JdbcRealmTest.java

package shiro;

import org.apache.shiro.config.IniSecurityManagerFactory;
import org.apache.shiro.util.Factory;
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.subject.Subject;

public class JdbcRealmTest {

public static void main(String[] args) {
// 读取配置文件,初始化SecurityManager工厂
Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:jdbc_realm.ini");
// 获取securityManager实例
SecurityManager securityManager = factory.getInstance();
// 把securityManager绑定到SecurityUtils中
SecurityUtils.setSecurityManager(securityManager);
// 得到当前执行的用户
Subject currentUser =  SecurityUtils.getSubject();
// 创建token令牌,用户名/密码
UsernamePasswordToken token = new UsernamePasswordToken("java1234","123456");
// 身份验证
try{
currentUser.login(token);
System.out.println("身份验证成功");
}catch(Exception e){
e.printStackTrace();
System.out.println("身份验证失败");
}
currentUser.logout();//退出

}

}
