Hibernate 3.6:架构导出失败，autocommit=false？

我正在阅读关于模式导出的hibernate书籍：

我试着在Hibernate 3.6中运行代码，但是没有创建模式，并且假设从输出日志来看，可能没有提交模式。以下是日志输出：

105 [main] INFO org.hibernate.annotations.common.Version - Hibernate Commons Annotations 3.2.0.Final

347 [main] INFO org.hibernate.connection.DriverManagerConnectionProvider - cleaning up connection pool: jdbc:postgresql://localhost:5432/hibernate

这是我的密码：

import javax.persistence.GeneratedValue;
import javax.persistence.Id;

import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.cfg.Configuration;
import org.hibernate.tool.hbm2ddl.SchemaExport;


public class User {
    private Long id;
    private String name;

    @Id
    @GeneratedValue
    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    /**
     * @param args
     */
    public static void main(String[] args) {
        Configuration config = new Configuration();
        config.addAnnotatedClass(User.class);
        config.configure();
        new SchemaExport(config).create(true, true);
    }
}

下面是我的hibernate cfg xml：

<?xml version='1.0' encoding='utf-8'?>

    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

我想知道我在这里错过了什么

问候,

日志中似乎缺少一些内容，但可能是因为您没有用@entity标记实体

哇！我怎么会错过这个！哈哈。现在很好用了，谢谢你。尽管如此，在postgresql 9中创建表名user似乎有问题。将类名更改为MstUser后，它可以正常工作。以下是日志：drop table MstUser cascade。。删除序列休眠\u序列。。创建表MstUser（id int8非null，名称varchar（255），主键（id））。。创建序列休眠\u序列。。542[main]INFO org.hibernate.tool.hbm2ddl.SchemaExport-模式导出完成..“User”是PostgreSQL（可能还有Oracle）中的保留关键字。您不需要更改类名（也不应该更改）。只需引用@Entity（table=“

user

”）即可。我昨天也发现了这个注释。。谢谢！：）
