全部三个例子只需要更改配置验证器最后的认证策略就行了
导包:
数据库创建:
[main]
#获得数据源A
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
#配置了jdbcRealmA
jdbcRealm=org.apache.shiro.realm.jdbc.JdbcRealm
jdbcRealm.dataSource=$dataSou
#获得数据源B
dataSou1=com.mchange.v2.c3p0.ComboPooledDataSource
dataSou1.driverClass=com.mysql.jdbc.Driver

import org.apache.shiro.subject.Subject;
import org.apache.shiro.util.Factory;
public class TestA {
public static void main(String[] args) {

//[2]通过SecurityManager工厂获得SecurityManager实例

//[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

//[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("DQC", "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");
}
}
}
