Method Detail

session

@Bean
public CassandraSessionFactoryBean session()
                                          throws ClassNotFoundException

Creates a CassandraSessionFactoryBean that provides a Cassandra Session. The lifecycle of CassandraSessionFactoryBean initializes the schema in the configured keyspace.

Returns:

the CassandraSessionFactoryBean.

Throws:

ClassNotFoundException - if an error occurs initializing the initial entity set, see cassandraMapping()

cassandraConverter

@Bean
public CassandraConverter cassandraConverter()
                                            throws ClassNotFoundException

Creates a CassandraConverter using the configured cassandraMapping(). Will apply all specified customConversions().

Returns:

CassandraConverter used to convert Java and Cassandra value types during the mapping process.

Throws:

ClassNotFoundException - if an error occurs initializing the initial entity set, see cassandraMapping()

See Also:

cassandraMapping(), customConversions()

customConversions

@Bean
public CustomConversions customConversions()

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

Returns:

must not be null.

Since:

1.5

cassandraMapping

@Bean
public CassandraMappingContext cassandraMapping()
                                               throws ClassNotFoundException

Return the MappingContext instance to map Entities to properties.

Throws:

ClassNotFoundException - if the Cassandra Entity class type identified by name cannot be found during the scan.

See Also:

CassandraMappingContext

cassandraTemplate

@Bean
public CassandraAdminOperations cassandraTemplate()
                                                 throws Exception

Creates a CassandraAdminTemplate.

Throws:

Exception - if the Session could not be obtained.

setBeanClassLoader

public void setBeanClassLoader(ClassLoader classLoader)

Specified by:

setBeanClassLoader in interface BeanClassLoaderAware

getEntityBasePackages

public String[] getEntityBasePackages()

Base packages to scan for entities annotated with Table annotations. By default, returns the package name of this (this.getClass().getPackage().getName(). This method must never return null.

getKeyspaceName

protected abstract String getKeyspaceName()

Return the name of the keyspace to connect to.

Returns:

must not be null.

getSchemaAction

public SchemaAction getSchemaAction()

The SchemaAction to perform at startup. Defaults to SchemaAction.NONE.
