ACTIVITI工作流的集成记录

1、添加jar包

<activiti.version>5.22.0</activiti.version>

<!-- Activiti -->
<dependency>
    <groupId>org.activiti</groupId>
    <artifactId>activiti-engine</artifactId>
    <version>${activiti.version}</version>
</dependency>
<dependency>
    <groupId>org.activiti</groupId>
    <artifactId>activiti-spring</artifactId>
    <version>${activiti.version}</version>
</dependency>
<dependency>
    <groupId>org.activiti</groupId>
    <artifactId>activiti-explorer</artifactId>
    <version>${activiti.version}</version>
    <exclusions>
        <exclusion>
            <artifactId>vaadin</artifactId>
            <groupId>com.vaadin</groupId>
        </exclusion>
        <exclusion>
            <artifactId>dcharts-widget</artifactId>
            <groupId>org.vaadin.addons</groupId>
        </exclusion>
        <exclusion>
            <artifactId>activiti-simple-workflow</artifactId>
            <groupId>org.activiti</groupId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.activiti</groupId>
    <artifactId>activiti-modeler</artifactId>
    <version>${activiti.version}</version>

    <groupId>org.activiti</groupId>
    <artifactId>activiti-diagram-rest</artifactId>
    <version>${activiti.version}</version>

<dependency>
    <groupId>org.activiti</groupId>
    <artifactId>activiti-rest</artifactId>
    <version>${activiti.version}</version>
</dependency>


2、原理

ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

RuntimeService runtimeService = processEngine.getRuntimeService();
RepositoryService repositoryService = processEngine.getRepositoryService();
TaskService taskService = processEngine.getTaskService();
ManagementService managementService = processEngine.getManagementService();
IdentityService identityService = processEngine.getIdentityService();
HistoryService historyService = processEngine.getHistoryService();
FormService formService = processEngine.getFormService();

3、常见使用设计规则

（1）bpmn规范中：在编辑模型的时候，可给定任务执行人

（2）领取任务：在模型中没有指定执行人的时候，可以使用TaskService#claim领取任务（当然不领取任务，也是可以完成任务的）

（3）完成任务：为了业务的完整性，必须有人先领取任务，才能完成任务

（4）审批是否通过：activiti中有变量这一概念，通过这一概念，可以在流程完毕的时候，判断审批是否通过。      pass(dataType=Integer)://流程是否全部审批通过 1:全部通过 | 0:流程不通过

（5）流程模型设计：每个任务后面都设置一个互斥网关，一个是通过进入下一步，一个是不通过结束流程（赋值变量），这样在流程完成的时候根据变量判断流程是否审批通过

4、常用service封装

详见：https://git.oschina.net/bunic/qy-erp/tree/master/erp-common/src/main/java/com/qysxy/erp/framework/activiti

5、集成activiti-explore，web流程设计器

js包：https://git.oschina.net/bunic/qy-erp/tree/master/erp-acceptor/src/main/webapp/third/activiti

json接口：https://git.oschina.net/bunic/qy-erp/tree/master/erp-acceptor/src/main/java/com/qysxy/erp/common/activiti

/service/model/{modelId}/save

/service/model/{modelId}/json

/service/editor/stencilset
