Question

我在maven项目中工作。 Atm我只有实体，映射和配置文件。我试图用junit来测试我的hibernate映射。

我无法找到问题所在。我可以在netbeans中验证xml文件，但是当我运行我的测试时，我收到以下错误。

netbeans中的验证：

XML validation started.

Checking file:/C:/Users/Err/Documents/NetBeansProjects/PinkSocks/src/main/resources/hibernate.cfg.xml...
Referenced entity at "http://localhost:8080/files/hibernate-configuration-4.0.xsd".
XML validation finished.

错误：

hibernate.cfg.xml中：

    <?xml version="1.0" encoding="UTF-8"?>
    <hibernate-configuration

        xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'

            <mapping class="bleh.mihihi.Beverage" file="Beverage.hbm.xml" />
        </session-factory>
    </hibernate-configuration>

Beverage.hbm.xml

EDIT1：

我尝试的事情：

重新输入
使用dtd
将xsd放到其他地方

Answer 1

使用Hibernate 4.x时，你应该使用与3.x相同的DTD：

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

<hibernate-configuration>

    <session-factory>

您可以在此bug report中看到删除弃用警告的位置。 4.2版本的教程也使用了这个，你可以看到here。

Answer 2

您忘了指定DTD。

尝试在xml文件中保留以下代码并告诉我

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

Answer 3

您在hibernate.cfg.xml文件中忘记了DTD

Hibernate SaxParseException
