Question

我正在尝试将Grails 3应用程序部署到Elastic Beanstalk上的Tomcat 8实例，我尝试了一些我在Google和Stack Exchange上发现的内容，包括更改“org.springframework.boot：spring” -boot-starter-tomcat“依赖从”编译“到”提供“，这是行不通的。 Elastic Beanstalk将接受war文件，但只显示一个空白页面。

我打开了Grails生成的war文件，发现在WEB-INF下的基目录或web.xml文件中没有index.jsp文件。这两个都存在于我使用Maven web-app原型制作的简单war文件中，它有效，所以我有两个问题：

1）是否还有其他人从最新版本的Grails到Tomcat 8部署了应用程序？特别是在Elastic Beanstalk上，特别是最近？我从谷歌搜索中找到的大多数答案都是旧的，所以我想也许新版本的内容已经发生了变化。

2）在打开WAR文件并加载它时，看到Tomcat 8进行的过程的最佳参考是什么？我想如果我能深入研究这个过程，我可以找出丢失的部分在哪里。

@John Stanford，我发现同样的问题我的grails版本是3.2.3

我在本地测试了部署到我的tomcat8，发现我的数据源配置导致了这个问题，我的grails app只是虚拟app，不需要数据库连接，

log /var/lib/tomcat8/logs/catalina.2017-xx-xx.log显示如下

所以我注释掉了application.yml

的production.dataSource.url

environments:
    development:
        dataSource:
            dbCreate: create-drop
            url: jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE
    test:
        dataSource:
            dbCreate: update
            url: jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE
    production:
        grails:
            serverURL: http://xxx-evn-yyy-zzzz-aws-zone-2.elasticbeanstalk.com
        dataSource:
            dbCreate: none
            #url: jdbc:h2:./prodDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE
            properties:
                jmxEnabled: true
                initialSize: 5
                maxActive: 50
                minIdle: 5
                maxIdle: 25
                maxWait: 10000

最后部署到AWS Beanstalk并且它可以工作！
