# 详细参数介绍
## 关于常见类解析
* EasyExcel 入口类,用于构建开始各种操作
* ExcelReaderBuilder ExcelWriterBuilder 构建出一个 ReadWorkbook WriteWorkbook,可以理解成一个excel对象,一个excel只要构建一个
* ExcelReaderSheetBuilder ExcelWriterSheetBuilder 构建出一个 ReadSheet WriteSheet对象,可以理解成excel里面的一页,每一页都要构建一个
* ReadListener 在每一行读取完毕后都会调用ReadListener来处理数据
* WriteHandler 在每一个操作包括创建单元格、创建表格等都会调用WriteHandler来处理数据
* 所有配置都是继承的,Workbook的配置会被Sheet继承,所以在用EasyExcel设置参数的时候,在EasyExcel...sheet()方法之前作用域是整个sheet,之后针对单个sheet
## 读
### 注解
* `ExcelProperty` 指定当前字段对应excel中的那一列。可以根据名字或者Index去匹配。当然也可以不写,默认第一个字段就是index=0,以此类推。千万注意,要么全部不写,要么全部用index,要么全部用名字去匹配。千万别三个混着用,除非你非常了解源代码中三个混着用怎么去排序的。
* `ExcelIgnore` 默认所有字段都会和excel去匹配,加了这个注解会忽略该字段
* `DateTimeFormat` 日期转换,用`String`去接收excel日期格式的数据会调用这个注解。里面的`value`参照`java.text.SimpleDateFormat`
* `NumberFormat` 数字转换,用`String`去接收excel数字格式的数据会调用这个注解。里面的`value`参照`java.text.DecimalFormat`
### 参数
#### 通用参数
`ReadWorkbook`,`ReadSheet` 都会有的参数,如果为空,默认使用上级。
* `converter` 转换器,默认加载了很多转换器。也可以自定义。
* `readListener` 监听器,在读取数据的过程中会不断的调用监听器。
* `headRowNumber` 需要读的表格有几行头数据。默认有一行头,也就是认为第二行开始起为数据。
* `head` 与`clazz`二选一。读取文件头对应的列表,会根据列表匹配数据,建议使用class。
* `clazz` 与`head`二选一。读取文件的头对应的class,也可以使用注解。如果两个都不指定,则会读取全部数据。
* `autoTrim` 字符串、表头等数据自动trim
#### ReadWorkbook(理解成excel对象)参数
* `excelType` 当前excel的类型 默认会自动判断
* `inputStream` 与`file`二选一。读取文件的流,如果接收到的是流就只用,不用流建议使用`file`参数。因为使用了`inputStream` easyexcel会帮忙创建临时文件,最终还是`file`
* `file` 与`inputStream`二选一。读取文件的文件。
* `autoCloseStream` 自动关闭流。
* `readCache` 默认小于5M用 内存,超过5M会使用 `EhCache`,这里不建议使用这个参数。
#### ReadSheet(就是excel的一个Sheet)参数
* `sheetNo` 需要读取Sheet的编码,建议使用这个来指定读取哪个Sheet
* `sheetName` 根据名字去匹配Sheet,excel 2003不支持根据名字去匹配
## 写
### 注解
* `ExcelProperty` index 指定写到第几列,默认根据成员变量排序。`value`指定写入的名称,默认成员变量的名字,多个`value`可以参照快速开始中的复杂头
* `ExcelIgnore` 默认所有字段都会写入excel,这个注解会忽略这个字段
* `DateTimeFormat` 日期转换,将`Date`写到excel会调用这个注解。里面的`value`参照`java.text.SimpleDateFormat`
* `NumberFormat` 数字转换,用`Number`写excel会调用这个注解。里面的`value`参照`java.text.DecimalFormat`
### 参数
#### 通用参数
`WriteWorkbook`,`WriteSheet` ,`WriteTable`都会有的参数,如果为空,默认使用上级。
* `converter` 转换器,默认加载了很多转换器。也可以自定义。
* `writeHandler` 写的处理器。可以实现`WorkbookWriteHandler`,`SheetWriteHandler`,`RowWriteHandler`,`CellWriteHandler`,在写入excel的不同阶段会调用
* `relativeHeadRowIndex` 距离多少行后开始。也就是开头空几行
* `needHead` 是否导出头
* `head` 与`clazz`二选一。写入文件的头列表,建议使用class。
* `clazz` 与`head`二选一。写入文件的头对应的class,也可以使用注解。
* `autoTrim` 字符串、表头等数据自动trim
#### WriteWorkbook(理解成excel对象)参数
* `excelType` 当前excel的类型 默认`xlsx`
* `outputStream` 与`file`二选一。写入文件的流
* `file` 与`outputStream`二选一。写入的文件
* `templateInputStream` 模板的文件流
* `templateFile` 模板文件
* `autoCloseStream` 自动关闭流。
#### WriteSheet(就是excel的一个Sheet)参数
* `sheetNo` 需要写入的编码。默认0
* `sheetName` 需要些的Sheet名称,默认同`sheetNo`
#### WriteTable(就把excel的一个Sheet,一块区域看一个table)参数
* `tableNo` 需要写入的编码。默认0
