流程部署創(chuàng)建主要影響以下幾張表

ACT_RE_*：’RE’表示repository（存儲(chǔ)）。RepositoryService接口操作的表。帶此前綴的表包含的是靜態(tài)信息，如，流程定義，流程的資源（圖片，規(guī)則等）。

flowable流程創(chuàng)建是由DeploymentBuilder接口提供，支持以下幾種方式創(chuàng)建：

    DeploymentBuilder addInputStream(String var1, InputStream var2);

    DeploymentBuilder addClasspathResource(String var1);

    DeploymentBuilder addString(String var1, String var2);

    DeploymentBuilder addBytes(String var1, byte[] var2);

    DeploymentBuilder addZipInputStream(ZipInputStream var1);

    DeploymentBuilder addBpmnModel(String var1, BpmnModel var2);

addInputStream輸入流創(chuàng)建：

//在resources文件夾下創(chuàng)建 org/flowable/engine/test/repository/one.bpmn20.xml
InputStream bpmnInputStream = this.getClass().getClassLoader().getResourceAsStream("org/flowable/engine/test/repository/one.bpmn20.xml");
Deployment deployment = repositoryService.createDeployment()
                .addInputStream("one.bpmn20.xml", bpmnInputStream)
                .deploy();

以上創(chuàng)建部署時(shí)的方法返回的結(jié)果還是DeploymentBuilder接口 。所以，如果要是創(chuàng)建多個(gè)bpmn，可以在后面追加如下代碼：

Deployment deployment = repositoryService.createDeployment()
                .addInputStream("one.bpmn20.xml", bpmnInputStream)
                .addInputStream("two.bpmn20.xml", bpmnInputStream)
                .deploy();

addClasspathResource （springboot項(xiàng)目會(huì)常用），resources文件夾下創(chuàng)建：

repositoryService.createDeployment().addClasspathResource("org/flowable/engine/test/db/processOne.bpmn20.xml").deploy();

此種方式，無需轉(zhuǎn)換成InputStream

addString方式，可以通過字符串直接進(jìn)行創(chuàng)建：

private static String UNSAFE_XML = "<?xml version='1.0' encoding='UTF-8'?>" + "<!-- Billion Laugh attacks : http://portal.sliderocket.com/CJAKM/xml-attacks -->" + "<!DOCTYPE lols ["
            + "<!ENTITY lol 'lol'>" + "<!ENTITY lol1 '&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;'>" + "<!ENTITY lol2 '&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;'>"
            + "<!ENTITY lol3 '&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;&lol2;'>" + "<!ENTITY lol4 '&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;&lol3;'>"
            + "<!ENTITY lol5 '&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;&lol4;'>" + "<!ENTITY lol6 '&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;&lol5;'>"
            + "<!ENTITY lol7 '&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;&lol6;'>" + "<!ENTITY lol8 '&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;&lol7;'>"
            + "<!ENTITY lol9 '&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;&lol8;'>" + "]>" + "<lolz>&lol9;</lolz>" + "<definitions " + "xmlns='http://www.omg.org/spec/BPMN/20100524/MODEL'"
            + "xmlns:activiti='http://activiti.org/bpmn'" + "targetNamespace='Examples'>" + "<process id='oneTaskProcess' name='The One org.flowable.task.service.Task Process'>"
            + "  <documentation>This is a process for testing purposes</documentation>" + " <startEvent id='theStart' />" + " <sequenceFlow id='flow1' sourceRef='theStart' targetRef='theTask' />"
            + " <userTask id='theTask' name='my task' />" + " <sequenceFlow id='flow2' sourceRef='theTask' targetRef='theEnd' />" + " <endEvent id='theEnd' />" + "</process>" + "</definitions>";

repositoryService.createDeployment().addString("test.bpmn20.xml", UNSAFE_XML).deploy().getId();

addBytes字節(jié)方式：

可以根據(jù)上面的addString方式進(jìn)行修改，將UNSAFE_XML字符串轉(zhuǎn)換為Bytes[]數(shù)組

repositoryService.createDeployment().addString("Bytes[]方式測(cè)試", String.valueOf(UNSAFE_XML .getBytes("UTF-8"))).deploy();

addZipInputStream zip壓縮包方式：

InputStream inputStream = this.getClass()
        .getClassLoader()
        .getResourceAsStream("org/flowable/engine/test/api/repository/test-processes.zip");

addBpmnModel BpmnModel模型方式創(chuàng)建：

        org.flowable.bpmn.model.Process process = new org.flowable.bpmn.model.Process();
        process.setId("oneTaskProcess");
        process.setName("The one task process");

        StartEvent startEvent = new StartEvent();
        startEvent.setId("start");
        startEvent.setName("The start");
        process.addFlowElement(startEvent);

        UserTask userTask = new UserTask();
        userTask.setName("The Task");
        userTask.setId("theTask");
        userTask.setAssignee("kermit");
        process.addFlowElement(userTask);

        EndEvent endEvent = new EndEvent();
        endEvent.setId("theEnd");
        endEvent.setName("The end");
        process.addFlowElement(endEvent);

        process.addFlowElement(new SequenceFlow("start", "theTask"));
        process.addFlowElement(new SequenceFlow("theTask", "theEnd"));

        BpmnModel model = new BpmnModel();
        model.addProcess(process);
      repositoryService.createDeployment().addBpmnModel("模型方式創(chuàng)建流程", model).deploy();

最后：注意，無論哪種方式加載 模型名稱 也就是 resourcesName 結(jié)尾必須以bpmn20.xml, bpmn為結(jié)尾，不然不會(huì)插入ACT_RE_PROCDEF 流程定義表，源碼位置ParsedDeploymentBuilder.class->build()

while(true) {
            EngineResource resource;
            do {
                if (!var5.hasNext()) {
                    return new ParsedDeployment(deploymentEntity, processDefinitions, processDefinitionsToBpmnParseMap, processDefinitionsToResourceMap);
                }

                resource = (EngineResource)var5.next();
            } while(!this.isBpmnResource(resource.getName()));//此處根據(jù)名稱判斷是否符合規(guī)規(guī)范

            LOGGER.debug("Processing BPMN resource {}", resource.getName());
            BpmnParse parse = this.createBpmnParseFromResource(resource);
            Iterator var8 = parse.getProcessDefinitions().iterator();

            while(var8.hasNext()) {
                ProcessDefinitionEntity processDefinition = (ProcessDefinitionEntity)var8.next();
                processDefinitions.add(processDefinition);
                processDefinitionsToBpmnParseMap.put(processDefinition, parse);
                processDefinitionsToResourceMap.put(processDefinition, resource);
            }
        }
