«Ошибка преобразования фатального сообщения» при получении JSON с Spring RabbitMQ

Question

Я пытаюсь настроить синхронизацию между двумя приложениями Spring с их собственными БД. Мне нужно синхронизировать одну таблицу между ними.

@Configuration
public class ConfigureRabbitMq {

public static final String QUEUE_NAME = "testqueue";
public static final String EXCHANGE_NAME = "testexchange";

@Bean
Queue createQueue(){
    return new Queue(QUEUE_NAME, false);
}

@Bean
TopicExchange exchange(){
    return new TopicExchange(EXCHANGE_NAME);
}

@Bean
Binding binding(Queue q, TopicExchange exchange){
    return BindingBuilder.bind(q).to(exchange).with("test.#");
}

@Bean
public RabbitTemplate rabbitTemplate(final ConnectionFactory connectionFactory) {
    final RabbitTemplate rabbitTemplate = new RabbitTemplate(connectionFactory);
    rabbitTemplate.setMessageConverter(producerJackson2MessageConverter());
    return rabbitTemplate;
}

@Bean
public Jackson2JsonMessageConverter producerJackson2MessageConverter() {
    return new Jackson2JsonMessageConverter();
}
}

И мой контроллер для тестирования sendMessage:

@RestController
public class SendMessageController {

private final RabbitTemplate rabbitTemplate;

public SendMessageController(RabbitTemplate rabbitTemplate) {
    this.rabbitTemplate = rabbitTemplate;
}

@PostMapping("/send/{value}")
public String sendMessage(@PathVariable String value){

    TestModel testModel = new TestModel("Gruppe 1");
    TestSubModel testSubModel = new TestSubModel("Ryan", 21, "IT", 3);
    TestSubModel testSubModel2 = new TestSubModel("Alex", 21, "DATA", 3);
    TestSubModel testSubModel3 = new TestSubModel("Rejwan", 22, "IT", 3);

    testModel.getTestSubModels().add(testSubModel);
    testModel.getTestSubModels().add(testSubModel2);
    testModel.getTestSubModels().add(testSubModel3);

    rabbitTemplate.convertAndSend(ConfigureRabbitMq.EXCHANGE_NAME, "test.springmessages", testModel);

    //rabbitTemplate.convertAndSend(ConfigureRabbitMq.EXCHANGE_NAME, "test.springmessages", value);
    return "We have sent a message: " + value;
}
}

Модели, которые я пытаюсь отправить:

public class TestModel implements Serializable {
private String groupName;

private List<TestSubModel> testSubModels;

public TestModel(String groupName) {
    this.groupName = groupName;
    testSubModels = new ArrayList<>();
}

public String getGroupName() {
    return groupName;
}

public void setGroupName(String groupName) {
    this.groupName = groupName;
}

public List<TestSubModel> getTestSubModels() {
    return testSubModels;
}

public void setTestSubModels(List<TestSubModel> testSubModels) {
    this.testSubModels = testSubModels;
}
}

И:

package com.bachelor2020.chat;

import java.io.Serializable;

public class TestSubModel implements Serializable {

private String name;
private int age;
private String fieldOfStudy;
private int yearOfStudy;

public TestSubModel(String name, int age, String fieldOfStudy, int yearOfStudy) {
    this.name = name;
    this.age = age;
    this.fieldOfStudy = fieldOfStudy;
    this.yearOfStudy = yearOfStudy;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public int getAge() {
    return age;
}

public void setAge(int age) {
    this.age = age;
}

public String getFieldOfStudy() {
    return fieldOfStudy;
}

public void setFieldOfStudy(String fieldOfStudy) {
    this.fieldOfStudy = fieldOfStudy;
}

public int getYearOfStudy() {
    return yearOfStudy;
}

public void setYearOfStudy(int yearOfStudy) {
    this.yearOfStudy = yearOfStudy;
}
}

Служба для получения сообщений в другом приложении:

@Service
public class ReceiveMessageService {

public void handleMessage(Message message){
    System.out.println("HandleMessage: ");
    System.out.println(message.toString());
    System.out.println(message);
}
}

Я получаю следующие ошибки:

2020-04-03 15:25:41.574  WARN 3293 --- [    container-1] ingErrorHandler$DefaultExceptionStrategy : Fatal message conversion error; message rejected; it will be dropped or routed to a dead letter exchange, if so configured: (Body:'{"groupName":"Gruppe 1","testSubModels":[{"name":"Ryan","age":21,"fieldOfStudy":"IT","yearOfStudy":3},{"name":"Alex","age":21,"fieldOfStudy":"DATA","yearOfStudy":3},{"name":"Rejwan","age":22,"fieldOfStudy":"IT","yearOfStudy":3}]}' MessageProperties [headers={__TypeId__=com.bachelor.rabbitmqdemo.TestModel}, contentType=application/json, contentEncoding=UTF-8, contentLength=0, receivedDeliveryMode=PERSISTENT, priority=0, redelivered=false, receivedExchange=testexchange, receivedRoutingKey=test.springmessages, deliveryTag=1, consumerTag=amq.ctag-FzEtStGEJs6xfGoux7_55Q, consumerQueue=testqueue])

Я проверил и подтвердил, что просто отправка простых строк работает, но я просто не могу понять, как разобрать сообщение JSON. Любая помощь будет принята с благодарностью!

Редактировать:

Это моя конфигурация на принимающей стороне. Это приложение будет только слушать, никогда не отправлять никаких сообщений.
