Task processing method, device, equipment and medium of java thread pool

Abstract

The present application relates to a task processing method, device, computer equipment and storage medium of a Java thread pool. The method includes: when the target task is received, judging whether the thread pool is full; the target task is a task in a preset task set; if the thread pool is full, according to the target value of the number of buffer queues corresponding to the thread pool, The target number of threads corresponding to the thread pool and the minimum task time consumption corresponding to the task set determine the waiting time required to execute the target task; where the minimum task time consumption is the minimum value of the task time consumption of each task corresponding to the task set; When the waiting time is up, the control main thread adds the target task to the thread pool. This method can avoid the waste of resources caused by the main thread executing tasks being blocked for too long and the threads in the thread pool being in an idle state.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a task processing method, device, computer equipment and storage medium of a Java thread pool. Background technique [0002] Creating and destroying threads in Java consumes a lot of time and resources. Therefore, in the case of multi-tasking, we will choose to use thread pool technology to cache the created threads and execute them directly when new tasks arrive without renewing them. Create threads. Usually, when a new task is added to the thread pool, if there is no idle worker thread in the thread pool and the buffer queue is full, it will be judged whether the number of threads in the thread pool has reached the maximum number of threads, if not, Then start a new thread to execute the task. If the maximum number of threads has been reached, these tasks will be processed through the corresponding rejection policy. [0003] In traditional technology, the co...

Problems solved by technology

[0003] In traditional technology, the commonly used rejection strategy is the caller-run strategy. In the case of using this rejection strategy, when the thread pool reaches the maximum number of threads and the buffer queue is full, the main thread executes the task, and then When a new task comes, even if other threads are already idle, but because the main thread is executing tasks and is in a busy state, new tasks cannot be assigned to the current thread pool

[0004] Therefore, the execution method of the traditional Java thread pool rejection strategy has the problem of waste of resources
