谈谈 Idea编辑器和SpringBoot轻量框架 初级开发者如何让其启动和访问

刚来XX公司，项目需要用到SpringBoot，编辑器也想统一，结果：一.经过官网下载，注册邮箱，Idea下好安装了。二.SpringBoot放在idea内就是一个坑，基本路线搭建好，如下排查：   1.JDK版本保证1.8及以上。 检查环境是否配置好了。按照网上的步骤给idea加JDK1.8版本   2.Tomcat是否是7以上，最好也是8。       里面的端口号尽量提前改掉别以后用到再改就坑了。改完的端口号一定要都记到例如 电脑上的txt文件内，进行标注。重点：改端口号例如：8099   3.当按照网上一般Maven+SpringBoot在Idea内弄好后，没启动成功怎么整。看看下面这个图，设置内置Tomcat启动的端口号，原默认都是8080

    resources下的application.properties文件中添加顶行加server.port=8099

4.包的问题，包的依赖关系很强，你要测试或用到，再看这图(看清楚那选中的玩意儿)，若少了那个试试能启动成功才怪，因为在main入口那边我是这么用的：

ackage com.example.demo;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
@EnableAutoConfiguration
@RestController
public class HelloController {
@RequestMapping("/")
@ResponseBody
public String say(){
return "Hello Java!";
}
}

这是main入口

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

public static void main(String[] args) {
SpringApplication.run(HelloController.class, args);
System.out.println("成功搭建");
}
}

5.最后附上我的pom.xml那些基本依赖包供各位参考：

<groupId>com.example</groupId>

成功启动就这样简单~
