我仔细查看了我的配置文件，但我现在不知道是什么问题.. 这些是我的配置文件的顺序

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

和休眠类实用程序。

很抱歉我使用图像而不是代码，但我遇到了缩进问题...

我刚刚解决了一个

failed.org.hibernate.internal.util.config.ConfigurationException: Unable to 
perform unmarshalling at line number 0 and column 0 in RESOURCE  
hibernate.cfg.xml.

构建我自己的应用程序时出错。

解决方案实际上非常简单，即我的 pom.xml 文件中缺少依赖项。我只有一个：

...
<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.1</version>
</dependency>
...

添加以下三个解决了问题：

<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.2.11</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
<version>2.3.2</version>
</dependency>
<dependency>
  <groupId>javax.activation</groupId>
  <artifactId>activation</artifactId>
  <version>1.1.1</version>
</dependency>

我希望这会对某人有所帮助。

请确保您的“hibernate.cfg.xml”文件存在于您项目的“src”文件夹中。
