public abstract com.mongodb.Mongo mongo()
                                 throws Exception

Return the Mongo instance to connect to.

Returns:

Throws:

Exception

mongoTemplate

@Bean
public MongoTemplate mongoTemplate()
                            throws Exception

Returns:

Throws:

Exception

mongoDbFactory

@Bean
public SimpleMongoDbFactory mongoDbFactory()
                                    throws Exception

Creates a SimpleMongoDbFactory to be used by the MongoTemplate. Will use the Mongo instance configured in mongo().

Returns:

Throws:

Exception

mongo(), mongoTemplate()

getMappingBasePackage

protected String getMappingBasePackage()

Return the base package to scan for mapped Documents. Will return the package name of the configuration class' (the concrete class, not this one here) by default. So if you have a com.acme.AppConfig extending AbstractMongoConfiguration the base package will be considered com.acme unless the method is overriden to implement alternate behaviour.

Returns:

the base package to scan for mapped Document classes or null to not enable scanning for entities.

getUserCredentials

protected UserCredentials getUserCredentials()

Return UserCredentials to be used when connecting to the MongoDB instance or null if none shall be used.

Returns:

mongoMappingContext

@Bean
public MongoMappingContext mongoMappingContext()
                                        throws ClassNotFoundException

Creates a MongoMappingContext equipped with entity classes scanned from the mapping base package.

Returns:

Throws:

ClassNotFoundException

See Also:

getMappingBasePackage()

isNewStrategyFactory

@Bean
public IsNewStrategyFactory isNewStrategyFactory()
                                          throws ClassNotFoundException

Returns a MappingContextIsNewStrategyFactory wrapped into a CachingIsNewStrategyFactory.

Returns:

Throws:

ClassNotFoundException

customConversions

@Bean
public CustomConversions customConversions()

Register custom Converters in a CustomConversions object if required. These CustomConversions will be registered with the mappingMongoConverter() and mongoMappingContext(). Returns an empty CustomConversions instance by default.

Returns:

must not be null.

mappingMongoConverter

@Bean
public MappingMongoConverter mappingMongoConverter()
                                            throws Exception

Creates a MappingMongoConverter using the configured mongoDbFactory() and mongoMappingContext(). Will get customConversions() applied.

Returns:

Throws:

Exception

See Also:

customConversions(), mongoMappingContext(), mongoDbFactory()

getInitialEntitySet

protected Set<Class<?>> getInitialEntitySet()
                                     throws ClassNotFoundException

Scans the mapping base package for classes annotated with Document.

Returns:

Throws:

ClassNotFoundException
