Hibernate：必须声明元素类型“hibernate-configuration”。无需迁移

问题描述 投票：0回答：4

我正在使用maven来集成我的项目。我收到常见的“必须声明元素类型“hibernate-configuration””。问题虽然我没有对我的项目的休眠部分进行任何更改。它自己停止工作了。

异常

我的 hibernate.cdf.xml 文件：

<?xml version = "1.0" encoding = "utf-8"?>
<!DOCTYPE hibernate-configuration SYSTEM 
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
<session-factory>
<property     name="hibernate.current_session_context_class">thread</property>
<property name="hibernate.enable_lazy_load_no_trans">true</property>
</session-factory>
</hibernate-configuration>

编程配置：

@EnableTransactionManagement
@Configuration
@ImportResource(value = {"classpath:hibernate.cdf.xml"})
public class HibernateConfiguration {

@Bean
public LocalSessionFactoryBean sessionFactory() {
//System.out.println("HibernateConfiguration : SESSION FACTORY LOADED");
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
sessionFactory.setDataSource(dataSource());
sessionFactory.setPackagesToScan(new String [] {"Entities"});
sessionFactory.setHibernateProperties(hibernateProperties());

return sessionFactory;
}

@Bean
public DataSource dataSource() {
//System.out.println("HibernateConfiguration : DataSource LOADED");
BasicDataSource dataSource = new BasicDataSource();
dataSource.setUrl("jdbc:mysql://localhost/sakila");
dataSource.setUsername("username");
dataSource.setPassword("password");
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
return dataSource;
}

@Bean
public PlatformTransactionManager hibernateTransactionManager            (SessionFactory sessionFactory) {

//System.out.println("Obtained sessionFactory: "+sessionFactory);
HibernateTransactionManager transactionManager = new         HibernateTransactionManager();
transactionManager.setSessionFactory(sessionFactory);
return transactionManager;
}

private final Properties hibernateProperties() {

Properties hibernateProperties = new Properties();

hibernateProperties.setProperty      ("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");

return hibernateProperties;

}

}

我没有对代码进行版本控制，并对其进行了一段时间（5 个多月）的处理，错误的发生并不是无缘无故的。您能提出修改建议吗？

在映射中，我替换为：

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"classpath://org/hibernate/hibernate-mapping-3.0.dtd">

在配置中，我替换为：

<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"classpath://org/hibernate/hibernate-configuration-3.0.dtd">

http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd是很好的网址，但从昨天开始就非常不稳定:'(

“重定向 301”到 https://hibernate.org 似乎导致了这个问题。并且直接在 xml 中使用 https 也不起作用。

小心，旧的 tomcat（6 或之前）无法识别协议“classpath://”。

我找到了解决方案。由于我主要使用编程配置，因此我删除了 @ImportResource(value = {"classpath:hibernate.cdf.xml"}) 注释，以便不会使用 hibernate.cdf.xml。然后我尝试使用编程配置来设置以前在 xml 中看到的属性。

这个：

<property     name="hibernate.current_session_context_class">thread</property>
<property name="hibernate.enable_lazy_load_no_trans">true</property>

可以表示为：

hibernateProperties.setProperty  ("org.hibernate.context.internal.ThreadLocalSessionContext", "thread");
hibernateProperties.setProperty("hibernate.enable_lazy_load_no_trans", "true");

如果您认为合适请点赞。

DTD 文件位于两个 HTTP 重定向 (301) 后面，而读取 XML 并使用 DTD 进行验证的 Java 的 InputStream 对此不能很好地工作。将 DTD 替换为：

https://hibernate.org/dtd/hibernate-configuration-3.0.dtd

这样就可以直接链接到它了

在将应用程序迁移到使用 hibernate 6(hibernate-core:6.4.4.Final) 时，我遇到了同样的问题。 我已按照说明操作并放置了此网址 -->

“https：//www.hibernate.org/dtd/hibernate-mapping-3.0.dtd” 替换较早的 “https：//hibernate.sourceforge.net/hibernate-mapping-3.0.dtd”

警告消失了，工作正常。
