Spring Not Mapping Composite Key Entity To Database - spring

I have two entities User and Focus for which I must store a ranking such that a User can have a ranking for many Focus', and a Focus may have many users. To handle this I've followed https://www.baeldung.com/jpa-many-to-many part 3 whereby I have the 2 following classes:
#Entity(name = "UserBaseRatings")
public class Rating {
#EmbeddedId
RatingKey id;
#ManyToOne
#MapsId("userID")
#JoinColumn(name="userID")
private User user;
#ManyToOne
#MapsId("focusID")
#JoinColumn(name="focusID")
private Focus focus;
private BigDecimal baseRating;
protected Rating(){}
public Rating(User user, Focus focus, BigDecimal baseRating) {
this.user = user;
this.focus = focus;
this.baseRating = baseRating;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public Focus getFocus() {
return focus;
}
public void setFocus(Focus focus) {
this.focus = focus;
}
public BigDecimal getBaseRating() {
return baseRating;
}
public void setBaseRating(BigDecimal baseRating) {
this.baseRating = baseRating;
}
}
and
#Embeddable
public class RatingKey implements Serializable {
#Column(name="userID")
private Long userID;
#Column(name="focusID")
private Long focusID;
protected RatingKey(){}
public RatingKey(Long userID, Long focusID) {
this.userID = userID;
this.focusID = focusID;
}
public Long getUserID() {
return userID;
}
public void setUserID(Long userID) {
this.userID = userID;
}
public Long getFocusID() {
return focusID;
}
public void setFocusID(Long focusID) {
this.focusID = focusID;
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
RatingKey ratingKey = (RatingKey) o;
return Objects.equals(userID, ratingKey.userID) &&
Objects.equals(focusID, ratingKey.focusID);
}
#Override
public int hashCode() {
return Objects.hash(userID, focusID);
}
}
The table for UserBaseRatings has a default value of 1 for baseRating such that if a user does not have a rating on the current focus their rating should be 1. I'm running into a problem where if the user hasn't made a rating then the set of Rating's is empty instead of having a rating of 1 for each focus that exists.
User:
public class User {
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private Long userID;
#Column(name = "userHashedPassword")
private String password;
#Column(name = "userName")
private String userName;
#Column(name = "userEmail")
private String email;
//probably being reset
#Transient
private List<String> groups = new LinkedList<>();
#ManyToMany
#JoinTable(name = "UserRoles",
joinColumns = #JoinColumn(
name = "userID"),
inverseJoinColumns = #JoinColumn(
name = "roleID"))
private Set<Role> roles = new HashSet<>();
#OneToMany(mappedBy = "user")
private Set<Rating> ratings;
protected User(){}
public User(String userHashedPassword, String userName, String email, Set<Role> roles){
this.password = userHashedPassword;
this.userName = userName;
this.email = email;
this.roles = roles;
}
public Long getUserId() {
return userID;
}
public void setId(Long userID) {
this.userID = userID;
}
public String getPassword(){
return password;
}
public void setPassword(String password){
this.password = password;
}
public String getUsername() {
return userName;
}
public void setUsername(String name) {
this.userName = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public Set<Role> getRoles() {
return roles;
}
public void setRoles(Set<Role> roles) {
this.roles = roles;
}
public Set<Rating> getRatings() {
return ratings;
}
public void setRatings(Set<Rating> ratings) {
this.ratings = ratings;
}
}
Focus:
#Entity
public class Focus {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private Long focusID;
private String focusCategory;
private String focusName;
private String focusExplanation;
#OneToMany(mappedBy = "focus")
Set<Rating> ratings;
//image
protected Focus(){}
public Focus(String focusCategory, String focusName, String focusExplanation, Set<Rating> ratings){
this.focusCategory = focusCategory;
this.focusName = focusName;
this.focusExplanation = focusExplanation;
this.ratings = ratings;
}
public Long getFocusId() {
return focusID;
}
public void setFocusId(Long focusID) {
this.focusID = focusID;
}
public String getFocusCategory() {
return focusCategory;
}
public void setFocusCategory(String focusCategory) {
this.focusCategory = focusCategory;
}
public String getFocusName() {
return focusName;
}
public void setFocusName(String focusName) {
this.focusName = focusName;
}
public String getFocusExplanation() {
return focusExplanation;
}
public void setFocusExplanation(String focusExplanation) {
this.focusExplanation = focusExplanation;
}
public Set<Rating> getRatings() {
return ratings;
}
public void setRatings(Set<Rating> ratings) {
this.ratings = ratings;
}
}
What am I missing that will allow a User's Ratings to be populated with the default value for each Focus that exists in the database?
Edit: Added #PrePersist and #PreUpdate to the Rating entity:
#Entity(name = "UserBaseRatings")
public class Rating {
#EmbeddedId
RatingKey id;
#ManyToOne
#MapsId("userID")
#JoinColumn(name="userID")
private User user;
#ManyToOne
#MapsId("focusID")
#JoinColumn(name="focusID")
private Focus focus;
private BigDecimal baseRating;
protected Rating(){}
public Rating(User user, Focus focus, BigDecimal baseRating) {
this.user = user;
this.focus = focus;
this.baseRating = baseRating;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public Focus getFocus() {
return focus;
}
public void setFocus(Focus focus) {
this.focus = focus;
}
public BigDecimal getBaseRating() {
return baseRating;
}
public void setBaseRating(BigDecimal baseRating) {
this.baseRating = baseRating;
}
#PrePersist
public void prePersist() {
if(baseRating == null) {
baseRating = BigDecimal.ONE;
}
}
#PreUpdate
public void preUpdate() {
if(baseRating == null) {
baseRating = BigDecimal.ONE;
}
}
}
Changing spring.jpa.hibernate.ddl-auto= from none to update also made no difference.

