servlet

1.实现httpservlet

@WebServlet("/some")
public class SomeServlet extends HttpServlet {

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.getWriter().print("some Servlet");
    }
}

2.

@SpringBootApplication
@ServletComponentScan("com.abc.servlet")  // 指定要扫描Servlet的包
public class Application {

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

}

----------------------------------------------------------------------------------------------------------------------------

　　　　　　　　　　2.5

public class SomeServlet extends HttpServlet {

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.getWriter().print("some Servlet");
    }
}

在配置类中写

@SpringBootApplication
public class Application {

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

    // 基于JavaConfig方式：适用于Servlet2.5+
    // 基于注解方式：适用于Servlet3.0+
    @Bean
    public ServletRegistrationBean<SomeServlet> getServlet() {
        return new ServletRegistrationBean<>(new SomeServlet(), "/some");
    }

}
