项目介绍
车险理赔管理系统源码，分为两个角色，一个管理员，一个普通用户
主要功能说明：
管理员角色包含以下功能：管理员登录,个人资料修改,用户管理,公告管理,快递状态管理,快递品牌管理,快递管理等功能。
用户角色包含以下功能：
用户注册后登录,个人资料管理,公告查看,查看本人的快递等功能。
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.是否Maven项目: 否；查看源码目录中是否包含pom.xml；若包含，则为maven项目，否则为非maven项目
6.数据库：MySql 5.7等版本均可；
技术栈
1. 后端：Spring springmvc mybatis
2. 前端：JSP+css+javascript+jQuery
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，配置tomcat
