托管 Spring Boot 应用程序答案

【问题标题】：Hosting spring boot app托管 Spring Boot 应用程序
【发布时间】：2018-09-05 20:54:21
【问题描述】：

我无法将我的 Spring Boot 应用程序托管到 Amazon Web Services：Elastic Beanstalk。我确实遵循了一些视频教程和堆栈溢出帖子。还是无奈。我想将我的 war 文件托管到 AWS 并成功运行它。这是我的 pom.xml 和其他东西。它在当地运作良好。但是在部署到 aws 后它不起作用。显示的健康状况很严重。

【问题讨论】：

你至少应该描述你遇到的问题/错误。
停止。混合版本。您正在混合来自 spring boot 1.5.2 和 1.5.9 的 jar，从不混合框架的版本。还要删除 spring-boot-starter-data-jpa 中已经包含的 persistence-api 依赖项，并且您包含的是与您通过`spring-boot-starter-data-jpa 获得的休眠版本不兼容的旧版本。
@M.Deinum 这应该是一个答案。
我更新了 pom.xml 并构建了一个新的 jar。我仍然遇到同样的错误。可能是什么原因？
我做错了什么？

【解决方案1】：

您的pom.xml 中有几处错误

Spring Boot 1.5.2 和 1.5.9 的混合版本（从不混合框架的版本）。
在您使用 JPA 2.0 提供程序时包含 JPA 1.0 API
通常 AWS BeanStalk 希望您的应用程序在端口 5000 上运行。

对于 1，删除冲突依赖项中的 <version> 标记和/或将 Spring Boot 的版本更改为匹配的版本。

删除 JPA 1.0 API。

AWS 希望您的应用程序在端口 5000 上运行。在 application.properties 中将其指定为端口，或者在您的 AWS 环境中指定值为 5000 的环境变量 SERVER_PORT。请参阅Deploying a Spring Boot Application on AWS，尤其是有关如何指定端口的部分。
