How to enable auditing for MongoDB via Annotations in Spring

Question

I wanted to enable some auditing features, such as @CreatedDate. I am not using Spring xml configuration file, so I cannot add mongo:auditing to Spring configuration. I was wondering if there was an alternative way of enable auditing. The following code is the model for user. But whenever I create a user, the date is not stored in the document, so the auditing it's not working. Could someone give me some help?

@Document(collection = "user")
public class User {
    @Id
    private String id;
    @Indexed(unique = true)
    private String email;
    private String name;
    @CreatedDate
    private Date date;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }

Answer 1

Because you are not using configuration via XML, I believe you are using annotations. You own a class like this:

public class MongoConfig extends AbstractMongoConfiguration {...}

Thus, in addition to the annotations you should already have, add: @EnableMongoAuditing

Your configuration class will look like this now:

@Configuration
@EnableMongoRepositories(basePackages="...")
@EnableMongoAuditing
public class MongoConfig extends AbstractMongoConfiguration {...}

I hope this helps!

Answer 2

That's all you need. No subclasses or other stuff.

@Configuration
@EnableMongoAuditing
public class AnyConfig {}

Answer 3

You should write a configuration class in which you can connect to MongoDB database using mongoClient by passing db url. and add the anootaion of @EnableMongoAuditing on top of that class.
