SpringBoot整合Servlet的两种方式

Maven3.5 JDK1.8 idea SpringBoot2.0.1

工程pom文件加入Jar包

    <dependency>         <groupId>org.springframework.boot</groupId>         <artifactId>spring-boot-starter-web</artifactId>     </dependency>

@WebServlet(name = "firstServlet", urlPatterns = "/firstServlet")  //标记为servlet，以便启动器扫描。 public class FirstServlet extends HttpServlet {      @Override     protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {         resp.getWriter().append("firstServlet");     }  }

@SpringBootApplication @ServletComponentScan   //启动器启动时，扫描本目录以及子目录带有的webservlet注解的 public class FirstServletApplication {      public static void main(String[] args) {         SpringApplication.run(FirstServletApplication.class, args);     } }

//这里不需要添加webServlet注解 public class SecondServlet extends HttpServlet {     @Override     protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {         resp.getWriter().append("SecondServlet");}}

@SpringBootApplication public class SecondServletApplication {     public static void main(String[] args) {         SpringApplication.run(SecondServletApplication.class, args);     }     @Bean  //一定要加，不然这个方法不会运行     public ServletRegistrationBean getServletRegistrationBean() {  //一定要返回ServletRegistrationBean         ServletRegistrationBean bean = new ServletRegistrationBean(new SecondServlet());     //放入自己的Servlet对象实例         bean.addUrlMappings("/secondServlet");  //访问路径值         return bean;}}
