Inquire about Jackson DataFormats in the Java Library: Text framework technical principle

Jackson DataFormats: Text is a tool set in the Java class library that is used to process the text format data.It provides some specific functions and tools based on the Jackson framework, making processing text data easier and efficient. Jackson is a very popular Java library for processing JSON data.It provides a lightweight and high -performance way to serialize the Java object in JSON format, and the derivative JSON as the Java object.In addition to processing JSON data, Jackson also supports other data formats, such as XML, YAML, and Smile.Among them, Jackson DataFormats: Text is one of them. Jackson DataFormats: Text provides some additional modules, so that Jackson can process other text format data.These modules include: 1. CSV module: data used to read and write data in CSV (comma separation value) format.It supports customizable separators, quotes characters, and lines.Below is an example code that uses Jackson DataFormats: Text to read and write CSV data:: // Import the required class import com.fasterxml.jackson.dataformat.csv.CsvMapper; import com.fasterxml.jackson.dataformat.csv.CsvSchema; // Create CSVMAPPER instance CsvMapper csvMapper = new CsvMapper(); // Define the schema of CSV CsvSchema csvSchema = CsvSchema.builder() .addColumn("name") .addColumn("age") .build(); // Read csv data List<Object> data = csvMapper.readerFor(Object.class) .with(csvSchema) .readValues(csvFile) .readAll(); // Write into CSV data csvMapper.writerFor(Object.class) .with(csvSchema) .writeValues(csvFile) .writeAll(data); 2. Properties module: It is used to read and write the Java property file (Properties file).It provides the function of converting the Properties file into a Java object and converting the Java object into a Properties file.Below is an example code that uses Jackson DataFormats: Text to read and write to the Properties file: // Import the required class import com.fasterxml.jackson.dataformat.javaprop.JavaPropsMapper; import java.util.Properties; // Create javapropsmapper instance JavaPropsMapper propsMapper = new JavaPropsMapper(); // Read the Properties file Properties properties = propsMapper.reader() .readValue(propsFile); // Write into the Properties file propsMapper.writer() .writeValue(propsFile, properties); In short, the Jackson DataFormats: Text framework provides Jackson with the ability to process text format data through additional modules.It supports common text formats such as CSV and Properties, so that Java developers can easily process and convert these data formats.The code examples above demonstrate how to use Jackson DataFormats: Text to read and write to CSV and Properties files.
