Xcelite framework: Excelly imported and exported tutorial in the Java class library
Introduction:
Xcelite is a convenient and easy -to -use Java class library for importing and exporting the Excel data in Java applications.The framework provides a simple API, making the processing Excel file simple and efficient.This tutorial will introduce you how to use the Xcelite framework to import and export the Excel data in the Java class library.
Step 1: Installation and settings
First, you need to add the Xcelite framework to your Java project.You can add it to your project through Maven, just add the following dependencies to your pom.xml file:
<dependency>
<groupId>com.googlecode.xcelite</groupId>
<artifactId>xcelite</artifactId>
<version>1.2.3</version>
</dependency>
Step 2: Import Excel data
To import Excel data, you first need to create a Java class to represent your data model.Make sure your class defines the attribute corresponding to the columns in the Excel table.
import com.googlecode.xcelite.annotate.Column;
public class Person {
@Column (name = "name")
private String name;
@Column (name = "age")
private int age;
// Getter and Setter methods
}
Next, you need to write a method to read the excel file and convert it to the Java object.Using Xcelite's `SheetReaderBuilder` and` SheetReader "can easily complete this operation.
import java.io.File;
import java.util.List;
import com.googlecode.xcelite.reader.SheetReader;
import com.googlecode.xcelite.reader.SheetReaderBuilder;
import com.googlecode.xcelite.sheet.XceliteSheet;
public class ExcelImporter {
public List<Person> importExcelData(File file) {
SheetReaderBuilder<Person> builder = new SheetReaderBuilder<>(Person.class);
XceliteSheet sheet = builder.setUseHeaderRow(true).setSkipRows(1).addSheet(file).getSheet();
SheetReader<Person> reader = builder.build(sheet);
return reader.read();
}
}
Step 3: Export Excel data
To export Excel data, you need to prepare the data set to be exported and create an `sheetwriter` object.Then write the Java object list into the `SheetWriter` and save it as an excel file.
import java.io.File;
import java.util.List;
import java.util.Arrays;
import com.googlecode.xcelite.writer.SheetWriter;
import com.googlecode.xcelite.writer.SheetWriterImpl;
import com.googlecode.xcelite.sheet.XceliteSheet;
import com.googlecode.xcelite.writer.RowWriter;
public class ExcelExporter {
public void exportExcelData(File file, List<Person> persons) {
XceliteSheet sheet = new Xcelite().createSheet("Sheet1");
SheetWriter<Person> writer = new SheetWriterImpl<>(sheet, Person.class);
persons.forEach(writer::addRow);
writer.finish();
sheet.getSheetData().write(file);
}
}
Code explanation:
-` SHEETREADERBUILEDER `is used to configure the structure of SheetReader.
-`addsheet (file)` adds the excel file to the `sheetReaderbuilder`.
-` builder.build (sheet) `Returns a sheetReader object.
-` Read () `method will read the excel file and return a list containing the Person object.
-` SHEETWRITERIMPL` is used to create SheetWriter objects.
-`addRow ()` method adds Java objects to SheetWriter.
-`Finish ()` Method completes the writing operation.
-` SHEET.GetSheetdata (). Write (file) `writes sheetdata into Excel files.
in conclusion:
Using the Xcelite framework, you can easily import and export the Excel data in the Java class library.This tutorial introduces how to use Xcelite for the import and export of excel data. You can modify the code according to your needs.I hope this tutorial will help you, I wish you a happy framework for you!
