camunda-bpm-spring-boot-starter-webapp依赖无法正常工作，嵌入式tomcat失败

时间：2017-08-20 19:02:45

标签： spring maven spring-boot bpm camunda

我正在尝试根据此处给出的示例https://github.com/osteinhauer/camunda-spring-boot-starter-examples创建一个简单的camunda spring boot starter webapp。我的主要应用程序类只有这么简单的代码：

@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">

    <artifactId>parent</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <artifactId>quick-start-webapp</artifactId>

  <dependencies>
  <dependency>
  <groupId>org.camunda.bpm.extension.springboot</groupId>

      <version>${camunda-bpm-spring-boot-starter.version}</version>
    </dependency>
  </dependencies>
</project>

但我的嵌入式tomcat无法启动以下错误：

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，但它没有成功。任何遇到类似问题的人，请帮助或让我们知道正确的依赖关系，以便我可以在springhost上运行camunda webapp。提前谢谢。

@Daniel，在尝试了你的pom.xml后，我遇到了错误。它们与以前的错误不同：

2 个答案:

答案 0 :(得分：5)

只需在pom.xml文件中设置camunda-bpm-spring-boot-starter.version的属性，就像这样。

 <properties>
    <camunda-bpm-spring-boot-starter.version>2.1.2</camunda-bpm-spring-boot-starter.version>
</properties>

然后\再次通过maven导入camunda依赖项，并尝试再次启动应用程序。

这是我在启动camunda时从春季启动中获得的输出
