Java HIbernate抛出映射异常

嗨

我正在尝试用Hibernate和Maven做一个简单的应用程序。
我已经创建了hibernate.cfg.xml和映射文件contacts.hbm.xml

一旦启动，就会出现异常：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

一旦我改变了

<property name="hibernate.connection.provider_class" value="org.hibernate.connection.DriverManagerConnectionProvider"/>

你确定这是真的吗？因为在DTD中，我只能看到元素“映射”的“资源”属性，而不能看到“资源”属性巴尔萨斯Mária Németh 5分钟前

这对我很有帮助

And finally it looks like there's a problem with contacts.hbm.xml. Change

<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
to

<!DOCTYPE hibernate-mapping PUBLIC 
"-//Hibernate/Hibernate Mapping DTD 3.0//EN" 
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

---

我认为这是不对的

<property name="hibernate.connection.provider_class" value="org.hibernate.connection.DriverManagerConnectionProvider" />

改为

 <property name="hibernate.connection.provider_class"> org.hibernate.connection.DriverManagerConnectionProvider</property >

org.hibernate.connection.driverManager连接提供程序

它没有“value”属性，请查看。 元素

属性

没有属性

值

。 在遇到XML解析错误的类似情况下，请始终查看DTD或模式描述

正如PSR所说，改变

<property name="hibernate.connection.provider_class" value="org.hibernate.connection.DriverManagerConnectionProvider"/>

而且它是

，而不是

。在DTD中，我只能看到元素

映射的
属性
资源
，而不能看到
资源

最后，看起来contacts.hbm.xml有问题。改变

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



到

将此文本添加到hibernate.cfg.xml的顶部


这是一个打字错误：propetry！更改为属性：）尝试理解异常所说的内容：“必须声明元素类型“property”。这意味着没有“财产”这样的属性。然后你会看到它，你会看到打字错误！哦是的，那是一个固定的错误。
