JWT(鉴权)_学生管理系统

文章目录

• 需要实现的功能：
• • 整个项目架构
  • 创建数据库表
  • 创建整个工程父项目
  • 创建pojo项目
  • 创建工具项目
  • 创建Eureka项目
  • 创建zuul(网关)项目
  • 创建JWT鉴权项目
  • • 老师账号登录，采用JWT进行认证+授权
  • 创建老师项目
  • 创建班级项目
  • • 班级新增
    • 班级修改
    • 单个班级删除（假删）
    • 查询所有班级
  • 创建学生项目
  • • 学生新增
    • 学生批量删除
    • 多条件组合查询

需要实现的功能：

老师登录之后，可以对老师类型、老师信息、班级、学生信息进行管理。

1、老师账号登录，采用JWT进行认证+授权
2、班级管理

• 班级新增（默认不删除状态，也就是is_delete的默认值是0）
• 班级修改
• 单个班级删除（假删除，修改is_delete字段）
• 查询所有班级（基本功能+老师信息+5分创建的老师信息共）

3、学生管理

• 学生新增
• 学生批量删除(在地址栏传递多个id过去)
• 学生分页多条件组合查询（名字模糊查询+年龄范围查询+性别+班级）

整个项目架构

创建整个工程父项目

• 把src目录删除掉
• 导入pom文件 (父工程就创建完毕)
