简单的线程池实现多线程对大文件的读取 php

上代码
package ThreadLearning;
【简单的线程池实现多线程对大文件的读取】import java.io.*;
import java.util.ArrayList;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
/**

public class LstFileAnalysis {

static String fileUrl = ""; static File file = new File(fileUrl); static InputStreamReader isr; static { try { isr = new InputStreamReader(new FileInputStream(file)); } catch (FileNotFoundException e) { e.printStackTrace(); } }public static void main(String[] args) throws IOException { ExecutorService executorService = Executors.newFixedThreadPool(4); BufferedReader read = new BufferedReader(isr); String line = ""; long l = System.currentTimeMillis(); while ((line = read.readLine()) != null) { String[] split = line.split("\s+"); if (split.length == 0) { break; } Runnable task = new Task(line); executorService.execute(task); } long l1 = System.currentTimeMillis(); System.out.println((l1 - l)); }

}
复制代码
Task类提供一个简单的思路： 1、读取出来的数据处理过后存入数据库[写在run方法里就行]
package ThreadLearning;
import java.util.List;
/**

@author kyojurorengoku

@Description
*/

public class Task implements Runnable {

private String line; public Task(String line) { this.line = line; }@Override public void run() {

// System.err.println(Thread.currentThread().getName() + " " + line);

}

}
