Could you please let me know the problem in below code?
- Role entity class (for Role table) - in this class i have "Set userRoles" and in the getter of this userRoles i have @OneToMany(mappedBy = "role")
- User entity class (for User table) - in this class i have "Set userRoles" and in the getter of this userRoles i have @OneToMany(mappedBy = "user")
- UserRole entity class (for UserRole table) - in this class i have
3.1 "Role role" and in the getter of this role i have "@ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL) @JoinColumn(name = "role_id")"
3.2 "User user" and in the getter of this user i have @ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL) @JoinColumn(name = "user_id")"
3.3 Also "BigInteger userRoleId" is the primary key of this table
Now when i run this to find the user by name, i get the result json in which user json contains userRoles which contains role which again contains userRoles and this repetition of userRoles and roles goes on and on indefinitely. Could you please help me why this repetition is happening?
