read

public <T> void read(java.lang.Class<T> beanClz,
                     java.io.InputStream is,
                     RowListener<T> listener)
              throws SpreadsheetReadException

从接口复制的说明: SpreadsheetReader

Reads the spreadsheet file to beans of the given type. This method will attempt to read all the available sheets of the file and creates the objects of the passed type.

The RowListener implementation callback gets triggered after reading each Row. Best Suited for reading Large files in restricted memory environments.

类型参数:

T - The Parameterized bean Class.

参数:

beanClz - The Class type to deserialize the rows data

is - InputStream of the spreadsheet file

listener - Custom RowListener implementation for row data callbacks.

抛出:

SpreadsheetReadException - an exception is thrown in cases where the file data is not readable or row data to bean mapping failed.
