I have two csv sources to read data from. Both of the csv files provide the same data but with different name or column location. Is there a way to add @CsvBindByByName with "OR". For example, the headers of two files are as follows
CSV 1 - RollNo, StudentName, Class, Age, PrimaryLanguage, ProjectName
CSV 2 - Name, Class, PrimLang, EnrollmentNumber, Age, Project, AttendancePercentage
And I have to read both of the csv file information in same POJO.
public class StudentInfo{
@CsvBindByName(column = "RollNo")
private String rollNo;
@CsvBindByName(column = "StudentName")
private String studentName;
@CsvBindByName(column = "PrimaryLanguage")
private String primaryLanguage;
@CsvBindByName(column = "Class")
private String class;
@CsvBindByName(column = "ProjectName")
private String projectName;
@CsvBindByName(column = "Age")
private String age;
//getters and setters
}
Or is there an alternate way to achieve this. My code is working fine if I take only one csv header format. Thanks
Profiles
in opencsv solves this problem, but it is only available from 5.4.
See documentation on Profiles
Below is a code snippet from the official documentation.
public class Person {
@CsvBindByNames({
@CsvBindByName(column = "last name"),
@CsvBindByName(profiles = {"customer 2", "customer 5"})
})
private String surname;
@CsvBindByNames({
@CsvBindByName,
@CsvBindByName(column = "first name", profiles = "customer 1"),
@CsvBindByName(column = "given name", profiles = "customer 2")
})
private String name;
@CsvIgnore(profiles = "customer 2")
@CsvBindByName(column = "middle initial")
private char initial;
@CsvBindByName(column = "salary", profiles = "customer 1")
@CsvBindByName(column = "annual salary", profiles = "customer 2")
@CsvNumber(value = "#0.00", profiles = "customer 1")
@CsvNumber(value = "0.0#E0", profiles = "customer 2")
private float salaryInUSD;
@CsvBindByName(column = "height")
@CsvNumbers({
@CsvNumber("000"),
@CsvNumber(value = "000cm", profiles = "customer 2")
})
private int heightInCentimeters
// Accessor methods go here.
}
// Now, the profile can be used in the builder parse, see below.
List<Person> beans = new CsvToBeanBuilder<Person>(inputfile)
.withProfile("customer 1")
.withType(Person.class)
.build()
.parse();
