英文:
Acces to Heroku Endpoint - SpringBootApp 503Service Unavailable
问题
以下是翻译好的内容：
我现在在Heroku上部署了一个SpringBoot应用，我想向这个应用发送一些请求，但是我收到了一个503错误消息。
在我的本地环境中，我使用以下URL进行GET请求：http://localhost:8080/suggestions?q=Londo&latitude=43.70011&longitude=-79.4163
而在Heroku上，我使用以下URL：
https://heroku-boot-app-chall.herokuapp.com/suggestions?q=Londo&latitude=43.70011&longitude=-79.4163。我不太确定如何向我部署在Heroku上的应用发送请求，构建已成功。我只是将我的源代码提交到GitHub，我需要在能够发送请求之前执行其他步骤吗？
以下是日志：

谢谢！
英文:
I have a springBoot App deployed in Heroku now, I would like to do some request to this App but I am getting a 503 error message.
In my local I use the next url to do the get request: http://localhost:8080/suggestions?q=Londo&latitude=43.70011&longitude=-79.4163
And in Heroku I'm using the next url:
https://heroku-boot-app-chall.herokuapp.com/suggestions?q=Londo&latitude=43.70011&longitude=-79.4163. I am not pretty sure how can I make request to my App deployed in Heroku the build was success. I just commit my sources in github and Heroku I have to do another step before to be able to do some request?
These are the logs:

最后，我不得不创建一个包含以下信息的 Procfile：
web: java -Dserver.port=$PORT -jar target/backend-coding-challenge-1.0-SNAPSHOT.jar
并且在 pom.xml 中添加以下插件：
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>com.heroku.CityAutocompleteService</mainClass>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>

Finally, I had to create a Procfile with the next info:
web: java -Dserver.port=$PORT -jar target/backend-coding-challenge-1.0-SNAPSHOT.jar
And add the next plugin to the pom.xml:
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>com.heroku.CityAutocompleteService</mainClass>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
