How to map csv file to pojo class in java


How to map csv file to pojo class in java

To fix this issue uniVocity-parsers allows you to map your pojo easily.
code :
class Employee {

    @Trim
    @LowerCase
    @Parsed
    private String firstName;

    @Parsed
    private String lastName;

    @NullString(nulls = { "?", "-" }) // if the value parsed in the quantity column is "?" or "-", it will be replaced by null.
    @Parsed(defaultNullRead = "0") // if a value resolves to null, it will be converted to the String "0".
    private Integer salary; // The attribute name will be matched against the column header in the file automatically.
    ...

}
BeanListProcessor<Employee> rowProcessor = new BeanListProcessor<Employee>(Employee.class);

CsvParserSettings parserSettings = new CsvParserSettings();
parserSettings.setRowProcessor(rowProcessor);
parserSettings.setHeaderExtractionEnabled(true);

CsvParser parser = new CsvParser(parserSettings);

//And parse!
//this submits all rows parsed from the input to the BeanListProcessor
parser.parse(new FileReader(new File("/path/to/your.csv"))); 

List<Employee> beans = rowProcessor.getBeans();

Any of those help I am using GSON to parse a JSON file and i want to map this JSON object to a POJO class. The problem is the property name in JSON doesn't have camel-case but my java POJO object having camel-case property name. , You can use @SerializedName annotation in this case.
code :
private class SomeObject {

  @SerializedName("OrderNumber") 
  private String salesNumber;

}

seems to work fine I am forced to use an interface method with the signature which I can not change: , Solved it, finally:
code :
@Override
List parse(String path, Class clazz) {
    List result = []
    JsonArray jsonArray = new JsonParser()
            .parse(new File(path).getText(CHARSET))
            .getAsJsonArray()

    Gson gson = new Gson()
    jsonArray.each {
        result.add(gson.fromJson(it, clazz))
    }
    return result
}

it should still fix some issue No, according quoting wikipedia a plain old java object should not: Ideally speaking, a POJO is a Java object not bound by any restriction other than those forced by the Java Language Specification; i.e. a POJO should not have extend prespecified classes, as in
code :
public class Foo extends javax.servlet.http.HttpServlet { ...
public class Bar implements javax.ejb.EntityBean { ...
@javax.persistence.Entity public class Baz { ...
