用javabean在JSP页面中实现进度条效果
public class TaskBean extends Thread{
public TaskBean(){
}
private int percent=0;
private boolean complete=false;
public synchronized void run() {
while(true){
if(percent>=100){
complete=true;
return;
}
try {
Thread.sleep(1000);
} catch (Exception e) {
System.err.println("TaskBean.run()"+e.getMessage());
}
percent+=10;
}
}
public boolean isComplete(){
return complete;
}
public int getPercent(){
return percent;
}
}
