Analysis of the comparison and advantages and disadvantages of JXLS Reader and other Excel reading frameworks

JXLS Reader is a Java framework for reading Excel files. It has some unique advantages compared to other popular Excel reading frameworks. 1. Performance advantage: JXLS Reader performed well when processing large -scale excel files.It uses the memory optimization function provided by the Apache Poi library to effectively manage memory use, and can handle a large number of lines and columns.This makes it an ideal choice for processing complex and huge data sets. 2. Simplified API: JXLS Reader provides a simple and easy -to -use API, making it very simple to read and operate the Excel file.Through several lines of code, you can open your workbook, choose a worksheet, and read and update the cell data.This simplified API allows developers to quickly build a powerful Excel reading program. The following is an example code that reads the excel file using JXLS Reader: // Import the required JXLS Reader package import org.jxls.reader.ReaderBuilder; import org.jxls.reader.XLSReader; // The method of reading the excel file public void readExcelFile(String filePath) { try { // Create JXLS Reader XLSReader xlsReader = ReaderBuilder.buildFromXML(new File("mapping.xml")); // Open the excel file FileInputStream fileInputStream = new FileInputStream(new File(filePath)); // Create a data model in order to fill the read data Map<String, Object> beans = new HashMap<>(); // Read the excel file xlsReader.read(fileInputStream, beans); // Process read data // ... // Close the excel file fileInputStream.close(); } catch (Exception e) { e.printStackTrace(); } } In the above code, we first created a Xlsreader object and loaded a mapping file called "MAPPING.XML" by calling the `Buildfromxml` method.The mapping file is used to specify how the data in Excel is mapped to the Java object. Then, we use the `FileInputStream` to open the excel file and create a data model (MAP type) called" Beans "to store read data. Finally, we call the `Read` method to read the excel file, put the read data into the data model, and then use further processing data to use it. In summary, JXLS Reader is a powerful and easy -to -use Excel reading framework with excellent performance and simple API.Whether you need to read large Excel files or processing complex data sets, this framework is an ideal choice.
