这里采用第三方实现好的JdbcRealm连接数据库；首先来看一下源码；
接着前面的说；就把这个类当做我们自己写的就好了，我们需要实例化它，然后给他注入一个数据源
下面是ini文件配置
[main] #采用第三方JdbcRealm连接数据库 jdbcRealm=org.apache.shiro.realm.jdbc.JdbcRealm #实例化数据源 dataSource=com.alibaba.druid.pool.DruidDataSource #设置参数 dataSource.driverClassName=com.mysql.jdbc.Driver dataSource.url=jdbc:mysql://localhost:3306/shiro dataSource.username=root dataSource.password=root #将数据源设置到realm中 jdbcRealm.dataSource=$dataSource jdbcRealm.permissionsLookupEnabled=true securityManager.realms=$jdbcRealm
下面是sql脚本；大家测试可以直接复制去数据库执行

下面是测试代码

下面的代码是将ini文件彻底转换为java代码
package com; import com.alibaba.druid.pool.DruidDataSource; import org.apache.shiro.SecurityUtils; import org.apache.shiro.authc.UsernamePasswordToken; import org.apache.shiro.config.IniSecurityManagerFactory; import org.apache.shiro.mgt.SecurityManager; import org.apache.shiro.realm.jdbc.JdbcRealm; import org.apache.shiro.subject.Subject; import org.apache.shiro.util.Factory; public class TestShiro { public static void main(String[] args) { Factory<SecurityManager> factory = new IniSecurityManagerFactory(); SecurityManager instance = factory.getInstance(); JdbcRealm realm = new JdbcRealm(); DruidDataSource dataSource = new DruidDataSource(); dataSource.setDriverClassName("com.mysql.jdbc.Driver"); dataSource.setUrl("mysql://localhost:3306/shiro"); dataSource.setUsername("root"); dataSource.setPassword("root"); realm.setDataSource(dataSource); realm.setPermissionsLookupEnabled(true); SecurityUtils.setSecurityManager(instance); Subject subject = SecurityUtils.getSubject(); UsernamePasswordToken token = new UsernamePasswordToken("admin", "666"); subject.login(token); } }
