Spring Boot "Failed to execute CommandLineRunner Error"

I tried to add One To Many Annotation to my spring boot project, but when I run my project I get "Failed to execute CommandLineRunner " error.
I wanted users in the user's table to have more than one city. So, I tried to add OneToMany Annotation.
You can see the error at the attachment.

The problem you are encountering, more specifically the NullPointerException at line 54 of your main application, is caused by the fact that the cityRepository is not
instantiated.
Looking through your configuration, I see that you only register the UserRepository with the #EnableJpaRepositories annotation.
Try adding also the CityRepository to the #EnableJpaRepositories, and also specify this bean as a candidate for autowiring( also add #Autowired to this bean, as you did for UserRepository)
For a good practice, following the MVC structure, it would be nice is all your spring repositories, the beans responsible for all CRUD operations with the database to be under the same package

DeleteById Not working in Spring boot JPA Repository

I have two entities- User and Notes. One User can have multiple Notes. I am trying to implement a soft delete for both the tables. For the User table, it is working fine but for Notes table, calling deleteById is not changing the value of the deleted column to true. I tried returning findById(notesId) and it's returning right row but delete is not working.

Try with #NamedQuery instead of #SQLDelete
or
try with
repo.deleteInBatch(list)

Problems with #ManyToMany Annotation Hibernate - Foreign key has the wrong number of column (should be 3)

I want to add the following database-structure to my Jpa:
CREATE TABLE USER (
id int PRIMARY KEY AUTO_INCREMENT,
firstname varchar(255),
lastname varchar(255)
);
CREATE TABLE PROJECT (
PNUM varchar(255) PRIMARY KEY,
PNAME varchar(255) NOT NULL
);
CREATE TABLE ROLE (
id int PRIMARY KEY AUTO_INCREMENT,
description varchar(255) NOT NULL
);
CREATE TABLE ASSIGNMENT (
user_id int,
project_num varchar(255),
role_id int,
foreign key (user_id) REFERENCES USER(ID),
FOREIGN KEY (project_num) REFERENCES PROJECT(PNUM),
FOREIGN KEY (role_id) REFERENCES ROLE(id),
PRIMARY KEY (user_id, project_num, role_id)
);
So I started off making the three Entities User, Project and Role (See end of this post for full classes). Then I created the Assignment-class for the connection including an #EmbeddedId:
The Assigment class:
package com.demo.example.entity;
import javax.persistence.EmbeddedId;
import javax.persistence.Entity;
#Entity
public class Assignment {
#EmbeddedId
private AssignmentId id;
public Assignment() {
// TODO Auto-generated constructor stub
}
public AssignmentId getId() {
return this.id;
}
public void setId(AssignmentId id) {
this.id = id;
}
}
The AssignmentId-class
package com.demo.example.entity;
import java.io.Serializable;
import javax.persistence.Embeddable;
#Embeddable
public class AssignmentId implements Serializable {
private Role role;
private Project project;
private User user;
public AssignmentId(Project project, Role role, User user) {
this.project = project;
this.role = role;
this.user = user;
}
public Project getProject() {
return project;
}
public void setProject(Project project) {
this.project = project;
}
public Role getRole() {
return role;
}
public void setRole(Role role) {
this.role = role;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
Finally I declared the repository for the Assignment:
package com.demo.example.repository;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
import com.demo.example.entity.Assignment;
import com.demo.example.entity.AssignmentId;
#Repository
public interface AssignmentRepository extends JpaRepository<Assignment, AssignmentId> {
}
Now upon running a JUnit-Test I run into the following error:
Caused by: org.hibernate.AnnotationException: A Foreign key refering com.demo.example.entity.Assignment from com.demo.example.entity.User has the wrong number of column. should be 3
I have seen quite a few suggestions on what to do but none of them worked (also, most of the time the "should be"-value is 2. Is this even working out with 3?). But I cannot make out why my User-Entity has a wrong number of columns? It provided three in the #JoinTable-Annotation (one join and two inverseJoin-Columns). What did I do wrong?
