使用原生HttpServlet来提高压测性能

压测hello world的时候，发现spring mvc比HttpServlet的性能下降20%作用
在spring boot环境下使用HttpServlet如下

1、添加@ServletComponentScan 注解

@ServletComponentScan 
@SpringBootApplication
public class HelloK8sApp {
    public static void main(String[] args) {
        SpringApplication.run(HelloK8sApp.class);
    }
}

2、使用@WebServlet 注解HttpServlet类

@WebServlet(value = "/xyz")
public class HelloServlet extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) 
	throws ServletException, IOException {
        resp.getOutputStream().write("xyz".getBytes(StandardCharsets.UTF_8));
    }
}
