QueryRunner Insert method Return Type

I am using Apache Commons DBUtils according to QueryRunner#insert method in its documentation, insert return the generic type of ResultSetHandler. I have a BR_Author object for my project.

BR_Author.java

import org.springframework.stereotype.Repository;

@Repository
public class BR_Author {
    private int id;
    private String authorName;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getAuthorName() {
        return authorName;
    }

    public void setAuthorName(String authorName) {
        this.authorName = authorName;
    }
}

I write a simple insert statement at my service class like

AuthorService#createAuthor

public BR_Author createAuthor(String authorName) throws ApiException {
        String sql = "Insert into BR_AUTHOR(authorName) VALUES(?)";
        ResultSetHandler<BR_Author> rs = new BeanHandler<BR_Author>(
                BR_Author.class);
        QueryRunner qr = new QueryRunner(dataSource);
        Object[] params = { authorName };
        try {
            BR_Author author = qr.insert(sql, rs, params);
            System.out.println("Br_Author:" + author);
            return author;

        } catch (SQLException e) {
            throw new ApiException(ErrorCode.ERR20001, e.getMessage());
        }
    }

I am trying to return the added value at the createAuthor method, but if i configure the id field as auto-increment object return as

Br_Author:Br_Author [id=0, authorName=null]

when I check the db I see that it adds the values successfully.

If I disable auto-increment and set the id from the code, the author object is null. So I want to learn that am I misunderstood the QueryRunner#insert method or if it has a bug. I already checked the below links.

• QueryRunner_insert_add_javadoc.patch
• Generated key handling for updates

BTW: Select queries working fine for the BR_Author class so it means there shouldn't be any mapping issue.

I didn't find any official solution from DBUtils API so i just return generated ID and then query it after insert the record with this id at Service layer. This way method return Object at service layer, but i do one extra query.
