SpringBoot整合Flowable

1. 引入依赖

flowable-spring-boot-starter-basic

<dependency>
    <groupId>org.flowable</groupId>
    <artifactId>flowable-spring-boot-starter-basic</artifactId>
    <version>${flowable.version}</version>
</dependency>

2. 配置文件

application.properties 主要配置数据源

server.port=10000
server.servlet.context-path=/

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/flowable-springboot?useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai&nullCatalogMeansCurrent=true&useSSL=false
spring.datasource.username=root
spring.datasource.password=123456

# druid config
spring.datasource.druid.initial-size=5
spring.datasource.druid.min-idle=5
spring.datasource.druid.max-active=20
spring.datasource.druid.max-wait=60000
spring.datasource.druid.time-between-eviction-runs-millis=60000
spring.datasource.druid.min-evictable-idle-time-millis=300000
spring.datasource.druid.validation-query=SELECT 1 FROM DUAL
spring.datasource.druid.test-while-idle=true
spring.datasource.druid.test-on-return=false
spring.datasource.druid.test-on-borrow=false
spring.datasource.druid.pool-prepared-statements=true
spring.datasource.druid.max-pool-prepared-statement-per-connection-size=20
spring.datasource.druid.filters=stat,wall,log4j
spring.datasource.druid.connection-properties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

3. 启动查看数据库

启动时，默认会获取 classpath*:/processes/下的所有.bpmn20.xml, .bpmn文件，并完成部署。

查看数据库，表已经自动创建。

4. 设置流程文件位置

设置流程文件位置并在启动时完成部署；

查看 org.flowable.spring.boot.FlowableProperties 完成配置

# 是否开启自动部署流程定义 默认true
flowable.check-process-definitions=true
# 流程定义文件位置
flowable.process-definition-location-prefix=classpath*:/bpmn/
# 流程文件后缀
flowable.process-definition-location-suffixes[0]=**.bpmn20.xml
flowable.process-definition-location-suffixes[1]=**.bpmn

5. 自定义ID生成器

public class CustomIdGenerator implements IdGenerator {
    @Override
    public String getNextId() {
        String uuid = UUID.randomUUID().toString();
        String nextId = "custom:" + uuid.replaceAll("-", "");
        return nextId;
    }
}

@Bean
public IdGenerator idGenerator() {
    return new CustomIdGenerator();
}

6. Flowable配置类

org.flowable.spring.boot.FlowableProperties
org.flowable.spring.boot.process.FlowableProcessProperties
org.flowable.spring.boot.app.FlowableAppProperties
org.flowable.spring.boot.idm.FlowableIdmProperties
org.flowable.spring.boot.FlowableMailProperties
org.flowable.spring.boot.FlowableHttpProperties
