目录一、创建SpringBoot工程二、修改Maven配置2.1、修改springboot版本号2.2、引入camunda包三、修改application.yaml配置四、创建Mysql数据库五、启动springbo
使用idea工具,选择File->New->Project,选择Spring Initialzr
输入springboot工程基本信息,本示例命名为“camunda-demo1”, jdk版本选择8
在选择springboot组件的时候,需要选择Spring WEB、JDBC api、mysql Driver 这三个组件。点击下一步完成即可。
由于camunda版本与springboot版本有匹配关系,所以需要修改springboot版本为2.4.3,
官方推荐Camunda7.1.5版本使用Spring Boot 2.4.x版本
具体配置参考camunda官方说明文档:https://docs.camunda.org/manual/7.15/user-guide/spring-boot-integration/version-compatibility/
Pom.xm代码片段:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.4.3</version>
<relativePath/>
</parent>
由于本示例要使用camunda流程引擎、web界面、Rest服务接口,所以需要导入camunda-bpm-spring-boot-starter、camunda-bpm-spring-boot-starter-rest、camunda-bpm-spring-boot-starter-webapp这三个依赖包,如果仅仅是使用流程引擎,只需要引入camunda-bpm-spring-boot-starter就可以了。

打开工程目录下的main\resources\application.yaml文件,如果没有该文件,手动新建一个,录入如下信息。

# https://docs.camunda.org/manual/latest/user-guide/spring-boot-integration/configuration/#camunda-engine-properties
camunda.bpm:

# By default, Spring Boot serves static content from any directories called /static or /public or /resources or
# /META-INF/resources in the classpath. To prevent users from accidentally sharing files, this is disabled here by setting static locations to NULL.
# https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-spring-mvc-static-content
spring.web.resources:
static-locations: NULL
本示例使用的是mysql数据库,数据库URL、username、 password 跟后面数据库信息保存一致。
Camunda默认使用已预先配置好的H2数据库,本示例使用mysql数据库,需要提前创建mysql数据库并导入Camunda建表脚本。
为Camunda平台创建一个数据库模式,名称为camunda715
导入SQL脚本。执行创建所有必需的表和默认索引的SQL DDL脚本。这些脚本可以在configuration/sql/create文件夹中找到。共2个脚本,都需要导入。
导入完成后的表结构,共40张表:
详细配置方法参考:https://lowcode.blog.csdn.net/article/details/117564836
创建springboot工程的时候,自动生成了SpringBootApplication启动类,运行改类启动即可。
package com.example.demo1;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class CamundaDemo1Application {
public static void main(String[] args) {
SpringApplication.run(CamundaDemo1Application.class, args);
}
}
访问:http://localhost:8080,
默认账号密码demo/demo
登录成功后进入camunda控制台
至此,完成了springboot2.4.3+camunda7.15+mysql的集成,后续的如何设计流程、如何启动流程、如何审批流程等操作,跟非springboot方式是一致的,请参考前面的文章。
