Class CassandraMappingBeanFactoryPostProcessor

java.lang.Object

org.springframework.data.cassandra.config.CassandraMappingBeanFactoryPostProcessor

All Implemented Interfaces:

BeanFactoryPostProcessor, BeanDefinitionRegistryPostProcessor

public class CassandraMappingBeanFactoryPostProcessor
extends Object
implements BeanDefinitionRegistryPostProcessor

BeanDefinitionRegistryPostProcessor that does its best to register any missing Spring Data Cassandra beans that can be defaulted. Specifically, it attempts to create default bean definitions for the following required interface types via their default implementation types:

• CassandraOperations via CassandraTemplate
• CassandraMappingContext via BasicCassandraMappingContext
• CassandraConverter via MappingCassandraConverter

If there are multiple definitions for any type that another type depends on, an IllegalStateException is thrown. For example, if there are two definitions for type CassandraMappingContext present and no definition for type CassandraConverter, then it's impossible to know which CassandraMappingContext is to be used when creating a default definition for the CassandraConverter.

If a single definition of a required type is present, then it is used. For example, if there is already a CassandraMappingContext definition present, then it will be used in the BasicCassandraMappingContext bean definition.

It requires that a single Session or CassandraSessionFactoryBean definition be present. As described above, multiple Session definitions, multiple CassandraSessionFactoryBean definitions, or both a Session and CassandraSessionFactoryBean will cause an IllegalStateException to be thrown.
