首先创建项目:
首先创建项目:
- 填写组织名称跟war包名称
- 选择本地maven仓库
- 填写项目名称跟选址项目储存位置,点击finish即可成功创建项目
- 项目创建成功
如果没有以上项目列表可以等一会或者按一下步骤抄作
- 创建项目需要的文件夹
使文件夹变成系统可读文件夹:
选择后:
在java中创建对应包
- 配置pom.xml,导入需要的jar包
//在pom文件中找到这个标签,配置所需要的jar包
//里面每一个配置一个jar包
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>
</dependencies>
所需要的jar都在mvn中查找:https://mvnrepository.com/
你需要什么jar包直接搜索就可以了
例如我需要连接数据库的jar,直接搜索mysql
按照上面的配置方法你可以将你需要的jar包全部配置好,配置完成后点击idea右上角的maven中的刷新按钮即可将jar包引入进来
- 配置完pom.xml之后配置web.xml
