为什么将我的Spring Boot APP部署到Heroku后无法启动

Question

我正在尝试通过使用将我的spring boot应用程序上传到Heroku Heroku插件部署。 一旦我运行以下命令：mvn heroku:deploy 构建成功完成，但应用程序不再启动！。

注意：我没有Procfile，因为我正在使用Heroku插件。 使用Procfile时，我仍然会遇到相同的错误！ （这需要将代码推送到git并将代码推送到Heroku，以不同的方式...但是也会遇到相同的错误！。）

我在日志中收到此错误：

Answer 1

尝试将带有heroku / jvm的buildpack部分添加到您的插件配置中：

<buildpacks>
    <buildpack>heroku/jvm</buildpack>
</buildpacks>

然后将server.port设置为$ PORT heroku env变量，如下例所示：

<processTypes>
    <web>java -Dserver.port=$PORT -jar ${full-artifact-name}</web>
</processTypes>

所有更改之后，看起来应该像这样：

<plugin>
    <groupId>com.heroku.sdk</groupId>
    <artifactId>heroku-maven-plugin</artifactId>
    <configuration>
        <appName>springtest2018</appName>
        <includeTarget>false</includeTarget>
        <buildpacks>
            <buildpack>heroku/jvm</buildpack>
        </buildpacks>
        <includes>
            <include>${basedir}/${full-artifact-name}</include>
        </includes>
        <jdkVersion>1.8</jdkVersion>
        <processTypes>
            <web>java -Dserver.port=$PORT -jar ${full-artifact-name}</web>
        </processTypes>
    </configuration>
</plugin>
