流程部署创建主要影响以下几张表

ACT_RE_*：’RE’表示repository（存储）。RepositoryService接口操作的表。带此前缀的表包含的是静态信息，如，流程定义，流程的资源（图片，规则等）。

flowable流程创建是由DeploymentBuilder接口提供，支持以下几种方式创建：

    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输入流创建：

//在resources文件夹下创建 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();

以上创建部署时的方法返回的结果还是DeploymentBuilder接口 。所以，如果要是创建多个bpmn，可以在后面追加如下代码：

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

addClasspathResource （springboot项目会常用），resources文件夹下创建：

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

此种方式，无需转换成InputStream

addString方式，可以通过字符串直接进行创建：

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字节方式：

可以根据上面的addString方式进行修改，将UNSAFE_XML字符串转换为Bytes[]数组

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

addZipInputStream zip压缩包方式：

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

addBpmnModel BpmnModel模型方式创建：

        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("模型方式创建流程", model).deploy();

最后：注意，无论哪种方式加载 模型名称 也就是 resourcesName 结尾必须以bpmn20.xml, bpmn为结尾，不然不会插入ACT_RE_PROCDEF 流程定义表，源码位置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()));//此处根据名称判断是否符合规规范

            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);
            }
        }
