This article mainly introduces how to integrate springboot camunda, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

1. Description

Camunda uses the workflow engine opened by Java. Springboot 2.2.6.release + camunda 3.4.2 is used here

2. Configure the actual combat

Using the camunda process engine, web interface, and Rest service interface, the corresponding dependencies are as follows:

Process engine: camunda-bpm-spring-boot-starter

Rest service interface: camunda-bpm-spring-boot-starter-rest

Web interface module: camunda-bpm-spring-boot-starter-webapp

If you are just using a process engine, you only need to introduce camunda-bpm-spring-boot-starter.

(1) pom.xml file configuration

3.4.2 org.camunda.bpm.springboot camunda-bpm-spring-boot-starter-webapp ${camunda.version} org.camunda.bpm.springboot camunda-bpm-spring-boot-starter-rest ${camunda.version} org.camunda.bpm.springboot camunda-bpm-spring-boot-starter ${camunda.version}

(2) yml file configuration

Camunda: bpm: # configure account password to access Camunda's built-in management interface admin-user: id: admin password: admin first-name: admin filter: create: All tasks # specify database type # database: # type: mysql # prohibit automatic deployment of bpmn files under resources auto-deployment-enabled: false # prohibit index from jumping to Camunda's own management interface Default true# webapp:# index-redirect-enabled: false

(3) start the project

Browser input: http://localhost:8050/family-admin (the tomcat-context path of the project) can view the relevant tasklist in the current workflow, etc.

The first time you start, the Mysql database automatically generates Camunda-related database tables

3. Generate database table description

ACT_RE_*:RE stands for saving repository. Tables with prefixes contain "static" information, such as process definitions and process resources (images, rules, and so on).

ACT_RU_*:RU stands for runtime. These are runtime tables that contain run-time data for process instances, user tasks, variables, jobs, and so on. The engine stores runtime data only during the execution of the process instance and deletes the record at the end of the process instance. This makes the runtime table small and fast.

ACT_ID_*:ID stands for identity. These tables contain identity information, such as users, groups, and so on.

ACT_HI_*:HI stands for history. These are tables that contain historical data, such as past process instances, variables, tasks, and so on.

ACT_GE_*:GE represents general general data and is used in various use cases
