什么是工作流?
工作流(Workflow),就是通过计算机对业务流程自动化执行管理。它主要解决的是“使在多个参与者之间按照某种预定义的规则自动进行传递文档、信息或任务的过程,从而实现某个预期的业务目标,或者促使此目标的实现”。
什么是Activiti?
Alfresco软件在2010年5月17日宣布Activiti业务流程管理(BPM)开源项目的正式启动,其首席架构师由业务流程管理BPM的专家 Tom Baeyens担任,Tom Baeyens就是原来jbpm的架构师,而jbpm是一个非常有名的工作流引擎,当然activiti也是一个工作流引擎。
Activiti是一个工作流引擎, activiti可以将业务系统中复杂的业务流程抽取出来,使用专门的建模语言(BPMN2.0)进行定义,业务系统按照预先定义的流程进行执行,实现了业务系统的业务流程由activiti进行管理,减少业务系统由于流程变更进行系统升级改造的工作量,从而提高系统的健壮性,同时也减少了系统开发维护成本。
什么是BPMN?
BPMN(Business Process Model And Notation)- 业务流程模型和符号 是由BPMI(Business Process Management Initiative)开发的一套标准的业务流程建模符号,使用BPMN提供的符号可以创建业务流程。 2004年5月发布了BPMN1.0规范.BPMI于2005年9月并入OMG(The Object Management Group对象管理组织)组织。OMG于2011年1月发布BPMN2.0的最终版本。
具体发展历史如下:
BPMN 是目前被各 BPM 厂商广泛接受的 BPM 标准。Activiti 就是使用 BPMN 2.0 进行流程建模、流程执行管理,它包括很多的建模符号,比如:
Event 用一个圆圈表示,它是流程中运行过程中发生的事情。
活动用圆角矩形表示,一个流程由一个活动或多个活动组成
一个bpmn图形的例子:
Bpmn图形其实是通过xml表示业务流程,上边的.bpmn文件使用文本编辑器打开:
一:在项目pom.xml文件中添加activity依赖。
- <dependency>
- <groupId>org.activiti</groupId>
- <artifactId>activiti-spring-boot-starter-basic</artifactId>
- <version>6.0.0</version>
- </dependency>
二:修改启动类。
@SpringBootApplication(exclude={org.activiti.spring.boot.SecurityAutoConfiguration.class})
三:流程文件。
在src/main/java/resources目录下新建processes目录,并在该目录下新增一个业务流程文件(默认以.bpmn20.xml或.bpmn为后缀名)(activity默认校验resources下的processes文件夹里的流程文件,如果没有processes目录并且目录下没有流程文件会报错class path resource [processes/] cannot be resolved to URL because it does not exist),
可以在配置文件中配置spring.activiti.check-process-definitions=false,设置为不校验,这样就不会报错。
四:修改activity默认的id生成策略。
1.activiti默认的ID生成策略在高并发场景下会出现ID重复的情况,因此在高并发场景下建议采用UUID的策略。
2.传统的spring在配置文件中添加idGenerator属性:
- <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
- <!-- UUID作为主键生成策略 -->
- <property name="idGenerator" ref="idGenerator" />
- </bean>
3.springboot中在配置类中修改idGenerator。
需要写一个类实现IdGenerator,并重写getNextId()方法;
activity也内置了一个实现类org.activiti.engine.impl.persistence.StrongUuidGenerator,生成的uuid是带'-'的
- package com.mycompany.myapp.config;
-
- import org.activiti.spring.SpringProcessEngineConfiguration;
- import org.activiti.spring.boot.ProcessEngineConfigurationConfigurer;
- import org.springframework.context.annotation.Configuration;
-
- import com.mycompany.myapp.utils.idGenerator;
-
- /**
- * @author www.wzbjsz.cn
- * @date 2019-01-09 10:26:47
- */
- @Configuration
- public class ActivitiConfig implements ProcessEngineConfigurationConfigurer {
-
- @Override
- public void configure(SpringProcessEngineConfiguration springProcessEngineConfiguration) {
- springProcessEngineConfiguration.setIdGenerator(new idGenerator());
- }
-
- }
- package com.mycompany.myapp.utils;
-
- import java.util.UUID;
-
- import org.activiti.engine.impl.cfg.IdGenerator;
-
- /**
- * @author www.wzbjsz.cn
- * @date 2019-01-09 10:47:59
- */
- public class idGenerator implements IdGenerator{
-
- /**
- * 封装JDK自带的UUID, 通过Random数字生成, 中间无-分割.
