Excel Templateer framework Java class library tutorial

Excel Templateer framework is a Java class library for generating Excel documents. It provides simple and powerful functions that allow developers to easily use templates to generate complex Excel reports.This tutorial will introduce the basic usage of the Excel Templator framework and provide some Java code examples to help readers better understand. The core idea of the Excel Templateer framework is to divide the excel document into two parts: template and data.The template is a predetermined Excel file that contains a fixed format and style, and the data is dynamically generated according to specific needs.By filling the data in the position of the placement in the template, you can easily generate an Excel report that meets the requirements. The first step is to introduce the library file to the Excel Templator framework to the project.You can use Maven or manually download and add related jar files.The following is an example of the Maven project dependencies: <dependency> <groupId>com.github.guhaoxyz</groupId> <artifactId>excel-templater</artifactId> <version>1.0.0</version> </dependency> Next, we will write some Java code to demonstrate the basic usage of the Excel Templateer framework.First of all, we need to create a template file to replace the placeholders in it with actual data.For example, we can create an Excel file called "Template.xlsx", which contains a seat occupies that is called "{name}}". Then, we can use the following code to fill the template and generate the final Excel document: import com.github.guhaoxyz.excel.templater.ExcelSpringTemplate; import com.github.guhaoxyz.excel.templater.SheetData; import com.github.guhaoxyz.excel.templater.config.TemplaterConfig; public class ExcelTemplaterExample { public static void main(String[] args) { // Create template configuration TemplaterConfig config = new TemplaterConfig(); // Load the template file ExcelSpringTemplate template = new ExcelSpringTemplate(config); template.loadTemplate("template.xlsx"); // Create SheetData objects and fill in data SheetData sheetData = new SheetData(); sheetdata.put ("name", "Zhang San"); // Fill template.process(sheetData); // Save generated excel documentation template.save("output.xlsx"); } } In the above examples, we first created a TemplateerConfig object to configure the template.Then, we use the LoadTemplate method of the ExcelSpringTemplate class to load the template file.Next, create a sheetdata object to store the filling data, fill the data into the template, and finally save the generated Excel document saved by the save method of the ExcelSpringTemplate class. Through the above examples, we can see that the Excel Templateer framework provides a simple and easy -to -understand API, so that developers can easily use templates to generate complex Excel reports.I hope this tutorial can help readers get started and master the basic usage of the Excel Templateer framework.
