java.net.BindException：无法在Heroku上分配请求的地址

时间：2015-11-21 06:59:48

标签： java sockets heroku spark-java

部署到Heroku后，Spark服务器因此异常而崩溃。我的Procfile如下所示：

web: java $JAVA_OPTS -Dserver=$PORT -jar target/myappname-0.0.1-SNAPSHOT.jar

据我所知，Heroku每次部署应用程序时都会分配一个新的PORT。但是，我从Heroku设置的环境变量中获取PORT值，那么为什么我不能得到这个请求的地址呢？

编辑：将Procfile更正为-Dserver.port = $ PORT后，这些是我的错误日志。

添加--port $ PORT后发生这种情况。基本上，我认为错误没有变化。

2 个答案:

答案 0 :(得分：1)

我发现问题是我在main方法中设置域的IP地址。似乎我们不应该设置它，而只是通过从环境变量$ PORT获取它来设置PORT。

答案 1 :(得分：0)

在Procfile中使用-Dserver.port=$PORT而不是-Dserver=$PORT并部署应用。 如果错误仍然存​​在，请发布您在日志中获得的确切错误。
