mysql - Hibernate逆向工程错误

Question

我需要一些帮助来解决这个 Hibernate 错误。

我的环境是:

• Eclipse Kepler 服务版本 1
• hibernate 3.6.9
• MySql 5.5

这是我的 hibernate.cfg.xml :

<?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.connection.driver_class">com.mysql.jdbc.Driver</property>
  <property name="hibernate.connection.password">LexoR</property>
  <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/s2me</property>
  <property name="hibernate.connection.username">root</property>
  <property name="hibernate.default_schema">s2me</property>
  <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
 </session-factory>
</hibernate-configuration>

这是 hibernate.reveng.xml:

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >

    <hibernate-reverse-engineering>
      <table-filter match-schema="s2me" match-name=".*"/>
    </hibernate-reverse-engineering>

And the error log whne I try to generate the POJO files:

org.hibernate.console.HibernateConsoleRuntimeException: Received a NoClassDefFoundError, probably the console configuration classpath is incomplete or contains conflicting versions of the same class

我的 Google 搜索没有找到任何帮助。 有什么帮助吗？ 谢谢

您的逆向工程工具已经有 hibernate jar，并且与您的 hibernate jar 冲突。我知道您使用的是哪种逆向工程工具。我猜这是 JBoss 逆向工程工具？最好使用其他替代方案，如 MyEclipse 或 Intellij。这可以用少量资金为您节省大量时间。
