说明原因：

引入pgjdbc相关包，与mongo数据库共用时，出现问题  

处理方法：

CompletableFuture.supplyAsync(()->{},dbExecutor.executor());

return CompletableFuture.supplyAsync(()->{
  Graph graph = jongo.getCollection(TransConstant.work_graph)
      .findOne(new ObjectId(id)).as(Graph.class);//mongo查询
  if (graph != null) {
    RiskGraph2Dto dto = new RiskGraph2Dto();
  dto.setNodes3(graphDomain.getNodeLayers(id));//pg查询
  dto.setEdges3(graphDomain.getEdgeLayers(id));//pg查询
    return dto;
  }
  return null;
},dbExecutor.executor());
