csv文件轉換爲javaBean

1.首先導入相關的csv包
compile group: ‘com.opencsv’, name: ‘opencsv’, version: ‘4.0’
2.首先定義javaBean
public class AssetType {
//這個註解的意思是讓你綁綁定列名
@CsvBindByName(column = “收入id”)
private String id;
@CsvBindByName(column = “資產ID”)
private String typeId;
@CsvBindByName(column = “用戶”)
private String name;
｝
3.創建解析對象，這裏把它抽出來作爲一個通用的方法
public static List parseCsvToBean(File file, Class clazz) throws Exception {
FileInputStream is = new FileInputStream(file);
InputStreamReader isr = new InputStreamReader(is, “utf-8”);
HeaderColumnNameMappingStrategy strategy = new HeaderColumnNameMappingStrategy<>();
strategy.setType(clazz);
CsvToBean csvToBean = new CsvToBeanBuilder(isr)
.withMappingStrategy(strategy).build();
isr.close();
is.close();
return csvToBean.parse();
}
