org.hibernate.MappingNotFoundException：resource：*找不到hbm.xml

时间：2011-08-19 21:25:46

标签： java hibernate jboss

JBoss AS 7.0.1.Final，Hibernate 3.我们有一个MySQL数据源。

我有映射资源指向* hbm.xml文件。我得到部署错误，告诉我'资源：*找不到hbm.xml'，因此实体未正确映射 - 此堆栈跟踪是由于找不到User.hbm.xml，

我们的项目结构类似于

Project
|
|-pom.xml
|
|-src
|  |-main
|     |-java
|     |   |-com... businessobjects
|     |-resources
|     |   |-META-INF
|     |-webapp
|
|-test

我们在src / main / resources / META-INF中有hibernate.cfg.xml，在src / main / java / com / businessobjects /中有各种* .class和* hbm.xml。我们的hibernate.cfg.xml看起来像

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="datasourceName">java:jboss/datasources/MySqlDS</property>
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
        <mapping resource="com/mycompany/myapp/common/businessobjects/User.hbm.xml"/>
        <mapping resource="com/mycompany/myapp/common/businessobjects/Company.hbm.xml"/>
        <mapping resource="com/mycompany/myapp/common/businessobjects/ServerSettings.hbm.xml"/>
        <mapping resource="com/mycompany/myapp/common/businessobjects/Station.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

我尝试过不同的路径指向* hbm.xml文件 - 似乎都没有用。我甚至试过给它提供* hbm.xml文件的绝对路径，这些文件也不起作用。

我也尝试将* hbm.xml复制到与hibernate.cfg.xml相同的目录中 - 这也不起作用，同样的错误。

在我的HibernateUtil类的代码

中，此时看起来错误了 
static {
    try {
        InitialContext ctx = new InitialContext();
        Configuration configuration = new Configuration();
        Properties properties = new Properties();
        sessionFactory = configuration.configure(
            new File("/path/to/src/main/resources/META-INF/hibernate.cfg.xml")
            ).buildSessionFactory();
    } catch (Throwable ex) {
        // Make sure you log the exception, as it might be swallowed
        log.error("Initial SessionFactory lookup failed.", ex);
        throw new ExceptionInInitializerError(ex);
    }
}

任何想法发生了什么？谢谢

2 个答案:

答案 0 :(得分：15)

将映射文件移动到src / main / resources中。只有.java文件属于src / main / java。

编辑：我已经设置了example project on github，展示了如何从hibernate.cfg.xml正确引用XML映射文件。

答案 1 :(得分：3)

Maven只处理来自src / main / java的.java文件，因此将.hbm.xml文件放入树的那一部分意味着它们不会最终出现在war文件中。

Maven从src / main / resources中获取配置文件，并且当您使用路径映射.hbm.xml文件时，他们需要进入src/main/resources/com/mycompany/myapp/common/businessobjects。

希望有所帮助。
