Hibernate无法解析配置：/hibernate.cfg.xml

大家好，我是hibernate的初学者，我知道这里有很多类似的问题。我试图从他们那里解决，但我做不到。我还试图在dtd中将SYSTEM从PUBLIC更改为，但是它不起作用。我用谷歌搜索它，但是到处都显示dtd语句错误。

这是我的配置文件。

<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
   <hibernate-configuration>
<session-factory>
<property name="show_sql">true</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver/property> 
<property name="connection.url">jdbc:mysql://localhost:3306/hibernate</property> 
<property name="username">root</property> 
<property name="password"></property>
<property name="connection.pool_size">1</property>  
<property name="dialect">org.hibernate.dialect.MySQLDialect</property> 
<property name="hbm2ddl.auto">update</property>
<mapping class="org.hibernate.src.userDetails" /> 
</session-factory>
</hibernate-configuration>

我尝试将版本3.0更改为4.0，因为我正在使用hibernate版本4.3.6，但仍无法正常工作。请帮帮我。

这是我的userDetails类。

软件包org.hibernate.src;

@Entity
public class userDetails {
@Id
private int userId ;
private String userName;
@Embedded
private Address address;
public Address getAddress() {
    return address;
}
public void setAddress(Address address) {
    this.address = address;
}
public int getUserId() {
    return userId;
}
public String getUserName() {
    return userName;
}
public void setUserName(String userName) {
    this.userName = userName;
}
public void setUserId(int userId) {
    this.userId = userId;
}
}

这些我已添加到项目中的jar文件：

lib\jpa\hibernate-entitymanager-4.3.6.Final.jar
lib\required\antlr-2.7.7.jar
lib\required\dom4j-1.6.1.jar
lib\required\hibernate-commons-annotations-4.0.5.Final.jar
lib\required\hibernate-core-4.3.6.Final.jar
lib\required\hibernate-jpa-2.1-api-1.0.0.Final.jar
lib\required\jandex-1.1.0.Final.jar
lib\required\javassist-3.18.1-GA.jar
lib\required\jboss-logging-3.1.3.GA.jar
lib\required\jboss-logging-annotations-1.2.0.Beta1.jar
lib\required\jboss-transaction-api_1.2_spec-1.0.0.Final.jar

这是我在运行应用程序时得到的

回答：

我更新了您提到的dtd。非常感谢。

我改变了我的 ****标签。 则表明代码之前空白出现错误。

我解决了它，然后向我显示了可访问的数据库hibernate错误。我什至尝试了很多，即使我没有重新安装我的Wamp服务器。

最后，我创建了一个新数据库并更改了hibernate.cfg.xml文件。

这是我的文件，运行起来很酷…

<?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>
