The goal of this example is to demonstrate how to use multiple namespaces with Spring Data Aerospike.

Using a single namespace with Spring Data Aerospike is pretty straight forward, Configuration comes out-of-the-box, all you need to do is to extend AbstractAerospikeDataConfiguration class and override two methods: getHosts() and nameSpace(). You can see an example of using a single namespace in Simple Web Application Using Java, Spring Boot, Aerospike and Docker .

Using multiple namespaces with Spring Data Aerospike requires a bit of additional code. Create a configuration class per namespace, and in each configuration class do the following:

• extend AbstractAerospikeDataConfiguration
• override both getHosts() and nameSpace()
• create an AerospikeTemplate bean (with unique bean name and method name)
• point the aerospikeTemplateRef property of the @EnableAerospikeRepositories annotation to the name of the newly created AerospikeTemplate bean.

You can see a fully working example in this repository.

The Spring Data Aerospike versions that support multiple namespaces are 3.1.0 and above. Try to use the latest version whenever possible.

<dependency> <groupId>com.aerospike</groupId> <artifactId>spring-data-aerospike</artifactId> <version>4.8.0</version> </dependency> 

If both repositories are located in the same package - same as in this example (AerospikeProductsRepository and AerospikeUsersRepository are both part of the repositories package), then you need to use the includeFilters field of the @EnableAerospikeRepositories annotation on your configuration class pointing to the relevant repository using customized annotations (ProductsRepository and UsersRepository).

Please note that after upgrading to Spring 3 each of multiple AerospikeTemplate beans must contain method with a unique name which should not be called "aerospikeTemplate". Here is a simple example of a correct bean:

@Bean(name = "aerospikeTemplateUsers") public AerospikeTemplate aerospikeTemplateUsers(
