Question

我是Hibernate配置的新手，我正在尝试设置这个测试应用程序，但是我遇到了一些问题。我在本教程中做了所有事情： http://www.laliluna.de/articles/java-persistence-hibernate/first-hibernate-example-tutorial.html但似乎我做错了什么：

见日志：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation

我得到了以下配置：

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

<!-- Generated by MyEclipse Hibernate Tools.                   -->
<hibernate-configuration>

  <session-factory>
    <!--  PostgreSQL connection -->
    <property name="connection.url">jdbc:postgresql://localhost:5432/firsthibernate</property>
    <property name="connection.username">postgres</property>
    <property name="connection.password">root</property>
    <property name="connection.driver_class">org.postgresql.Driver</property>
    <property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>


    <property name="transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>
    <!--  thread is the short name for
      org.hibernate.context.ThreadLocalSessionContext
      and let Hibernate bind the session automatically to the thread
    -->
    <property name="current_session_context_class">thread</property>
    <!-- this will show us all sql statements -->
    <property name="hibernate.show_sql">true</property>
    <!-- this will create the database tables for us -->
    <property name="hibernate.hbm2ddl.auto">create</property>
    <!--<mapping resource="de/laliluna/example/Honey.hbm.xml" />-->
    <mapping class="de.laliluna.example.Honey" />


  </session-factory>

</hibernate-configuration>

类映射：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >
<hibernate-mapping package="de.laliluna.example">
    <class name="Honey" table="thoney">
        <id name="id">
            <!--  PostgreSQL generator for a sequence which is named honey_id_seq
            -->
            <generator class="sequence">
                <param name="sequence">honey_id_seq</param>
            </generator>

            <!--  MySQL generator for a increment field
            <generator class="increment"/>
            -->
        </id>
        <property name="name" column="fooname"/>
        <property name="taste" column="bartaste"/>

    </class>

</hibernate-mapping>

检查您的应用程序服务器是否具有相同的文件，并在日志中警告您使用

http://www.hibernate.org/dtd/

而不是

http://hibernate.sourceforge.net/

我检查你的xml，它是有效的。
