Introduction to Light Excel Reader framework in the Java class library
Light Excel Reader is a lightweight Java class library for reading and analyzing Excel files.It provides a simple and easy -to -use API that enables developers to quickly read and process data in Excel files.Regardless of the introduction of data or data analysis and processing, Light Excel Reader can help developers improve productivity.
Light Excel Read supports different versions of reading Excel files, including early Excel 97-2003 (.xls files) and the latest Excel 2007 and above versions (.xlsx files).It can analyze the worksheets, cells and formulas in Excel files, as well as reading the reading of multiple data types, such as string, numbers, date, and Boolean values.
Here are a simple example of reading the excel file and output data using Light Excel Reader:
import com.github.liaochong.myexcel.core.DefaultStreamExcelReader;
import com.github.liaochong.myexcel.utils.AttachmentExportUtil;
import java.io.InputStream;
public class ExcelReaderExample {
public static void main(String[] args) {
try (InputStream inputStream = ExcelReaderExample.class.getResourceAsStream("/path/to/excel.xlsx")) {
DefaultStreamExcelReader excelReader = new DefaultStreamExcelReader(inputStream, true);
excelReader.read()
.sheet()
.doRead((event) -> {
// Process each line of data
System.out.println(event.getCurrentRow());
});
} catch (Exception e) {
e.printStackTrace();
}
}
}
In the above example, we first created an object of `defaultStreamExcelReader, which is used to read the Excel file under the specified path.By calling `. READ (). Sheet ()` method, we can further configure the read settings, such as specified sheets to read.In the method of `.doread ((event) -> {...}), we could process each line of data. Here we simply output each line of data to the console.
In addition to reading Excel files, Light Excel Reader also provides many other functions and extensions, including reading specific columns, screening data, processing large data imports, verification data, etc.It also supports seamless integration with the Spring framework, enabling developers to use the characteristics of Spring to develop more easily.
In short, Light Excel Reader is a powerful and easy -to -use Java class library that helps developers to read and process data in Excel files efficiently.Whether it is a personal user or a business developer, it can improve the work efficiency through Light Excel Reader and simplify the process of importing and data processing of Excel files.
