前沿：有时候工作流需要实现用户自己画图，自己部署，自己启动，但是流程a.bpmn.xml这个东西一般都是程序员去画的也就是说，如果用户画图，怎么将界面简单化，这就是一个问题，如何将用户画的流程变成activiti框架人事的a.bpmn.xml，并且运转也是一个问题。
如下界面是我设计斌切提出web数据结构，然后转化成activiti认识的bpmn文件，并且可以使用的流程代码转换。
一、部署篇
public Boolean deployByJson(CustomizeProcessVo customizeProcessVo) throws XMLException {
Boolean flag = false;
if (customizeProcessVo.getFlowJson() == null) {
throw new ServiceException("自定义流程为空");
}
Boolean result = actService.deployByJson(customizeProcessVo);
if (result) {
flag = true;
}
return flag;
}
}使用的是字符串部署方式，并且存储文件到本地，也就是说本地有bpmn的文件，再读取本地文件进行部署，为什么这么做呢，因为我也不知道为啥直接字符串部署部署失败
/**
* 此类是用来 字符串部署工作流
*
* @param customizeProcessVo 自定义工作流对象
* @return
* @data 2018-05-14

FileInputStream bpmnfileInputStream = null;
Boolean result = false;
//自定义流程名称和ID (name)CONTRACT_SIGN_PDKEY_168 Process (ID)CONTRACT_SIGN_PDKEY_168
Map<Integer, String> mapProcess = new HashedMap();
mapProcess.put(1, customizeProcessVo.getPdKey());
mapProcess.put(2, customizeProcessVo.getPdKey() + " Process");
mapProcess.put(3, "true");
