Activiti 5.12发布

1. 5.12版本重要改变

  1. 在Activiti Explorer中添加了基于Javascript的流程图查看功能,由Raphaël提供画图支持,支持全部浏览器;这个功能是我在5.11版本发布之后提出的,后来Tijs说让我帮忙做一个,最后用jQuery实现了(和kft-activiti-demo里面的跟踪效果一样,后来tijs告诉我有人在做了,所以我就取消了这个任务),效果图在下面。
  2. 统一了BPMN解析,可以应用于引擎、Activiti Designer、Activiti Modeler。
  3. 添加Activiti Kickstar到Activiti Explorer,让不懂BPMN规范的人也可以设计简单流程(设计的流程都是顺序流,设计的时候不要在assignee<办理人>字段填写值,否则会报错)。
  4. 简化并扩充了Activiti Camel模块。
  5. 在Activiti Explorer中添加了报表功能,可以以用户、任务、流程等维度生成图形报表。
  6. 添加auto-layout模块,可以应用与KickStart和Modeler(还未验证)。
  7. 添加了针对Script Task的Execution监听解析。
  8. 支持流程定义缓存,可以减少数据库读取。
  9. 一些其他的Bug修复。

3. 值得关注的重要Bug及新功能

  1. 移除了org.activiti.engine.impl.bpmn.parser.BpmnParseListener以及相关类,取而代之的是在引擎中配置实现监听器触发方式,在用户手册的第17章有详细介绍。
  2. 在5.11版本中最严重的一个Bug应该属于ACT-1528,当删除一个流程实例时这个Bug会导致整个ACT_HI_VARINST表被清空!!! 如果使用5.11的建议升级到5.12,或者自己打补丁。
  3. 自动生成的图片导致中文乱码,这个问题在5.12里面我已经彻底解决了,解决办法是在引擎里面配置属性activityFontName,配置成中文字体的文件名就可以了。
  4. 支持终止结束事件。
  5. Native Query是在5.11版本中添加的,很好的解决了固定API查询不够灵活的问题,但是不支持分页查询,只能自己在sql中添加分页语句与参数;在5.12版本发布之前我提交了支持分页查询的代码,代码也合并到了master分支,但是在发布之前又还原了(因为不支持db2与sqlserver分页),我又紧急修复提交,可惜最终没有合并到5.12中,不过5.12发布之后我发布了5.12.1版本用于弥补这一遗憾(后面公布地址)。

4. 我的Activiti分支5.12.1
