servlet的请求方式

测试servlet的请求方式默认是get请求方式：

1.新建一个GetAndPost的测试类，代码如下：

package eduask;
 import java.io.IOException;
 import javax.servlet.ServletException;
 import javax.servlet.http.HttpServlet;
 import javax.servlet.http.HttpServletRequest;
 import javax.servlet.http.HttpServletResponse;
 //测试默认的请求方式为get请求方式;
 public class GetAndPost extends HttpServlet{
 @Override
 protected void doGet(HttpServletRequest req, HttpServletResponse resp)throws ServletException, IOException {
 System.out.println("doGet");
 }
 protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException ,IOException {
 System.out.println("doPost");
 }
 }

2.在web.xml文件中配置相关属性，配置结果如下：

<!--测试get和post的请求方式  -->
 <servlet>
 <servlet-name>getAndPost</servlet-name>
 <servlet-class>eduask.GetAndPost</servlet-class>
 </servlet>
 <servlet-mapping>
 <servlet-name>getAndPost</servlet-name>
 <url-pattern>/getAndPost</url-pattern>
 </servlet-mapping>

3.启动tomcat在浏览器中输入：

​​http://localhost:8080/webDemo/getAndPost​​

4.在控制台下可以看到“doGet”
