Method Detail

jdbcMappingContext

@Bean
public JdbcMappingContext jdbcMappingContext(Optional<NamingStrategy> namingStrategy,
                                                   JdbcCustomConversions customConversions)

Register a JdbcMappingContext and apply an optional NamingStrategy.

Parameters:

namingStrategy - optional NamingStrategy. Use NamingStrategy.INSTANCE as fallback.

customConversions - see jdbcCustomConversions().

Returns:

must not be null.

jdbcConverter

@Bean
public JdbcConverter jdbcConverter(JdbcMappingContext mappingContext,
                                         NamedParameterJdbcOperations operations,
                                         @Lazy
                                         RelationResolver relationResolver,
                                         JdbcCustomConversions conversions,
                                         Dialect dialect)

Creates a RelationalConverter using the configured jdbcMappingContext(Optional, JdbcCustomConversions). Will get jdbcCustomConversions() applied.

Returns:

must not be null.

See Also:

jdbcMappingContext(Optional, JdbcCustomConversions), jdbcCustomConversions()

jdbcCustomConversions

@Bean
public JdbcCustomConversions jdbcCustomConversions()

Register custom Converters in a JdbcCustomConversions object if required. These JdbcCustomConversions will be registered with the jdbcConverter(JdbcMappingContext, NamedParameterJdbcOperations, RelationResolver, JdbcCustomConversions, Dialect). Returns an empty JdbcCustomConversions instance by default.

Returns:

will never be null.

jdbcAggregateTemplate

@Bean
public JdbcAggregateTemplate jdbcAggregateTemplate(ApplicationContext applicationContext,
                                                         JdbcMappingContext mappingContext,
                                                         JdbcConverter converter,
                                                         DataAccessStrategy dataAccessStrategy)

Register a JdbcAggregateTemplate as a bean for easy use in applications that need a lower level of abstraction than the normal repository abstraction.

Parameters:

applicationContext - for publishing events. Must not be null.

mappingContext - the mapping context to be used. Must not be null.

converter - the conversions used when reading and writing from/to the database. Must not be null.

Returns:

a JdbcAggregateTemplate. Will never be null.

dataAccessStrategyBean

@Bean
public DataAccessStrategy dataAccessStrategyBean(NamedParameterJdbcOperations operations,
                                                       JdbcConverter jdbcConverter,
                                                       JdbcMappingContext context,
                                                       Dialect dialect)

Create a DataAccessStrategy for reuse in the JdbcAggregateOperations and the JdbcConverter. Override this method to register a bean of type DataAccessStrategy if your use case requires a more specialized DataAccessStrategy.

Returns:

will never be null.

jdbcDialect

@Bean
public Dialect jdbcDialect(NamedParameterJdbcOperations operations)

Resolves a JDBC dialect by inspecting NamedParameterJdbcOperations.

Parameters:

operations - the NamedParameterJdbcOperations allowing access to a Connection.

Returns:

Throws:

DialectResolver.NoDialectException - if the Dialect cannot be determined.
