学习了如何在网页中显示动态数据。通过 Java 代码向 JSP 页面传递一个字符串变量，在页面中显示出来。
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;

public class DynamicDataServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String message = "Hello from JavaWeb on day 3!";
request.setAttribute("data", message);
request.getRequestDispatcher("result.jsp").forward(request, response);
}
}
