枚举中文转数字并easyexcel导入（读取Read）数据至数据库，用监听器解决导入关联多表的问题

以下内容皆为本人学习过程中的所学的知识，全根据自己所学思路来写的。

大致流程如下：

一、创建实体类，注意有一个是导入的模板实体模型类（CustomManageAndCustomerInformationReadVO），有一个是这个模块的主表实体（CustomManage），模块主表实体才会连接到数据库的数据，而模板实体模型类是导入所要求有的字段，并且哪个字段在哪一列从0开始。

二、在controller层调用ExcelUtils工具类下的customerInformationReadExcel()方法。
三、进入ExcelUtils工具类编写customerInformationReadExcel()方法，其中需要调用到CustomManageListener()监听器也可称之为解析器。

四、导入的难点就在于监听器的编写，如若导入的数据属于一张表还不难，重点是我这次做的是多表的，需要进行连表操作，调用其他表的mapper和service。不会做就觉得难。做了觉得也还行不是特别难，就像地上本没有路走的人多了也就成了路。监听器中调用了公共枚举中文转数字的方法。

五、进入公共枚举类，编写中文转数字的getEnumNum()方法,实现中文获取数字,导入，(从excel中导入数据至数据库)。

2.在controller层调用ExcelUtils工具类下的customerInformationReadExcel()方法。

 /*** 根据客户信息导入模板批量导入** @param* @return* @throws Exception*/@PreAuthorize("hasPermit('sale:client')")@RequestMapping(value = "/customerInformationReadExcel", method = RequestMethod.POST, produces = "application/octet-stream")@ApiOperation(value = "客户信息导入(按照模板导入)", tags = {"销售模块", "客户信息导入(按照模板导入)"})public Result customerInformationReadExcel(@RequestPart @RequestParam(value = "file", required = false) MultipartFile file)throws Exception {try {ExcelUtils.customerInformationReadExcel(file.getInputStream());return Result.success(ResultCode.成功, ResultCode.成功.getCode());} catch (Exception e) {return Result.error(ResultCode.失败.getMsg(), ResultCode.失败.getCode(), null);}}

3.进入ExcelUtils工具类编写customerInformationReadExcel()方法，其中需要调用到CustomManageListener()监听器也可称之为解析器。

/*** 根据客户信息导入模板批量导入* @param inputStream*/public static void customerInformationReadExcel(InputStream inputStream) {EasyExcel.read(inputStream, CustomManageAndCustomerInformationReadVO.class,new CustomManageListener()).registerConverter(new LocalDateTimeConverter()).sheet().doRead();}

4.导入的难点就在于监听器的编写，如若导入的数据属于一张表还不难，重点是我这次做的是多表的，需要进行连表操作，调用其他表的mapper和service。不会做就觉得难。做了觉得也还行不是特别难，就像地上本没有路走的人多了也就成了路。监听器中调用了公共枚举中文转数字的方法。

6.进入主表的mappe进行连表操作，需要用到的字段都要在前面标明是哪个表里的什么字段as别名是什么,进行连表的字段还需在主表也就是本模块的实体类中标注注解此字段不在本表中，不然导出的数据会出现有些字段无数据。
