Master the Excel Templateer framework in the Java Class Library to write efficient export work

Excel Templateer framework is a powerful and efficient Java class library for exporting Excel files.It can help developers to easily generate Excel templates and fill in data in the template to quickly export complex Excel reports.In this article, we will introduce how to use the Excel Templateer framework to write efficient export functions and provide some Java code examples. First, we need to introduce the dependency item of the Excel Templateer framework.You can add the following dependencies to the Maven configuration file: <dependency> <groupId>com.templater</groupId> <artifactId>excel-templater</artifactId> <version>1.0.0</version> </dependency> Once we have imported the Excel Templator framework, we can write efficient export functions according to the following steps: 1. Create Excel template: First of all, we need to create an Excel template that can use Microsoft Excel or other electronic meter editors to create template files, and insert the label position in the template in the place where the data needs to be filled.The mark is usually surrounded by a pair of large brackets `}`, such as `{firstName}`.These marks will be replaced with data in the following code. 2. Load template files: Use the `ExcelWriter` class of the Excel Templateer framework to load the Excel template file we created. ExcelWriter writer = new ExcelWriter("template.xlsx"); 3. Create a data model: Before filling the data to the template, we need to create a data model. It can be a POJO class or a `Map` object. public class Employee { private String firstName; private String lastName; // Other attributes and Getter, Setter methods } or Map<String, Object> dataModel = new HashMap<>(); dataModel.put("firstName", "John"); dataModel.put("lastName", "Doe"); 4. Fill in data: Fill in the data with the `` write` method of the `Excelwriter` class.We need to specify the mark and corresponding data. writer.write("firstName", employee.getFirstName()); writer.write("lastName", employee.getLastName()); 5. Save exported Excel file: Use the `Save` method of the` Excelwriter` class to fill the data into the template and save it as the exported Excel file. writer.save("output.xlsx"); The complete example code is as follows: public class ExcelExport { public static void main(String[] args) { // Create an excelwriter object ExcelWriter writer = new ExcelWriter("template.xlsx"); // Create a data model Employee employee = new Employee(); employee.setFirstName("John"); employee.setLastName("Doe"); // Data input writer.write("firstName", employee.getFirstName()); writer.write("lastName", employee.getLastName()); // Save the exported excel file writer.save("output.xlsx"); } } By using the Excel Templateer framework, we can easily generate complex Excel reports and achieve efficient export functions.I hope this article will help you understand the efficient export function of the Excel Templateer framework in the Java class library.
