技术栈

1. 后端：Servlet 2. 前端：JSP+JavaScript+JQuery+CSS+Ajax

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. 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dbconnection.properties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/jsp_qzzp_sys/ 登录 注：Tomcat中配置的路径必须为/jsp_qzzp_sys 管理员账号/密码：admin/admin 求职者账号/密码：qiuzhi/123456 企业账号/密码：qiye/123456
