jpa findby with list of conditions - spring

Question

I am still a beginner with java, here I'm trying to fetch the data from mysql database using JPA.
but I'm getting a problem with setting the list of conditions with find by function.
i can set Object of date even it refused the inputs
below is my code for reference.
my query :
select t.id, t.MSISDN, t.Param1, t.param2
from BULK_REPOSITORY t
where t.Camp_Start_Date between Sysdate - 2 and sysdate
and t.status = 0
and t.camp_type = 1;
Application :
#SpringBootApplication
public class AccessingDataJpaApplication {
private static final Logger log = LoggerFactory.getLogger(AccessingDataJpaApplication.class);
Bulk_repository bulk ;
public static void main(String[] args) {
SpringApplication.run(AccessingDataJpaApplication.class);
}
#Bean
public CommandLineRunner demo(Bulk_repositoryRepository repository) {
return (args) -> {
// fetch customers by Status
log.info("Customer found with findByStatus('0'):");
log.info("--------------------------------------------");
repository.findAllByStatusAndCampTypeAndCampStart_dateBetween(1,2,Date,Date-2).forEach(on -> {
log.info(on.toString());
});
};
}
Bulk_repositoryRepository class :
import org.springframework.data.repository.CrudRepository;
public interface Bulk_repositoryRepository extends CrudRepository<Bulk_repository, Long> {
List<Bulk_repository> findAllByStatusAndCampTypeAndCampStart_dateBetween(int status, int campType,Date campStart_dateStart, Date campStart_dateEnd);
Bulk_repository findById(long id);
}
Bulk_repository:
#Entity
#Table(name = "BULK_REPOSITORY")
public class Bulk_repository {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
#Column(name = "id")
private long id;
#Column(name = "msisdn")
private String msisdn;
#Column(name = "camp_start_date")
private Date campStartDate;
#Column(name = "camp_end_date")
private Date campEndDate;
#Column(name = "camp_type")
private int campType;
#Column(name = "camp_cd")
private String camp_cd;
#Column(name = "status")
private int status;
#Column(name = "process_date")
private Date processDate;
#Column(name = "entry_date")
private Date entryDate;
#Column(name = "entry_user")
private String entry_user;
#Column(name = "param1")
private String param1;
#Column(name = "param2")
private String param2;
#Column(name = "param3")
private String param3;
#Column(name = "param4")
private String param4;
#Column(name = "param5")
private String param5;
#Column(name = "error_desc")
private String error_desc;
#Column(name = "fulfilment_status")
private int fulfilment_status;
## getter and setter and ToString

Answer 1

Use this way,
Escape the _ by using an additional underscore
List<Bulk_repository> findAllByStatusAndCamp__typeAndCamp__start__dateBetween(int status, int camp_type,Date camp_start_dateStart, Date camp_start_dateEnd);
I recommond to use this way in your model class. If so you have to change your repository according to this.
#Column(name = "camp_start_date")
private Date campStartDate; // better to use this way
