記camunda入門使用-1（基於spring boot）

准備工作

話不多說，之前使用過Activiti搭建工作流，但在這邊沒有記錄完全，正好最近有一個camunda的項目，就決定同時記錄一下項目的開發過程，以便之后再用到。

spring boot版本為2.2.6.RELEASE，camunda基於camunda-bpm-spring-boot-starter，版本為3.4.2，這邊分了多個module，自己使用可以自行合並

配置文件

以下為yaml文件配置

  bpm:
    #登錄用戶賬號密碼
    admin-user:
      id: admin
      password: admin
      firstName: admin
    filter:
      create: All tasks
    job-execution:

#mysql 數據庫配置 camunda會在啟動時自動在此數據庫中新建表結構
spring:
  application:
    name: camunda-demo

    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/camunda?serverTimezone=UTC
    username: root
    password: root
    type: com.alibaba.druid.pool.DruidDataSource

 

目錄配置

 需要在工程目錄的resources下，新建META-INF文件夾，里面新建一個processes.xml文件，沒有特殊需求的話默認為空即可。

 

常用方法（20201225）

獲取某個任務的待處理人（組）

        List<IdentityLink> identityLinks = taskService.getIdentityLinksForTask(taskId);
