spring configured thread pool

Why 80% of the code can not do farming architect? >>>  

 

spring provides support thread pool

View basic Java thread pool

 

First, a thread ThreadTransCode.java

package com.enorth.lichen.transcode;

public class ThreadTransCode implements Runnable{ 
    
  @Override
   public void run() {
    System.out.println( "转码开始.............."); 
  }
}

 

Add thread pool configuration information in the spring configuration file

< bean id ="taskExecutor"
     class ="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor" >
     < property name ="corePoolSize" value ="3" />
     < property name ="keepAliveSeconds" value ="200" />
     < property name ="maxPoolSize" value ="5" />
     < property name ="queueCapacity" value ="25" />
   </ bean >

 

Add injected in action

< bean id ="saveVideoAction"
       class ="com.enorth.lichen.action.video.SaveVideoAction"
       scope ="prototype" >
       < property name ="videoService" >
         < ref bean ="videoService" />
       </ property >
       < property name ="groupService" >
         < ref bean ="groupService" />
       </ property >
       <property name="taskExecutor">
        <ref bean="taskExecutor" />
      </property>
     </ bean >

 

Call in the action

private TaskExecutor taskExecutor;    

public TaskExecutor getTaskExecutor() {    
         return taskExecutor;    
    }    

public void setTaskExecutor(TaskExecutor taskExecutor) {    
         this.taskExecutor = taskExecutor;    
    }    

public String execute() throws Exception {

for( int k = 0; k < 2; k++) {    
        taskExecutor.execute( new ThreadTransCode());    
    }
return SUCCESS;
}

 

Above can be achieved by using a spring java thread pool ...

Unfortunately, when I use threads in the thread pool to perform transcoding flv, and found that only stopped tomcat can perform automated transcoding operations, other simple multi-threaded operation are possible. The reason is unknown, thread too do transcoding consumption of resources?

 

 

May day. Solved the problem. The reason is that a deadlock ... the actual thread transcoding stopped after tomcat will automatically run already explained, I did not even pay attention to day ...

Thread Pool ThreadPool.java

   public static ExecutorService exec = Executors.newFixedThreadPool(1);
    
   public static synchronized void trans(String videoPath,String targetPath){
    ThreadTransCode trans= new ThreadTransCode(videoPath,targetPath);
    exec.execute(trans);
  }
