I tried executing the same functions directly in a CommandRunner and it worked

Just looking at the error message, I am a little worried about your use of Set.of(newBusiness). Set.of creates an immutable set, which is probably not what you want in the long run whether it causes this error or not.
I also don't see why your create method compiles, because userUpdated is not defined locally.

Hazelcast getSql().execute() throws Unrecognized client message received with type: 0x210100

I am trying out Hazelcast client-server.
So far, I
Got up hazelcast server members
Create a spring boot application and connected to hazelcast
Inserted/updated/queried Imap in hazelcast instance
Used SQL Predicate to query map objects
Now I am trying to run an sql query on the object (https://docs.hazelcast.com/imdg/latest/sql/distributed-sql) but couldn't make it work. Am I missing something here ? Do I need to do something else ?
My bean
HazelcastInstance hazelcastInstance() {
ClientConfig clientConfig = new ClientConfig();
clientConfig.getUserCodeDeploymentConfig().setEnabled(true);
ClientUserCodeDeploymentConfig distCLConfig = clientConfig.getUserCodeDeploymentConfig();
List<String> classNames = new ArrayList<>();
classNames.add("com.varane.models.Student");
distCLConfig.setEnabled(true).setClassNames(classNames);
return HazelcastClient.newHazelcastClient(clientConfig);
}
My model
package com.varane.models;
import javax.persistence.Entity;
import javax.persistence.Id;
import java.io.Serializable;
/**
* Model class for students
*/
#Entity
public class Student implements Serializable {
#Id
Integer id;
String name;
String contact;
public Student(){}
public Student(Integer id, String name, String contact) {
this.id = id;
this.name = name;
this.contact = contact;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getContact() {
return contact;
}
public void setContact(String contact) {
this.contact = contact;
}
#Override
public String toString() {
return "Student{" +
"id=" + id +
", name='" + name + '\'' +
", contact='" + contact + '\'' +
'}';
}
}
And my controller
#Autowired
private HazelcastInstance hazelcastInstance;
#GetMapping("/sql-test")
void sqlTest(){
SqlService sqlService = hazelcastInstance.getSql();
sqlService.execute("SELECT * FROM student");
}

You should use a compatible version on the client-side. While the 4.x client is mostly compatible with 5.x, the SQL feature was in BETA until 5.0. So you should use 5.0 or newer.
In Spring boot you can just add the following property to override the version, if you are using Maven:
<hazelcast.version>5.1</hazelcast.version>
or Gradle:
ext['hazelcast.version'] = '5.1'

Difficulty in deserializating list of object

I am trying to make a rest call to bankingClient application's getTrans() method from AccountClient application, output returned will be List of Banking so in bankingClient app I made a BankingList pojo containing a field List of Banking and I am passing it to response type in rest template getForObject method but it is giving me error "Cannot deserialize value of type com.p1.pojo.BankingList from Array value"
This is the method in AccountClient which is making a call to BankingClient's "/banking/{ano}" mapping
#GetMapping("/listofTrans/{cid}")
public BankingList getTrans(#PathVariable Integer cid) {
List<Account> a = acc.getByCid(cid);
BankingList b=new BankingList();
for(Account a1:a) {
b = restTemplate.getForObject("http://BankingClient/banking/"+a1.getAno(),BankingList.class);
}
return b;
}
This is the method in Banking Client
#GetMapping("/{ano}")
public List<Banking> getTrans(#PathVariable Integer ano) {
return service.getTrans(ano);
}
This is my Banking class with getters,setters and constructors
public class Banking {
private int trn_no;
private String dateOfTrn;
private int ano;
private double amount;
}
and BankingList class
public class BankingList {
public List<Banking> list
public List<Banking> getList() {
return list;
}
public void setList(List<Banking> list) {
this.list = list;
}
}
and the error I am getting is as follows
com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize value of type `com.p1.pojo.BankingList` from Array value (token `JsonToken.START_ARRAY`)

I am a beginner at this. Any help would be much appreciated.

The getTrans API is returning just the array and not an object containing the array. So use Banking[].class as the type.
#GetMapping("/listofTrans/{cid}")
public Banking[] getTrans(#PathVariable Integer cid) {
List<Account> a = acc.getByCid(cid);
Banking[] items;
for(Account a1:a) {
items = restTemplate.getForObject("http://BankingClient/banking/"+a1.getAno(), Banking[].class);
}
return items;
}
You can use the ObjectMappers constructCollectionType method to construct the collection type and deserialise with that:
#GetMapping("/listofTrans/{cid}")
public List<Banking> getTrans(#PathVariable Integer cid) {
List<Account> a = acc.getByCid(cid);
List<Banking> items = new ArrayList();
ObjectMapper mapper = new ObjectMapper();
CollectionType collectionType = mapper.getTypeFactory().constructCollectionType(List.class, Banking.class);
for(Account a1:a) {
String response = restTemplate.getForObject("http://BankingClient/banking/"+a1.getAno(), String.class);
items = objectMapper.readValue(response, collectionType);
}
return items;
}
But the simplest solution if you can update the getTrans API is to update it to return BankingList instead.
#GetMapping("/{ano}")
public BankingList getTrans(#PathVariable Integer ano) {
BankingList list = new BankingList();
list.setList(service.getTrans(ano));
return list;
}

JPARepository autowired giving null in service

I am creating a web application using Spring boot and JPA.
When I tried debugging the below code, I could see that inside the service, the repository is null. I haven't done an explicit new call for either the service or the repository. I am not sure why this is happening.
The userService seems to have been created fine, but the repository inside it is null.
The exception stack trace I have pasted here is for the call to controller's addUser()
Controller
#RestController
public class UserController {
#Autowired
private UserService userService;
#Autowired
private LoginService loginService;
#RequestMapping(value = "/user", method = RequestMethod.POST)
public void addUser(#RequestBody final User user) {
userService.addUser(user);
}
#RequestMapping(value = "/user/{email}", method = RequestMethod.PUT)
public void updateUser(#RequestBody final User user, #PathVariable final String email) {
if (loginService.isUserAuthentic(user) && user.getEmail().equals(email)) {
userService.updateUser(user);
} else {
throw new AuthenticationFailureException("The user is not authenticated to view records",
HttpStatus.FORBIDDEN);
}
}
#RequestMapping(value = "/user/{email}", method = RequestMethod.DELETE)
public void deleteUser(#RequestBody final User user, #PathVariable final String email) {
if (loginService.isUserAuthentic(user) && user.getEmail().equals(email)) {

HttpStatus.FORBIDDEN);
}
}

Getting Bad request(404) when using DynamoDB with SpringBoot

I am new to DynamoDB and I am getting null (Service: AmazonDynamoDBv2; Status Code: 404; Error Code: null; Request ID: null) error when using DynamoDB with spring boot. The server starts up pretty fine but breaks while making DB call. I have DynamoDB setup on local machine. My Gradle files looks like this:

I can see there are lots of links explaining similar error with 400 error code but nothing for this. I guess I making some mistake while calling the DB.

So after beating around the bushes, I found out that I was giving the db endpoint as http://localhost:8001 instead of http://localhost:8000. I was mistaken with the endpoint of a dynamodb-admin which was running on 8001.
