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:

可以看出这里采用的是阿里巴巴的Druid数据库.在spring-boot-shiro-web下建立application.properties文件.它主要配置对于数据库信息和jsp的支持:

##tomcat##
server.tomcat.uri-encoding=UTF-8
##Druid##
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test?characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.initialSize=5
spring.datasource.minIdle=5
spring.datasource.maxActive=20
spring.datasource.maxWait=60000
spring.datasource.timeBetweenEvictionRunsMillis=60000
spring.datasource.minEvictableIdleTimeMillis=300000
spring.datasource.validationQuery=SELECT 1 FROM DUAL
spring.datasource.testWhileIdle=true
spring.datasource.testOnBorrow=false
spring.datasource.testOnReturn=false
spring.datasource.poolPreparedStatements=true
spring.datasource.maxPoolPreparedStatementPerConnectionSize=20
spring.datasource.filters=stat,wall,log4j
spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
spring.datasource.useGlobalDataSourceStat=true
##jsp##
spring.mvc.view.prefix=/jsp/
spring.mvc.view.suffix=.jsp

在spring-boot-shiro-web下建立数据库连接池的配置类完成对于数据库连接池的配置:

/**
 * 数据库连接池&Mybatis配置类
 * @author Administrator
 *
 */
@Configuration
public class DruidConfiguation {
    @Bean
    public ServletRegistrationBean statViewServle(){
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
        //白名单：
        servletRegistrationBean.addInitParameter("allow","192.168.1.218,127.0.0.1");
        //IP黑名单 (存在共同时，deny优先于allow) : 如果满足deny的即提示:Sorry, you are not permitted to view this page.
        servletRegistrationBean.addInitParameter("deny","192.168.1.100");
        //登录查看信息的账号密码.
        servletRegistrationBean.addInitParameter("loginUsername","druid");
        servletRegistrationBean.addInitParameter("loginPassword","12345678");
        //是否能够重置数据.
        servletRegistrationBean.addInitParameter("resetEnable","false");
        return servletRegistrationBean;
    }

    @Bean
    public FilterRegistrationBean statFilter(){
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
        //添加过滤规则.
        filterRegistrationBean.addUrlPatterns("/*");
        //添加不需要忽略的格式信息.
        filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
        return filterRegistrationBean;
        }
    @Bean
    PersistenceExceptionTranslationPostProcessor persistenceExceptionTranslationPostProcessor(){
        return new PersistenceExceptionTranslationPostProcessor();
    }
    //配置数据库的基本链接信息
    @Bean(name = "dataSource")
     @Primary
     @ConfigurationProperties(prefix = "spring.datasource")    //可以在application.properties中直接导入
     public DataSource dataSource(){
         return DataSourceBuilder.create().type(com.alibaba.druid.pool.DruidDataSource.class).build();
     }
    @Bean
     public SqlSessionFactoryBean sqlSessionFactory(@Qualifier("dataSource") DataSource dataSource) {
         SqlSessionFactoryBean bean=new SqlSessionFactoryBean();
         bean.setDataSource(dataSource);
         return bean;
     }

}

接着在spring-boot-shiro-web下建立Application类:

@SpringBootApplication
@EnableTransactionManagement
@MapperScan("com.xyy.springboot.shiro.mapper")//配置mybatis包扫描
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

紧接着,我们根据数据库的表结构在spring-boot-shiro-dao的项目下建立实体类User,Role,Module.它们的意义在上文中已经说明了:

接着就可以书写mapper了,注意,mapper所在的位置需要和Application类中配置的包扫描的位置保持一致,我们的需求是根据用户名在数据库中查询出指定的用户表的记录,与此同时查询出对应的角色以及角色所对应的权限,并且封装到实体类User中.UserMapper接口如下:

　　UserMapper.xml如下:

<mapper namespace="com.xyy.springboot.shiro.mapper.UserMapper">
    <resultMap type="com.xyy.springboot.shiro.pojo.User" id="userMap">
        <id property="uid" column="uid"/>
        <result property="username" column="username"/>
        <result property="password" column="password"/>
        <collection property="roles" ofType="com.xyy.springboot.shiro.pojo.Role">
            <id property="rid" column="rid"/>
            <result property="rname" column="rname"/>
            <collection property="modules" ofType="com.xyy.springboot.shiro.pojo.Module">
                <id property="mid" column="mid"/>
                <result property="mname" column="mname"/>
            </collection>
        </collection>
    </resultMap>
    <select id="findByUserName" parameterType="string" resultMap="userMap">
        SELECT u.*,r.*,m.* FROM user u inner join user_role ur on ur.uid=u.uid 
        inner join role r on r.rid=ur.rid
        inner join module_role mr on mr.rid=r.rid 
        inner join module m on mr.mid=m.mid 
        WHERE username=#{username};
    </select>
</mapper>

在spring-boot-shiro-service建立UserService和UserServiceImpl,完成业务层对于mapper的调用:
