以下內(nèi)容皆為本人學(xué)習(xí)過(guò)程中的所學(xué)的知識(shí)，全根據(jù)自己所學(xué)思路來(lái)寫(xiě)的。

大致流程如下：

一、創(chuàng)建實(shí)體類，注意有一個(gè)是導(dǎo)入的模板實(shí)體模型類（CustomManageAndCustomerInformationReadVO），有一個(gè)是這個(gè)模塊的主表實(shí)體（CustomManage），模塊主表實(shí)體才會(huì)連接到數(shù)據(jù)庫(kù)的數(shù)據(jù)，而模板實(shí)體模型類是導(dǎo)入所要求有的字段，并且哪個(gè)字段在哪一列從0開(kāi)始。

二、在controller層調(diào)用ExcelUtils工具類下的customerInformationReadExcel()方法。
三、進(jìn)入ExcelUtils工具類編寫(xiě)customerInformationReadExcel()方法，其中需要調(diào)用到CustomManageListener()監(jiān)聽(tīng)器也可稱之為解析器。

四、導(dǎo)入的難點(diǎn)就在于監(jiān)聽(tīng)器的編寫(xiě)，如若導(dǎo)入的數(shù)據(jù)屬于一張表還不難，重點(diǎn)是我這次做的是多表的，需要進(jìn)行連表操作，調(diào)用其他表的mapper和service。不會(huì)做就覺(jué)得難。做了覺(jué)得也還行不是特別難，就像地上本沒(méi)有路走的人多了也就成了路。監(jiān)聽(tīng)器中調(diào)用了公共枚舉中文轉(zhuǎn)數(shù)字的方法。

五、進(jìn)入公共枚舉類，編寫(xiě)中文轉(zhuǎn)數(shù)字的getEnumNum()方法,實(shí)現(xiàn)中文獲取數(shù)字,導(dǎo)入，(從excel中導(dǎo)入數(shù)據(jù)至數(shù)據(jù)庫(kù))。

1.創(chuàng)建實(shí)體類，注意有一個(gè)是導(dǎo)入的模板實(shí)體模型類（CustomManageAndCustomerInformationReadVO），有一個(gè)是這個(gè)模塊的主表實(shí)體（CustomManage），模塊主表實(shí)體才會(huì)連接到數(shù)據(jù)庫(kù)的數(shù)據(jù)，而模板實(shí)體模型類是導(dǎo)入所要求有的字段，并且哪個(gè)字段在哪一列從0開(kāi)始。

2.在controller層調(diào)用ExcelUtils工具類下的customerInformationReadExcel()方法。

/*** 根據(jù)客戶信息導(dǎo)入模板批量導(dǎo)入** @param* @return* @throws Exception*/@PreAuthorize("hasPermit('sale:client')")@RequestMapping(value = "/customerInformationReadExcel", method = RequestMethod.POST, produces = "application/octet-stream")@ApiOperation(value = "客戶信息導(dǎo)入(按照模板導(dǎo)入)", tags = {"銷售模塊", "客戶信息導(dǎo)入(按照模板導(dǎo)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.失敗.getMsg(), ResultCode.失敗.getCode(), null);}}

3.進(jìn)入ExcelUtils工具類編寫(xiě)customerInformationReadExcel()方法，其中需要調(diào)用到CustomManageListener()監(jiān)聽(tīng)器也可稱之為解析器。

/*** 根據(jù)客戶信息導(dǎo)入模板批量導(dǎo)入* @param inputStream*/public static void customerInformationReadExcel(InputStream inputStream) {EasyExcel.read(inputStream, CustomManageAndCustomerInformationReadVO.class,new CustomManageListener()).registerConverter(new LocalDateTimeConverter()).sheet().doRead();}

4.導(dǎo)入的難點(diǎn)就在于監(jiān)聽(tīng)器的編寫(xiě)，如若導(dǎo)入的數(shù)據(jù)屬于一張表還不難，重點(diǎn)是我這次做的是多表的，需要進(jìn)行連表操作，調(diào)用其他表的mapper和service。不會(huì)做就覺(jué)得難。做了覺(jué)得也還行不是特別難，就像地上本沒(méi)有路走的人多了也就成了路。監(jiān)聽(tīng)器中調(diào)用了公共枚舉中文轉(zhuǎn)數(shù)字的方法。
