maven依赖坐标实现

1.在pom.xml编写<dependencies>标签

2.在此标签中使用<dependency>引入坐标

3.定义坐标的groupld，artifactld，version

4.点击刷新按钮，是坐标生效

 <dependencies>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.25</version>
    </dependency>
    </dependencies>

如果找不到mysql代码编号，则登入Maven Repository: mysql » mysql-connector-java (mvnrepository.com)此网址，寻找一个mysql编号并复制期中代码

遇见此类

Dependency 'mysql:mysql-connector-java:8.0.25' not found

报错，则点击此处刷新maven

 以上会出现依赖坐标。
