1.建立專案

File->Project->JAVA Eenterprise

勾選Web Application，其它框架按自己需求勾選

然後Next，選擇工程路徑， 點選Finish。

2.配置Tomcat

配置專案訪問根路徑

3.配置部署路徑

4.建立一個測試介面

1.在src目錄下建立ServletTest

@WebServlet(name = "ServletTest")
public class ServletTest extends HttpServlet {
    protected void doPost
 
(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    }

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter writer = response.getWriter();
        writer.write("Hello"
 
);
        writer.close();
    }
}

2.配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
 

         version="3.1">
    <servlet-mapping>
        <servlet-name>ServletTest</servlet-name>
        <url-pattern>/ServletTest</url-pattern>
    </servlet-mapping>
    <servlet>
        <servlet-name>ServletTest</servlet-name>
        <servlet-class>com.gamepp.ServletTest</servlet-class>
    </servlet>
</web-app>

3.啟動tomcat
訪問 http://localhost:8080/Gamepp/ServletTest
成功返回 “Hello”
