如何将Spring启动应用程序项目部署到Heroku

Question

我创建了一个使用JPA存储库并在Json中返回响应的简单服务器.它包括post和get方法.它是一个Spring starter启动应用程序项目,一切都在我的localhost上运行(我使用postman发送和接收json对象).我的问题是当我尝试部署到Heroku时遇到了很多问题.我添加了一个jetty-runner依赖项和插件.我还创建了一个procfile,如下所示:

web: java $JAVA_OPTS -jar target/dependency/jetty-runner.jar --port $PORT target/*.war

最初目标文件夹是空的并且foreman start web说它couldn't find my war file,所以我将以下行添加到pom.xml:

<packaging>war</packaging>

但是项目创建了一个错误,因此我禁用了项目的maven性质,然后再次配置maven,然后在目标文件夹中包含pom.properties和pom.xml.当我尝试部署它时,它说它无法访问目标/依赖项中的jetty jar文件,因为没有这样的文件夹.所以我做了maven install,它安装了丢失的文件夹.现在我得到了错误No transaction manager can be found,所以我为jetty-plus和Atomikos安装了一个依赖项.但现在我仍然得到错误,没有发现事务管理器,并且有一个java.net.bindexception.

我觉得我真的走错了路.我想知道是否有人可以从一开始就告诉我如何将弹簧启动器启动项目部署到heroku.真的很感激任何帮助.

这是我的pom.xml文件:

Answer 1

我发现部署spring boot应用程序与部署spring boot mvc项目有点不同.基本上你不需要jetty-runner依赖或插件,你只需要执行以下步骤:

• 配置mvn项目
• mvn清理并安装
• 将Procfile声明为:web:java $ JAVA_OPTS -Dserver.port = $ PORT -jar target/*.jar
