功能说明

基于javaweb的SSM+Maven学生学籍管理系统(java+ssm+layui+maven+mysql+jsp)

项目介绍

SSM项目-学生学籍管理系统。该项目分管理员、老师、学生三种用户角色。每种角色分别对应不同的菜单；

以下分别介绍各个角色对应的功能模块：

管理员角色：

  • 用户登录和退出 - 权限控制 - 系统管理 - 专业管理 - 班级管理 - 学生管理 - 老师管理 - 课程管理 - 开课管理 - 用户管理

老师角色：

  • 老师管理 - 成绩管理 - 学生查询

学生角色：

  • 学生管理 - 选课管理 - 成绩查询

技术路线

  • 开发工具：IDEA 2020.1 - 技术框架：Spring、SpringMVC、MyBatis - Web容器：Tomcat 8.5.7 - 数据库：MySQL 5.7 - 前端UI框架：LayUI - 项目管理：Maven 3.6.3

使用说明

  1. 使用IDEA/Eclipse/MyEclipse导入项目，Eclipse/MyEclipse导入时，若为maven项目请选择maven; 若为maven项目，导入成功后请执行maven clean;maven install命令，下载所需jar包； 2. 使用Navicat或者其它工具，在mysql中创建对应名称的数据库，并导入项目的sql文件； 3. 将项目中application.yml配置文件中的数据库配置改为自己的配置 4. 配置tomcat，然后运行项目，输入localhost:8080 登录

压缩完上下文后，Agent 怎么还记得你的开发习惯

本文介绍了Claude代码项目中Memory机制的实现，用于跨任务保存关键信息。Memory分为用户偏好、反馈意见、项目背景和参考线索四类，存储在.memory/目录下的独立Markdown文件中，并通过MEMORY.md目录索引。Agent通过轻量模型调用选择相关记忆加载，每次最多读取5条。记忆提取发生在消息压缩前，以保留原始完整信息。当记忆文件达到10条时会触发合并整理，但存在信息失真的风险。
