SpringBoot集成Flowable工作流
Spring Boot 整合 Flowable 工作流的方法主要包括以下几个步骤:
- 在 Spring Boot 项目的
pom.xml
文件中添加 Flowable 相关依赖。 - 配置数据源和 Flowable 相关配置。
- 创建配置类,初始化流程引擎。
- 使用 Flowable API 进行工作流的开发。
以下是一个简单的例子:
pom.xml 添加依赖
<dependencies>
<!-- Flowable 工作流引擎 -->
<dependency>
<groupId>org.flowable</groupId>
<artifactId>flowable-spring-boot-starter</artifactId>
<version>6.7.2</version>
</dependency>
<!-- 其他依赖 -->
</dependencies>
application.properties 或 application.yml 配置数据源和Flowable
# 数据源配置
spring.datasource.url=jdbc:mysql://localhost:3306/flowable?useSSL=false
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
# Flowable 配置
spring.flowable.database-schema-update=true
spring.flowable.async-executor-enabled=false
spring.flowable.job-executor-enabled=false
FlowableConfig 配置类
import org.flowable.spring.SpringProcessEngineConfiguration;
import org.flowable.spring.boot.EngineConfigurationConfigurer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.Resource;
import org.springframework.core.io.ResourceLoader;
@Configuration
public class FlowableConfig implements EngineConfigurationConfigurer<SpringProcessEngineConfiguration> {
@Bean
public Resource[] deploymentResources() {
// 返回bpmn和png部署文件资源
}
@Override
public void configure(SpringProcessEngineConfiguration engineConfiguration) {
// 可以在这里进行自定义配置
}
}
使用 Flowable API 进行工作流部署和操作
import org.flowable.engine.RepositoryService;
import org.flowable.engine.RuntimeService;
import org.flowable.engine.repository.Deployment;
import org.flowable.engine.runtime.ProcessInstance;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class WorkflowService {
@Autowired
private RepositoryService repositoryService;
@Autowired
private RuntimeService runtimeService;
public void deployProcess() {
Deployment deployment = repositoryService.createDeployment()
.addResourcesFromResourceIds("bpmnFileResourceId", "pngFileResourceId")
.deploy();
System.out.println("流程定义ID:" + deployment.getId());
}
public void startPr