If you use ORM all default values have to be explicitly declared. It can be done this way
#Entity(name = "UserBaseRatings")
public class Rating {
// ...
private BigDecimal baseRating = BigDecimal.ONE;
// ...
}
or use #PrePersist and #PreUpdate
#Entity(name = "UserBaseRatings")
public class Rating {
// ...
private BigDecimal baseRating;
// ...
#PrePersist
public void prePersist() {
if(baseRating == null) {
baseRating = BigDecimal.ONE;
}
}
#PreUpdate
public void preUpdate() {
if(baseRating == null) {
baseRating = BigDecimal.ONE;
}
}
}

I cannot remove the association in Many To Many bidirectional hibernate

I can't delete the association in the courses_student table of course and student when trying to delete a course, even if I want to cascade delete it does not work for me since there is a foreign key in courses_student, I don't know what the problem is.
I have also tried to remove the association in the courses_student table doing a update.but nothing happened.
DAO
#Override
public boolean deleteCourse(int id) {
Session currentSession = entityManager.unwrap(Session.class);
Courses course = currentSession.load(Courses.class, id);
for(Student student : course.getEstudiantes()) {
course.removeStudent(student);
}
currentSession.delete(course);
if(course.getId() == null)
return true;
else
return false;
}
Courses entity
#Entity
#Table(name = "courses")
public class Courses {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name="id")
private Integer id;
#Column
private String nombre;
#Column
private String descripcion;
#ManyToMany(mappedBy = "courses")
private Set<Student> Estudiantes = new HashSet<Student>();
public Courses() {
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getNombre() {
return nombre;
}
public void setNombre(String nombre) {
this.nombre = nombre;
}
public String getDescripcion() {
return descripcion;
}
public void setDescripcion(String descripcion) {
this.descripcion = descripcion;
}
public Set<Student> getEstudiantes() {
return Estudiantes;
}
public void setEstudiantes(Set<Student> estudiantes) {
Estudiantes = estudiantes;
}
public void removeStudent(Student student) {
this.Estudiantes.remove(student);
student.getCourses().remove(this);
}
}
Student entity
#Entity
#Table(name = "students")
public class Student {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name="id")
private Integer id;
#Column
private String nombre;
#Column
private String apellido;
#Column
private String dni;
#ManyToMany(fetch=FetchType.LAZY,
cascade= {CascadeType.PERSIST, CascadeType.MERGE,
CascadeType.DETACH, CascadeType.REFRESH})
#JoinTable(
name="courses_students",
joinColumns=#JoinColumn(name="id_student"),
inverseJoinColumns=#JoinColumn(name="id_course")
)
private Set<Courses> courses = new HashSet<Courses>();
public Student() {
}
public Student(String nombre, String apellido, String dni) {
this.nombre = nombre;
this.apellido = apellido;
this.dni = dni;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getNombre() {
return nombre;
}
public void setNombre(String nombre) {
this.nombre = nombre;
}

}

this.apellido = apellido;
}

return dni;
}
public void setDni(String dni) {
this.dni = dni;
}
public Set<Courses> getCourses() {
return courses;
}
public void setCourses(Set<Courses> courses) {
this.courses = courses;
}
}
EDIT:
apparently it works for me, trying to update since owner side.
#Override
public boolean deleteCourse(int id) {
Session currentSession = entityManager.unwrap(Session.class);
Courses course = currentSession.load(Courses.class, id);
for(Student student : course.getEstudiantes()) {
student.removeCourse(course);
}
currentSession.update(course);
if(course.getId() == null)
return true;
else
return false;
}
It seems to me that you are missing a cascade configuration of your #ManyToMany annotation on Courses which is actually the one you are updating / deleting. Try the following:
#ManyToMany(mappedBy = "courses", cascade = {CascadeType.PERSIST, CascadeType.MERGE})
private Set<Student> Estudiantes = new HashSet<Student>();
Also, given that you have a bi-directional relationship, you should also remove the Course from each Student courses property.

