hibernate 中 Error calling Driver#的问题如何解决

[nanguyan]

这是测试的代码：

import hibernate_1.User;

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

public class HibernateDemo {
@Test
public void testAdd(){
//第一步加载核心配置文件
Configuration cfg=new Configuration();//创建 cfg对象
cfg.configure();//用对象加载配置文件
// 第二步 创建SessionFactory
//读取核心配置文件内容，过程中，根据映射关系，在配置数据库里创建表
SessionFactory sf=cfg.buildSessionFactory();
// 第三步 使用SessionFactory创建session对象
//类似于数据库链接
Session se=sf.openSession();
// 第四部 开启事务
Transaction tx=se.beginTransaction();
// 第五步 写具体逻辑crud操作
User user=new User();
user.setName("林青霞");
user.setAddress("祥云镇");
user.setMale("女");
se.save(user);
// 第六步 提交事务
tx.commit();
// 第七步 关闭资源
se.close();
sf.close();
}
}

下面是实体类代码：

package hibernate_1;

public class User {
private int uid;
private String name;
private String address;
private String male;
public int getUid() {
return uid;
}
public void setUid(int uid) {
this.uid = uid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getMale() {
return male;
}
public void setMale(String male) {
this.male = male;
}
}

下面是映射文件代码

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<!-- 映射配置文件对位置和名称无要求，但是建议：位置在实体类的包下；名字为 类名.hbm.xml -->
<hibernate-mapping>
<!-- name属性的值为实体类的全路径，即：包.类 -->
<class name="hibernate_1.User" table="t_user">
<!-- id和property的column属性可以不用配置，默认会与实体类的属性名称相同 -->
<id name="uid" column="uid">
<!-- 设置主键自增长 -->
<generator class="native"></generator>
</id>
<!-- property里有Type属性，表示生成表的字段类型，默认与实体类的类型对应 -->
<property name="name" column="name"></property>
<property name="address" column="address"></property>
<property name="male" column="male"></property>
</class>
</hibernate-mapping>

下面是jebernate.cfg.xml的代码
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- 第一部分：配置数据库信息 -->
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql:///family</property>
<property name="hibernate.connertion.username">root</property>
<property name="hibernate.connertion.password">123</property>

<!-- 第二部分：配置hibernate信息，可选的 -->
<!--输出底层sql语句 -->
<property name="hibernate.show_sql">true</property>
<!--输出底层sql语句格式 -->
<property name="hibernste.format_sql">true</property>
<!--hibernate帮创建表，需要在配置之后
update:如果有表，更新；如果没表，创建 -->
<property name="hibernate.hbm2ddl.auto">update</property>
<!--配置数据库方言 让hibernate识别不同数据库特有的方言-->
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>

<!--第三部分：把映射文件放到核心配置文件中 -->
<mapping resource="hibernate_1/User.hbm.xml"/>
</session-factory>
</hibernate-configuration>

之前用的是hibernate5.0.12的版本，会出现Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]；换成4.3.11之后就又报这个错，版本太乱搞晕了。

[李德胜1995]

Access denied for user ''@'localhost' (using password: NO)....密码错了？？？

<property name="hibernate.connertion.username">root</property> <property name="hibernate.connertion.password">123</property> 拼写都写错了，，，不是有提示吗？？？connection。。。。

[justdoit026]

把驱动jar包换成数据库可以用的版本包就可以了，jar包版本太高会包报这个错误。

你的 <property name="hibernate.connertion.username">root</property> <property name="hibernate.connertion.password">123</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.connection.password">123</property> 注意connection
