 在设置会签时有两个地方要注意：

1、会签的Collection设置为变量，Sequential参数的true代表必须按照传入的用户顺序一个一个的执行会签，而false则可以并行执行会签，建议设置为false

2、会签有最少有两个地方需要设置，分别是Main config和Collection，在Multi instance面板中的Element variable中设置了变量后，需要在Main Config中设置当前操作人

 

部署activiti工作流

@Autowired
private RepositoryService rep;
	
public void deployment() throws Exception {
        //bpmn文件必须已经在工作目录下面
	//部署子流程
	rep.createDeployment().addClasspathResource("child.bpmn").deploy();
        //部署主流程
	rep.createDeployment().addClasspathResource("MyProcess.bpmn").deploy();
        //通过文件流进行部署
        FileInputStream stream = new FileInputStream("d:/MyProcess.bpmn");
	rep.createDeployment().addInputStream("child", stream).deploy();
}
