java - 无法在 hibernate 中找到数据源

Question

我正在尝试从现在的某个时候退出来解决这个问题，我正在使用 OSUSER api 进行简单的用户和组访问。它适用于 JDBC 提供程序(在 OsUser.xml 和 PropertySet.xml 中)

现在，当我尝试将它与 com.opensymphony.user.provider.hibernate.HibernateCredentialsProvider 一起使用时，它显示错误:

控制台似乎无法找到数据源，尽管我已将 hibernate.cfg.xml 添加到类路径中，奇怪的是相同的数据源对 JDBC 连接工作正常。

这是我的hibernate.cfg.xml:

<!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="dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>

        <property name="connection.username">root</property>
        <property name="connection.password">fhl</property>

        <!-- Use the C3P0 connection pool. -->
        <property name="c3p0.min_size">3</property>
        <property name="c3p0.max_size">5</property>

        <property name="cache.use_minimal_puts">false</property>
        <property name="max_fetch_depth">3</property>

        <!-- Print SQL to stdout. -->
        <property name="show_sql">true</property>
        <property name="format_sql">true</property>

        <!-- Drop and then re-create schema on SessionFactory build, for testing. -->
        <property name="hbm2ddl.auto">create</property>

        <!-- Bind the getCurrentSession() method to the thread. -->
        <property name="current_session_context_class">thread</property>

        <!-- Hibernate XML mapping files -->
        <mapping resource="org/MyClass.hbm.xml" />

        <!-- Hibernate Annotations (and package-info.java) <mapping package="org.mypackage"/> 
            <mapping class="org.MyClass/> -->
    </session-factory>
</hibernate-configuration>

请告诉我我缺少什么，因为我是 hibernate 新手......

提前致谢。

Answer 1

终于解决了这个问题，之前

    <property name="connection.datasource">fhlabs</property>

之后

    <property name="connection.datasource">java:comp/env/fhlabs</property>

现在工作正常。
