私信源码获取及调试交流

运行环境

Java≥8、MySQL≥5.7、Tomcat≥8

开发工具

eclipse/idea/myeclipse/sts等均可配置运行

适用

课程设计，大作业，毕业设计，项目练习，学习演示等

功能说明

基于javaweb的SSM学生成绩信息管理系统(java+ssm+html+layui+mysql)

项目介绍

本项目分为管理员、教师、学生三种角色，管理员角色包含以下功能：公告管理,写公告,学生增删改查,教师增删改查,查看成绩报表,管理员首页,课程表增删改查等功能。教师角色包含以下功能：修改密码,按照条件查询,查看学生信息,管理课程,登陆页面等功能。学生角色包含以下功能：查看成绩信息,查看课程信息,选课操作等功能。

环境需要

1.运行环境：最好是java jdk 1.8，我们在这个平台上运行的。其他版本理论上也可以。 2.IDE环境：IDEA，Eclipse,Myeclipse都可以。推荐IDEA; 3.tomcat环境：Tomcat 7.x,8.x,9.x版本均可 4.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS； 5.数据库：MySql 5.7版本； 6.是否Maven项目：否；

技术栈

后端：Spring+SpringMVC+Mybatis 2. 前端：HTML+LayUI

使用说明

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； 2. 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，然后运行； 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. 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。
