Question

我正在使用我的应用程序整天运行grails test run-app，这很好。我键入“grails prod war”来获取战争，并将其转储到我的tomcat安装的webapps文件夹中。现在我得到这样的信息：

造成这种情况的原因是什么？我肯定在我的WAR中有docx4j jar，它也存在于web-inf lib文件夹中。

Answer 1

您获得的是java.lang.NoClassDefFoundError，而不是java.lang.ClassNotFoundException。正在加载该类，但它所依赖的类（直接或间接通过另一个类）不存在。您很可能错过了docx4j作为依赖项所需的jar。

Answer 2

确保您拥有正确版本的docx4j，并且您的类路径中绝对没有其他版本的docx4j，可能有一个版本的lib没有实现“Content”类。

我的grails项目中的jar在部署到tomcat 5.5时没有被拾取
