我是休眠新手，在处理一个示例时，我遇到了以下错误：

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
Initial SessionFactory creation failed.org.hibernate.HibernateException: Could not parse configuration: /hibernate.cfg.xml

我的 hibernate.cfg.xml 文件是

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

<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>
    <property name="hibernate.connection.password">abc</property>
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
    <property name="show_sql">true</property>
    <mapping resource="com/abc/Test.hbm.xml" />
</session-factory>
</hibernate-configuration>

请提出我在这方面做错了什么？

从hibernate文件夹中的hibernate-mapping-3.0.dtd和hibernate-configuration-3.0.dtd复制dtd （路径：hibernate3/org/hibernate/hibernate-mapping-3.0.dtd和hibernate3/org/hibernate/hibernate-configuration -3.0.dtd) 并将其粘贴到您的 hbm.xml 文件和 cfg.xml 文件中。

you must first, create a file with this name "log4j.properties" (and in a maven project put it in the "resources" folder - subfolder of main folder-) then put this slice of code in pom.xml:

<build>
<resources>
    <resource>
        <directory>src/main/resources</directory>
        <targetPath>${basedir}/target</targetPath>
        <includes>
            <include>log4j.properties</include>
        </includes>
    </resource>
</resources>

原因：org.dom4j.DocumentException：连接被拒绝：连接嵌套异常：连接被拒绝：连接在 org.dom4j.io.SAXReader.read(SAXReader.java:484) 在 org.hibernate.cfg.Configuration.doConfigure(Configuration.爪哇：1481）... 5更多

根据堆栈跟踪的最后几行，我认为问题与您的数据库连接有关。

请检查您要连接的数据库的名称(test)、用户名(root)和密码。(abc)
