eclipse搭建servlet項目

1、創建web項目

2、勾選Generate web.xml

3、創建Class文件並實現Servlet接口

當搜索Servlet接口時，如果未發現接口則Add library→選擇tomcat版本至完成。

代碼如下：

 
 
 
         

  
  
  
          
package test.servlet;
  
  
  
          

  
  
  
          
import java.io.IOException;
  
  
  
          

  
  
  
          
import javax.servlet.Servlet;
  
  
  
          
import javax.servlet.ServletConfig;
  
  
  
          
import javax.servlet.ServletException;
  
  
  
          
import javax.servlet.ServletRequest;
  
  
  
          
import javax.servlet.ServletResponse;
  
  
  
          

  
  
  
          
public class TestServlet implements Servlet {
  
  
  
          

  
  
  
          
 @Override
  
  
  
          
 public void destroy() {
  
  
  
          
 // TODO Auto-generated method stub
  
  
  
          

  
  
  
          
 }
  
  
  
          

  
  
  
          
 @Override
  
  
  
          
 public ServletConfig getServletConfig() {
  
  
  
          
 // TODO Auto-generated method stub
  
  
  
          
 return null;
  
  
  
          
 }
  
  
  
          

  
  
  
          
 @Override
  
  
  
          
 public String getServletInfo() {
  
  
  
          
 // TODO Auto-generated method stub
  
  
  
          
 return null;
  
  
  
          
 }
  
  
  
          

  
  
  
          
 @Override
  
  
  
          
 public void init(ServletConfig arg0) throws ServletException {
  
  
  
          
 System.out.println("servlet初始化");
  
  
  
          

  
  
  
          
 }
  
  
  
          

  
  
  
          
 @Override
  
  
  
          
 public void service(ServletRequest arg0, ServletResponse arg1) throws ServletException, IOException {
  
  
  
          
 System.out.println("service");
  
  
  
          

  
  
  
          
 }
  
  
  
          
 public TestServlet(){
  
  
  
          
 System.out.println("TestServlet");
  
  
  
          
 }
  
  
  
          

  
  
  
          
}
 
 
 
         

4、編輯web.xml文件：

 
 
 
         

  
  
  
          
<?xml version="1.0" encoding="UTF-8"?>
  
  
  
          
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  
  
  
          
 xmlns="http://java.sun.com/xml/ns/javaee"
  
  
  
          
 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
  
  
  
          
 id="WebApp_ID" version="3.0">
  
  
  
          
 <display-name>servlet-demo</display-name>
  
  
  
          
 <welcome-file-list>
  
  
  
          
 <welcome-file>index.html</welcome-file>
  
  
  
          
 <welcome-file>index.htm</welcome-file>
  
  
  
          
 <welcome-file>index.jsp</welcome-file>
  
  
  
          
 <welcome-file>default.html</welcome-file>
  
  
  
          
 <welcome-file>default.htm</welcome-file>
  
  
  
          
 <welcome-file>default.jsp</welcome-file>
  
  
  
          
 </welcome-file-list>
  
  
  
          
 <!-- 配置和映射servlet -->
  
  
  
          
 <servlet>
  
  
  
          
 <!-- Servlet注冊的名字 -->
  
  
  
          
 <servlet-name>TestServlet</servlet-name>
  
  
  
          
 <!-- Servlet的全類名 -->
  
  
  
          
 <servlet-class>test.servlet.TestServlet</servlet-class>
  
  
  
          
 </servlet>
  
  
  
          
 <servlet-mapping>
  
  
  
          
 <!-- 需要和某一個servlet節點的servlet-name子節點的名稱一致 -->
  
  
  
          
 <servlet-name>TestServlet</servlet-name>
  
  
  
          
 <!-- 映射具體的訪問路徑：/代表當前web應用的根目錄 -->
  
  
  
          
 <url-pattern>/TestServlet</url-pattern>
  
  
  
          
 </servlet-mapping>
  
  
  
          
</web-app>
