shiro-用户认证-连接数据库

Javase程序用shiro连接数据库验证用户身份

1、创建数据库
2、导入jar包	版本要对好： c3p0-0.9.2.1.jar commons-beanutils-1.9.2.jar commons-logging-1.2.jar junit-4.10.jar log4j-1.2.17.jar mchange-commons-java-0.2.3.4.jar mysql-connector-java-5.1.48.jar shiro-all-1.2.3.jar slf4j-api-1.7.7.jar slf4j-log4j12-1.7.5.jar
3、新建shiro.ini	[main] dataSource=com.mchange.v2.c3p0.ComboPooledDataSource dataSource.driverClass=com.mysql.jdbc.Driver dataSource.jdbcUrl=jdbc:mysql://localhost:3306/myshiro dataSource.user=root dataSource.password=1234567 jdbcRealm=org.apache.shiro.realm.jdbc.JdbcRealm jdbcRealm.dataSource=$dataSource securityManager.realm=$jdbcRealm
4、log4j.properties	log4j.rootLogger=error,stdout log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m %n
5、JdbcRealmDemo.java	package com.pshdhx;   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.util.Factory; import org.apache.shiro.mgt.SecurityManager; import org.apache.shiro.subject.Subject;   public class JdbcRealmDemo {     public static void main(String[] args) {        Factory factory = new IniSecurityManagerFactory("classpath:shiro.ini");        SecurityManager securityManager = factory.getInstance();        SecurityUtils.setSecurityManager(securityManager);        Subject subject = SecurityUtils.getSubject();        UsernamePasswordToken token = new UsernamePasswordToken("zhangsan", "11211");        try {            subject.login(token);            if(subject.isAuthenticated()){               System.out.println("验证通过");            }        } catch (AuthenticationException e) {            System.out.println("验证失败");        }            } }
开始运行java程序	结果：验证成功、验证失败；
