第一：导包
第二：书写 shiro.ini 文件
[users] DQC=123 DQCGM=root第三：书写测试代码
package com.shiro1; import org.apache.shiro.SecurityUtils; import org.apache.shiro.authc.AuthenticationException; 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.realm.jdbc.JdbcRealm; import org.apache.shiro.subject.Subject; import org.apache.shiro.util.Factory; import org.apache.shiro.mgt.SecurityManager; public class TestA { public static void main(String[] args) { //[1]解析shiro.ini文件 Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.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("DQC", "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"); } } }运行结果：
