java1234 shiro 第2 課 jdbc. realm 編寫

一.新建一個mave項目: 結構以下

pom.xml

 <dependencies>
      <dependency>
        <groupId>org.apache.shiro</groupId>
        <artifactId>shiro-core</artifactId>
        <version>1.2.4</version>
    </dependency>
    
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.7.12</version>
    </dependency>
    
    <dependency>
        <groupId>c3p0</groupId>
        <artifactId>c3p0</artifactId>
        <version>0.9.1.2</version>
    </dependency>
    
    <dependency>
        <groupId>commons-logging</groupId>
        <artifactId>commons-logging</artifactId>
        <version>1.2</version>
    </dependency>
    
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.37</version>
    </dependency>
    
  </dependencies>

  shiro.ini

[main]
jdbcRealm=org.apache.shiro.realm.jdbc.JdbcRealm
dataSource=com.mchange.v2.c3p0.ComboPooledDataSource
dataSource.driverClass=com.mysql.jdbc.Driver
dataSource.jdbcUrl=jdbc:mysql://localhost:3306/db_shiro
dataSource.user=root
dataSource.password=123456
jdbcRealm.dataSource=$dataSource
securityManager.realms=$jdbcRealm

向數據添加以下代碼:

CREATE DATABASE /*!32312 IF NOT EXISTS*/`db_shiro` /*!40100 DEFAULT CHARACTER SET utf8 */;
USE `db_shiro`;
/*Table structure for table `users` */
DROP TABLE IF EXISTS `users`;
CREATE TABLE `users` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `userName` varchar(20) DEFAULT NULL,
  `password` varchar(20) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
/*Data for the table `users` */
insert  into `users`(`id`,`userName`,`password`) values (1,'java1234','123456');

JdbcRealmTest.java

package com.java1234.shiro;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;
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 JdbcRealmTest {

	public static void main(String[] args) {
		// 讀取配置文件，初始化SecurityManager工廠
		Factory<SecurityManager> factory=new IniSecurityManagerFactory("classpath:jdbc_realm.ini");
		// 獲取securityManager實例
		SecurityManager securityManager=factory.getInstance();
		// 把securityManager實例綁定到SecurityUtils
		SecurityUtils.setSecurityManager(securityManager);
		// 獲得當前執行的用戶
		Subject currentUser=SecurityUtils.getSubject();
		// 建立token令牌，用戶名/密碼
		UsernamePasswordToken token=new UsernamePasswordToken("java1234", "123456");
		try{
			// 身份認證
			currentUser.login(token);	
			System.out.println("身份認證成功！");
		}catch(AuthenticationException e){
			e.printStackTrace();
			System.out.println("身份認證失敗！");
		}
		// 退出
		currentUser.logout();
	}
}

 

 打印結果:
