我需要与 GWT ( Google ) 一起研究 hibernate 和 Springs。
这是我的休眠配置文件..
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property>
<property name="hibernate.connection.username">root</property>
<mapping class="com.AAA" />
</session-factory>
</hibernate-configuration>
这是模型类
@Entity
public class AAA {
@Id@GeneratedValue(strategy=GenerationType.AUTO)
private int id;
private String Name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return Name;
}
public void setName(String name) {
Name = name;
}
}
这是我的主要课程
公共静态无效主要(字符串arg []){
SessionFactory sessionFactory=new AnnotationConfiguration().configure().buildSessionFactory();
Session hibernate_session = ((org.hibernate.SessionFactory) sessionFactory).openSession();
hibernate_session.beginTransaction();
System.out.println("Inside..");
AAA pr = (AAA)hibernate_session.get(AAA.class,2);
hibernate_session.getTransaction().commit();
hibernate_session.close();
System.out.println("Out sideee..");
}
这是不断出现的错误,即使`Asm.jar文件的不同版本发生了变化。

这些是我正在使用的以下主要罐子。
asm-3.1.jar
cglib-2.1.3.jar
hibernate3
spring.jar
hibernate-jpa-2.0-api-1.0.1.final.jar
如果我在动态 web 项目中使用这些 jars,一切都很好,但在 GWT webapplication 的情况下它不是......
请给出一些想法来实现它,
