我得到一个下面Hibernate配置问题 -

以前它是工作的罚款，我能够与Postgres的连接，但现在它不工作。

hibernate.cfg.xml-

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

您可以添加缺少的依赖到Maven

<dependency> 
    <groupId>dom4j</groupId> 
    <artifactId>dom4j</artifactId> 
    <version>1.6.1</version> 
</dependency> 

或者从here下载JAR并包含在你的课程路径中
