hibernate错误搞了一天没搞懂

[已解决问题] 解决于 2017-05-06 09:44

//这是测试的代码
package hibernatetest;
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>

下面是项目截图：

这个类18行是什么？

SessionFactory sf=cfg.buildSessionFactory();

@南孤雁: Caused by: java.sql.SQLException: Access denied for user ''@'localhost' (using password: NO)

感觉是hibernate配置文件有问题，看看数据库密码对不

揽星 | 园豆：207 (菜鸟二级) | 2017-05-04 16:15

@揽星: 检查好几遍了，这些都没问题，帐号密码在cmd都能访问的。网上查的同类问题说是hibernate的版本问题。引用了4的版本和5的版本都报错，但是报出来的错误不一样，蒙圈了啊

南孤雁 | 园豆：192 (初学一级) | 2017-05-04 20:23

@南孤雁: 把你项目给我发来，我试试看！

@揽星: 你邮箱多少啊博客园里面没有找到上传文件的地方

东西发过去了，抱歉刚才才看见邮件，不好意思了

揽星 | 园豆：207 (菜鸟二级) | 2017-05-05 21:31

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

connertion
这个单词写错了，应该是connection的

揽星 | 园豆：207 (菜鸟二级) | 2017-05-05 21:31

以后还是把做成功一次的保存起来，用的时候复制配置文件就好了，纯手打容易出错

揽星 | 园豆：207 (菜鸟二级) | 2017-05-05 21:35

@揽星: 我去太感谢你了我记得我是复制的就没有检查那里应该是复制的时候不小心碰到了。。。很感谢
