mongodb auditing in spring boot for saving createdDate, lastModifiedDate, createdBy, lastModifiedBy

Question

I am using spring boot, therefore I am not using any xml files for configurations. What I have to do is to EnableMongoAuditing for saving createdDate, lastModifiedDate etc while saving data using MongoRepositories.

My model class

@Component
@Document(collection = "CAPPING")
public class TemporaryCapping extends BaseEntity {

    @Field("contract_id")
    private BigInteger contractId;

    @Field("period_id")
    private BigInteger periodId;

    @Field("user_id")
    private BigInteger userId;

    @Field("amount")
    private Double amount;

    @Field("type_of_capping")
    private TypeOfCapping typeOfCapping;

    public BigInteger getContractId() {
        return contractId;
    }

    public void setContractId(BigInteger contractId) {
        this.contractId = contractId;
    }

    public BigInteger getPeriodId() {
        return periodId;
    }

    public void setPeriodId(BigInteger periodId) {
        this.periodId = periodId;
    }

    public BigInteger getUserId() {
        return userId;
    }

    public void setUserId(BigInteger userId) {
        this.userId = userId;
    }

    public Double getAmount() {
        return amount;
    }

    public void setAmount(Double amount) {
        this.amount = amount;
    }

    public TypeOfCapping getTypeOfCapping() {
        return typeOfCapping;
    }

    public void setTypeOfCapping(TypeOfCapping typeOfCapping) {
        this.typeOfCapping = typeOfCapping;
    }


}



public class BaseEntity implements Serializable{

@Id
@Indexed(unique = true)
private BigInteger id;

@CreatedDate
private DateTime createdDate;

@Field("modified_date")
private BigInteger modifiedDate;

public BigInteger getId() {
    return id;
}

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

public DateTime getCreatedDate() {
    return createdDate;
}

public void setCreatedDate(DateTime createdDate) {
    this.createdDate = createdDate;
}

public BigInteger getModifiedDate() {
    return modifiedDate;
}

public void setModifiedDate(BigInteger modifiedDate) {
    this.modifiedDate = modifiedDate;
}

I have used @CreateDate annotation for saving createDate. and I have used jodatime dependency for DateTime

<dependency>
<groupId>joda-time</groupId>
<artifactId>joda-time</artifactId>
<version>2.9.7</version>
</dependency>

spring-data-mongodb is also added in the dependencies.

This is my main application class

 @SpringBootApplication
    @EnableMongoAuditing
   public class Application {

   public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
   }

} 

Where I am wrong in this impelmentation as the date is not getting saved in database? Also I know that for saving @createdBy you need to write AuditorAware bean but for now I am just trying to save createdBy.

Where should @EnableMongoAuditing be used?

Answer 1

In my application I configure through Java code. I use @EnableMongAuditing this way and also create convertes for ZonedDateTime.

@Configuration
@EnableMongoAuditing
@EnableMongoRepositories(basePackages = { BASE_PACKAGE })
public class MongoConfiguration extends AbstractMongoConfiguration {

    public static final String BASE_PACKAGE = "package.with.aggregates";

    @Value("${spring.data.mongodb.uri}")
    private String mongoUri;

    @Value("${spring.data.mongodb.database}")
    private String databaseName;

    @Override
    protected String getDatabaseName() {
        return databaseName;
    }

    @Override
    public Mongo mongo() throws Exception {
        return new MongoClient(new MongoClientURI(mongoUri));
    }

    // Here you must add converters to Joda datetypes. In my solution is ZonedDateTime
    @Override
    public CustomConversions customConversions() {
        List<Converter<?, ?>> converterList = new ArrayList<>();
        converterList.add(new DateToZonedDateTimeConverter());
        converterList.add(new ZonedDateTimeToDateConverter());
        return new CustomConversions(converterList);
    }

    @Override
    protected String getMappingBasePackage() {
        return BASE_PACKAGE;
    }
}

@EnableMongoAuditing 实际上可以放置在配置中的任何位置（@Configuration 注释旁边）
