java - Heroku - 我部署的 Spring MVC 项目不起作用

标签 java spring spring-mvc tomcat heroku

我在 Heroku 上部署我的 Spring MVC 应用程序时遇到问题。我使用的是 Tomcat 8.5。

使用我的应用访问网站后出现一些错误:

javax.servlet.ServletException: Servlet.init() for servlet [dispatcher] threw exception
org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:493)
org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:81)

org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:800)

org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61)
java.lang.Thread.run(Thread.java:748)

在本地服务器上没问题，但是在 Heroku 上部署之后......我为此奋斗了几天......

最佳答案

这是我的服务器日志。
