eclipse - 尝试使用 hibernate 工具生成 pojo 或映射时出现 noclassdeffounderror

Question

我正在尝试从我的数据库生成pojos，但在我的构建中安装了 hibernate tools 3.4 插件和 hibernate 3.6.10 库(它们似乎是全部)的 eclipse indigo 3.7.2 上出现以下错误路径

简短版本:

org.hibernate.console.HibernateConsoleRuntimeException: Received a NoClassDefFoundError, probably the console configuration classpath is incomplete or contains conflicting versions of the same class
Received a NoClassDefFoundError, probably the console configuration classpath is incomplete or contains conflicting versions of the same class
  java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.cfg.reveng.OverrideRepository
  Could not initialize class org.hibernate.cfg.reveng.OverrideRepository
    java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.cfg.reveng.OverrideRepository
    Could not initialize class org.hibernate.cfg.reveng.OverrideRepository

项目构建路径中的我的 jar 是(如果重要的话按顺序排列):

• hibernate-distribution-3.6.10.Final\hibernate3.jar
• hibernate-distribution-3.6.10.Final\lib\required\antlr-2.7.6.jar
• hibernate-distribution-3.6.10.Final\lib\required\commons-collections-3.1.jar
• hibernate-distribution-3.6.10.Final\lib\required\dom4j-1.6.1.jar
• hibernate-distribution-3.6.10.Final\lib\required\javassist-3.12.0.GA.jar
• hibernate-distribution-3.6.10.Final\lib\required\jta-1.1.jar
• hibernate-distribution-3.6.10.Final\lib\required\slf4j-api-1.6.1.jar
• postgresql-9.0-802.jdbc3.jar

我注意到 hibernate 工具插件在其插件文件夹中有一些较旧的 jar 顺便说一句(例如 slf4j 版本为 1.5.8)与此同时，我会尝试伙伴加载

正常堆栈跟踪

我第一次尝试使用代码生成时，我得到了这样的结果:

org.hibernate.console.HibernateConsoleRuntimeException: Received a NoClassDefFoundError, probably the console configuration classpath is incomplete or contains conflicting versions of the same class Received a NoClassDefFoundError, probably the console configuration classpath is incomplete or contains conflicting versions of the same class   java.lang.NoClassDefFoundError: org/objectweb/asm/Type   org/objectweb/asm/Type    
java.lang.NoClassDefFoundError: org/objectweb/asm/Type org/objectweb/asm/Type          
java.lang.ClassNotFoundException: org.objectweb.asm.Type     org.objectweb.asm.Type    

之后我只收到[...]cfg.reveng.OverrideRepository错误。

Answer 1

在经历了几个小时的 NoclassDefFoundError 痛苦之后，我终于找到了解决方案。

重点:hibernate版本的库应该与所选的控制台配置的Hibernate版本相匹配(第3点)。

检查 list :

1. 确保您已下载最新版本的 Hibernate 插件(适合您的 Eclipse 版本)。要获取它，请转到“帮助”->“Eclipse Marketplace”-> 输入:hibernate(Eclipse 版本名称，例如 luna)。选择最新的 JBoss 工具，并选择 Hibernate 和 JBoss Maven Hibernate 配置器来获取最低功能。

2. 从 http://hibernate.org/orm/downloads/ 下载最新的 jar 文件。将这些文件存储在构建路径中的文件夹中。

3. 创建 Hibernate 控制台配置时，请确保从下拉列表中选择最新的 Hibernate 版本。例如就我而言，构建路径中有 Hibernate 4.x jar 文件，因此选择版本 4.3。问题已解决。

尝试从控制台配置的下拉列表中更改 Hibernate 版本。它可能会解决问题。
