我正在尝试在我的Grails 3应用程序中结合使用嵌入式Tomcat servlet容器的JNDI配置以及独立的tomcat容器（由我们的系统团队设置）。
我使用this SO question让我的JNDI配置使用嵌入式Tomcat容器（用于本地主机开发，例如grails run-app）。
当我在Tomcat独立服务器上运行我的应用程序（在构建war文件之后），在Tomcat服务器中使用JNDI配置时，我收到以下错误：

要使其正常工作，我需要在Application.groovy文件中注释掉tomcatFactory()方法
我的build.gradle文件根据链接的SO问题具有以下依赖关系：
runtime "org.apache.tomcat:tomcat-dbcp:9.0.0.M1"
有没有人知道我如何能够将这两种配置结合起来，以便在本地测试时不必注释掉嵌入式Tomcat容器？
更新：我们服务器上的Tomcat版本为tomcat-7.0.54-2.el7_1.noarch。我已阅读各种博客和页面，建议从嵌入式服务器到Tomcat容器应至少为7.0.55。这可能是版本不足的问题吗？
答案 0 :(得分：0)
基于docs：
请注意，默认情况下，Grails将包含一个可嵌入版本 Tomcat里面的WAR文件使它可以运行（参见前面的内容） 部分），如果部署到不同的版本，这可能会导致问题 汤姆猫如果您不打算使用嵌入式容器，那么您 应该更改之前提供的Tomcat依赖项的范围 在build.gradle中部署到生产容器：
变化：
runtime "org.apache.tomcat:tomcat-dbcp:9.0.0.M1"
到
provided "org.apache.tomcat:tomcat-dbcp:9.0.0.M1"
