在多个线程上运行时出现 Quarkus 事务错误

问：

当我运行post到 http://localhost:80/poc/copyOne 时，代码运行良好，但是当我卷曲 http://localhost:80/poc/streamHPO/2 时，它失败并显示以下消息：

无法使用 EntityManager/Session，因为事务和 CDI 请求上下文都处于活动状态。请考虑将@Transactional添加到方法中以自动激活事务，或者@ActivateRequestContext如果您有正当理由不使用事务

我正在使用MSSQL服务器（不确定它是否相关），以及HighPriorityOpenEntity和ComPocTtEntity的PanacheEntityBase-s

@GET
    @Path("/streamHPO/{maxt}")
    public Response streamHPO(@PathParam("maxt") int maxt) throws IOException {

        new Thread(() ->
        {
            try {
                streamHPOThread(maxt);
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
        }).start();
        return Response.ok().build();
    }

            System.out.println("HPO: " + c + " of " + s);
        }
    }
