我可以通过MSSQLSconnectionFactory获得连接，但当我们需要同时更新1000多条记录时，我们会发现错误，因此我认为连接池应该更适合我们

这是测试代码：

@Test
    void simpleTest() {
        pushMesgApiRepository.findAllPushStatus("4")
        .subscribe(
            obj -> {
                obj.setPUSH_TIME((new java.util.Date()).toInstant()
                                      .atZone(ZoneId.systemDefault()).toLocalDateTime());
                            
                pushMesgApiRepository.save(obj)
                .subscribe(
                        elem->{
                            System.out.println("Register updated: " + elem);                        },
                        err->{
                            System.out.println("Register failed: "  + obj);
                            err.printStackTrace();
                        });
            },
            err->err.getSuppressed());
        
        
        }

这就是我得到的错误：

我还尝试通过DatabaseClient对象而不是ReactiveCrudepository来实现这一点

ConnectionPoolConfiguration configuration = ConnectionPoolConfiguration.builder(connectionFactory)
                    .maxIdleTime(Duration.ofMinutes(30))
                    .initialSize(10)
                    .maxSize(30)
                    //.maxCreateConnectionTime(Duration.ofSeconds(1))
                    .build();
        
        
        client = DatabaseClient.create(new ConnectionPool(configuration));

我得到了一条更详细的错误消息：（在我看来，错误与依赖项有关）

ConnectionPoolConfiguration configuration = ConnectionPoolConfiguration.builder(connectionFactory)
                    .maxIdleTime(Duration.ofMinutes(30))
                    .initialSize(10)
                    .maxSize(30)
                    //.maxCreateConnectionTime(Duration.ofSeconds(1))
                    .build();
        
        
        client = DatabaseClient.create(new ConnectionPool(configuration));
