一、POM.XML

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

  <parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.4.1.RELEASE</version>
	</parent>
	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<!-- 指定一下jdk的版本 ，這裏我們使用jdk 1.8 ,默認是1.6 -->
		<java.version>1.8</java.version>
	</properties>
	<dependencies>
		<!-- 添加fastjson 依賴包. -->
		<dependency>
			<groupId>com.alibaba</groupId>

		</dependency>
		<!-- spring-boot-starter-web: MVC,AOP的依賴包.... -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
			<!-- <version></version> 由於我們在上面指定了 parent(spring boot) -->

	<build>
		<finalName>springboot_servlet_15</finalName>
		<plugins>
			<!-- 這是spring boot devtool plugin (推薦) -->
			<!--fork : 如果沒有該項配置，肯呢個devtools不會起作用，即應用不會restart -->

</project>

二、APP.java

package com.fs;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;

@SpringBootApplication
public class App {

    @Bean
    public ServletRegistrationBean myServlet1() {
        return new ServletRegistrationBean(new MyServlet1(), "/myServlet1");
    }

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

三、MyServlet1

package com.fs;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Servlet implementation class MyServlet1
 */
public class MyServlet1 extends HttpServlet {
	private static final long serialVersionUID = 1L;
       
    /**
     * @see HttpServlet#HttpServlet()
     */
    public MyServlet1() {
        super();
        // TODO Auto-generated constructor stub
    }

	/**
	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		response.getWriter().append("Served at: ").append(request.getContextPath());
	}

	/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		doGet(request, response);
	}

}