- */
- public static String uuid() {
- return UUID.randomUUID().toString().replaceAll("-", "");
- }
-
- /**
- * Activiti ID 生成
- */
- @Override
- public String getNextId() {
- return IdGen.uuid();
- }
-
- }
五:配置文件属性:
1.spring.activiti.database-schema-update
spring.activiti.database-schema-update=true
databaseSchemaUpdate配置项可以设置流程引擎启动和关闭时数据库执行的策略。 databaseSchemaUpdate有以下四个值:
- false:false为默认值,设置为该值后,Activiti在启动时,会对比数据库表中保存的版本,如果版本不匹配时,将在启动时抛出异常。
- true:设置为该值后,Activiti会对数据库中所有的表进行更新,如果表不存在,则Activiti会自动创建。
- create-drop:Activiti启动时,会执行数据库表的创建操作,在Activiti关闭时,执行数据库表的删除操作。
- drop-create:Activiti启动时,执行数据库表的删除操作在Activiti关闭时,会执行数据库表的创建操作。
设置为true后启动应用,会在数据库里创建28张表,表创建好之后停止应用,设置为false,每次应用启动不检查Activiti数据表是否存在及版本号是否匹配,以提升应用启动速度。
2.spring.activiti.history-level
- #保存历史数据级别设置为full最高级别,便于历史数据的追溯
- spring.activiti.history-level=full
对于历史数据,保存到何种粒度,Activiti提供了history-level属性对其进行配置。history-level属性有点像log4j的日志输出级别,该属性有以下四个值:
- none:不保存任何的历史数据,因此,在流程执行过程中,这是最高效的。
- activity:级别高于none,保存流程实例与流程行为,其他数据不保存。
- audit:除activity级别会保存的数据外,还会保存全部的流程任务及其属性。audit为history的默认值。
- full:保存历史数据的最高级别,除了会保存audit级别的数据外,还会保存其他全部流程相关的细节数据,包括一些流程参数等。
3.spring.activiti.check-process-definitions
- #关闭activiti自动部署(使用流程设计器部署,不使用具体文件访问方式)
- spring.activiti.check-process-definitions=false
六:集成在线流程设计器Activiti Modeler。
1.pom文件添加activiti-modeler依赖。
- <!-- https://mvnrepository.com/artifact/org.activiti/activiti-modeler -->
- <dependency>
- <groupId>org.activiti</groupId>
- <artifactId>activiti-modeler</artifactId>
- <version>5.22.0</version>
- <exclusions>
- <exclusion>
- <groupId>org.activiti</groupId>
- <artifactId>activiti-bpmn-model</artifactId>
- </exclusion>
- </exclusions>
- </dependency>
2.下载activiti5.22.0源码https://github.com/Activiti/Activiti/tree/activiti-5.22.0。
3.复制Activiti 5.22.0中Activiti\modules\activiti-webapp-explorer2\src\main\webapp中的diagram-viewer、editor-app两个文件夹和modeler.html文件到Spring Boot项目resources目录下的static文件夹下。
image.png
image.png
4.修改resource/static/editor-app/app-cfg.js。
image.png
改为:
- var ACTIVITI = ACTIVITI || {};
-
- ACTIVITI.CONFIG = {
- 'contextRoot' : '/service',
- };
5.复制Activiti\modules\activiti-webapp-explorer2\src\main\resources中的stencilset.json文件到Spring Boot项目中的resources目录下,activiti自带是英文的。
6.将Activiti 5.22.0源码中activiti-modeler中的下列3个java文件复制到自己的项目中,并在三个java类上添加注解@RequestMapping("/service")。(/service与上面app-cfg.js中保持一致)
image.png
image.png
7.修改ModelSaveRestResource.java文件:

-
- protected static final Logger LOGGER = LoggerFactory.getLogger(ModelSaveRestResource.class);
-

- outStream.close();
-
- } catch (Exception e) {
- LOGGER.error("Error saving model", e);
- throw new ActivitiException("Error saving model", e);
- }
- }
- }
8.测试创建模型。
