导包： 数据库创建（表必须是这样的一点都不能错）： 实现代码：
package com.shiro1; import org.apache.shiro.SecurityUtils; import org.apache.shiro.authc.IncorrectCredentialsException; import org.apache.shiro.authc.UnknownAccountException; import org.apache.shiro.authc.UsernamePasswordToken; import org.apache.shiro.config.IniSecurityManagerFactory; import org.apache.shiro.mgt.SecurityManager; import org.apache.shiro.subject.Subject; import org.apache.shiro.util.Factory; public class TestB { public static void main(String[] args) { //[1]解析shiro.ini文件 Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro-jdbc.ini"); //[2]通过SecurityManager工厂获得SecurityManager实例 SecurityManager securityManager = factory.getInstance(); //[3]把SecurityManager对象设置到运行环境中 SecurityUtils.setSecurityManager(securityManager); //[4]通过SecurityUtils获得主体subject Subject subject = SecurityUtils.getSubject(); //[5]书写自己输入的账号和密码---相当于用户自己输入的账号和密码 //我们拿着自己书写用户名密码去和shiro.ini 文件中的账号密码比较 UsernamePasswordToken token = new UsernamePasswordToken("DQCGM", "123"); try { //[6]进行身份的验证 subject.login(token); //[7]通过方法判断是否登录成功 if (subject.isAuthenticated()) { System.out.println("登录成功"); } } catch (IncorrectCredentialsException e) { System.out.println("登录失败"); } catch (UnknownAccountException e) { System.out.println("用户名不正确"); } } } [main] dataSou=com.mchange.v2.c3p0.ComboPooledDataSource dataSou.driverClass=com.mysql.jdbc.Driver dataSou.jdbcUrl=jdbc:mysql://127.0.0.1:3306/shiro dataSou.user=root dataSou.password=Root jdbcRealm=org.apache.shiro.realm.jdbc.JdbcRealm jdbcRealm.dataSource=$dataSou securityManager.realm=$jdbcRealm运行结果：
