In jbpm4, you can use the following methods to obtain the tasks to be processed by the specified user:
Processengine. gettaskservice (). findpersonaltasks (User ID); // obtain the personal task processengine. gettaskservice (). findgrouptasks (User ID); // obtain the group task

First, Introduction1, multi-task processingWhat is multi-tasking? It means that when the app is suspended, it can still do some developer-defined tasks, such as updating tiles and toasts, scheduled toast and reminders, background tasks, and so on.2. Background tasksThe app can register a background task, it is run and managed by the system, but it still uses the same data storage as the foreground program,
Scheduled Tasks in LinuxExecutes the specified task within the agreed time, called a scheduled task.There are generally two ways to schedule tasks in Linux:Scheduled Tasks and recurring scheduled tasks that are performed at onceOne-time scheduled tasks, using command ata at:

You can use Postgresql's pgAgent to create scheduled tasks to conveniently create scheduled tasks. Currently, the online materials are relatively old, And the Postgresql version is updated faster, resulting in some online tutorials being useless. Now I want to share my experience.

I. Tasks and ThreadsThe specific distinction between threads and tasks in a single section of thinking in Java also shows that tasks and threads are different.As mentioned above, the task is just a piece of code, a piece of code to achieve your purpose, where this code is written, how to write it does not matter, just because you want Java's multithreading mechan
Notes [Java7 Concurrent Programming manual] series catalogueBrief introductionOne of the advantages of the execution Framework (Executor framework) is that you can return results when running concurrent tasks. However, the following two classes are required to implement the functionality: 1. InterfaceCallable
A task that returns the result and may throw an exception. The implementing person defines a method called call without any parameter
As title shows, sometimes we need to configure simple scheduled tasks in a Web project, and because the tasks are not complex and do not want to use a scheduled scheduling framework (Ps:quartz, ActiveMQ, Kafka, etc.), consider using @scheduled annotations to define simple scheduled tasks. Its full configuration is as follows:(1) Add the timing task related config
Most of the analysis results show that some tasks of the project have unreasonable logic in allocation and work hours, leading to exceptions in the webpart. Usually, the PWA System maintenance staff will be crazy at this time, because no one changes the settings, the server services are normal, and this logical error occurs inadvertently under the project manager. I felt that the last second was still good, and suddenly I got down. (For administrators
