Hibernate 配置错误 - 获取子项失败并出现 DocumentException

Question

我遇到以下休眠配置问题 -

以前它工作正常，我可以连接到 postgres，但现在它不工作了。

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">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.bytecode.use_reflection_optimizer">false</property>
        <property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
        <property name="hibernate.connection.password">user</property>
        <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/drc</property>
        <property name="hibernate.connection.username">postgres</property>
        <property name="hibernate.default_schema">drcschema</property>
        <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
        <property name="hibernate.search.autoregister_listeners">false</property>
        <property name="hibernate.show_sql">false</property>
        <property name="hibernate.current_session_context_class">thread</property>
        <mapping resource="UserProfile.hbm.xml" />
    </session-factory>
</hibernate-configuration>

您可以将缺少的依赖项添加到您的 Maven 中

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

或者从here下载jar并包含在你的类路径中
