嗨，我对heroku有点新鲜。该应用程序在本地工作正常，但在heroku上我尝试在控制器上执行休息请求时出现此错误

谢谢Alex。 Spring引导指南有效。为了记录，我的pom.xml文件现在看起来像这样，我甚至不需要proc文件。

我们在您的日志中看到以下内容：

  

使用命令java -Dserver.port=17355 $JAVA_OPTS -jar target/*.jar

启动流程      

...

     

错误：无法访问jarfile target / * .jar

的Heroku-行家-插件

我过去只使用过Procfile，但我发现您也可以使用heroku-maven-plugin来指定启动命令（heroku documentation）。

我认为您需要在<processType>而非heroku-maven-plugin中设置maven-war-plugin代码：

<plugin>
  <groupId>com.heroku.sdk</groupId>
  <artifactId>heroku-maven-plugin</artifactId>
  <configuration>
    <processTypes>
      <web>java $JAVA_OPTS -cp target/classes:target/dependency/* Application</web>
    </processTypes>
  </configuration>
</plugin>

然后，使用此命令进行部署：mvn heroku:deploy -Dheroku.appName=myapp

Spring Boot？

最重要的是，我看到了依赖spring-boot-starter-web。这是一个弹簧启动应用程序？然后，您不应该使用maven-war-plugin而是使用spring-boot-maven-plugin（see this example）构建有效的spring-boot存档

如果你沿着spring-boot路线走下去，你可以把它建成一个Jar并使用以下Procfile（放置在项目的根目录，资本P）：

web: java $JAVA_OPTS -Dserver.port=$PORT -jar target/gs-maven-0.1.0.jar

我认为您可以使用通配符版本，因此您无需不断修改Procfile：

web: java $JAVA_OPTS -Dserver.port=$PORT -jar target/gs-maven-*.jar
