camunda-bpm-spring-boot-starter-webapp 依赖项不工作且嵌入 tomcat 失败
camunda-bpm-spring-boot-starter-webapp dependency not working and embedded tomcat failing
我正在尝试根据此处 https://github.com/osteinhauer/camunda-spring-boot-starter-examples 给出的示例创建一个简单的 camunda spring 启动启动器 webapp。我的主应用程序 class 只有这段简单的代码：
@SpringBootApplication
public class StartApp {
public static void main(String[] args) {
// TODO Auto-generated method stub
SpringApplication.run(StartApp.class, args);
}
}
我的 pom.xml 如下所示：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

但是我的嵌入式 tomcat 无法启动并出现以下错误：

看起来只添加 camunda-bpm-spring-boot-starter-webapp 无济于事。需要一些额外的配置。我尝试了很多 maven 依赖项的组合，但没有成功。遇到类似问题的任何人，请帮助或告知正确的依赖项集，以便我可以 运行 本地主机上的 camunda webapp spring 引导。提前致谢。
@Daniel，在尝试了您的 pom.xml 之后，我遇到了以下错误。它们与以前的错误不同：

只需像这样在 pom.xml 文件中为 camunda-bpm-spring-boot-starter.version 设置 属性。
<properties>
<camunda-bpm-spring-boot-starter.version>2.1.2</camunda-bpm-spring-boot-starter.version>
</properties>
然后通过maven再次导入camunda依赖，再次尝试启动应用
这是我在 camunda 启动时从 spring boot 得到的输出

这是我使用的以下 pom.xml，我没有创建任何 bpmn 工作流，只是添加依赖项，但我认为这是创建工作流的良好开端。

仅适用于 Eclipse 用户：在 pom.xml 更改后执行此操作：
你可以看看这个项目，
https://github.com/berndruecker/camunda-spring-boot-amqp-microservice-cloud-example
这里是示例pom.xml供参考，
https://github.com/berndruecker/camunda-spring-boot-amqp-microservice-cloud-example/blob/master/pom.xml
我正在尝试根据此处 https://github.com/osteinhauer/camunda-spring-boot-starter-examples 给出的示例创建一个简单的 camunda spring 启动启动器 webapp。我的主应用程序 class 只有这段简单的代码：
@SpringBootApplication
public class StartApp {
public static void main(String[] args) {
// TODO Auto-generated method stub
SpringApplication.run(StartApp.class, args);
}
}
我的 pom.xml 如下所示：

看起来只添加 camunda-bpm-spring-boot-starter-webapp 无济于事。需要一些额外的配置。我尝试了很多 maven 依赖项的组合，但没有成功。遇到类似问题的任何人，请帮助或告知正确的依赖项集，以便我可以 运行 本地主机上的 camunda webapp spring 引导。提前致谢。
@Daniel，在尝试了您的 pom.xml 之后，我遇到了以下错误。它们与以前的错误不同：

只需像这样在 pom.xml 文件中为 camunda-bpm-spring-boot-starter.version 设置 属性。
<properties>
<camunda-bpm-spring-boot-starter.version>2.1.2</camunda-bpm-spring-boot-starter.version>
</properties>
然后通过maven再次导入camunda依赖，再次尝试启动应用
这是我在 camunda 启动时从 spring boot 得到的输出
