Encapsulation of Java multi-thread processing tasks

Encapsulation of Java multi-thread processing tasks

 

Recently, many projects in the company use multiple threads to process some tasks. The logic code and java multi-thread processing code are mixed together, resulting in extremely poor code readability. Now we can extract Java multi-thread-related processing, this is used repeatedly in the aspect code. You are welcome to make a picture.

It is easy to use. There are two ways to use it.

1. directly pass a batch of tasks to the multi-thread processing method and return the processing results

The Code is as follows:

 
 

  
  
/**
  
  
* Created with IntelliJ IDEA.
  
  
* Testing multi-thread processing tasks
  
  
* ClassName: TaskMulThreadServiceTest
  
  
*
  
  
* @ Version 1.0
  
  
* Date Time:
  
  
* @ Author: ddys
  
  
*/
  
  
Public class TaskMulThreadServiceTest extends TestCase implements ITaskHandle <String, Boolean> {
  
  
 
  
  
Public void testExecute () throws Exception {
  
  
String [] taskItems = new String [100];
  
  
For (int I = 0; I <100; I ++ ){
  
  
TaskItems [I] = "task" + I;
  
  
}
  
  
IMulThreadService <String, Boolean> mulThreadService = new TaskMulThreadService (this );
  
  
Long start = System. currentTimeMillis ();
  
  
List <Boolean> result = mulThreadService.exe cute (taskItems );
  
  
For (Boolean e: result ){
  
  
If (! E ){
  
  
System. out. println ("task processing failed ");
  
  
}
  
  
}
  
  
System. out. println ("all tasks are processed, time consumed" + (System. currentTimeMillis ()-start) + ", number of successful tasks" + result. size ());
  
  
}
  
  
 
  
  
/**
  
  
* Created with IntelliJ IDEA.
  
  
* Execute the task and return all execution results
  
  
* ClassName: TaskMulThreadService
  
  
*
  
  
* @ Author: ddys
  
  
* @ Version 1.0
  
  
* Date Time:
  
  
*/
  
  
Public Boolean execute (String s ){
  
  
System. out. println (Thread. currentThread (). getId () + "the Thread is processing" + s );
  
  
Return true;
  
  
}
  
  
}
 
 

2. A Query Task method is included to implement the Query Task method and business processing method, and then execute and return the processing result.

The Code is as follows:

Public class SelectTaskMulThreadServiceTest extends TestCase implements ISelectTask <String, Boolean> {
  
  
 
  
  
Public void testExecute () throws Exception {
  
  
IMulThreadService <String, Boolean> mulThreadService = new SelectTaskMulThreadService (this );
  
  
Long start = System. currentTimeMillis ();
  
  
List <Boolean> result = mulThreadService.exe cute ();
  
  
For (Boolean e: result ){
  
  
If (! E ){
  
  
System. out. println ("task processing failed ");
  
  
}
  
  
}
  
  
System. out. println ("all tasks are processed, time consumed" + (System. currentTimeMillis ()-start) + ", number of successful tasks" + result. size ());
  
  
}
  
  
/**

*/
  
  
Public Boolean execute (String s ){
  
  
System. out. println (Thread. currentThread (). getId () + "the Thread is processing" + s );
  
  
Return true;
  
  
}
  
  
 
  
  
/**
  
  
* @ Param 'a pass the Parameter
  
  
* @ Return a return type
  
  
* @ Throws

Public String [] getTaskItem (){
  
  
String [] taskItems = new String [100];
  
  
For (int I = 0; I <100; I ++ ){
