Question

我正在阅读有关架构导出的hibernate书籍： http://jpa.ezhibernate.com/Javacode/learn.jsp?tutorial=02validatingthehibernateenvironment

我尝试在Hibernate 3.6中运行代码，但是没有创建架构，并且从输出日志中假设，也许它不会以某种方式提交。这是日志输出：

105 [main] INFO org.hibernate.annotations.common.Version - Hibernate Commons Annotations 3.2.0.Final
118 [main] INFO org.hibernate.cfg.Environment - Hibernate 3.6.0.Final
119 [main] INFO org.hibernate.cfg.Environment - hibernate.properties not found

346 [main] INFO org.hibernate.tool.hbm2ddl.SchemaExport - schema export complete
347 [main] INFO org.hibernate.connection.DriverManagerConnectionProvider - cleaning up connection pool: jdbc:postgresql://localhost:5432/hibernate

这是我的代码：

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);
    }
}

这是我的hibernate cfg xml：

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>

    <!--    MOHON DITAMBAHKAN SESUAI PACKAGE DAN URUT ABJAD -->

    <session-factory>
        <property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>
        <property name="connection.driver_class">org.postgresql.Driver</property>
        <property name="connection.username">sofco</property>
        <property name="connection.password">kamalbert</property>
        <property name="connection.url">jdbc:postgresql://localhost:5432/hibernate</property>
        <property name="show_sql">true</property>
        <property name="transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>
        <property name="current_session_context_class">thread</property>
    </session-factory>

</hibernate-configuration>

我想知道我在这里失踪了什么..

此致

似乎日志中缺少一些东西，但可能是因为你没有用@Entity标记你的实体。
