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);
