【问题讨论】：

向我们展示您的代码。看起来像不兼容的依赖项。
Suraj，请看下面我的评论。
请将其添加为您的问题的编辑。那不是 cmets 部分，您已经发布了答案。将其删除并将其添加到您的问题中。
再次感谢您让我知道这一点。我已按照建议更新了我的问题。
您可以尝试使用春季版本 4.2.5.RELEASE 吗？此外，检查您的类路径并确保它选择了正确的弹簧版本。检查您是否有任何重复的罐子。

标签： java spring heroku model-view-controller deployment

【解决方案1】：

java.lang.NoSuchMethodError: org.springframework.util.ReflectionUtils.clearCache()V

这可能意味着您有不兼容的依赖项。

你可以试试这些：

检查您的 pom 以确保您拥有所有兼容的依赖项。
检查您的类路径并验证是否引用了正确的 jar。
检查您的类路径是否有任何重复的 jar。

【解决方案2】：

我在 heroku 中遇到了同样的问题。该问题与我的代码或应用程序相关的配置文件（包括 pom.xml）无关。因为我的应用程序工作正常，突然间我看到容器崩溃，当我尝试启动它时，我不断收到这个线程中描述的错误。大约 24 小时后，tomcat 重新开始自己工作，而我没有更改代码或 pom.xml 中的任何内容。所以，虽然我不知道问题的根本原因，但我知道这不是我做过的事情。这与环境有关。
