Hibernate 4 javax / transaction / SystemException错误 [英] Hibernate 4 javax/transaction/SystemException error

问题描述

我试图让Hibernate 4.3与我的MySQL数据库一起工作。我已经能够在Eclipse中使用Hibernate Code Generation工具，并且我也可以使用Hibernate Configurations工具连接到数据库。

然而，当我尝试运行代码在我的Main类中查询数据库我得到以下错误：

 线程main中的异常java.lang.NoClassDefFoundError ：在java.lang.Class.forName0中的javax / transaction / SystemException

我的HibernateUtil.java文件中的代码是：

  import org.apache.commons.lang3.SystemUtils; 
 import org.hibernate.HibernateException; 
 import org.hibernate.SessionFactory; 
导入org.hibernate.cfg.Configuration; 
 import org.hibernate.service.ServiceRegistry; 
 import org.hibernate.service.ServiceRegistryBuilder; 
 
 public class HibernateUtil {
 
 private static final SessionFactory sessionFactoryBalie = new Configuration（）。configure（mysql_balie.cfg.xml）。buildSessionFactory（）; 
 
 public static SessionFactory getSessionFactoryBalie（）{
 return sessionFactoryBalie; 
} 
 
} 
  

mysq_balie.cfg.xml文件看起来像：

 <？xml version =1.0encoding =UTF-8？> 
<！DOCTYPE hibernate-configuration PUBLIC

我无法弄清楚错误可能在哪里。欢迎所有帮助。

I am trying to get Hibernate 4.3 to work with my MySQL database. I am already able to use the Hibernate Code Generation tool in Eclipse and I am also able to connect to the database using the Hibernate Configurations tool.

However when I try to run code in my Main class that queries the database I get the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: javax/transaction/SystemException

The code in my HibernateUtil.java file is:

import org.apache.commons.lang3.SystemUtils;
import org.hibernate.HibernateException;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;

public class HibernateUtil {

private static final SessionFactory sessionFactoryBalie = new Configuration().configure("mysql_balie.cfg.xml").buildSessionFactory();

public static SessionFactory getSessionFactoryBalie() {
    return sessionFactoryBalie;
}

}

The mysq_balie.cfg.xml file looks like:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC

    <!-- Echo all executed SQL to stdout -->

    <!-- List of XML mapping files -->
    <mapping resource="be/comp/model/balie/Zitdagen.hbm.xml"/>
</session-factory>

I am unable to figure out where the error might be. All help is welcome. Thanks.

解决方案

you are missing jta.jar
with maven add this dep:

  <dependency>
      <groupId>javax.transaction</groupId>
      <artifactId>jta</artifactId>
      <version>1.1</version>
  </dependency>

or download from maven repository and add to your CLASSPATH
