springboot配置文件:application.properties:
#设置端口号、上下文访问路径
server.port=9002
server.servlet.context-path=/myboot
#设置视图解析器
spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp
创建mian.jsp:

<body>
main.jsp用来显示数据 ${data}

创建控制器：HelloController：
package com.bjpowernode.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class HelloController {
@RequestMapping("/hello")
public ModelAndView hello(){
ModelAndView mv =new ModelAndView();
mv.addObject("data","SpringBoot打jar包");
mv.setViewName("main");//转发到main.jsp
return mv;
}
}
主启动类：Application：启动项目
package com.bjpowernode;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
测试运行：
打jar包：
需要在pom.xml中指定打包名称，和Maven插件：maven-plugin的版本号

先clean，在package：?
?
?打包成功：
打开jar包所在的目录，输入cmd，以命令行的形式运行springboot的应用：
?输入命令
?
可以看到端口号是9002 ，地址myboot：在浏览器运行
?
?
?可以写一个脚本在Linux服务器上运行
?
?
总结：

war和jar区别：
打包成war包：
需要一个服务器，有服务器才能执行，服务器启动的时候需要占用资源，而且还占用端口号，项目是放到服务器里面取的，这种方式是服务器占用比较多，启动tomcat，再启动应用才行，好处是能够充分应用这个服务器的能力，他们是独立的?，能利用tomcat做一些请求和操作
打包成jar包：
比较小巧一点，不依赖服务器，用起来比较简单和方便，不需要做过多的配置，jar包里面有内嵌的tomcat，但是内置的比不上独立的服务器，在某些功能上呢比独立的服务器要弱
