Abstract

The invention discloses a task scheduling method and device, and relates to the technical field of computers. The method comprises the steps of reading task configuration information from a database,and assembling a task according to the task configuration information; triggering the task at regular time through a timer; and when the task is triggered regularly, sending a task execution instruction to a client node through long connection, so that the client node executes the task. Through the above steps, when task scheduling is carried out, the application server does not need to depend onQuartz, Crontable and other third-party components, and the problems that in existing task scheduling depending on the third-party components, the performance of the application server is reduced, andheterogeneous system compatibility is poor are effectively solved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a task scheduling method and device. Background technique [0002] In the prior art, Java scheduled task scheduling solutions are generally implemented based on Quartz (an open source job scheduling framework written in Java) or Scheduler (thread pool). In addition, calling the JNI interface (JNI is the abbreviation of Java Native Interface, which provides several APIs to realize the communication between Java and other languages) through the Crontable component of the Linux system can also implement scheduled task scheduling. [0003] Third-party components such as Quartz and Crontable are often used for stand-alone task scheduling. That is to say, a Quartz or Crontable component needs to be separately deployed on each machine (such as an application server) to support task scheduling of native services. In addition, Quartz officially provides Quartz's cluster deploy...
