javaWeb用maven管理的ajax前后端分离的物业维修管理
说明：
1、效果展示使用maven项目
前后端分离
使用注解版Servlet（>3版本）
已维修
待维修
说明：
2、新建maven下的javaweb项目 1、新建项目 2、maven骨架选择 3、项目名 4、maven管理（重要） 5、项目结构 6、main下新建java，resource使用了ajax异步
使用了jQuery动态创建div
未实现翻页
右键main新建文件夹，一般会自动提示这两个文件夹
新建好后分别右击这两个文件夹
3、部分源码java包设置被javaroot，resources设置为resource root（一般idea自动会设置好的）
说明：
各层都做了简化处理

4、html
核心在js中，想要源码的私信笔者吧
由于篇幅的原因,这里只展示js
说明：
在页面加载的时候发送ajax请求
根据结果动态渲染
