1.整合Sevlet

1.1 通過註解掃描servlet元件的註冊

1.1.1編寫servlet

package com.cloudtech.servlet;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
 * 測試spring boot註解方式整合HelloServlet
* @ClassName: HelloServlet  
* @Description:   
* @author wude  
* @date 2018年12月7日  
* 
 */
@WebServlet(name="helloServlet",urlPatterns="/do")
public class HelloServlet extends HttpServlet{

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	
	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		System.out.println("helloServlet.....");
		//super.doGet(req, resp);
	}
}
 

1.1.2編寫啟動類

package com.cloudtech;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;

/**
 * springboot啟動類
* @ClassName: App  
* @Description:   
* @author wude  
* @date 2018年12月6日  
*
 */
@SpringBootApplication
@ServletComponentScan  //在spring boot啟動時，會掃描@webServlet,並將該類例項化
public class App {
	public static void main(String[] args) {
		SpringApplication.run(App.class, args);
	}
}
