DAO instance not working in service class - NullPointerException - spring

Question

In my spring boot project I created a Repository interface (which extends CRUDRepository) and an Entity class of the Table in my DB.
This is my Repo:
#Repository
public interface AuthPaymentDao extends CrudRepository<TFraudCard,String> {
#Query("SELECT t FROM TFraudCard t where t.tokenNumber = (?1)")
TFraudCard findByTokenNumber(String tokenNumber);
}
This is my Entity Class (TOKEN_NUMBER is the primary Key in the TFRAUDCARD TABLE):
#Entity
#Table(name = "TFRAUDCARD")
public class TFraudCard {
#Id
#Column(name="TOKEN_NUMBER")
private String tokenNumber;
#Column(name="TRANSACTIONNUMBER")
private int transactionNumber;
#Column(name="CARDNUMBER")
private int cardNumber;
#Column(name="DATEADDED", insertable = false, updatable = false, nullable = false)
private Timestamp dateAdded;
#Column(name="CALLINGENTITY", nullable = false)
private String callingEntity;
#Column(name="ACCOUNTID")
private String accountId;
#Column(name="ROUTINGNUMBER")
private String routingNumber;
#Column(name="BANKACCOUNTNUMBER")
private String bankAccountNumber;
#Column(name="COMMENTS")
private String comments;
#Column(name="USERID")
private String userId;
#Column(name="REMOVEDATE")
private Timestamp removeDate;
public String getTokenNumber() {
return tokenNumber;
}
public void setTokenNumber(String tokenNumber) {
this.tokenNumber = tokenNumber;
}
public int getTransactionNumber() {
return transactionNumber;
}
public void setTransactionNumber(int transactionNumber) {
this.transactionNumber = transactionNumber;
}
public int getCardNumber() {
return cardNumber;
}
public void setCardNumber(int cardNumber) {
this.cardNumber = cardNumber;
}
public Timestamp getDateAdded() {
return dateAdded;
}
public void setDateAdded(Timestamp dateAdded) {
this.dateAdded = dateAdded;
}
public String getCallingEntity() {
return callingEntity;
}
public void setCallingEntity(String callingEntity) {
this.callingEntity = callingEntity;
}
public String getAccountId() {
return accountId;
}
public void setAccountId(String accountId) {
this.accountId = accountId;
}
public String getRoutingNumber() {
return routingNumber;
}
public void setRoutingNumber(String routingNumber) {
this.routingNumber = routingNumber;
}
public String getBankAccountNumber() {
return bankAccountNumber;
}
public void setBankAccountNumber(String bankAccountNumber) {
this.bankAccountNumber = bankAccountNumber;
}
public String getComments() {
return comments;
}
public void setComments(String comments) {
this.comments = comments;
}
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
public Timestamp getRemoveDate() {
return removeDate;
}
public void setRemoveDate(Timestamp removeDate) {
this.removeDate = removeDate;
}
public TFraudCard() {
super();
}
public TFraudCard(String tokenNumber, int transactionNumber, int cardNumber, Timestamp dateAdded,
String callingEntity, String accountId, String routingNumber, String bankAccountNumber, String comments,
String userId, Timestamp removeDate) {
super();
this.tokenNumber = tokenNumber;
this.transactionNumber = transactionNumber;
this.cardNumber = cardNumber;
this.dateAdded = dateAdded;
this.callingEntity = callingEntity;
this.accountId = accountId;
this.routingNumber = routingNumber;
this.bankAccountNumber = bankAccountNumber;
this.comments = comments;
this.userId = userId;
this.removeDate = removeDate;
}
#Override
public String toString() {
return "TFraudCard [tokenNumber=" + tokenNumber + ", transactionNumber=" + transactionNumber + ", cardNumber="
+ cardNumber + ", dateAdded=" + dateAdded + ", callingEntity=" + callingEntity + ", accountId="
+ accountId + ", routingNumber=" + routingNumber + ", bankAccountNumber=" + bankAccountNumber
+ ", comments=" + comments + ", userId=" + userId + ", removeDate=" + removeDate + "]";
}
}
My Service Class:
Autowiring the DAO instance inside my Service Class:
Implementing the DAO instance inside a Method in the Service Class:
private void fraudCheck(PaymentDetail paymentDetail) throws RegularPaymentBusinessException {
logger.info("INSIDE FRAUD CHECK METHOD");
String pmtInd=paymentDetail.getPmtInd();
logger.info("pmtInd: " + pmtInd);
String tokenizedCardNum=paymentDetail.getTokenizedCardNum();
logger.info("tokenizedCardNum: " + tokenizedCardNum);
if(pmtInd.equalsIgnoreCase(VepsConstants.GIFT_CARD_IDENTIFIER) || pmtInd.equalsIgnoreCase(VepsConstants.CREDIT_CARD_IDENTIFIER) || pmtInd.equalsIgnoreCase(VepsConstants.DEBIT_CARD_IDENTIFIER)) {
logger.info("INSIDE CARD CHECK");
TFraudCard fraudCard = authPaymentDao.findByTokenNumber(tokenizedCardNum);
logger.info("fraudCard Details: " + fraudCard.toString());
if(fraudCard!=null) {
logger.info("INSIDE EXCEPTION FLOW FOR CARD FRAUD CHECK");
throw new RegularPaymentBusinessException(VepsConstants._9966, VepsConstants._9966_MESSAGE, VepsConstants.FAILURE);
}
}
}
Even though I pass the same token Number (tokenizedCardNumber) in my method as the data in the TOKEN_NUMBER column of my TFRAUDCARD table I still get a NullPointerException when I try to print a toString() of the Entity Object.
Here is the NullPointerException on my cloudFoundry logs (Click on it to see zoomed image) :
I'm providing the DB details in my dev properties file:
I have gone over every scenario in my head for why it breaks but I still can't come up with an answer. I'm using my variable marked with #Id i.e. the Primary Key for my find() method in the Repository.
I'm also adding a #Query annotation just to be even more specific.
It still does not work.
