JdbcRealm测试

package com.shiro.test;

import com.alibaba.druid.pool.DruidDataSource;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authc.credential.HashedCredentialsMatcher;
import org.apache.shiro.mgt.DefaultSecurityManager;
import org.apache.shiro.realm.jdbc.JdbcRealm;
import org.apache.shiro.subject.Subject;
import org.junit.Test;

public class JdbcRealmTest {

    DruidDataSource dataSource = new DruidDataSource();

    {
        dataSource.setUrl("jdbc:mysql://localhost:3306/shiro");
        dataSource.setUsername("root");
        dataSource.setPassword("123456");
    }

    @Test
    public void testAuthentication(){

        JdbcRealm jdbcRealm = new JdbcRealm();
        jdbcRealm.setDataSource(dataSource);
        jdbcRealm.setPermissionsLookupEnabled(true);

        String sql = "select password from test_user where user_name = ?";
        jdbcRealm.setAuthenticationQuery(sql);

        //1.构建securityManager环境
        DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
        defaultSecurityManager.setRealm(jdbcRealm);

        //2.主体提交认证请求
        SecurityUtils.setSecurityManager(defaultSecurityManager);
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken("Alax","654321");

        subject.login(token);
        System.out.println(token.getUsername()+" isAuthenticated:"+subject.isAuthenticated());

        subject.checkRole("admin");
        subject.checkPermission("user:select");

        subject.logout();
        System.out.println(token.getUsername()+" isAuthenticated:"+subject.isAuthenticated());

    }
}
