activiti7.0.0.SR1 流程设计器问题
最近在看activiti70相关,然后看到这么一个博客:https://blog.csdn.net/qq_40451631/article/details/84937251 感觉收获很大,初步集成activiti7.0.0.SR1完成,但在此博客中,流程图使用的是5.18的eclipse插件,故突发奇想使用5.22网页流程设计器是否可行,最后用6.0的集成方式成功集成进去了,但是在查看流程图时图片无法成功生成,请问可能是什么原因?还是说我的这个想法本身就是错的?

SpringBoot+Activiti5.22如何统一事务
各位大侠: 目前我在整合项目时SpringBoot1.5.2+Activiti5.22时启动项目后,activiti的mybatis的数据连接一直有问题。 我debug了下,看到ProcessEngineConfigurationImpl的init方法全部执行结束,没有报错,而且activiti也找到了DataSource,但是往下走时控制台一直刷一个日志,好像是数据连接池一直在打开和关闭。代码如下: 17:07:26.813 [Thread-8] DEBUG o.a.i.t.managed.ManagedTransaction - Opening JDBC Connection 17:07:26.815 [Thread-7] DEBUG o.a.i.t.managed.ManagedTransaction - Closing JDBC Connection [Transaction-aware proxy for target Connection [ProxyConnection[PooledConnection[com.mysql.jdbc.JDBC4Connection@457547a1]]]] 17:07:26.817 [Thread-8] DEBUG o.a.i.t.managed.ManagedTransaction - Closing JDBC Connection [Transaction-aware proxy for target Connection [ProxyConnection[PooledConnection[com.mysql.jdbc.JDBC4Connection@5f400587]]]] 17:07:36.821 [Thread-7] DEBUG o.a.i.t.managed.ManagedTransaction - Opening JDBC Connection 17:07:36.822 [Thread-8] DEBUG o.a.i.t.managed.ManagedTransaction - Opening JDBC Connection 17:07:36.823 [Thread-7] DEBUG o.a.i.t.managed.ManagedTransaction - Closing JDBC Connection [Transaction-aware proxy for target Connection [ProxyConnection[PooledConnection[com.mysql.jdbc.JDBC4Connection@5f400587]]]] 17:07:36.825 [Thread-8] DEBUG o.a.i.t.managed.ManagedTransaction - Closing JDBC Connection [Transaction-aware proxy for target Connection [ProxyConnection[PooledConnection[com.mysql.jdbc.JDBC4Connection@457547a1]] 如果我删除掉activiti的依赖包,启动项目,项目是正常的。添加上activiti的依赖包之后,就会有这个问题,但是用Junit去执行activiti的数据操作又是没有问题的。就是我项目的controller方法不能正常被访问了,访问就报404。 求大神助我。

SpringBoot +MybatisPlus +activiti整合版本冲突,有没有整合没冲突的组合,求推荐!
SpringBoot+MybatisPlus+activiti整合时因该是出现了版本冲突问题 我用的版本: SpringBoot 2.1.4 MybatisPlus 3.1.1 activiti 5.21.0 启动报错 ![图片说明](https://img-ask.csdn.net/upload/201908/28/1566985960_344424.png) 将MybatisPlus版本换成3.1.0和3.1.2都不行 又将activiti版本换成6.0也不行。有没有推荐的

程序员必须掌握的核心算法有哪些?
由于我之前一直强调数据结构以及算法学习的重要性,所以就有一些读者经常问我,数据结构与算法应该要学习到哪个程度呢?,说实话,这个问题我不知道要怎么回答你,主要取决于你想学习到哪些程度,不过针对这个问题,我稍微总结一下我学过的算法知识点,以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的,并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构,当然,我也会整理一些看过...

