('1','admin');
INSERT INTO `role` VALUES ('2','customer');
-- ----------------------------
-- Table structure for user
-- ----------------------------
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
 `uid` int(11) NOT NULL AUTO_INCREMENT,`username` varchar(255) DEFAULT NULL,`password` varchar(255) DEFAULT NULL,PRIMARY KEY (`uid`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of user
-- ----------------------------
INSERT INTO `user` VALUES ('1','hlhdidi','123');
INSERT INTO `user` VALUES ('2','xyycici','1992');
-- ----------------------------
-- Table structure for user_role
-- ----------------------------
DROP TABLE IF EXISTS `user_role`;
CREATE TABLE `user_role` (
 `uid` int(11) DEFAULT NULL,`rid` int(11) DEFAULT NULL,KEY `u_fk` (`uid`),KEY `r_fk` (`rid`),CONSTRAINT `r_fk` FOREIGN KEY (`rid`) REFERENCES `role` (`rid`),CONSTRAINT `u_fk` FOREIGN KEY (`uid`) REFERENCES `user` (`uid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of user_role
-- ----------------------------
INSERT INTO `user_role` VALUES ('1','1');
INSERT INTO `user_role` VALUES ('2','2');

　　2.建立Maven工程,建立实体类,搭建mybatis开发环境

　　maven工程的基本目录如下:

　　为了方便,直接在父工程中,导入全部的依赖:
