Question

我对Maven和＆amp; Heroku的。我试图了解RESTful Web服务。所以我在JAX-RS＆amp; amp;创建了一个示例Web应用程序。在Heroku中部署它。当我在我的本地Tomcat 8上运行它时，示例Web应用程序运行完美。但是，当我尝试在Heroku上打开相同的Web应用程序时，它会给我应用程序错误。

这是我在localhost:8080

上运行时获得的结果

但是当我尝试在this运行相同的网络应用时，它会给我以下错误

我很确定我错过了什么，但我无法弄清楚是什么。

以下是我的 index.jsp

<html>
<body>
    <h2>Jersey RESTful Web Application!</h2>
    <p><a href="webapi/myresource">Jersey resource</a>
    <p>Visit <a href="http://jersey.java.net">Project Jersey website</a>
    for more information on Jersey!
</body>

Procfile

web: java $JAVA_OPTS -cp target/classes:target/dependency/* MyResource

感谢您的时间！

Answer 1

我自己找到了解决方案。我忘了将$('.example-class').click(function(e){ if ((e.target.tagName.toLowerCase()) == 'a') { console.log('You clicked an A element.'); } else { // DIV, we assume in this example console.log('You clicked a DIV element.'); } });插件添加到webapp-runner

这是插件
