1.首先通过bpmnjs进行工作流绘制，目前bpmnjs支持camunda工作流绘制，但对activiti工作流绘制不支持，这没关系，修改一下生成的bpmn文件就好了，这不是重点，就不介绍了，工作流绘制如下图：
2.将生成的bpmn内容上传到后台进行发布，生成的内容如下。

import javax.annotation.Resource; import org.activiti.engine.RepositoryService; import org.activiti.engine.RuntimeService; import org.activiti.engine.TaskService; import org.activiti.engine.repository.DeploymentBuilder; import org.springframework.transaction.annotation.Propagation; import org.springframework.transaction.annotation.Transactional; import com.goldenbridge.recognizesystem.service.IActivitiService; /** *@author create by pengweikang *@date 2018年4月4日--下午7:19:09 *@problem *@answer *@action */ public class ActivitiService implements IActivitiService{ @Resource private RepositoryService repositoryService; @Resource private RuntimeService runtimeService; @Resource private TaskService taskService; /* (non-Javadoc) * @see com.goldenbridge.recognizesystem.service.IActivitiService#create() */ @Override @Transactional(propagation=Propagation.REQUIRED) public void create(String bpmn) { String sourceReplace = "xmlns:activiti=\"http://activiti.org/bpmn"; String oldReplace = "xmlns:camunda=\"http://camunda.org/schema/1.0/bpmn"; int index = bpmn.indexOf(oldReplace); String result = ""; if(index > -1) { result = bpmn.replace(oldReplace, sourceReplace); } result = result.replaceAll("camunda", "activiti"); String name = System.currentTimeMillis()+""; DeploymentBuilder builder = repositoryService.createDeployment(); builder.name(name); builder.addString(name, bpmn); builder.deploy(); } }4.发现问题，打印日志如下图，只对部署单元（ACT_RE_DEPLOYMENT）和资源（ACT_GE_BYTEARRAY）进行插入，没有去部署流程（ACT_RE_PROCDEF）。
5.进行调试源码，发现源码会对resourceName进行校验，需要以bpmn或者bpmn20.xml结尾的资源内容才会去部署流程，如下图，而我的resourceName时通过当前时间获取的一串数字，因此才没有去部署流程。
6.解决问题。
7.运行结果。
