1　　　　主要内容

1.1　　pom.xml的基本结构

a　　parent标签加入springboot，标识springboot项目（引入springboot依赖）

b　　添加maven坐标，标识maven项目

c　　dependency标签引入其它依赖

d　　build引入其他插件

 

2　　　　个人收获

2.1　　pom中右键没有maven选项后如何处理

原因是右键pom.xml,-->maven-->remove projects

解决方法，右键add as mavenproject

 

3　　　　课程内容

3.1　　demo

a　　新建maven项目

 

b　　修改pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<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/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <!-- 1  引入springboot -->

            </plugin>
        </plugins>
    </build>
    
</project>

 

c　　编写顶类

package com.imooc.springboot.application;

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

/**
 * SpringBootApplication
 *
 * @author 魏豆豆
 * @date 2021/1/13
 */
@SpringBootApplication
public class SpringBootStudyApplication {
    public static void main(String [] args){
        SpringApplication.run(SpringBootStudyApplication.class,args);

    }
}

 

d　　运行main函数
