java 接受http请求

Posted 2023-03-09

在Spring MVC中是用
@ResponseBody

@RequestMapping("/student/list")
public MessageJson<List<Student>> list()

这个就能接收到http请求，但如果不用Spring MVC的话，如何写才能接收到http请求，我只想写一个最简单的，初学java

使用servlet

public class Test extends HttpServlet

private static final long serialVersionUID = 1L;

       

    /**

     * @see HttpServlet#HttpServlet()

     */

    public Test()

        super();

        // TODO Auto-generated constructor stub

   

/**

* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)

*/

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException //接收get请求

// 这里写你接收request请求后要处理的操作

/**

* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)

*/

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException //接收post请求

// 这里写你接收request请求后要处理的操作

追问

那我在网页上怎么访问
我的项目是aaa,
localhost:8080/aaa/doGet 这样子不行，要怎么写才可以啊

参考技术A 需要在web.xml中进行配置，如下：
<servlet>
<servlet-name>LoginServlet</servlet-name>
<servlet-class>com.pb.servlet.LoginServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>LoginServlet</servlet-name>
<url-pattern>/*（需要拦截的路径）</url-pattern>
</servlet-mapping>
如果用类似Myeclipse的工具新建servlet，它会自动跟你设置好 参考技术B 去看看servlet吧
