SpringBoot中使用Servlet

1.在入口Application类上加入注解@ServletComponentScan

@SpringBootApplication
@ServletComponentScan
public class UseServletInSpringbootApplication {

    public static void main(String[] args) {
        SpringApplication.run(UseServletInSpringbootApplication.class, args);
    }
}

2.新建Servlet类，继承HttpServlet并且加入注解 @WebServlet(name="TestServlet",urlPatterns="/test")

@WebServlet(name="TestServlet",urlPatterns="/test")
public class TestServlet extends HttpServlet
{
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException
    {
        System.out.println("doGet");
    }
}

3.之后运行代码，在地址栏输入 http://localhost:8080/test，若看到控制台打印doGet，则表示Servlet创建成功。
