一、Activiti7简介
Activiti7是一个基于BPMN2.0和CMMN1.1的工作流和业务流程管理系统,是Activiti团队开发的一款全新的产品,它是一个全新的Activiti Cloud 生态系统中的一个组成模块,基于Spring Cloud构建,并提供了许多可扩展和可插拔的功能。
Activiti7提供了一组功能强大的工具,可以为开发人员提供业务流程管理方案。这些功能包括流程引擎、子任务管理、事件处理、任务路由、异步消息、定时器、计数器和错误处理等。Activiti7将所有这些功能整合到一个完整的基于云的解决方案中,因此用户不再需要使用复杂的服务器和数据库管理方案。
Activiti7是开源的,任何人都可以免费使用它。Activiti开发团队还提供了基于许可证的附加服务,其中包括专家支持、技术培训和更新升级等。
二、Activiti7中文详细教程
如何使用Activiti7建立自己的业务流程管理系统?以下是一个简单的以销售流程为例子的Activiti7中文详细教程。
1、流程定义文件
首先,需要在Activiti7中定义流程文件。Activiti7支持BPMN2.0,可以使用Activiti Modeler或其他BPMN编辑器创建和编辑BPMN流程文件。下面是一个简单的BPMN2.0流程定义文件示例:
<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.omg.org/spec/BPMN/20100524/MODEL BPMN20.xsd"
id="sale-process"
targetNamespace="http://example.com/sale-process">
<process id="sales-process" name="销售流程">
<startEvent id="start"
name="开始销售流程"/>
<sequenceFlow id="to-check-stock"
name="检查库存"
sourceRef="start"
targetRef="check-stock"/>
<exclusiveGateway id="is-stock-ok"
name="库存是否充足"/>
<sequenceFlow id="yes-stock-ok"
name="库存充足"
sourceRef="is-stock-ok"
targetRef="check-credit"/>
<sequenceFlow id="no-stock-ok"
name="库存不充足"
sourceRef="is-stock-ok"
targetRef="end"/>
<sequenceFlow id="to-check-credit"
name="检查信用"
sourceRef="check-stock"
targetRef="check-credit"/>
<exclusiveGateway id="is-credit-ok"
name="信用是否充足"/>
<sequenceFlow id="yes-credit-ok"
name="信用充足"
sourceRef="is-credit-ok"
targetRef="end"/>
<sequenceFlow id="no-credit-ok"
name="信用不充足"
sourceRef="is-credit-ok"
targetRef="end"/>
<endEvent id="end"
name="结束销售流程"/>
</process>
</definitions>
2、部署流程定义文件
部署流程定义文件,可以使用Activiti REST API或Activiti Modeler来完成。以下是使用Activiti REST API部署流程定义文件的示例代码:
RestTemplate restTemplate = new RestTemplate();
// Create headers with username and password
String plainCreds = "activiti:activiti";
byte[] plainCredsBytes = plainCreds.getBytes();
byte[] base64CredsBytes = Base64.getEncoder().encode(plainCredsBytes);
String base64Creds = new String(base64CredsBytes, "UTF-8");
HttpHeaders headers = new HttpHeaders();
headers.add("Authorization", "Basic " + base64Creds);
// Create the body of the request
MultiValueMap<String, Object> map= new LinkedMultiValueMap<String, Object>();
map.add("file", new FileSystemResource("path/to/definition.bpmn"));
// Create the request entity
HttpEntity<MultiValueMap<String, Object>> request = new HttpEntity<>(map, headers);
// Call the Activiti REST API for deployment
ResponseEntity<Object> response = restTemplate.postForEntity("http://localhost:8080/activiti-rest/service/repository/deployments", request, Object.class);
3、启动流程实例
接下来,需要启动销售流程的一个实例。以下是使用Activiti REST API启动流程实例的示例代码:
RestTemplate restTemplate = new RestTemplate();
// Create headers with username and password
String plainCreds = "activiti:activiti";
byte[] plainCredsBytes = plainCreds.getBytes();
byte[] base64CredsBytes = Base64.getEncoder().encode(plainCredsBytes);
String base64Creds = new String(base64CredsBytes, "UTF-8");
HttpHeaders headers = new HttpHeaders();
headers.add("Authorization", "Basic " + base64Creds);
// Create the body of the request
Map<String, Object> vars = new HashMap();
vars.put("employee", "Alice");
vars.put("customer", "Bob");
vars.put("amount", 1000);
vars.put("pricePerUnit", 100);
vars.put("currency", "USD");
HttpEntity<Map<String, Object>> request = new HttpEntity<>(vars, headers);
// Call the Activiti REST API to start process instance
ResponseEntity<Object> response = restTemplate.postForEntity("http://localhost:8080/activiti-rest/service/runtime/process-instances/sales-process/start", request, Object.class);
4、处理任务
流程定义文件中定义了流程需要执行的任务,根据任务定义启动流程实例后,可以通过Activiti REST API获取当前流程实例的任务列表并进行处理。以下是使用Activiti REST API获取当前任务列表的示例代码:
RestTemplate restTemplate = new RestTemplate();
// Create headers with username and password
String plainCreds = "activiti:activiti";
byte[] plainCredsBytes = plainCreds.getBytes();
byte[] base64CredsBytes = Base64.getEncoder().encode(plainCredsBytes);
String base64Creds = new String(base64CredsBytes, "UTF-8");
HttpHeaders headers = new HttpHeaders();
headers.add("Authorization", "Basic " + base64Creds);
// Call the Activiti REST API to get task list for process instance
ResponseEntity<Object> response = restTemplate.getForEntity("http://localhost:8080/activiti-rest/service/runtime/tasks?processInstanceId={processInstanceId}",
Object.class, processInstanceId);
