如何在 Hibernate 5 中从 xml 创建 table?
How to create table from xml in Hibernate 5?
我在此文件中保留 table 架构 tableaddress.orm.xml
<?xml version="1.0" encoding="UTF-8"?>
<entity-mappings version="2.1"
xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/orm"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<entity class="Address">
<attributes>
<basic name="city" attribute-type="String" />
<basic name="country" attribute-type="int" />
<basic name="province" attribute-type="double" />
<basic name="postalCode" attribute-type="boolean">
</basic>
<basic name="street" attribute-type="String" />
</attributes>
</entity>
</entity-mappings>
以下是我尝试使用 Hibernate
创建 table 的方法
public class App
{
public static void main( String[] args )
{
Properties prop= new Properties();
prop.setProperty("hibernate.connection.url", "jdbc:mariadb:......");
prop.setProperty("dialect", "org.hibernate.dialect.MariaDB53Dialect");
prop.setProperty("hibernate.connection.username", "user");
prop.setProperty("hibernate.connection.password", "password");
prop.setProperty("hibernate.connection.driver_class", "org.mariadb.jdbc.Driver");
SessionFactory sessionFactory = new Configuration()
.addResource("tableaddress.orm.xml").addProperties(prop).buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
session.getTransaction().commit();
session.close();
}
}
它应该可以工作,没有编译错误,但由于某种原因没有创建 table
错误java.lang.NoClassDefFoundError: javax/transaction/SystemException
这可能是由于 Hibernate 中的 bug/feature。
javax.transaction 在 5.0.4 中从 Hibernate 中移除(好吧,标记为 "provided"),但在 5.0.7 中又恢复了(参见 https://hibernate.atlassian.net/browse/HHH-10307:
"JTA no longer transitively provided (HHH-10178) causes problems for
apps not using JTA"
)
假设您使用的是 5.04、5.0.5 或 5.0.6,您的选择是升级 Hibernate,或添加以下依赖项:
<dependency>
<groupId>javax.transaction</groupId>
<artifactId>jta</artifactId>
<version>1.1</version>
</dependency>
