Why do I get a "io.jsonwebtoken.ExpiredJwtException"?

Why do I get a "io.jsonwebtoken.ExpiredJwtException"? - java

I have a problem with my Spring Security JWT Application. I am getting an error because my JWT is expired, but I can't find, where it gets the 2022-04-12 as an expiration date. I can't find a single piece of code, which says that the expiration date is the 2022-04-12. After my understanding, it is creating a new token, each time I am logging in with a new expiration time, which also has to be true, because in my output I get a new token everytime. But because the 2022-04-12 has already passed, I am getting a "io.jsonwebtoken.ExpiredJwtException". So where does it get the 2022-04-12 from???
I am just providing the parts of my code, I think are neccesary, but if you need more code, just let me know!( I am using Spring Security, if that matters)

This is the token used:
eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJmb28iLCJleHAiOjE2NTAwMDIyOTEsImlhdCI6MTY0OTk2NjI5MX0.tzfB0Wy9Dp3Y9pl-5_Oc4gwPClOHlIjE8kHUcgvKhUs
And this is the token (payload) decoded:
{
"sub": "foo",
"exp": 1650002291, (2022-04-15)
"iat": 1649966291
}
This is a
image of the decoded JWT from jwt.io
And this this is the request I use

I made a mistake, while sending the request in Postman. Instead of passing the JWT in the Header I passed it as an Parameter, which of course won't work because I have nothing that extracts the JWT from the URL🤦‍♂️

Spring Boot with Keycloak Null Pointer

I want to enable Keycloak in my Spring Boot REST API APP but without success and i'm still getting null pointer error on any request. I try different configuration of keycloak. App works without Security Config.
Here is my application.properties
keycloak.realm=realm
keycloak.resource=realm-pi
keycloak.public-client=true
keycloak.auth-server-url=http://10.240.1.10:8087/auth/realms/realm/

KeycloakConfigResolver i've added it in sepearate class because when it was in SecurityConfig it causes error with circular dependency.

In the new version for example keycloak 17.0.0. They removed the part from the url "auth".
If you use this version then change in your application.properties next line.
keycloak.auth-server-url=http://10.240.1.10:8087
But if you want to know what is your token_endpoint according your keycloak version then choose your realm -> Realm Settings -> EndPoints and Click on OpenID Endpoint Configuration. You can see all the information.

I am going to be upfront, I am a newb in Java, especially with SpringBoot. I've been aping the Vaadin CRM tutorial application with minor custormization for my needs.
When I try to login, it throws the following error, which I cannot figure out, so again, I am just going to copypaste the entire stacktrace:

The issue is that form1 isn't initialized when you try to add it on line 62.

Here is my code:
BankOCBCDAO
package com.example.repository;
import com.example.model.BankOCBC;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
#Repository
public interface BankOCBCDAO extends JpaRepository<BankOCBC, Integer>{
}
BankCitiBankDAO
package com.example.repository;
import com.example.model.BankCitiBank;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
#Repository
public interface BankCitiBankDAO extends JpaRepository<BankCitiBank, Integer>{
}
PaymentController
package com.example.controller;
import com.example.model.BankCitiBank;
import com.example.model.BankOCBC;
import com.example.service.PaymentService;
import com.example.dto.ApiResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
#RequestMapping(path="/payment")
public class PaymentController {
#Autowired
private PaymentService paymentService;
#PostMapping("/citi")
public ApiResponse addCitiPayment(#RequestBody BankCitiBank bankCitiBank) {
return paymentService.addCitiPayment(bankCitiBank);
}
#PostMapping("/ocbc")
public ApiResponse addOCBCPayment(#RequestBody BankOCBC bankOCBC) {
return paymentService.addOCBCPayment(bankOCBC);
}
}
PaymentService
package com.example.service;
import com.example.model.BankCitiBank;
import com.example.model.BankOCBC;
import com.example.dto.ApiResponse;
public interface PaymentService {
ApiResponse addCitiPayment(BankCitiBank bankCitiBank);
ApiResponse addOCBCPayment(BankOCBC bankOCBC);
}
PaymentServiceImpl
package com.example.service.impl;
import com.example.dto.ApiResponse;
import com.example.model.BankCitiBank;
import com.example.model.BankOCBC;
import com.example.service.PaymentService;
import com.example.repository.BankCitiBankDAO;
import com.example.repository.BankOCBCDAO;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
#Service
public class PaymentServiceImpl implements PaymentService{
#Autowired
private BankOCBCDAO bankOCBCDAO;
private BankCitiBankDAO bankCitiBankDAO;
#Override
public ApiResponse addCitiPayment(BankCitiBank bankCitiBank) {
bankCitiBankDAO.save(bankCitiBank);
return new ApiResponse(200, "CitiBank Payment Successful", null);
}
#Override
public ApiResponse addOCBCPayment(BankOCBC bankOCBC) {
bankOCBCDAO.save(bankOCBC);
return new ApiResponse(200, "OCBC Payment Successful", null);
}
}
Please advise what is wrong in my code. Thanks in advance.
Also can i ask if there any recommendation ways to encrypt the data value obtained from api before added into the database.

You need to add #Autowired to bankCitiBankDAO too:
#Autowired
private BankOCBCDAO bankOCBCDAO;
#Autowired
private BankCitiBankDAO bankCitiBankDAO;
But as field injection is not the best thing todo (https://www.vojtechruzicka.com/field-dependency-injection-considered-harmful/), you should go with constructor injection:
#Service
public class PaymentServiceImpl implements PaymentService{
private BankOCBCDAO bankOCBCDAO;
private BankCitiBankDAO bankCitiBankDAO;
public PaymentServiceImpl(BankOCBCDAO bankOCBCDAO, BankCitiBankDAO bankCitiBankDAO){
this.bankOCBCDAO = bankOCBCDAO;
this.bankCitiBankDAO = bankCitiBankDAO;
}
...
}

Please add the Proper Annotations in Model Class
that will clear the issues.
Reference
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name="bank_id")
private int bankId;

Why do I get a "io.jsonwebtoken.ExpiredJwtException"? - java

I made a mistake, while sending the request in Postman. Instead of passing the JWT in the Header I passed it as an Parameter, which of course won't work because I have nothing that extracts the JWT from the URL🤦‍♂️
