hibernate连接数据库报错

10

这是hibernate.cfg.xml配置文件,用户名和密码都用jdbc测试过可以连接上

 <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.uesrname">root</property>
        <property name="hibernate.connection.password">liangqichan</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/cql1</property>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>

        <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>
        <property name="hibernate.hbm2ddl.auto">update</property>
        <property name="hibernate.show_sql">true</property>
        <mapping resource="com/cql/crm/domain/SysUserGroup.hbm.xml"/>

    </session-factory>
</hibernate-configuration>

这是报错信息:

补充:
这是我测试hibernate时的代码
package junit;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.junit.Test;

import com.cql.crm.domain.SysUserGroup;

public class TestHibernate {

@Test
public void testHibernateConf(){
    Configuration config=new Configuration();
    //config.configure("hibernate.cfg.xml");
    config.configure();
    SessionFactory sf=config.buildSessionFactory();
    Session s=sf.openSession();
    Transaction tx=s.beginTransaction();
    SysUserGroup sysUserGroup=new SysUserGroup();
    sysUserGroup.getName();
    sysUserGroup.getPrincipal();
    sysUserGroup.getIncumbent();
    s.save(sysUserGroup);
    tx.commit();
    s.close();

}

}

这是我jdbc连接时的代码:
public class jdbc {
public static void main(String[] args) {
String url="jdbc:mysql://localhost:3306/cql";
String user="root";
String password="liangqichan";
String sql="Select * from sys_user_group";
Connection conn=null;
Statement st=null;
ResultSet rs=null;
try {
conn=(Connection) DriverManager.getConnection(url, user, password);
st=(Statement) conn.createStatement();
rs=st.executeQuery(sql);

        while(rs.next()){
            System.out.println(rs.getString("id"));
            System.out.println(rs.getString("name"));
            System.out.println(rs.getString("remark"));
        }

        rs.close();
        st.close();
        conn.close();
    } catch (SQLException e) {
        // TODO 自动生成的 catch 块
        e.printStackTrace();
    }


}

}
