方法一
- 创建一个Servlet类并加上
@WebServlet
@WebServlet("/student")
public class StudentServlet extends HttpServlet {
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
resp.getWriter().println("hello student servlet!");
}
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
this.doPost(req, resp);
}
}
- 在springBoot启动类上添加
@ServletComponentScan("servlet包路径")
@SpringBootApplication
@ServletComponentScan("com.hzc.servlet")
public class SpringBoot07Application {
public static void main(String[] args) {
SpringApplication.run(SpringBoot07Application.class, args);
}
}
方式二
- 创建一个Servlet类,不添加注解
public class UserServlet extends HttpServlet {
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
resp.getWriter().write("hello user servlet!");
}
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
this.doPost(req, resp);
}
}
- 创建Servlet核心配置类,注册servlet.注意
@Bean
和返回一个ServletRegistrationBean
@Configuration
public class ServletConfig {
@Bean
public ServletRegistrationBean servletRegistrationBean(){
ServletRegistrationBean<UserServlet> userServlet = new ServletRegistrationBean<>(new UserServlet(), "/user");
return userServlet;
}
}
