Can't get products by userId from repository - spring

Question

I have 2 tables. One of them called 'products'
#Data
#Entity
#Table(name = "products")
#NoArgsConstructor
public class Product {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
#Column(length = 100)
#NotBlank(message = "Name must be written")
private String name;
#Column(length = 200)
#NotBlank(message = "Provide image (link in this case) of your product")
private String image;
#PositiveOrZero
private int amount;
#Column(length = 250)
#NotBlank(message = "description must be written")
#Size(min = 10, max = 250, message = "description is too long or empty")
private String description;
#PositiveOrZero
private float price;
#ManyToOne
#JoinColumn(name = "type_id")
private ProductType productType;
public Product(#NotBlank String name, String image, int amount, #NotBlank String description,
#PositiveOrZero float price, ProductType productType) {
this.name = name;
this.image = image;
this.amount = amount;
this.description = description;
this.price = price;
this.productType = productType;
}
}
another table is 'users'
#Data
#Entity
#NoArgsConstructor
#Table(name = "users")
public class User {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
#Column(length = 50)
#Size(min = 2, max = 30, message = "enter appropriate amount of letters, min 2")
private String username;
#Column(length = 100)
#Email(message = "Enter a valid email")
#NotBlank(message = "email should have a value")
private String email;
#Column(length = 50)
#NotBlank(message = "password should have a value")
#Size(min = 6, message = "password should at least consist of 6 characters")
private String password;
private boolean enabled;
private String role;
public User(#Size(min = 2, max = 30, message = "enter appropriate amount of letters, min 2")
String username,
#Email(message = "Enter a valid email")
#NotBlank(message = "email should have a value") String email,
#NotBlank(message = "password should have a value")
#Size(min = 6, message = "password should at least consist of 6 characters")
String password, boolean enabled, String role) {
this.username = username;
this.email = email;
this.password = password;
this.enabled = enabled;
this.role = role;
}
}
and also table that include both 'product_user' (many to many relationship)
it looks like this
#Data
#Entity
#Table(name = "product_user")
#AllArgsConstructor
#NoArgsConstructor
public class ProdAndUser{
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
Integer id;
#ManyToOne
#JoinColumn(name = "product_id")
Product product;
#ManyToOne
#JoinColumn(name = "user_id")
User user;
public ProdAndUser(Product product, User user) {
this.product = product;
this.user = user;
}
}
then I tried to get them from prodAndUser repository by UserId or by User as obj:
#Repository
public interface ProdAndUserRepository extends JpaRepository<ProdAndUser, Integer> {
List<ProdAndUser> getProdAndUsersByUserId(Integer id);
List<ProdAndUser> getAllByUser(User user);
}
my controller looks like this:
#ResponseBody
#GetMapping("/findByUsr/{user}")
public List<ProdAndUser> getByUser(#PathVariable User user){
return prodAndUserRepository.getAllByUser(user);
}
error:
{
"timestamp": "2022-02-12T05:52:53.165+00:00",
"status": 404,
"error": "Not Found",
"message": "No message available",
"path": "/Cart/findByUsr"
}
I have tried to find them all by .findAll() and it worked fine. Also another tables work fine on their own

Answer 1

Look at the error it says (404) means something is not right with the path.
The path on the error does not contain user_id.
