但是，每当我尝试访问测试端点时，它都会崩溃。每当我尝试访问基本的GET端点时，它似乎都会崩溃。

任何人都会遇到Heroku这个问题吗？

TIA

我猜它是由端口引起的。我在我的proc文件中写这个并且工作

web: java -jar -Dserver.port=$PORT target/<application_deployed_name.jar>

我希望它有所帮助

Spring文档支持这种简单的方法： Spring Boot Reference Guide

答案 1 :(得分：5)

我设法通过将Heroku Assigned PORT设置为我的应用程序的默认端口来解决此问题。

我没有使用自己的PORT，而是使用System.getenv（“PORT”）强制我的应用程序使用Heroku分配的端口。

    @Bean
    public EmbeddedServletContainerCustomizer containerCustomizer() {
        return (container -> {
            container.setContextPath("/nemswiftsvc");
            container.setPort(Integer.valueOf(System.getenv("PORT")));  
        });
    }

答案 2 :(得分：1)

上面的答案有效！只需要一个小的补充（如果声明）让应用程序在本地运行，就像来自像eclipse这样的IDE 

@Bean
public EmbeddedServletContainerCustomizer containerCustomizer() {
    return (container -> {
        container.setContextPath("");
        if(System.getenv("PORT")!=null) {
            container.setPort(Integer.valueOf(System.getenv("PORT"))); 

        }
    });

答案 3 :(得分：1)

晚了一点，但是您也可以简单地将server.port=${PORT:9000}放在application.properties中。在这种情况下，如果找不到端口，则9000是应用程序将默认使用的端口。
