我目前正在尝试使用 Hibernate 部署示例 POJO Axis2 服务。为了避免在访问 hibernate.cfg.xml 时出现更多错误，我将我的服务分成了 2 个 Maven 项目。一个包含数据映射类和src/main/resources/hibernate.cfg.xml文件。
<?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>
<property name="connection.url">jdbc:postgresql://localhost/prueba_drools</property>
<property name="connection.username">prueba_drools</property>
<property name="connection.password">123456</property>
<property name="connection.driver_class">org.postgresql.Driver</property>
<property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>
<property name="show_sql">true</property>
<property name="format_sql">true</property>
<property name="hbm2ddl.auto">update</property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<property name="current_session_context_class">thread</property>
<mapping class="local.lunacore.axis2test.model.Piloto"/>
<mapping class="local.lunacore.axis2test.model.Robot"/>
<mapping class="local.lunacore.axis2test.model.TipoRobot"/>
</session-factory>
</hibernate-configuration>
另一个具有用作 Web 服务的 POJO。
package local.lunacore.axis2test;
import local.lunacore.axis2test.model.*;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.AnnotationConfiguration;
/**
* Hello world!
*
*/
public class Axis2TestService
{
public void seed()
{
SessionFactory sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
Session session = sessionFactory.getCurrentSession();
Transaction tx = session.beginTransaction();
TipoRobot tipoRobotMelee = new TipoRobot();
tipoRobotMelee.setNombre("Melee (Combate cuerpo a cuerpo)");
session.save(tipoRobotMelee);
TipoRobot tipoRobotArtilleria = new TipoRobot();
tipoRobotArtilleria.setNombre("Artillería");
session.save(tipoRobotArtilleria);
TipoRobot tipoRobotAereo = new TipoRobot();
tipoRobotAereo.setNombre("Aéreo");
session.save(tipoRobotAereo);
TipoRobot tipoRobotSoporte = new TipoRobot();
tipoRobotSoporte.setNombre("Soporte");
session.save(tipoRobotSoporte);
Robot robotGundamStrikeFreedom = new Robot();
robotGundamStrikeFreedom.setNombre("ZGMF-X20A Strike Freedom Gundam");
robotGundamStrikeFreedom.setTipoRobot(tipoRobotMelee);
session.save(robotGundamStrikeFreedom);
Robot robotGundamAileStrike = new Robot();
robotGundamAileStrike.setNombre("GAT-X105+AQM/E-X01 Aile Strike Gundam");
robotGundamAileStrike.setTipoRobot(tipoRobotAereo);
session.save(robotGundamAileStrike);
Piloto pilotoKiraYamato = new Piloto();
pilotoKiraYamato.setNombre("Kira Yamato");
pilotoKiraYamato.getRobots().add(robotGundamStrikeFreedom);
pilotoKiraYamato.getRobots().add(robotGundamAileStrike);
session.save(pilotoKiraYamato);
session.saveOrUpdate(robotGundamStrikeFreedom);
session.saveOrUpdate(robotGundamAileStrike);
tx.commit();
}
}
这是我的src/main/resources/META-INF/services.xml：
<serviceGroup>
<service name="Axis2TestService" targetNamespace="http://lunacore.local/axis2test" scope="application">
<schema schemaNamespace="http://lunacore.local/types" elementFormDefaultQualified="false"/>
<parameter
locked="true"
name="ServiceClass">local.lunacore.axis2test.Axis2TestService</parameter>
</service>
</serviceGroup>
数据模型 Maven 项目的单元测试表明 Hibernate 配置正确，可以从数据库中读取/创建数据模型。当我在 WSO2 AS 上部署它时，它部署没有错误，但是在调用该seed方法时，它崩溃了，并显示以下消息：
