java - 将 java web 应用程序部署到 Heroku 时遇到问题

Question

我已经尝试将我的 java 应用程序部署到 Heroku 两天了。我所做的一切都与人们在他们的教程中所做的相同。但有些不对劲。怎么解决？

这里是heroku应用程序日志

我的 pom.xml 中的插件

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <version>2.4</version>
            <executions>
                <execution>

                                <artifactId>jetty-runner</artifactId>

                                <destFileName>jetty-runner.jar</destFileName>
                            </artifactItem>
                        </artifactItems>
                    </configuration>
                </execution>
            </executions>
        </plugin>

和 Procfile

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

Answer 1

到目前为止，我仅在免费帐户中部署了 node.js 应用程序，而没有在 Heroku 上安装插件。我要做的就是采用 heroku 分配的端口，而不是您似乎指定的静态端口

--port 37825

也许这就是问题所在？该错误似乎与端口有关。尝试在 google 上搜索“dynamic port heroku java”
