哥们 给讲讲 ()里加do Post

Answer 2

request对象在哪里，这个变量从哪里来的，怎么能这样使用

Answer 3

request对象没有定义当然报错.
试试:
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
public class CountService {
private HttpServletRequest request;public HttpServletRequest getRequest() {
return request;
} public void setRequest(HttpServletRequest request) {
this.request = request;
}public int count(){HttpSession session = request.getSession();
}
}
