java - 无法将 camunda-bom 添加到 springboot 项目

Question

我正在尝试使用 springboot 创建一个 camunda 应用程序，但我需要使用 Spin Json Node，当我将依赖项添加到 pom.xml 时，当我将项目作为 java 应用程序运行时，它会给我这个错误:

如果我从 pom.xml 中的 dependencyManagement 中删除 camunda-bom，一切都会正常，但我无法使用 spin json 节点之类的东西。

我在 github 中创建了一个简单的项目，但出现此错误:https://github.com/jradesenv/camunda-springboot

Answer 1

您在 GitHub 上提供的项目在我这边运行得非常好并且按预期运行。您切断了部分堆栈跟踪，因此我看不到根本原因。有什么东西阻止 Tomcat 启动 - 可能是一个已经使用的端口？

PS:我们昨天发布了即将推出的 Spring Boot 原型(prototype)的预览:https://github.com/camunda/camunda-archetypes/tree/master/camunda-archetype-spring-boot/ - 也可能是一个很好的起点。

仅供引用我的控制台(我刚刚提取代码并运行它):
