示例直接看代码吧：
我们首先定义一个Student的Bean：
class Student {public Student() {}public Student(String id, String name, String gender, String major) {super();this.id = id;this.name = name;this.gender = gender;this.major = major;}private String id;private String name;private String gender;private String major;public String getID() {return id;}public void setID(String id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getGender() {return gender;}public void setGender(String gender) {this.gender = gender;}public String getMajor() {return major;}public void setMajor(String major) {this.major = major;}@Overridepublic String toString() {return id + ',' + name + ',' + gender + ',' + major;}}
如下是读写CSV的代码：
import java.io.FileReader;import java.io.FileWriter;import java.io.Reader;import java.io.Writer;import java.util.ArrayList;import java.util.List;import mons.csv.CSVFormat;import mons.csv.CSVPrinter;import mons.csv.CSVRecord;public class CSVDemo {public static void main(String[] arg) {final String[] FILE_HEADER = {"ID","Name","Gender","Major"};final String FILE_NAME = "student.csv";Student stuTZY = new Student("001", "谭振宇", "男", "GIS");Student stuZJL = new Student("002", "周杰伦", "男", "音乐");List<Student> students = new ArrayList<>();students.add(stuTZY);students.add(stuZJL);// 这里显式地配置一下CSV文件的Header，然后设置跳过Header（要不然读的时候会把头也当成一条记录）CSVFormat format = CSVFormat.DEFAULT.withHeader(FILE_HEADER).withSkipHeaderRecord();// 这是写入CSV的代码try(Writer out = new FileWriter(FILE_NAME);CSVPrinter printer = new CSVPrinter(out, format)) {for (Student student : students) {List<String> records = new ArrayList<>();records.add(student.getID());records.add(student.getName());records.add(student.getGender());records.add(student.getMajor());printer.printRecord(records);}} catch (Exception e) {e.printStackTrace();}// 这是从上面写入的文件中读出数据的代码try(Reader in = new FileReader(FILE_NAME)) {Iterable<CSVRecord> records = format.parse(in);String strID;String strName;for (CSVRecord record : records) {strID = record.get("ID");strName = record.get("Name");System.out.println(strID + " " + strName);}} catch (Exception e) {e.printStackTrace();}}}
输入结果：
001 谭振宇002 周杰伦
