品牌信息管理系统的后台管理(javaweb+vue+mybatis+tomcat+maven)
本系统主要针对于初学javaweb的博友们，拿来练手的。

本系统主要针对于初学javaweb的博友们，拿来练手的。
由于本系统是后台管理所以没有注册功能，需要的博友们可以自行添加。我会把这个系统的源代码的百度网盘链接放到评论下方，需要的可以自取。
该系统的功能：1对所有品牌的增删改查；2可以批量删除品牌信息；3可以条件查询品牌，模糊查询品牌，根据状态查询品牌；
该系统的小彩蛋：1将鼠标放在登录后的用户头像上可以显示用户的信息；2鼠标点击页面会出现小心心
1.开发环境：jdk11+win11+mysql 8.0.25+IDEA+tomcat 8.5.77+maven 3.6.3+mybatis(直接maven添加依赖)
2.maven项目下（pom.xml）所导入的依赖和插件：
<dependencies>
<!--Servlet-->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
<!--MyBatis-->

<build>

<plugins>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
</plugin>
</plugins>
</build>3.数据库设计
（1）tb_brand_user表
（2）tb_brand表
4.登录页面
当输入账号密码并且点击登录后，会通过vue技术向web服务器的servlet发送请求，然后servlet容器在访问数据库，如果有这个用户的信息，然后把这个用户的信息写入session，以便后面的注销，最后把数据在响应给vue ，然后进行页面跳转到品牌页面。

对品牌的所有操作也是通过vue来请求servlet再访问数据库来进行操作的
