Java class library Excel Templaater framework use guide
Overview:
Excel Templateer is a Java class library that can easily generate Excel reports conveniently and quickly.It provides a simple and easy -to -use API that allows developers to fill the data into the Excel table through templates.This article will introduce the guidelines for the use of the Excel Templator framework and come with some Java code examples.
Install Excel Template:
To use the Excel Templateer framework, you need to download and install it first.You can obtain the jar file of Excel Templateer from the official website or Maven warehouse, and add it to the project's dependence.
Create Excel template:
Before using Excel Templateer, you first need to create an Excel template.You can use Microsoft Excel or other similar software to create a template containing data occupation symbols.These placeholders will be replaced with actual values when filling data.Different worksheets and cells can be used as a placeholder in the template.
Example code:
import com.github.liuhuagui.gridexcel.templater.Templater;
public class ExcelGenerator {
public static void main(String[] args) {
Templater templater = new Templater();
templater.readTemplate("template.xlsx");
// Data input
templater.addvalue ("name", "Zhang San");
templater.addValue("age", 25);
templater.addvalue ("address", "Beijing");
// Save the generated excel file
templater.writeToFile("output.xlsx");
System.out.println ("Excel generated success!");
}
}
Read the template:
In the above code example, we first created a Template instance and used the `ReadTemplate ()" method to read an Excel template called "Template.xlsx".This method can accept the path of the template file as the parameter.
Data input:
Next, we use the `addvalue ()` method to add data to the template.This method accepts two parameters. The first parameter is the positioning of the data in the template, and the second parameter is the actual value to be filled.In the example, we use the "name", "Age" and "Address" as a placeholder, and then fill the corresponding name, age, and address value.
Save the excel file:
Finally, we use the `` writetofile () `method to save the data that fills the data into a new Excel file.This method accepts a file path as a parameter to specify the path and name of the saving file.
Summarize:
Through the Excel Templateer framework, we can easily generate Excel reports.You only need to create a template containing the data occupying symbol, and then use the Java code to fill the data and save it as a new Excel file.Compared with manual operations, using Excel Templater can improve development efficiency and reduce errors.I hope this article can help you quickly get started with Excel Templateer framework and provide the corresponding Java code example.
