问题描述

I have troubles deploying my grails3 application to a tomcat7 server.我在将 grails3 应用程序部署到 tomcat7 服务器时遇到了麻烦。 In the local development environment (bundled tomcat-server) everything works well.在本地开发环境（捆绑的 tomcat-server）中，一切正常。 The code compiles and runs.代码编译并运行。

Then I use grails clean and grails war to create war which I deployed to a tomcat7-instance.然后我使用grails clean和grails war来创建我部署到 tomcat7 实例的战争。 While starting tomcat it crashes with the following error:启动 tomcat 时，它崩溃并出现以下错误：

The problem seems to be that the classloader could not find my spring-security role-domain EwsOhElemeter.Role which is definitely present.问题似乎是类加载器找不到我肯定存在的 spring-security 角色域EwsOhElemeter.Role 。 Also it works in my local environment.它也适用于我的本地环境。

Maybe its a classpath problem or some of the classes do not get compiled into the war file.也许它是一个类路径问题，或者某些类没有被编译到 war 文件中。

Steps I tried: - Changed integrated tomcat-instance from "compile" to "provided" - Cleaned build and grandle folders - A lot of grails clean我尝试过的步骤： - 将集成的 tomcat 实例从“编译”更改为“提供” - 清理构建和grandle 文件夹 - grails clean很多grails clean

I found a solution: It seemed to be a problem with the package name.我找到了一个解决方案：似乎是包名称的问题。 It contained some capital characters.它包含一些大写字符。 Spring security seems to have problems with case sensitive package names. Spring security 似乎对区分大小写的包名有问题。 I converted all of them to lower case and tada: It works!我将它们全部转换为小写和 tada：它有效！

Thanks for the solution感谢您的解决方案
