我在Spring MVC和Tomcat上做了简单的应用程序。它还与DB连接。我的应用程序代码在底部。当我在PC上运行它时它工作得很完美但是当我在heroku上部署它时我得到了一个
应用程序错误：

Procfile：
web: sh target/bin/webapp
web: java -cp target/classes/:target/dependency/* com.shop.cond.MainController
目录结构： STRUCTURE
答案 0 :(得分：0)
首先，web:中有两个Procfile条目。如果您需要，请仅使用java -cp。
主要错误是java.lang.NoClassDefFoundError: org/springframework/ui/Model，这通常意味着您在类路径中缺少JAR文件。
您是否已将所有依赖项复制到target/dependency？
通常，您可以在pom.xml中使用以下内容：
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.4</version>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals><goal>copy-dependencies</goal></goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
如果您有该配置，请检查您的Spring依赖项是否未设置为provided。