Why all properties of a Model passed from AOP to controller with other arguments are null

AOP
#Around(
"execution(* net.inter.warp.bridge.controller.*.*(.., net.inter.warp.bridge.model.User)) && " +
"args(.., authenticatedUser)"
)
public Object withAuthenticatedUser(ProceedingJoinPoint joinPoint, User authenticatedUser) throws Throwable {
System.out.println(joinPoint + " -> " + authenticatedUser);
User user = null;
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
if (authentication != null)
user = (User) userService.loadUserByUsername(authentication.getName());
else
throw new UnauthorizedException("err 1");
if (user == null)
throw new UnauthorizedException("err 2");
return joinPoint.proceed(new Object[]{user});
}
Controller (all properties of authenticatedUser are null)
package net.inter.warp.bridge.controller;
#GetMapping("/boxes/{id}")
public ResponseEntity<Box> getBoxById(#PathVariable(value = "id") Long boxId, User authenticatedUser)
throws NoDynamicTableFoundException, ResourceNotFoundException {}
Controller (This works as there is no more parameters except for authenticatedUser)
package net.inter.warp.bridge.controller;
#GetMapping("/boxes/{id}")
public ResponseEntity<Box> getBoxById(User authenticatedUser)
throws NoDynamicTableFoundException, ResourceNotFoundException {}
AOP seems to hate other paramethers... authenticatedUser is not null, every property of authenticatedUser is null.
Model (I am not sure this issue is related to this)

Spring Data JPA - findByAlias vs. findUserByAlias - error with both

I am using spring boot 2 with JPA and Spring Security.
I have a handler method that, depending upon a dropdown, will find all links either similar to a specific title or posted by a specific user. I know my database is set up properly.
I am getting a null pointer exception at this line:
Optional<User> user = userRepository.findUserByAlias("searchTerm");
I have tried changing the method to findByAlias(...) with the same result.
This is the code for my UserRepository:
public interface UserRepository extends JpaRepository<User, Long> {
Optional<User> findByEmail(String email);
Optional<User> findUserByAlias(String alias);
Optional<User> findByAlias(String alias);
}
and this is my handler method wherein the error occurs at this line:
Optional<User> user = userRepository.findUserByAlias("searchTerm");
#GetMapping("/search")
public String showSearchResults(#RequestParam("searchTerm") String searchTerm, #RequestParam("searchBy") String searchBy, Model model) {
System.out.println("INSIDE showSearchResults + searchTerm =" + searchTerm);
List<Link> searchResults;
if(searchBy.equals("user")) {
System.out.println("INSIDE IF EQUALS 'user'");
// get the user by alias
Optional<User> user = userRepository.findUserByAlias("searchTerm");
// if the user is present the find all links by the user id
if (user.isPresent()) {
searchResults = linkRepository.findAllByUser_Id(user.get().getId());
} else {
searchResults = null;
}
}
if(searchBy.equals("title")){
searchResults = linkRepository.findAllByTitleLike("%" + searchTerm + "%");
} else {
searchResults = null;
}
model.addAttribute("searchTerm", new SearchTerm());
model.addAttribute("searchResults", searchResults);
return "search-results";
}
and this is my User class:
#Entity
public class User implements UserDetails {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column

#Column

#Column

}
public void setLastName(String lastName) {

}
public String getFullName() {

}
public void setFullName(String fullName) {
this.fullName = fullName;
}
public String getAlias() {
return alias;
}
public void setAlias(String alias) {
this.alias = alias;
}
public String getConfirmPassword() {
return confirmPassword;
}
public void setConfirmPassword(String confirmPassword) {
this.confirmPassword = confirmPassword;
}
#Override
public Collection<? extends GrantedAuthority> getAuthorities() {

}
#Override
public boolean isAccountNonLocked() {

}
#Override
public boolean isCredentialsNonExpired() {

}
}
So I have two questions:
1.) First and most importantly - why am I getting null pointer exception? I'm at a loss as to how to go about debugging this.
2.) What is the difference between findByAlias and findUserByAlias?
Any advice would be much appreciated.
Thank you for your help,
Marc
How is your userRepository injected into your controller? It seems that is the most likely reason for the null pointer.

[org.hibernate.mapping.Column(authorities)]

I have follow Hibernate error:
"Could not determine type for: java.util.List, at table: user, for columns: [org.hibernate.mapping.Column(authorities)]"
What can cause a problem?
Also, is it possible use it without model role, and set return getAuthority role "USER" by default?
