我已經(jīng)使用 mvnw install 命令從 git 存儲庫（[1]：https : //github.com/Devskiller/jfairy.git）構(gòu)建了 jFairy 項目。然后我已將編譯的 jar 文件導入到我的項目中。package userdao;import java.sql.Connection;import java.sql.DriverManager;import java.sql.PreparedStatement;import java.sql.SQLException;import java.sql.ResultSet;import com.devskiller.jfairy.Fairy;import com.devskiller.jfairy.producer.person.Person;import userdao.User;/** * * @author loveu */public class UserDao {    /**     * @param args the command line arguments     * @throws java.lang.ClassNotFoundException     * @throws java.sql.SQLException     */    public static void main(String[] args) throws ClassNotFoundException, SQLException {        UserDao dao = new UserDao();        User user = new User();        Fairy fairy = Fairy.create();        Person person = fairy.person();        user.setId(person.getFullName());        user.setName(person.getFirstName());        user.setPassword(person.getEmail());        dao.add(user);        System.out.println(user.getId() + "successfuly");        User  user2 = dao.get(user.getId());        System.out.println(user2.getName());        System.out.println(user2.getPassword());               // TODO code application logic here    }
