Controller控制层

一、 概述

1.作用

是Model与View之间沟通的桥梁，可以分派用户的请求并选择恰当的视图以用于显示，同时可以解释用户的输入并映射为模型层可执行的操作

请求顺序如下：

xxxx.html ——> controller ——> service ——>serviceImpl ——> mapper ——>mapper.xml

mapper.xml ——> mapper ——> serviceImpl ——> service ——> controller ——> xxxx.html

2.位置

包名：cn.ewsd.xxxx.Zzzz

3.命名方式

命名方式：XxxxController

4.继承

cn.ewsd.common.controller.BaseController

5.公用方法

序号	方法名	参数	方法描述
1	userInfo.getUserNameId()		获取当前用户ID
2	userInfo.getUserName()		获取当前用户名称
3	userInfo.getOrgId()		获取当前用户组织机构ID
4	userInfo.getUuid()		获取当前用户的UUID
5	userInfo.getRoleId()		获取当前用户角色ID
6	getSaveData(Object)	Object	此方法可直接赋值：UUID，创建时间，创建人ID，创建人名称。使用方法如：getSaveData(sysUserBase);使用情况：在需要给对象赋值UUID，创建时间，创建人ID，创建人名称的情况下使用
7	getUpdateData(Object)	Object	此方法可直接赋值：修改时间，修改人ID，修改人名称。使用方法如：getUpdateData(sysUserBase);使用情况：在需要给对象赋值修改时间，修改人ID，修改人名称的情况下使用
8	success(“保存成功！”)	message	返回成功状态码及提示信息statusCode默认是200message根据传递参数如： success(“保存成功！”)参数{statusCode：”300”, message:”保存成功！”}
9	failure(“保存失败！”)	message	返回失败状态码及提示信息statusCode默认是300message根据传递参数如： success(“保存失败！”)参数{statusCode：”200”,message:”保存失败！” }

二、示例代码

    }
                

    //编辑页面
    @RequestMapping("/edit")
