Shiro学习笔记（2）--jdbcRealm

1、创建一个简单的maven项目

2、在数据库创建要验证的表

表名（users）和字段名要与图片一致

3、在pom.xml中配置shiro所依赖的jar包

 <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>
	/* 数据源 */
	<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>
	/*数据库连接驱动*/
	<dependency>
		<groupId>mysql</groupId>
		<artifactId>mysql-connector-java</artifactId>
		<version>5.1.37</version>
	</dependency>
	
  </dependencies>

4、配置log4j文件（同第一节）

5、配置jdbc_realm.ini文件

[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

5、创建验证实现类JdbcRealmTest.java

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) {
		// 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实例绑定到SecurityUtils
		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("yang", "123");
		try{
			// 身份认证
			currentUser.login(token);	
			System.out.println("身份认证成功！");
		}catch(AuthenticationException e){
			e.printStackTrace();
			System.out.println("身份认证失败！");
		}
		// 退出
		currentUser.logout();
	}
}