死磕YOLO系列,YOLOv1 的大脑、躯干和手脚
YOLO 是我非常喜欢的目标检测算法,堪称工业级的目标检测,能够达到实时的要求,它帮我解决了许多实际问题。 这就是 YOLO 的目标检测效果。它定位了图像中物体的位置,当然,也能预测物体的类别。 之前我有写博文介绍过它,但是每次重新读它的论文,我都有新的收获,为此我准备写一个系列的文章来详尽分析它。这是第一篇,从它的起始 YOLOv1 讲起。 YOLOv1 的论文地址:https://www.c...

究竟你适不适合买Mac?
我清晰的记得,刚买的macbook pro回到家,开机后第一件事情,就是上了淘宝网,花了500元钱,找了一个上门维修电脑的师傅,上门给我装了一个windows系统。。。。。。 表砍我。。。 当时买mac的初衷,只是想要个固态硬盘的笔记本,用来运行一些复杂的扑克软件。而看了当时所有的SSD笔记本后,最终决定,还是买个好(xiong)看(da)的。 已经有好几个朋友问我mba怎么样了,所以今天尽量客观
程序员一般通过什么途径接私活?
二哥,你好,我想知道一般程序猿都如何接私活,我也想接,能告诉我一些方法吗? 上面是一个读者“烦不烦”问我的一个问题。其实不止是“烦不烦”,还有很多读者问过我类似这样的问题。 我接的私活不算多,挣到的钱也没有多少,加起来不到 20W。说实话,这个数目说出来我是有点心虚的,毕竟太少了,大家轻喷。但我想,恰好配得上“一般程序员”这个称号啊。毕竟苍蝇再小也是肉,我也算是有经验的人了。 唾弃接私活、做外

Python爬虫精简步骤1 获取数据
爬虫的工作分为四步: 1.获取数据。爬虫程序会根据我们提供的网址,向服务器发起请求,然后返回数据。 2.解析数据。爬虫程序会把服务器返回的数据解析成我们能读懂的格式。 3.提取数据。爬虫程序再从中提取出我们需要的数据。 4.储存数据。爬虫程序把这些有用的数据保存起来,便于你日后的使用和分析。 这一篇的内容就是:获取数据。 首先,我们将会利用一个强大的库——requests来获取数据。 在电脑上安装
作为一个程序员,CPU的这些硬核知识你必须会!
CPU对每个程序员来说,是个既熟悉又陌生的东西? 如果你只知道CPU是中央处理器的话,那可能对你并没有什么用,那么作为程序员的我们,必须要搞懂的就是CPU这家伙是如何运行的,尤其要搞懂它里面的寄存器是怎么一回事,因为这将让你从底层明白程序的运行机制。 随我一起,来好好认识下CPU这货吧 把CPU掰开来看 对于CPU来说,我们首先就要搞明白它是怎么回事,也就是它的内部构造,当然,CPU那么牛的一个东

在家远程办公效率低?那你一定要收好这个「在家办公」神器!
相信大家都已经收到国务院延长春节假期的消息,接下来,在家远程办公可能将会持续一段时间。 但是问题来了。远程办公不是人在电脑前就当坐班了,相反,对于沟通效率,文件协作,以及信息安全都有着极高的要求。有着非常多的挑战,比如: 1在异地互相不见面的会议上,如何提高沟通效率? 2文件之间的来往反馈如何做到及时性?如何保证信息安全? 3如何规划安排每天工作,以及如何进行成果验收? ......
作为一个程序员,内存和磁盘的这些事情,你不得不知道啊!!!
截止目前,我已经分享了如下几篇文章: 一个程序在计算机中是如何运行的?超级干货!!! 作为一个程序员,CPU的这些硬核知识你必须会! 作为一个程序员,内存的这些硬核知识你必须懂! 这些知识可以说是我们之前都不太重视的基础知识,可能大家在上大学的时候都学习过了,但是嘞,当时由于老师讲解的没那么有趣,又加上这些知识本身就比较枯燥,所以嘞,大家当初几乎等于没学。 再说啦,学习这些,也看不出来有什么用啊!
