Question

我关注此指南 - https://camunda.github.io/camunda-bpm-spring-boot-starter/docs/2.2.0/index.html 并创建我自己的新springboot-camunda项目。

我想将之前创建的war文件部署到Camunda-ee本地服务器。我希望在Camunda驾驶舱看到这个。但它不在那里。我非常感谢有关如何将Camunda springboot webapp项目部署到Camunda服务器的任何有用信息。这是我的代码：

@SpringBootApplication
@EnableProcessApplication
public class SlognSpringBootProcessApplication {

    public static void main(String[] args) {
        SpringApplication springApplication = new SpringApplication(SlognSpringBootProcessApplication.class);

        springApplication.run(args);
    }
}

processes.xml：

<?xml version="1.0" encoding="UTF-8"?>
<process-application
        xmlns="http://www.camunda.org/schema/1.0/ProcessApplication"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

    <process-archive>
        <process-engine>default</process-engine>
        <properties>
            <property name="isDeleteUponUndeploy">true</property>
            <property name="isScanForProcessDefinitions">true</property>
        </properties>
    </process-archive>

</process-application>

application.properties：

camunda.bpm.auto-deployment-enabled=true

的pom.xml：

Answer 1

首先注意：使用@EnableProcessApplication时，会禁用自动部署，因此您可以省略此设置：“camunda.bpm.auto-deployment-enabled = true”。

对于主要问题：您正在尝试的是将Spring启动应用程序打包为war并在应用程序服务器上部署。

结帐https://github.com/camunda/camunda-bpm-spring-boot-starter/tree/master/examples/example-war，我猜你忘了扩展初始化程序：

@SpringBootApplication
@EnableProcessApplication
public class SlognSpringBootProcessApplication extends SpringBootServletInitializer {...}

所以引擎是在战争部署时创建的。

Answer 2

我知道你怎么了。

您正在尝试创建war文件并将其部署在共享的camunda引擎上。所以让我告诉您，这不是您的正确做法。 Camunda入门罐在侧面装有tomcat。并且生成的战争文件将使用您已经通过启动程序jar提供的camunda引擎。

要解决此问题，您需要使用Spring Boot和Spring Framework的混合版本。在您的项目中使用spring boot，在camunda引擎中使用spring framework。您需要使用作为上下文的共享引擎运行时。在这里，您可以看到pom示例和必须提及的类。 http://javaint4bytes.blogspot.com/2019/11/camunda-spring-boot-with-shared-engine.html

Camunda springboot项目未部署在Camunda-ee tomcat服务器上
