Java 在Elastic Beanstalk上将Grails 3应用程序部署到Tomcat 8

java tomcat grails

Java 在Elastic Beanstalk上将Grails 3应用程序部署到Tomcat 8,java,tomcat,grails,Java,Tomcat,Grails,我正在尝试将Grails 3应用程序部署到Elastic Beanstalk上的Tomcat 8实例上，并且我尝试了在Google和Stack Exchange上发现的一些事情，包括将“org.springframework.boot:spring boot starter Tomcat”依赖项从“compile”改为“provided”，但没有成功。Elastic Beanstalk将接受war文件，但随后只显示一个空白页面我打开了Grails生成的war文件，发现基本目录中没有index.

我正在尝试将Grails 3应用程序部署到Elastic Beanstalk上的Tomcat 8实例上，并且我尝试了在Google和Stack Exchange上发现的一些事情，包括将“org.springframework.boot:spring boot starter Tomcat”依赖项从“compile”改为“provided”，但没有成功。Elastic Beanstalk将接受war文件，但随后只显示一个空白页面

我打开了Grails生成的war文件，发现基本目录中没有index.jsp文件，web-INF下也没有web.xml文件。这两个文件都存在于我使用Maven web app原型制作的简单war文件中，可以正常工作，因此我有两个问题：

1）有没有其他人部署过从最新版本的Grails到Tomcat8的应用程序？尤其是弹性豆茎，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，也许新版本改变了一些东西

2）打开WAR文件并加载它时，查看Tomcat8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

我已经在本地测试部署到我的tomcat8，发现我的数据源配置导致了这个问题，我的grails应用只是一个虚拟应用，不需要数据库连接

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

最后部署到AWS Beanstalk，它就可以工作了

我们在EB上部署了不少grails 3，但我们只使用了独立的jar和java EB配置文件。我发现了同样的问题，但不知道如何使其工作，我最终返回到grails 2.3.7，它似乎工作得很好。@JohnStanford，grails v2非常旧，我们应该转向grails 3。0@JonhStanford，我成功部署到AWS tomcat 8.0，grails 3.2.3–我们经常将grails 3部署到EB，但我们只使用独立的jar和java EB配置文件。我发现同样的问题，我不知道如何使它工作，我最终只是恢复到grails 2.3.7，这似乎很好。@JohnStanford，grails v2非常旧，我们应该转到grails 3。0@JonhStanford ,我已成功部署到AWS tomcat 8.0、grails 3.2.3–AWS beanstalk上的tomcat8可能不完全支持H2数据库，因此部署过程中断，结果返回为空白页。AWS beanstalk上的tomcat8可能不完全支持H2数据库，因此部署过程中断，结果返回为空白页
