1、获取排他网关分支名称、分支表达式、下一级任务节点
/**
* 获取排他网关分支名称、分支表达式、下一级任务节点
* @param flowElement
* @param data
* add by nbacheng
*/
private Map<String, Object> GetExclusiveGatewayUser(FlowElement flowElement,Map<String, Object> variables){
// 获取所有网关分支
List<SequenceFlow> targetFlows=((ExclusiveGateway)flowElement).getOutgoingFlows();
// 循环每个网关分支
for(SequenceFlow sequenceFlow : targetFlows){
// 获取下一个网关和节点数据
FlowElement targetFlowElement=sequenceFlow.getTargetFlowElement();
// 网关数据不为空
if (StringUtils.isNotBlank(sequenceFlow.getConditionExpression())) {
// 获取网关判断条件
String expression = sequenceFlow.getConditionExpression();
if (expression == null ||Boolean.parseBoolean(
String.valueOf(
FindNextNodeUtil.result(variables, expression.substring(expression.lastIndexOf("{") + 1, expression.lastIndexOf("}")))))) {
// 网关出线的下个节点是用户节点
if(targetFlowElement instanceof UserTask){
// 判断是否是会签
UserTask userTask = (UserTask) targetFlowElement;
MultiInstanceLoopCharacteristics multiInstance = userTask.getLoopCharacteristics();
if (Objects.nonNull(multiInstance)) {//下个节点是会签节点

}2、获取多实例会签用户信息

**/

for(SysUser sysuser : templist) {
SysUser sysUserTemp = sysUserService.selectUserById(sysuser.getUserId());
list.add(sysUserTemp);
}
}
sysuserlist = list.stream().map(obj-> (String) obj.getUserName()).collect(Collectors.toList());
}

List<SysUser> list = new ArrayList<SysUser>();

* @param taskId 当前节点id
