Camunda，不会部署到 Tomcat答案

【问题标题】：Camunda, Wont deploy to TomcatCamunda，不会部署到 Tomcat
【发布时间】：2020-02-09 21:49:56
【问题描述】：

我正在尝试创建一个完整的 Camunda 实例（驾驶舱、andmin、tasklist、engine-rest，...）。

我已经使用他们的 archtype 创建了一个项目，并使用 maven springboot:run 成功运行了它

但是在尝试将项目部署到 Tomcat 服务器时。我面临项目无法访问的问题。

我有以下 pom.xml

我有以下应用程序类

package com.myapplication.camunda;

import org.camunda.bpm.spring.boot.starter.annotation.EnableProcessApplication;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@EnableProcessApplication("camunda-all")
@ComponentScan("com.myapplication.camunda")
@ComponentScan("com.springboot.camunda")
public class CamundaApplication extends SpringBootServletInitializer {

    public static void main(String... args) {
      SpringApplication.run(CamundaApplication.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
      return application.sources(CamundaApplication.class);
    }
}

以下application.yaml

spring.datasource:
  url: jdbc:postgresql://localhost:5432/camunda_db?autoReconnect=true

  username: postgres
  password: postgres
  driver-class-name: org.postgresql.Driver
spring.h2.console.enabled: true
camunda.bpm:
  admin-user:
    id: demo
    password: demo
    firstName: Demo
  filter:
    create: All tasks
server.port: 8080
server:
  servlet:
    context-path: /camunda-all

我的 main/resources/webapp 目录是空的。

非常感谢任何帮助。

标签： spring-boot tomcat camunda

【解决方案1】：

创建了空的 maven 项目
添加了您在上面发布的文件
为我的 postgres 调整了数据库设置
cmd: mvn spring-boot:run

可通过http://localhost:8080/camunda-all 访问门户

然后为外部 tomcat 部署调整 POM（也升级版本和清理）。

此处更新结果： https://github.com/rob2universe/stackoverflow58356978

【讨论】：

感谢您的帮助。但是该项目已经在独立设置中运行。我想将项目中的战争文件部署到 Tomcat 9 服务器，这是我的问题。谢谢。
进行了更改。请立即查看

【解决方案2】：

在 camunda 应用服务器中部署你的战争有几件事要做。

在 pom.xml 文件中添加所需的依赖项

<dependency>
     <groupId>org.camunda.bpm</groupId>
     <artifactId>camunda-engine</artifactId>
     <version>7.13.0</version>
     <scope>provided</scope>
</dependency>

将@EnableProcessApplication("camunda-all") 替换为@ProcessApplication("camunda-all")
使用 ServletProcessApplication 扩展您的主类，而不是使用 SpringBootServletInitializer。
在资源/META-INF 文件夹内的 process.xml 文件中添加了您的 BPMN 文件。


<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>
    <resource>invoice.v2.bpmn</resource>
    <resource>invoiceBusinessDecisions.dmn</resource>
    <properties>
      <property name="isDeleteUponUndeploy">false</property>
      <property name="isScanForProcessDefinitions">false</property>
    </properties>
  </process-archive>

</process-application>
