在Elastic Beanstalk上将Grails 3 App部署到Tomcat 8
在Elastic Beanstalk上将Grails 3 App部署到Tomcat 8
提问于 2017-04-09 04:32:55
我正在尝试将Grails 3应用程序部署到Elastic Beanstalk上的Tomcat8实例上，并尝试了在谷歌和Stack Exchange上找到的一些方法，包括将"org.springframework.boot:spring-boot-starter-tomcat“依赖项从”编译“更改为”提供“，但这并不起作用。Elastic Beanstalk将接受war文件，但随后只会显示一个空白页面。
我打开了Grails生成的war文件，发现在基本目录中没有index.jsp文件，WEB-INF下也没有web.xml文件。这两个都存在于我使用Maven web-app原型创建的一个简单的war文件中，它是有效的，所以我有两个问题：
1)是否有人将最新版本的Grails应用程序部署到Tomcat 8？尤其是在Elastic Beanstalk上，尤其是最近？我在谷歌上找到的大多数答案都是旧的，所以我在想，新版本可能会有一些变化。
2)打开并加载WAR文件时，查看Tomcat 8所经历的过程的最佳参考资料是什么？我想，如果我能更深入地挖掘这个过程，我就能找出缺失的部分在哪里。

@John Stanford，我发现了同样的问题我的grails版本是3.2.3
我在本地测试了deploy to my tomcat8，发现是我数据源配置导致了这个问题，我的grails应用程序只是一个虚拟应用程序，不需要数据库连接，
log /var/lib/tomcat8/logs/catalina.2017-xx-xx.log如下所示

environments:
development:

dataSource:

properties:
jmxEnabled: true
initialSize: 5
maxActive: 50
minIdle: 5
maxIdle: 25
maxWait: 10000最后部署到AWS Beanstalk，它就可以工作了！
