Java Read CSV File In Java With OpenCSV library, int filed 属性为 int类型
sample2.csv
COUNTRY,CAPITAL,POPULATIONIndia,New Delhi, 100People's republic of China,Beijing, 200United States,Washington D.C., 300
Country2.java 中population 为int类型:
package com.jiangge.csv.opencsvtest;public class Country2 {private String countryName;private String capital;private int population;public String getCountryName() {return countryName;}public void setCountryName(String countryName) {this.countryName = countryName;}public String getCapital() {return capital;}public void setCapital(String capital) {this.capital = capital;}public int getPopulation() {return population;}public void setPopulation(int population) {this.population = population;}}
JavaBeanMapWithCSV2.java
package com.jiangge.csv.opencsvtest;import java.io.FileNotFoundException;import java.io.FileReader;import java.util.HashMap;import java.util.List;import java.util.Map;import au.com.bytecode.opencsv.CSVReader;import au.com.bytecode.opencsv.bean.CsvToBean;import au.com.bytecode.opencsv.bean.HeaderColumnNameTranslateMappingStrategy;//sample2.csv//COUNTRY,CAPITAL,POPULATION//India,New Delhi, 100//People's republic of China,Beijing, 200//United States,Washington D.C., 300public class JavaBeanMapWithCSV2 {public static void main(String[] args) {HeaderColumnNameTranslateMappingStrategy<Country2> strategy = new HeaderColumnNameTranslateMappingStrategy<Country2>();strategy.setType(Country2.class);Map<String, String> columnMapping = new HashMap<String, String>();columnMapping.put("COUNTRY", "countryName"); //关联columnMapping.put("CAPITAL", "capital"); //关联columnMapping.put("POPULATION", "population"); //关联strategy.setColumnMapping(columnMapping);List<Country2> list = null;String csvFilename = "C:\\sample2.csv";CSVReader reader = null;try {reader = new CSVReader(new FileReader(csvFilename));//CSVReader reader = new CSVReader(new InputStreamReader(ClassLoader.getSystemResourceAsStream("C:\\sample.csv")));} catch (FileNotFoundException e) {e.printStackTrace();}CsvToBean<Country2> csvToBean = new CsvToBean<Country2>();list = csvToBean.parse(strategy, reader);for (Object object : list) {Country2 country = (Country2) object;System.out.println(country.getCountryName() + " " + country.getPopulation());}}}
输出结果:
India 100People's republic of China 200United States 300
