//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>

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 | 园豆:207 (菜鸟二级) | 2017-05-04 20:24

@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

 <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
