嗨,

我试着用Hibernate和Maven做一个简单的应用程序。

我创建了hibernate.cfg.xml和映射文件contacts.hbm.xml。

一旦启动，我就会得到一个异常：

看一看DTD。元素property没有属性value。在类似的情况下，当您遇到XML解析错误时，请始终查看DTD或模式描述！

所以就像PSR也说的，改变

代码语言：javascript
复制
<property name="hibernate.connection.provider_class" value="org.hibernate.connection.DriverManagerConnectionProvider"/>

并将value作为子元素移动：

代码语言：javascript
复制
<property name="hibernate.connection.provider_class">org.hibernate.connection.DriverManagerConnectionProvider</property>

而且它是<mapping resources=""...>而不是<mapping resource=""...>。在DTD中，我只能看到resource，而不能看到元素mapping的resources属性。

最后，看起来contacts.hbm.xml存在一个问题。变化

代码语言：javascript
复制
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

至

我认为这是不对的

代码语言：javascript
复制
<property name="hibernate.connection.provider_class" value="org.hibernate.connection.DriverManagerConnectionProvider" />

更改为

代码语言：javascript
复制
 <property name="hibernate.connection.provider_class"> org.hibernate.connection.DriverManagerConnectionProvider</property >

它没有"value“属性
