05、Shiro 入门:Shiro中的JDBCRealm

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:
