基于javaweb和mysql的ssm大学生兼职论坛(java+ssm+jsp+jquery+layui+mysql)

私信源码获取及调试交流

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大学生兼职论坛(java+ssm+jsp+jquery+layui+mysql)

项目介绍

该项目是一个大学生校园兼职讨论平台，分为前台和后台功能，主要用户有三种角色：分别是商家、学生、管理员。商家可以发布兼职信息，发布后，管理员进入后台确认信息是否有效，并且审核该兼职信息。学生登录平台后，可以查看兼职信息，并且，可以在线和商家聊天，聊天的内容持久化到mysql数据库中。 该网站还有论坛交流的功能，用户可以在论坛发表贴子，并且，可以在帖子下面回复。论坛版块设置有3块广告区，管理员可以在后台对广告进行增删改查。 整体功能包括：论坛交流，帖子发布，个人中心，用户管理，聊天管理，帖子管理。

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；

技术栈

1. 后端：Spring SpringMVC MyBatis 2. 前端：JSP+jQuery+Layui

使用说明

1. 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. 将项目中yml配置文件中的数据库配置改为自己的配置 3. 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，配置tomcat，然后运行；

前台系统：http://localhost:8080/moonlighting/

后台系统：http://localhost:8080/moonlighting/manager/login/goServerLogin.action
