I want to object data into MongoDB using spring and I have hardcoded it. please how to write a schema for that and I have taken it as an example only. I have a different type of categories in it I have taken only clothes. please tell me how to write one schema for a different type of categories and query too.
please find the attachment for your reference
I would recommend going though Spring Data MongoDB documentation for specifics on mapping java objects to MongoDB documents. Your case would look similar to:
@Document
public class Clothes {
@Id
private ObjectId id;
private Men men;
private Women women;
// getters & setters
}
You would need to define each sub class but this should be the gist of it.
What you can do is create a simple POJO (Plain Old Java Object) and with that you can insert that object into the data base. The the following example:
@Document
public class OAuthModel implements Serializable {
@Id
String username;
@Indexed
String oAuthID;
@Indexed
String type;
// Getter and Setters and Construct.
}
When I insert this object in the DB by calling:
OAuthModel authModel = new OAuthModel(username,firebaseToken.getUid(), OAuthHosts.GOOGLE.getType());
oAuthRepo.insert(authModel);
It will then be seen as this in the Database:
Keep in mind this will work no matter what your object looks like, you can have hashmaps etc. The should be a built in serialization.
@Document annotation we tell spring to generate the JSON automatically when we save data in our mongo database. No matter what type of data you have, arrays, double, ints, etc.@Document annotation above the class and then with your repo class do repo.insert(TheObjectYouWant)
