问题描述
更新:这似乎是由发现和初始化spring bean的顺序引起的.仍然未知服务器为何以不同顺序检测Bean，但为我提供了解决此问题的途径.
UPDATE: This appears to be caused by the order in which spring beans are discovered and initialized. It's still unknown why the servers are detecting the beans in different orders, but gives me path to fix this.
尝试将WAR部署到Tomcat 7(AWS OpsWorks，Ubuntu 12.04，Tomcat 7.0.26，OpenJDK 1.7.0_65)时，我遇到了一个令人费解的问题:
I've run into a puzzling problem trying to deploy a WAR to Tomcat 7 (AWS OpsWorks, Ubuntu 12.04, Tomcat 7.0.26, OpenJDK 1.7.0_65):
在部署WAR之后，由于我正在部署的应用程序中出现spring autowire异常，Tomcat会立即报告初始化上下文的错误. "org.springframework.beans.factory.BeanCreationException:无法自动连线字段...".
After deploying the WAR, Tomcat immediately reports an error initializing the context due to a spring autowire exception in the application I'm deploying. "org.springframework.beans.factory.BeanCreationException: Could not autowire field...".
问题在于，此WAR在我加载过的所有其他服务器上都可以正常工作.我什至已经将解压缩后的webapps应用程序目录(从受影响的服务器中)复制到了具有相同Java和tomcat版本的另一台服务器上，没有任何问题.
The issue is that this WAR works just fine on every other server I've loaded it on. I've even copied the unpacked webapps app directory (from the impacted server) onto another server with the same java and tomcat version with no issues.
重新启动服务器，重新部署和重新启动tomcat似乎没有任何效果.不断给我同样的Spring应用程序错误.
Restarting the server, redeploying, and restarting tomcat doesn't seem to have any effect. Keeps giving me the same spring application error.
关于如何调试此问题的任何建议?具有FINE输出设置的标准Tomcat日志文件除了应用程序的spring错误外，没有提供太多详细信息.
Any recommendations on how to debug this? The standard Tomcat log file with FINE output settings doesn't provide much detail besides the application's spring error.

推荐答案
问题似乎与您的emailTemplateService有关.
Issue seems to be with your emailTemplateService.
关键信息:
No qualifying bean of type [eco.domain.delivery.TemplateRepository]
确保您的自动扫描获取了相关的注释.
Make sure your auto scan is picking up the relevant annotations.
查看您的整个电子邮件服务专线，以确保您具有正确的注释，如果这样做没有帮助，请告诉我.
Check out your whole email service line to ensure you have right annotations, let me know if this doesn't help.
