java - Eclipse Hibernate Tools的问题

我正在尝试在Hibernate Tools Eclipse Add-On中使用Hibernate代码生成功能。它给了我以下错误：

org.hibernate.InvalidMappingException：无法从资源Alert.hbm.xml解析映射文档无法从资源Alert.hbm.xml解析映射文档 org.hibernate.MappingException：类在查找属性时找不到警报：alertId 在查找属性时找不到类警报：alertId org.hibernate.MappingException：类在查找属性时找不到警报：alertId 在查找属性时找不到类警报：alertId java.lang.ClassNotFoundException：Alert 警报

它没有找到类Alert.java，但我认为代码生成器（因此名称......）应该为我生成所有的hibernate类。

将eclipse Indigo与Hibernate Tools 3.4.x一起使用。

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>
        <!-- Database connection settings -->
        <property name="connection.driver_class">
            com.mysql.jdbc.Driver
        </property>
        <property name="connection.url">
            jdbc:mysql://localhost:3306/findata?tcpKeepAlive=true
        </property>
        <property name="connection.username">root</property>
        <property name="connection.password">madmax1.</property>

        <property name="connection.pool_size">2</property>
        <property name="show_sql">true</property>
        <property name="dialect">
            org.hibernate.dialect.mysqldialect
        </property>
        <property name="current_session_context_class">thread</property>
        <property name="cache.provider_class">
            org.hibernate.cache.NoCacheProvider
        </property>

        <mapping resource="Alert.hbm.xml" />
        <mapping resource="Entity.hbm.xml" />
        <mapping resource="FactData.hbm.xml" />
        <mapping resource="TimeEvent.hbm.xml" />
        <mapping resource="User.hbm.xml" />
        <mapping resource="AlertTarget.hbm.xml" />
        <mapping resource="LogAlert.hbm.xml" />
    </session-factory>
</hibernate-configuration>

这是Alert.hbm.xml：

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
    <class name="Alert" table="alerts">
        <id name="alertId" column="id">
            <generator class="assigned"/>
        </id>
        <property name="limitValue" column="limit_value" type="decimal" />
        <!-- The unique=true property makes the many-to-one a one-to-one relationship -->
        <many-to-one name="alertEntity" 
            class="Entity" column="entity_id" 
            not-null="true" cascade="all" unique="true"/>
        <set name="alert_targets" table="alerts_alert_targets" cascade="all">
            <key column="alert_id" />
            <many-to-many column="alert_target_id"
                class="AlertTarget" />   
        </set>
   </class>
</hibernate-mapping>
