下文笔者将讲述两种SpringBoot集成Servlet的方法，如下所示:

实现思路:
方式1：
使用全注解的方式开发
1.1 在启动类上面加上注解 @ServletComponentScan
1.2 编写Servlet程序，并在Servlet程序上加上注解 @WebServlet(name="testServlet1",urlPatterns = "/test")
方式2:
直接编写一个@Configuration类
将Servlet程序使用ServletRegistrationBean注册到Springboot中
例1:
 

//启动类上加入Servlet扫描注解
@SpringBootApplication
@ServletComponentScan
public class SpringbootservletApplication { public static void main(String[] args) { SpringApplication.run(SpringbootservletApplication.class, args); } } //编写Servlet类 @WebServlet(name="testServlet1",urlPatterns = "/test") public class TestServlet extends HttpServlet { @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { System.out.println("java265.com 提醒你 -servlet已经开始运行"); } } -----采用以上方式编写代码后，我们可以使用 http://localhost:8080/test访问servlet了

---

例2:

 

@SpringBootApplication
public class SpringbootservletApplication { public static void main(String[] args) { SpringApplication.run(SpringbootservletApplication.class, args); } } //编写servlet public class TestServlet extends HttpServlet { @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { System.out.println("java265.com 提醒你 -servlet已经开始运行"); } } //编写configuration类 package com.java265; import com.adeal.servlet.TestServlet; import org.springframework.boot.web.servlet.ServletRegistrationBean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; @Configuration public class ServletConfig { /* * 多个Servlet 需实例化多个ServletRegistrationBean实例 * */ @Bean public ServletRegistrationBean getServletRegistrationBean() { ServletRegistrationBean bean = new ServletRegistrationBean(new TestServlet()); //Servlet既可以使用 test01也可以使用test02访问 bean.addUrlMappings("/test02"); bean.addUrlMappings("/test01"); return bean; } } -------编写以上代码后，我们可以使用---- http://localhost:8080/test01 访问servlet了 http://localhost:8080/test02 访问servlet了
