Java工作流Activity

Java 端的开源工作流

https://www.activiti.org/documentation

开始使用

https://www.activiti.org/quick-start

使用Activiti将业务流程管理（BPM）嵌入到您的应用程序中的简便性

标准的业务流程建模表示法（BPMN）逻辑

• Activiti（org.activiti）– Activiti的BPM引擎
• 数据库（com.h2database）– H2数据库
• 日志（org.slf4j）– Java的简单日志外观

使用的依赖

        <dependency>
            <groupId>org.activiti</groupId>
            <artifactId>activiti-engine</artifactId>
            <version>6.0.0</version>
        </dependency>

始终保持最新的项目包，能够编译通过

mvn clean package

日志配置 log4j 记录

log4j.rootLogger=DEBUG, ACT

log4j.appender.ACT=org.apache.log4j.ConsoleAppender
log4j.appender.ACT.layout=org.apache.log4j.PatternLayout
log4j.appender.ACT.layout.ConversionPattern= %d{hh:mm:ss,SSS} [%t] %-5p %c %x - %m%n

编译成 可执行的 jar 

执行：

java -jar activity-start-1.0-SNAPSHOT-jar-with-dependencies.jar

加载模型并执行

// 加载提供的BPMN模型并将其部署到Activiti Process Engine。
RepositoryService repositoryService = processEngine.getRepositoryService();
Deployment deployment = repositoryService.createDeployment()
        .addClasspathResource("onboarding.bpmn20.xml").deploy();

// 检索已部署的模型，证明它在Activiti存储库中。
ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery()
        .deploymentId(deployment.getId()).singleResult();
System.out.println(
        "Found process definition ["
                + processDefinition.getName() + "] with id ["
                + processDefinition.getId() + "]");

01:52:12,423 [main] DEBUG org.activiti.engine.impl.interceptor.LogInterceptor  - 

Found process definition [Onboarding] with id [onboarding:1:4]

完成了 变量 的输入 输出 效果展示。

renren-fast 集成 activity

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springProcessEngineConfiguration' defined in class path resource 

【解决办法】

解决：activity默认校验resources下的processes文件夹里的流程文件,可以手动创建processes文件夹并放入设计好的流程文件或者在配置文件中配置不校验：

spring.activiti.check-process-definitions=false
