结合Tomcat和嵌入式Tomcat JNDI为Grails3配置

Question

我正试图在我的Grails3应用程序中结合一个JNDI配置，它使用嵌入式TomcatServlet容器以及独立的Tomcat容器（由我们的系统团队设置）。

我已经用这个SO问题让我的JNDI配置与嵌入式Tomcat容器一起工作（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时（在构建war文件之后），在Tomcat服务器中使用JNDI配置，我得到以下错误：

为了让它工作，我需要注释掉应用程序中的tomcatFactory（）方法。groovy文件

我的身材。根据链接的SO问题，gradle文件具有以下相关性：

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

有人知道我如何能够组合这两个配置，以便在本地测试时不必注释掉嵌入式Tomcat容器吗？

更新：我们服务器上的Tomcat版本是Tomcat-7.0。54-2.el7_1。noarch。我读过各种各样的博客和页面，建议从嵌入式服务器到Tomcat容器至少应该是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将在WAR文件中包含一个可嵌入的Tomcat版本，因此它是可运行的（请参阅上一节），如果您部署到不同版本的Tomcat，这可能会导致问题。如果您不打算使用嵌入式容器，那么您应该将Tomcat依赖项的范围更改为在build.gradle中部署到生产容器之前提供的：

变化：

runtime“org.apache.tomcat:tomcat dbcp:9.0.0.M1”

到

提供了“org.apache.tomcat:tomcat dbcp:9.0.0.M1”
