Question

我尝试使用MySQL将项目设置从SQL Server重建为Apache 2。我刚接触JDBC，无法弄清楚所有方面。

我根据本教程安装了MySQL / JDBC Driver Setting Up MySQL/JDBC Driver on Ubuntu 将此.jar文件添加到项目后，测试运行完美。

hibernate.cfg.xml的内容：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
                                         "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <!-- /MYPC:1433/Blog;instance=SQLEXPRESS local connection properties -->
        <property name="hibernate.connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property>
        <property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
        <!--<property name="hibernate.connection.url">jdbc:jtds:sqlserver://streamer2005.softserveinc.com/_055_OMS;instance=tc;</property>-->
        <property name="hibernate.connection.url">jdbc:jtds:mysql://nazar_art/_056_DB;instance=MYSQL;</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">nazarsql</property>

        <!--<property name="hibernate.hbm2ddl.auto">create</property>-->

        <!-- <property name="show_sql">true</property> <property name="format_sql">true</property> -->
        <mapping class="com.softserveinc.edu.oms.domain.entities.Role" />
        <mapping class="com.softserveinc.edu.oms.domain.entities.Region" />
        <mapping class="com.softserveinc.edu.oms.domain.entities.CustomerType" />
        <mapping class="com.softserveinc.edu.oms.domain.entities.User" />
        <mapping class="com.softserveinc.edu.oms.domain.entities.OrderStatus" />
        <mapping class="com.softserveinc.edu.oms.domain.entities.Order" />
        <mapping class="com.softserveinc.edu.oms.domain.entities.Product" />
        <mapping class="com.softserveinc.edu.oms.domain.entities.Dimension" />
        <mapping class="com.softserveinc.edu.oms.domain.entities.OrderItem" />
        <mapping class="com.softserveinc.edu.oms.domain.entities.CreditCardType" />
    </session-factory>
</hibernate-configuration>

但是当我从maven运行它失败时，这不能正常工作如何解决这个问题？

您使用的是Sql server还是MySql？。如果是MySql，则将方言类型更改为MySQLDialect

<property name="dialect">org.hibernate.dialect.MySQLDialect</property>

在Ubuntu 12.04上为MySQL配置hibernate.cfg.xml
