Check if embbed document have data another document: MongoDB - mongodb

Question

I'm learning MongoDB and Mongo Spring, and I have somethings to wonder.
I have a UserInfo document, a user can have multiple roles (document Roles). I insert as a Set, work good. But for the time being, I can insert a role, which not exist in document Roles.
For the example below, I insert roles as ADMIN2, while Document Roles only having "ADMIN", "USER" and "MOD"
I have a document named User:
#Data
#NoArgsConstructor
#AllArgsConstructor
public class User implements UserDetails,Serializable {
#Id
private String id;
private final static String LOGIN_REGEX = "^(?>[a-zA-Z0-9!$&*+=?^_`{|}~.-]+#[a-zA-Z0-9-]+(?:\\\\.[a-zA-Z0-9-]+)*)|(?>[_.#A-Za-z0-9-]+)$";
#NotNull
#Field
#Size(min = 1, max = 50)
private String username;
#NotNull
#Field
//#Pattern(regexp = LOGIN_REGEX)
private String password;
#JsonIgnore
private Set<Roles> roles;
#Override
public Collection<? extends GrantedAuthority> getAuthorities() {
List<GrantedAuthority> authorities = new ArrayList<>();
Set<Roles> role = this.roles;
for(Roles roleItem : roles) {
authorities.add(new SimpleGrantedAuthority(roleItem.getCode()));
}
return authorities;
}
#Override
public boolean isAccountNonExpired() {
return true;
}
#Override
public boolean isAccountNonLocked() {
return true;
}
#Override
public boolean isCredentialsNonExpired() {
return true;
}
#Override
public boolean isEnabled() {
return true;
}
the UserInfo extends User
#Document
#Data
#AllArgsConstructor
#NoArgsConstructor
public class UserInfo extends User implements Serializable {
public UserInfo(String id, #NonNull String username, #NonNull String password, Set<Roles> roles) {
super(id, username, password, roles);
}
#Field
#NotNull
private String firstName;
#NotNull
#Field
private String lastName;
#Transient
#Getter(AccessLevel.NONE)
private String fullname;
#Field
#NotNull
#Email
private String email;
#Field
private String description;
#Field
private String title;
#Field
private String phoneNumber;
#Field
private String lang;
public String getFullname() {
if(StringUtils.isBlank(lang))
if(lang.equals("VI"))
return lastName + " " + firstName;
else
return firstName + " " + lastName;
return null;
}
}
My idea is, a User can have a lot roles (for now, i have "ADMIN", "MOD" and "USER")
Here is document Roles
#Document("roles")
#Data
#AllArgsConstructor
#NoArgsConstructor
public class Roles implements Serializable{
#Id
private String id;
#Field
private String code;
#Field
private String name;
}
Here how the document UserInfo look like:
{
"_id": {
"$oid": "638b72f79c9b3a78b623ea50"
},
"firstName": "truong",
"lastName": "hoang ngoc nghia",
"email": "truonghnn23232",
"title": "Dev",
"lang": "VI",
"username": "truonghnn",
"password": "$2a$10$Jsn1wPMdr.TlS8yyjQ6mF.OBTdrxTuaaDQ8Xz30hSWsKFRuB2bfKW",
"roles": [
{
"code": "ADMIN"
}
],
"_class": "com.example.Auth_ToDo.Domain.UserInfo"
}
So, the issue is, when I input the roles to UserInfo document, I use JSON like this:
"roles" : [
{"code":"ADMIN2"}
]
Everythings is running fine. But as you can see, roles here having value of ADMIN2, which not exist in document Roles (Document Roles having ADMIN, USER and MOD as roles.code)
How can I implement my code, so when I insert into UserInfo document, it check if my role code exist in document Roles? If not, it will return an exception? (I want it to check by default)
I tried to use Embbed Document, as using #DocumentRef, but not working. The result is
=
"roles": [
null
],
"_class": "com.example.Auth_ToDo.Domain.UserInfo"
}
The role returned as null when i input code as "ADMIN"
