使用aws子生成器部署的JHipster项目返回http 404错误

时间：2018-08-01 00:50:14

标签： amazon-web-services http-status-code-404 jhipster

关于“ aws子生成器”（不是“ aws-containers子生成器”）的问题。

问题1： 该生成器是否应该更新“ application-prod.yml”？我可以看到运行该子生成器时提供的信息，包括“ .yo-rc.json”中的数据库名称。但是数据库用户名和密码都不存在，也不在“ application-prod.yml”中。

问题2： 我用一些实体生成了一个简单的JHipster项目。在我的PC上本地运行正常。我使用了“ aws子生成器”，一切运行顺利。它创建了Elastic Beanstalk应用程序，一个EC2实例，S3存储桶，RDS数据库，安全组...这是Elastic Beanstalk的事件日志：

但是，现在当我使用Beanstalk应用程序的链接时，它给了我一个 404错误。错过了什么？这是应用程序启动（catalina.out）的日志：

JHipster AWS ElasticBeanstalk选项仅适用于整体，如果在生成项目时选择了该选项，则不会部署JHipster Registry。

如果要禁用JHipster注册表功能，可以在项目中设置两个配置变量。在bootstrap-prod.yml中，设置spring.cloud.config.enabled: false并使用eureka.client.enabled: false在application-prod.yml中禁用Eureka。

关于数据库连接设置，将它们设置为Spring Boot使用的环境变量when creating the ElasticBeanstalk environment，而不是application-prod.yml中的硬编码配置
