First off I'd like to say I'm new to Java coding and will try my best to explain my problem.

I'm working on a project in Eclipse using the Spring framework and Gradle. It's early in the coding process, but I'm trying to run my program in the console to test and make sure I have no errors. However, when I run as a Java project I keep encountering this error:

It appears that my problem is somewhere in my ShoppingListController, ShoppingListRepository, and my ShoppingList bean. I'll post the code to those below.

ShoppingList bean:

```
    package org.packagename.shopping.beans;

import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

import org.packagename.shopping.DateTimeOffset;

public class ShoppingList {
    //adding in variables per the TDD
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;

    private int userId;
    private String name;
    private String color;
    //created custom class to create a DateTimeOffset since it is a SQL only type of variable
    private DateTimeOffset createdUtc;
    private DateTimeOffset modifiedUtc;

    //getters setters and hash coding and equals for variables
    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public int getUserId() {
        return userId;
    }

    public void setUserId(int userId) {
        this.userId = userId;
    }

    public String getName() {
        return name;
    }

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

    public String getColor() {
        return color;
    }

    public void setColor(String color) {
        this.color = color;
    }

    public DateTimeOffset getCreatedUtc() {
        return createdUtc;
    }

    public void setCreatedUtc(DateTimeOffset createdUtc) {
        this.createdUtc = createdUtc;
    }

    public DateTimeOffset getModifiedUtc() {
        return modifiedUtc;
    }

    public void setModifiedUtc(DateTimeOffset modifiedUtc) {
        this.modifiedUtc = modifiedUtc;
    }

    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + ((color == null) ? 0 : color.hashCode());
        result = prime * result + ((createdUtc == null) ? 0 : createdUtc.hashCode());
        result = prime * result + id;
        result = prime * result + ((modifiedUtc == null) ? 0 : modifiedUtc.hashCode());
        result = prime * result + ((name == null) ? 0 : name.hashCode());
        result = prime * result + userId;
        return result;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        ShoppingList other = (ShoppingList) obj;
        if (color == null) {
            if (other.color != null)
                return false;
        } else if (!color.equals(other.color))
            return false;
        if (createdUtc == null) {
            if (other.createdUtc != null)
                return false;
        } else if (!createdUtc.equals(other.createdUtc))
            return false;
        if (id != other.id)
            return false;
        if (modifiedUtc == null) {
            if (other.modifiedUtc != null)
                return false;
        } else if (!modifiedUtc.equals(other.modifiedUtc))
            return false;
        if (name == null) {
            if (other.name != null)
                return false;
        } else if (!name.equals(other.name))
            return false;
        if (userId != other.userId)
            return false;
        return true;
    }

}

```

ShoppingListController:

```
    package org.packagename.shopping.controller;

import org.elevenfifty.shopping.repository.ShoppingListRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class ShoppingListController {

    @Autowired
    private ShoppingListRepository listRepo;

    @GetMapping("/ShoppingList")
    public String ShoppingList(Model model){
        model.addAttribute("Shopping List", listRepo.findAll());
        return "Shopping_List";
    }
}

```

ShoppingListRepository:

```
    package org.packagename.shopping.controller;

import org.packagenameenter code here.shopping.repository.ShoppingListRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class ShoppingListController {

    @Autowired
    private ShoppingListRepository listRepo;

    @GetMapping("/ShoppingList")
    public String ShoppingList(Model model){
        model.addAttribute("Shopping List", listRepo.findAll());
        return "Shopping_List";
    }
}

```
