無法創建sessionFactory object.org.hibernate.MappingException：無效的配置

爲什麼我嘗試執行main時出現「無法創建sessionFactory object.org.hibernate.MappingException：無效配置」？我正在使用Hibernate 4.2.11.Final和PostGreSQL DB。這是我的hibernate.cfg.xml：無法創建sessionFactory object.org.hibernate.MappingException：無效的配置

<?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.dialect">org.hibernate.dialect.PostgreSQLDialect</property>

     <property name="hibernate.connection.username">postgres</property> 
     <property name="hibernate.connection.password">postgres</property> 
     <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/ProgettoPersonaleDB</property> 
     <property name="connection_pool_size">1</property> 
     <property name="hbm2ddl.auto">create</property> 
     <property name="show_sql">true</property> 
     <property name="hibernate.current_session_context_class">thread</property> 

     <!-- Drop and re-create the database schema on startup --> 
     <property name="hbm2ddl.auto">update</property> 
     <!-- <mapping class="org.javabrains.sanjaya.dto.UserDetails" /> --> 
     <mapping resource="Players.hbm.xml" />

     <mapping 
      class="ProgettoPersonale/src/main/java/ProgettoPersonale/ProgettoPersonale/Users.java" /> 
     /
     <mapping 
      class="ProgettoPersonale/src/main/java/ProgettoPersonale/ProgettoPersonale/Players" /> 


     <class-cache class="org.hibernate.auction.Item" usage="read-write"/> 
     <class-cache class="org.hibernate.auction.Bid" usage="read-only"/> 
     <collection-cache collection="org.hibernate.auction.Item.bids" usage="read-write"/> 

    </session-factory> 
</hibernate-configuration>

這是完整的堆棧跟蹤，謝謝！

你有一個額外的/在conf中間：

<hibernate-configuration> 
<session-factory> 
    <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property> 
    <property name="hibernate.connection.driver_class">org.postgresql.Driver</property> 
    <property name="hibernate.connection.username">postgres</property> 
    <property name="hibernate.connection.password">postgres</property> 
    <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/ProgettoPersonaleDB</property> 
    <property name="connection_pool_size">1</property> 
    <property name="hbm2ddl.auto">create</property> 
    <property name="show_sql">true</property> 
    <property name="hibernate.current_session_context_class">thread</property> 

    <!-- Drop and re-create the database schema on startup --> 
    <property name="hbm2ddl.auto">update</property> 
    <!-- <mapping class="org.javabrains.sanjaya.dto.UserDetails" /> -->

    <mapping

    <class-cache class="org.hibernate.auction.Item" usage="read-write"/>

</session-factory>

謝謝！它解決了我的問題。 –

Plz將其標記爲答案 –

看起來好像hibernate.cfg.xml的第26行有一個額外的'/'。刪除並重試。
