SpringBoot + MongoDB "Cannot resolve reference to bean 'mongoTemplate' while setting bean property 'mongoOperations'"

Question

I am new to Spring Boot, following tutorials to create a simple restAPI using MongoDB, and I keep encountering this same error " Cannot resolve reference to bean 'mongoTemplate' while setting bean property 'mongoOperations' My db is hosted on atlas.

GroceryItem

package com.github.nohgo.grocerylist.models;

import lombok.Builder;
import lombok.Data;
import org.springframework.data.mongodb.core.mapping.Document;
import org.springframework.data.annotation.Id;

@Data
@Builder
@Document(collection = "grocery-item")
public class GroceryItem {

    @Id
    private String id;
    private String name;
    private int quantity;
    private String category;

    @Override
    public String toString() {
        return "GroceryItem [id=" + id + ", name=" + name + ", quantity=" + quantity + ", category=" + category + "]";
    }
}

ItemRepository

package com.github.nohgo.grocerylist.repository;

import com.github.nohgo.grocerylist.models.GroceryItem;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface ItemRepository extends MongoRepository<GroceryItem, String> {
}

ItemService

package com.github.nohgo.grocerylist.service;

import com.github.nohgo.grocerylist.models.GroceryItem;

public interface ItemService {
    String save (GroceryItem item);
}

ItemServiceImpl

package com.github.nohgo.grocerylist.service;

import com.github.nohgo.grocerylist.models.GroceryItem;
import com.github.nohgo.grocerylist.repository.ItemRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class ItemServiceImpl implements ItemService {

    @Autowired
    private ItemRepository itemRepository;
    @Override
    public String save(GroceryItem item) {
        return itemRepository.save(item).getId();
    }
}

ItemController

package com.github.nohgo.grocerylist.controller;

import com.github.nohgo.grocerylist.models.GroceryItem;
import com.github.nohgo.grocerylist.service.ItemService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;

spring.data.mongodb.uri=mongodb+srv://username:[email protected]/
spring.data.mongodb.database=mygrocerylist

spring.mvc.pathmatch.matching-strategy = ANT_PATH_MATCHER

From here I expected to be able to launch my VM and start sending a post request to my api, but instead I am getting this error on startup (only posted a line because block was marked as spam)

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'itemController': Unsatisfied dependency expressed through field 'itemService': Error creating bean with name 'itemServiceImpl': Unsatisfied dependency expressed through field 'itemRepository': Error creating bean with name 'itemRepository' defined in com.github.nohgo.grocerylist.repository.ItemRepository defined in @EnableMongoRepositories declared on MongoRepositoriesRegistrar.EnableMongoRepositoriesConfiguration: Cannot resolve reference to bean 'mongoTemplate' while setting bean property 'mongoOperations'

I know this error is likely just me making some stupid mistake but I am unable to see where I deviate from these tutorials. Any help is appreciated.

Edit:

GroceryListApplication

package com.github.nohgo.grocerylist;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class GroceryListApplication {
    public static void main(String[] args) {
        SpringApplication.run(GroceryListApplication.class, args);
    }
}

Answer 1

Basically that's the issue of dependencies you have used.

For that please replace the below dependencies from pom.xml

        <dependency>
            <groupId>org.mongodb</groupId>
            <artifactId>mongodb-driver-sync</artifactId>
            <version>5.0.0</version>
        </dependency>

with this

 <dependency>
        <groupId>org.javers</groupId>
        <artifactId>javers-spring-boot-starter-mongo</artifactId>
        <version>6.13.0</version>
    </dependency>

please let me know if still issue persist, thanks!
