论文地址:https://arxiv.org/pdf/2303.10404.pdf代码:未开源目前是MOT20的第二名1.Abstract这篇文章着力于解决长时跟踪的问题.当前大多数方法只能依靠Re-ID特征来进行长时跟踪,也就是轨迹长期丢失后的再识别.然而,Re-ID特征并不总是有效的.尤其是在拥挤和极度遮挡的情况下.为此,这篇文章提出了MotionTrack,包括两个方面:设计了一个交互模块(InteractionModule),来学习短轨迹之间的相互作用.简单来说,就是根据目标相邻两帧的的偏移,计算出一个表征目标之间相互影响的矩阵,随后利用该矩阵经过一个GCN和MLP来直接得到目标的预测
问题：在用在SpringBoot集成Druid项目中，发现日志出现如下错误信息：discardlongtimenonereceivedconnection.jdbcUrl:jdbc:mysql://localhost:3306/test?autoReconnect=true&useUnicode=true&characterEncoding=utf8&serverTimezone=CTT,jdbcUrl:jdbc:mysql://localhost:3306/test?autoReconnect=true&useUnicode=true&characterEncoding=utf8&serve
问题背景在项目启动时出现大量c.a.d.pool.DruidAbstractDataSource:discardlongtimenonereceivedconnection.明显是Druid管理的数据库连接因为太长时间没有收到数据库发来的数据，把连接给回收掉了，这导致服务在启动时因为要重复创建连接让服务启动时间延长。定位原因根据错误信息，找到Druid源码com.alibaba.druid.pool.DruidAbstractDataSource#testConnectionInternal(com.alibaba.druid.pool.DruidConnectionHolder,java.s

话不多说，直接上代码ListLong>list=Arrays.asList(1L,2L,3L);Stringresult=list.stream().map(Object::toString).collect(Collectors.joining(","));System.out.println(result);//输出"1,2,3"这里，我们首先将List转换为Stream，然后使用map()方法将每个Long类型的元素转换为字符串类型，再使用Collectors.joining()方法将所有字符串连接起来并用逗号和空格分隔。需要注意的是，Collectors.joining()方法返回的是
