这个是什么原因 是不是我的那个配置文档有问题？
我看了 但是还是没有找出来
大家帮忙看看 谢谢了

好象是数据库连接失败 应该是hibernate.cfg.xml中配置的问题吧

<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://hibernate.

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql:///test</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">1</property>

这个是我写的
帮忙看看 谢谢了

<property name="hibernate.connection.url">jdbc:mysql:///test</property>
看看错了没。。。。。

在Hibernate中测试下，可能是MySQL的服务没有启动...没有对应的进程

我更改了 还是不可以<property name="hibernate.connection.url">jdbc:mysql://localhost:3360/test</property>
我打包了 你帮忙看看吧

我在任务管理器里看到了MYSQL进程
并且我也打开mysql 查看了数据库

谢谢了

jdbc:mysql://localhost:3306/test
是端口是3306 不是3360

问题已经解决
数据库连接没有问题
<property name="hibernate.connection.url">jdbc:mysql:///test</property>
这句没有错

错在是我

        <property name="hibernate.connection.password">1</property>
        
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        
        <property name="hibernate.connection.password"></property>
多写了<property name="hibernate.connection.password"></property>
没有提供密码
应该改为<property name="hibernate.connection.password">1</property>

谢谢大家了

: java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: NO)

这个已经提示了