- /**
- * 新建一个空模型
- * @return
- * @throws UnsupportedEncodingException
- */
- @GetMapping("/create")
- public void newModel(HttpServletRequest request,HttpServletResponse response) throws Exception {
- //初始化一个空模型
- Model model = repositoryService.newModel();
-
- //设置一些默认信息
- String name = "new-process";
- String description = "";
- int revision = 1;
- String key = "process";
-
- ObjectNode modelNode = objectMapper.createObjectNode();
- modelNode.put(ModelDataJsonConstants.MODEL_NAME, name);
- modelNode.put(ModelDataJsonConstants.MODEL_DESCRIPTION, description);
- modelNode.put(ModelDataJsonConstants.MODEL_REVISION, revision);
-
- model.setName(name);
- model.setKey(key);
- model.setMetaInfo(modelNode.toString());
-
- repositoryService.saveModel(model);
- String id = model.getId();
-
- //完善ModelEditorSource
- ObjectNode editorNode = objectMapper.createObjectNode();
- editorNode.put("id", "canvas");
- editorNode.put("resourceId", "canvas");
- ObjectNode stencilSetNode = objectMapper.createObjectNode();
- stencilSetNode.put("namespace",
- "http://b3mn.org/stencilset/bpmn2.0#");
- editorNode.set("stencilset", stencilSetNode);
- repositoryService.addModelEditorSource(id,editorNode.toString().getBytes("utf-8"));
- response.sendRedirect("/modeler.html?modelId="+id);
- }
9.请求创建模型接口后,显示如下页面表示成功:
image.png
10.去掉Activiti Afresco的logo标题栏,并且把样式上的空白栏去掉。
1)修改modeler.html中的以下内容,注意不要把该文本删除,建议加style=”display:none”,删除后其会造成底层下的一些内容有40个像数的东西显示不出来,也可以直接删除掉。
- <div style="display:none" class="navbar navbar-fixed-top navbar-inverse" role="navigation" id="main-header">
- <div class="navbar-header">
- <a href="" ng-click="backToLanding()" class="navbar-brand"
- title="{{'GENERAL.MAIN-TITLE' | translate}}"><span
- class="sr-only">{{'GENERAL.MAIN-TITLE' | translate}}</span></a>
- </div>
- </div>
2)在editor-app/css/style-common.css中,把以下样式的padding-top部分改为0px;
- .wrapper.full {
- padding: 0px 0px 0px 0px;
- overflow: hidden;
- max-width: 100%;
- min-width: 100%;
- }
11.保存模型如果报错获取不到参数。(http://www.wzbjsz.cn),添加过滤器:
- package com.mycompany.myapp.config;
-
- import javax.servlet.annotation.WebFilter;
-
- import org.springframework.core.annotation.Order;
- import org.springframework.stereotype.Component;
- import org.springframework.web.filter.HttpPutFormContentFilter;
-
- /**
- * @author www.wzbjsz.cn
- * @date 2019-01-20 15:47:39
- */
- @Component
- @WebFilter(urlPatterns = "/*", filterName = "putFilter")
- @Order(Integer.MIN_VALUE)
- public class PutFilter extends HttpPutFormContentFilter {
-
- }
-
七.modeler相关方法的封装。
- package com.lhtc.jv.vo;
-
- import java.io.Serializable;
-
- import javax.validation.constraints.NotNull;
-
- import lombok.Data;
-
