Help to solve the problem, I cannot make a request to the second application through the eureka service.
Here is my code:

I am learning unit testing. I have implemented unit test for the spring boot controller in my sample project. When I run the test class, every time it returns 400 status (Expected 200). After i did a research and I have found that if(entity.getStatusCode().equals(HttpStatus.OK)) { is line which gives exception. It might be because it uses return of Service2.
However, code is working fine without running test cases. I have attached MyController and MyControllerTest classes.
My Controller
#RestController
#RequestMapping("/user")
public class UserController {
private static final Logger LOGGER = LoggerFactory.getLogger(UserController.class);
#Autowired
private UserManagementService userManageService;
#Autowired
private AdminManagementService adminManageService;
#Autowired
private AuthenticateManagementService authService;
#PutMapping("/change-password")
public ResponseEntity<?> changePassword(#RequestHeader("Authorization") String token,
#RequestBody PasswordChangeRequestDTO passwordChangeRequestDTO) {
ResponseDTO finalResponse = new ResponseDTO();
try {
LOGGER.info("Changing user password.");
KeycloakLoginResponseDTO keycloakResponse = authService.auhtenticate(passwordChangeRequestDTO.getLoginRequestDTO());
ResponseEntity<?> logoutEntity = authService.logout(token, keycloakResponse.getSession_state());
if(logoutEntity.getStatusCode().equals(HttpStatus.OK)) {
LOGGER.info("User password matched");
}
String userId = adminManageService.getUserByName(token, passwordChangeRequestDTO.getLoginRequestDTO().getUsername());
ResponseEntity<?> entity = userManageService.changePassword(token, passwordChangeRequestDTO, userId);
LOGGER.info("USER : " + "" +"has successfully changed password.");
finalResponse.setMessageCode(HttpStatus.OK);
finalResponse.setMessage("Password changed successfully");
finalResponse.setError(false);
ResponseEntity<ResponseDTO> finalEntity = ResponseEntity.ok().body(finalResponse);
return finalEntity;
}catch (Exception e) {
e.printStackTrace();
LOGGER.error("Error has occured while changing password of USER : " + "" + ".");
finalResponse.setMessageCode(HttpStatus.EXPECTATION_FAILED);
finalResponse.setMessage("Oops! Looks like you have entered the wrong password in the 'Old Password' field");
finalResponse.setMessageDetail(e.getMessage());
finalResponse.setError(true);
ResponseEntity<ResponseDTO> finalEntity = ResponseEntity.badRequest().body(finalResponse);
return finalEntity;
}
}
}

What am i doing wrong here. Is there anything to add to my MyControllerTest class or How can i cover this test case. Any help would be grateful.
UPDATED
I have also added e.printStackTrace()

I cannot resolve the following serialization issue that is triggered by filtered.foreachPartition(iter => {. I though that foreachPartition can resolve serialization problem, but it's not the case. So, how to use redisPool?
EDIT (I updated the code to make it more clear):
val redis_host = "localhost"
val redist_port = 6379
messages.foreachRDD(rdd => {
rdd.foreachPartition(iter => {
val redisPool = new Pool(new JedisPool(new JedisPoolConfig(), redis_host, redis_port, 2000))
iter.foreach({ msg =>
println(msg.mkString(","))
})
})
})
I assume that the variables redis_host and redis_port are not serializable, but how do I serialize them correctly so that the code can work on the cluster, not only locally?
The above-shown code throws the error:

The solution is to initialise the pool lazily inside your anonymous function. In java you could do something like this:
messages.foreachRDD(new RedisFunction(redis_host, redis_port))
messages.count()
class RedisFunction implements F {
private Pool pool = null;
private final String redis_host;
private final String redis_port;
RedisFunction(String redis_host, String redis_port) {
this.redis_host = redis_host;
this.redis_port = redis_port;
initPool();
}
private void initPool() {
this.pool = new Pool(new JedisPool(new JedisPoolConfig(), redis_host, redis_port, 2000))
}
public Void call(JavaRDD<> rdd) {
if(this.pool == null) {
initPool();
}
rdd = rdd.map(....); /*your rdd transformations go here*/
rdd.count(); //spark action
}
}
Above java example should help you to fix the serialisation issue.
I have a session called an OrderManager. This session is used to collect orders from a form (thorough a controller) and post it in the database. My OrderManager is acting strange and I'd really appreciate some help. Persist works for one part and throws an exception for the next (according to the debugger).
main method (working):
public int placeOrder(String name, String email, String phone, String address, String cityRegion, String ccNumber, ShoppingCart cart) {
try {
Customer customer = addCustomer(name, email, phone, address, cityRegion, ccNumber);
CustomerOrder order = addOrder(customer, cart);
addOrderedItems(order, cart);
return order.getId();
} catch (Exception e) {
context.setRollbackOnly();
return 0;
}
}
Customer method (also working):
private Customer addCustomer(String name, String email, String phone, String address, String cityRegion, String ccNumber) {
Customer customer = new Customer();
customer.setName(name);
customer.setEmail(email);
customer.setPhone(phone);
customer.setAddress(address);
customer.setCityRegion(cityRegion);
customer.setCcNumber(ccNumber);
em.persist(customer);
return customer;
}
CustomerOrder method (stops at em.persist(order) and throws exception):
private CustomerOrder addOrder(Customer customer, ShoppingCart cart) {
// set up customer order
CustomerOrder order = new CustomerOrder();
order.setCustomer(customer);
order.setAmount(BigDecimal.valueOf(cart.getTotal()));
// create confirmation number
Random random = new Random();
int i = random.nextInt(999999999);
order.setConfirmationNumber(i);
em.persist(order);
return order;
}
Please help me as soon as possible. Thank you.

Severe: PWC6117: File "null" not found
I've got a simple Rest Controller that returns ResponseEntity<Void>. I'm trying to call it though Feign client and getting NPE while decoding the result. Spring cloud version: Angel.SR3, Feign version: 8.9.0
Changing the return value to ResponseEntity<String> and passing some dummy value solves the problem, but is it supposed to work with Void return type?

RestController:
#RestController
public class TestResource {
#RequestMapping(value = "/test", method = RequestMethod.GET, consumes="application/json", produces="application/json")
ResponseEntity<Void> testPost() {
return new ResponseEntity<>(HttpStatus.OK);
}
}
Feign Client to access the rest resource:
#FeignClient("order-service")
public interface TestClient {
#RequestMapping(value = "/test", method = RequestMethod.GET, consumes="application/json", produces="application/json")
ResponseEntity<Void> testGet();
}
Call of the feign client:
#Service
public class Test {
#Autowired
private TestClient testClient;
void test() {
testClient.testGet(); // this line triggers NPE
}
}
The issue is fixed on the 1.0.x line and will be in Angel.SR4, it already worked in Brixton.M1, but I forward ported the test. See https://github.com/spring-cloud/spring-cloud-netflix/issues/539 for the commits.
