我正在使用 Hibernate 4.1.9 创建一个简单的 Java 应用程序。我可以从数据库中检索数据，但是当我尝试插入新记录时，它们没有出现在表中，并且出现了一个我无法弄清楚的错误。
这是输出：

at org.mine.hibernateproject01.App.main(App.java:31)
这是代码
public static void main( String[] args )
{
Configuration config = new Configuration().configure();
ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(config.getProperties()).buildServiceRegistry();
SessionFactory sessionFactory = config.buildSessionFactory(serviceRegistry);
Session session = sessionFactory.openSession();
Transaction tx = null;
try {
tx = session.beginTransaction();
UserEntity u = new UserEntity("name","firstname");
session.save(u); <== error occur here
session.flush();
tx.commit();
} catch (Exception e) {
if(tx!=null){
tx.rollback();
}
System.err.println(e);
} finally{
session.close();
}
sessionFactory.close();
}
这是 hibernate.cfg.xml ：
<hibernate-configuration>
<session-factory>
<property name="connection.driver_class">sun.jdbc.odbc.JdbcOdbcDriver</property>
<property name="connection.url">jdbc:odbc:MySqlServer</property>
<property name="connection.username"></property>
<property name="connection.password"></property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
<!-- Enable Hibernate's automatic session context management -->
<property name="current_session_context_class">thread</property>
<!-- Disable the second-level cache -->
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<!-- Drop and re-create the database schema on startup -->
<!-- <property name="hbm2ddl.auto">create</property>-->
<mapping resource="org/mine/hibernateproject01/UserEntity.hbm.xml"/>
</session-factory>
</hibernate-configuration>
这是 UserEntity 类和配置：
public class UserEntity {
private int UserID;
private String UserName;
private String UserFirstName;
public UserEntity(){
}
public UserEntity(String UserName, String UserFirstName) {
this.UserName = UserName;
this.UserFirstName = UserFirstName;
}
public int getUserID() {
return UserID;
}
public void setUserID(int UserID) {
this.UserID = UserID;
}
public String getUserName() {
return UserName;
}
public void setUserName(String UserName) {
this.UserName = UserName;
}
public String getUserFirstName() {
return UserFirstName;
}
public void setUserFirstName(String UserFirstName) {
this.UserFirstName = UserFirstName;
}
}
<hibernate-mapping package="org.mine.hibernateproject01" schema="dbo">
<class name="UserEntity" table="T_USERLIST" lazy="false">
<id name="UserID" column="UserID" type="java.lang.Integer">
<generator class="identity"/>
</id>
<property name="UserName" column="UserName" type="java.lang.String" length="50" not-null="true"/>
<property name="UserFirstName" column="UserFirstName" type="java.lang.String" length="50" not-null="true"/>
</class>
</hibernate-mapping>
我可能做错了什么？
对此的任何建议或帮助都会很棒。
谢谢
