Question

简单程序中@WebServlet("/HelloWorld")报错 问题在哪里?

package 简单的servlet例子;

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.*;

//设置访问或者调用这个Servlet的路径
@WebServlet("/HelloWorld")

public class HelloWorldServlet extends HttpServlet{
// 处理HTTpget类型的请求

protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException ,IOException{
// 让输出的页面支持中文
response.setContentType("text/html; charset=utf-8");
// 获得输出对象
PrintWriter out = response.getWriter();
// 向请求输出信息
out.println("HelloWorld . It is a HelloWorldServlet!!."+"<br>");
}

}

Answer 1

你试试这种写法呢，@WebServlet(name="helloWorldServlet",urlPatterns="/helloWorldServlet")
