SpringBoot整合Camunda一

jiezi

5 年前

1、创建一个空 maven 项目
2、引入 camunda 依赖包

<dependencies>
    <dependency>
        <groupId>org.camunda.bpm.springboot</groupId>
        <artifactId>camunda-bpm-spring-boot-starter-webapp</artifactId>
        <version>3.3.1</version>
    </dependency>
    <!-- 这里使用号称光一般快速的数据源 `Hikari`，也是 `SpringBoot 2.x` 后默认使用的数据源 -->
    <dependency>
        <groupId>com.zaxxer</groupId>
        <artifactId>HikariCP</artifactId>
        <version>3.3.1</version>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>
</dependencies>

3、配置数据源

server:
  port: 8080
  tomcat:
    uri-encoding: UTF-8

spring:
  application:
    name: camunda-demo
  datasource:
    username: root
    password: 761341
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/camunda-demo?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=UTC

4、启动项目

可以见到日志中前两行 hikariPool 启动，后面执行 camunda 内置 sql 创建表

HikariPool-1 - Starting...
HikariPool-1 - Start completed.
ENGINE-03016 Performing database operation 'create' on component 'engine' with resource 'org/camunda/bpm/engine/db/create/activiti.mysql.create.engine.sql'

ENGINE-03016 Performing database operation 'create' on component 'decision.engine' with resource 'org/camunda/bpm/engine/db/create/activiti.mysql.create.decision.engine.sql'
ENGINE-03016 Performing database operation 'create' on component 'decision.history' with resource 'org/camunda/bpm/engine/db/create/activiti.mysql.create.decision.history.sql'

5、继续往 application.yml 中添加配置，创建 root 账号

camunda.bpm:
  admin-user:
    id: admin
    password: admin
    firstName: admin
  filter:
    create: All tasks

6、访问 http://localhost:8080

输入我们配置的 root 账号的账号密码，可进入管理后台。
