Question

您好我正在尝试使用mysql配置hibernate。

我使用Maven和IntelliJ来获取我的依赖项。

我的hibernate配置文件是

<?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="connection.url">jdbc:mysql://localhost:3306/test</property>
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.username">root</property>
        <property name="connection.password">SYS</property>
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="transaction.factory_class">org.hibernate.engine.transaction.internal.jdbc.JdbcTransactionFactory</property>
        <mapping resource="Person.hdm.xml"></mapping>
    </session-factory>
</hibernate-configuration>

我有一个映射类Person.hdm.xml

<hibernate-mapping>
    <class name="Person">

        <id name="FirstName"/>

    </class>
</hibernate-mapping>

我得到以下堆栈..

java.lang.NoSuchFieldError：“如果应用程序试图访问或修改对象的指定字段，并且该对象不再具有该字段，则抛出该异常。”

Log4jLogger看起来是罪魁祸首，我注意到它是'org.jboss.logging'..是hibernate期待不同的版本？看起来像环境特定的记录器（即Jboss，app服务器），你在JBoss中运行它吗？
