结合Grails的Tomcat和嵌入式Tomcat JNDI配置3

Question

我试图在我的Grails 3应用程序中结合使用JNDI配置，该应用程序利用嵌入式Tomcat Servlet容器以及独立的tomcat容器（由我们的系统团队设置）。

我已经使用这个SO问题来使我的JNDI配置与Embedded Tomcat容器一起使用（用于localhost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（构建war文件之后），并且在Tomcat服务器中使用JNDI配置时，出现以下错误：

为了使其正常工作，我需要在Application.groovy文件中注释掉tomcatFactory()方法。

根据链接的SO问题，我的build.gradle文件具有以下依赖性：

runtime "org.apache.tomcat:tomcat-dbcp:9.0.0.M1"

有谁知道我如何能够将这两种配置组合在一起，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版本是tomcat-7.0.54-2.el7_1.noarch 。 我阅读过许多博客和页面，建议从嵌入式服务器到Tomcat容器的最低发行量为7.0.55。 这可能是版本不足的问题吗？

Answer 1

基于文档 ：

请注意，默认情况下，Grails会在WAR文件中包含Tomcat的可嵌入版本，以便它可以运行（请参阅上一节），如果您部署到其他版本的Tomcat，则可能会导致问题。 如果您不打算使用嵌入式容器，则应在将其部署到build.gradle中的生产容器之前，将Tomcat依赖项的范围更改为提供的：

更改：

runtime "org.apache.tomcat:tomcat-dbcp:9.0.0.M1"

至

provided "org.apache.tomcat:tomcat-dbcp:9.0.0.M1"
