亲爱的 stackoverflow 成员(member)，
到目前为止我已经做了什么:
我从我的 eclipse 创建 apache tomcat 服务器
我也成功地在 .html 文件中运行简单的“hello world”
问题是当我运行一个 servlet 时它显示错误
HTTP Status 404 - /SimpleServletProject/SimpleServlet
type Status report
message /SimpleServletProject/SimpleServlet
description The requested resource is not available.
Apache Tomcat/7.0.42
下面是我的servlet
package com.bukuwow.azura;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
* Servlet implementation class SimpleServlet
*/
@WebServlet(description = "a simple servlet", urlPatterns = { "/SimpleServlet" })
public class SimpleServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
System.out.println("Hello from servlet");
}
}
这是我的项目结构
