<servlet>
            <servlet-name>test</servlet-name>
            <servlet-class>xuan.ServletTest</servlet-class>
        </servlet>
        
        <servlet-mapping>
            <servlet-name>test</servlet-name>
            <url-pattern>/xiaoxuan</url-pattern>
        </servlet-mapping>

package xuan;
    
    import javax.servlet.ServletException;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.io.IOException;
    
    /**
     * @author Xuan
     * @date 2019/9/6 14:43
     */
    public class ServletTest extends HttpServlet {
        @Override
        protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
            doPost(req, resp);
        }
    
        @Override
        protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
            //设置响应的字符集为UTF-8
            resp.setContentType("text/html;charset=UTF-8");
            resp.getWriter().println("测试Servlet页面");
        }
    }

#### 5、启动Tomcat并且访问映射的路径（这里的是/xiaoxuan） ####
