Java Maven 3和Hibernate 5的web应用中出现NoClassDefFoundError异常

java hibernate maven jpa

Java Maven 3和Hibernate 5的web应用中出现NoClassDefFoundError异常,java,hibernate,maven,jpa,tomcat8,Java,Hibernate,Maven,Jpa,Tomcat8,我有一个web应用程序，它的后端是Java，与Hibernate、Jackson（用于json解析器）和Jersey一起工作，用于RESTAPI。当我运行服务器（tomcat8）时，我得到一个NoDefClassFoundException，说找不到Persistence类，但很奇怪，因为我有Hibernate 5.2.7依赖项（假设已经包含该类的jpa实现）我不知道为什么我仍然会犯这个错误。如果我查看Maven依赖关系，我会看到org.hibernate.javax.persistence:h

我有一个web应用程序，它的后端是

Java

，与

Hibernate

、

Jackson

（用于json解析器）和

Jersey

一起工作，用于RESTAPI。当我运行服务器（

tomcat8

）时，我得到一个

NoDefClassFoundException

，说找不到

Persistence

类，但很奇怪，因为我有

Hibernate 5.2.7

依赖项（假设已经包含该类的jpa实现）我不知道为什么我仍然会犯这个错误。如果我查看

Maven

依赖关系，我会看到

org.hibernate.javax.persistence:hibernate-jpa-2.1-api

依赖于

javax.persistence

包和

persistence

类。我留给您错误日志和项目树，以便您可以查看Maven下载的依赖项。我正在与IntelliJ 2016.3.3合作，我不知道这在这种情况下是否重要，只是以防万一

任何帮助都会非常棒，非常感谢

如何从intellij清理和构建？？或者我需要从控制台执行此操作？此链接可能会帮助您或google ITI如果我添加hibernate-jpa-2.1-api依赖项，它会显式地创建持久性类，但会在该方法的“createQuery（String qlString，class resultClass）”版本上向我抛出NoSuchMethodError…有什么想法@vels4j？？我真的很感激你提供的帮助你的目标是什么？
