• 1、首先是根据流程ID获取当前任务：Listtasks=taskService.createTaskQuery.processInstanceIdprocInstanceId.list;2、然后根据当前任务获取当前流程的流程定义，然后根据流程定义获得所有的节点：ProcessDefinitionEntitydef=P..。

• 建议你可以看一下咖啡兔的相关技术博文：网页链接，activiti6和activiti5整合方式一致1.为什么要整合Activiti5.10版本把原本独立的ActivitiModeler模块整合到了ActivitiExplorer中，两者相结合使用起来很方便，通过Modeler设计的流程模型可以直接部署到引擎，也可以把已经部署的流程转换为Model从而在Modeler中编辑。在实际应用中也有这样的需求，把Modeler整合到业务系统中可以供管理员使用，或者作为BPM平台的一部分存在，很遗憾官方没有给出如何整合Modeler的文档。2.整合工作2.1下载源码首先需要从Github下载源码：https://github.com/Activiti/Activiti；可以直接用Git克隆，也可以下载zip格式的压缩包。2.2复制文件复制的所有文件均在activiti-webapp-explorer2目录中。src/main/resources中的editor.html、stencilset.json、plugins.xml到项目源码的源码根目录，保证编译之后在classes根目录src/main/webapp中的api、editor、explorer、libs到项目的webapp目录2.3添加依赖?123456789101112131415161718192021222324      org.activiti    activiti-explorer    5.14                        vaadin            com.vaadin                            dcharts-widget            org.vaadin.addons                            activiti-simple-workflow            org.activiti                org.activiti    activiti-modeler    5.14  2.4添加Java类添加一个ExplorerRestApplication.java类保存到项目中，注册了一些REST路由。1234567891011121314151617181920212223242526272829  packageorg.activiti.explorer.rest.application; importorg.activiti.editor.rest.application.ModelerServicesInit;importorg.activiti.rest.api.DefaultResource;importorg.activiti.rest.application.ActivitiRestApplication;importorg.activiti.rest.filter.JsonpFilter;importorg.restlet.Restlet;importorg.restlet.routing.Router; publicclassExplorerRestApplicationextendsActivitiRestApplication{   publicExplorerRestApplication{    super;  }  /**   *CreatesarootRestletthatwillreceiveallincomingcalls.   */  @Override  publicsynchronizedRestletcreateInboundRoot{    Routerrouter=newRoutergetContext;    router.attachDefaultDefaultResource.class;    ModelerServicesInit.attachResourcesrouter;    DiagramServicesInit.attachResourcesrouter;    JsonpFilterjsonpFilter=newJsonpFiltergetContext;    jsonpFilter.setNextrouter;    returnjsonpFilter;  } }  2.5配置web.xml在web.xml文件中添加如下配置：?12345678910111213141516      RestletServlet    org.restlet.ext.servlet.ServerServlet         RestletServlet    /service/*  2.6控制器使用SpringMVC做了一个简单的封装，也可以使用其他的MVC实现。123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102103104105106107108109110111112113114115116117118119120191122123124125126127128129130131132133134135136137138139140141142143144145146147148149150151152153154155156157158159160161162163  packageme.kafeitu.demo.activiti.web.workflow; importjava.io.ByteArrayInputStream;importjava.util.List; importjavax.servlet.http.HttpServletRequest;importjavax.servlet.http.HttpServletResponse; importorg.activiti.bpmn.converter.BpmnXMLConverter;importorg.activiti.bpmn.model.BpmnModel;importorg.activiti.editor.constants.ModelDataJsonConstants;importorg.activiti.editor.language.json.converter.BpmnJsonConverter;importorg.activiti.engine.RepositoryService;importorg.activiti.engine.repository.Deployment;importorg.activiti.engine.repository.Model;importorg.apache.commons.io.IOUtils;importorg.apache.commons.lang3.StringUtils;importorg.codehaus.jackson.JsonNode;importorg.codehaus.jackson.map.ObjectMapper;importorg.codehaus.jackson.node.ObjectNode;importorg.slf4j.Logger;importorg.slf4j.LoggerFactory;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.stereotype.Controller;importorg.springframework.web.bind.annotation.PathVariable;importorg.springframework.web.bind.annotation.RequestMapping;importorg.springframework.web.bind.annotation.RequestParam;importorg.springframework.web.servlet.ModelAndView;importorg.springframework.web.servlet.mvc.support.RedirectAttributes; /** *流程模型控制器 * *@authorhenryyan */@Controller@RequestMappingvalue="/workflow/model"publicclassModelController{   protectedLoggerlogger=LoggerFactory.getLoggergetClass;   @Autowired  RepositoryServicerepositoryService;   /**   *模型列表   */  @RequestMappingvalue="list"  publicModelAndViewmodelList{    ModelAndViewmav=newModelAndView"workflow/model-list";    Listlist=repositoryService.createModelQuery.list;    mav.addObject"list",list;    returnmav;  }   /**   *创建模型   */  @RequestMappingvalue="create"  publicvoidcreate@RequestParam"name"Stringname,@RequestParam"key"Stringkey,@RequestParam"description"Stringdescription,          HttpServletRequestrequest,HttpServletResponseresponse{    try{      ObjectMapperobjectMapper=newObjectMapper;      ObjectNodeeditorNode=objectMapper.createObjectNode;      editorNode.put"id","canvas";      editorNode.put"resourceId","canvas";      ObjectNodestencilSetNode=objectMapper.createObjectNode;      stencilSetNode.put"namespace","http://b3mn.org/stencilset/bpmn2.0#";      editorNode.put"stencilset",stencilSetNode;      ModelmodelData=repositoryService.newModel;       ObjectNodemodelObjectNode=objectMapper.createObjectNode;      modelObjectNode.putModelDataJsonConstants.MODEL_NAME,name;      modelObjectNode.putModelDataJsonConstants.MODEL_REVISION,1;      description=StringUtils.defaultStringdescription;      modelObject

• runtimeService.suspendProcessInstanceByIdprocessInstanceId挂起该流程实例。也就是冻结暂停。也可激活。Activiti是一个项目的名称，Alfresco软件在2019年5月17日宣布Activiti业务流程管理，面对新技术的机遇，诸如互操作性和云架构，提供技术实现。创始人TomBaeyens是JBossjBPM的项目架构师，以及另一位架构师JoramBarrez，一起加入到创建Alfresco这项首次实现Apache开源许可的BPMN2.0引擎开发中来。
