Servlet代码编写

在学习过程中使用MyEclipse2016，根据学习资料的学习过程发现编写的Servlet在调用是会出问题，经过测试发现MyEclipse2016可一在建servlet类时自动关联web.xml配置文件具体使用方法如下：

1. 新建文件选servlet类，输入类名后点击next

新建servlet 自动生成web.xml

选择后系统会自动生成关联，自动生成示文件内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <servlet>
    <servlet-name>Myservlet</servlet-name>
    <servlet-class>servlet1.Myservlet</servlet-class>
  </servlet>
  <servlet>
    <servlet-name>testServlet</servlet-name>
    <servlet-class>servlet1.testServlet</servlet-class>
  </servlet>


  <servlet-mapping>
    <servlet-name>Myservlet</servlet-name>
    <url-pattern>/servlet/Myservlet</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>testServlet</servlet-name>
    <url-pattern>/testServlet</url-pattern>
  </servlet-mapping>

</web-app>

编写测试Servlet类如下：
测试代码

package servlet1;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.Date;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class Myservlet extends HttpServlet {

    
    public Myservlet() {
        super();
    }

    
    public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
          response.getWriter().write("now time:" + new Date());
    }

    
    public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    this.doGet(request, response);
    }

}

使用刚才配置文件配置方式

运行结果
