使用线程池时如何给入参数

Question

@Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String param = request.getParameter("param");//获取发送的参数 String content = request.getParameter("content");//获取发送的参数 ExecutorService threadPool = Executors.newFixedThreadPool(5);//定义长度为5的线程池 threadPool .execute(new Runnable(){ @Override public void run() { //在此处如何获取request对象 //如何获取param参数 //如何获取content参数 //逻辑代码,数据库操作 } }); }

Answer 1

简单封装下即可，比例param参数

public class MyTask implements Runnable{

    private String param;

    public MyTask(String param){
        this.param = param;
    }
    
    @Override
    public void run() {
        ......
    }
}

//在doGet()中
MyTask task = new MyTask(param);
threadPool .execute(task);
