Spring boot Aerospike and Mongo Beans are Conflicting

Question

In my application I am using both Mongo and Aerospike. While creating AerospikeConfig I have to autowire MappingAerospikeConverter and while creating this bean i am getting internal conflicts with bean name.

ERROR

APPLICATION FAILED TO START

Description:

Parameter 1 of constructor in org.springframework.data.aerospike.convert.MappingAerospikeConverter required a single bean, but 3 were found: - org.springframework.data.aerospike.convert.CustomConversions: defined in null - customConversions: defined by method 'customConversions' in class path resource [com/spring/rule/engine/config/RuleEngineConfig.class] - mongoCustomConversions: defined by method 'mongoCustomConversions' in class path resource [org/springframework/boot/autoconfigure/data/mongo/MongoDataConfiguration.class]

Answer 1

With more recent Spring Data Aerospike 5.0.0 it can be even easier: for basic configuration you only need application.properties, and an annotation to enable repositories, like so:

application.properties:

# Aerospike
spring.aerospike.hosts=localhost:3000
spring.data.aerospike.namespace=test

Configuration class:

@Configuration
@EnableAerospikeRepositories(basePackageClasses = AerospikeUserRepository.class)
public class AerospikeConfiguration extends AbstractAerospikeDataConfiguration {

}

From there you can add more properties or override configuration methods like customConverters() or getClientPolicy() if needed. You can look at the demo projects

Answer 2

You don't have to define mappingAerospikeConverter, aerospikeClient and aerospikeCacheManager beans just extend AbstractAerospikeDataConfiguration as described below (you can do the same thing in Mongo's configuration class).

I did manage to use both Aerospike and Mongo in the same project.

Versions I used:

Aerospike:

<dependency>
    <groupId>com.aerospike</groupId>
    <artifactId>spring-data-aerospike</artifactId>
    <version>3.4.1</version>
</dependency>

Mongo (latest):

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

Configuration classes:

Aerospike:

@Configuration
@EnableConfigurationProperties(AerospikeConfigurationProperties.class)
@EnableAerospikeRepositories(basePackageClasses = AerospikeUserRepository.class)
public class AerospikeConfiguration extends AbstractAerospikeDataConfiguration {

    @Autowired
    private AerospikeConfigurationProperties aerospikeConfigurationProperties;

    @Override
    protected Collection<Host> getHosts() {
        return Collections.singleton(new Host(aerospikeConfigurationProperties.getHost(), aerospikeConfigurationProperties.getPort()));
    }

    @Override
    protected String nameSpace() {
        return aerospikeConfigurationProperties.getNamespace();
    }
}

I used an additional configuration properties class for configuration params and then I passed the values in the application.properties file but its not mandatory:

@Data
@Component
@ConfigurationProperties(prefix = "aerospike")
public class AerospikeConfigurationProperties {
    private String host;
    private int port;
    private String namespace;
}

Mongo:

@Configuration
@EnableMongoRepositories(basePackageClasses = MongoUserRepository.class)
public class MongoConfiguration extends AbstractMongoClientConfiguration {

    @Override
    protected String getDatabaseName() {
        return "test";
    }
}

application.properties:

# aerospike
aerospike.host=localhost
aerospike.port=3000
aerospike.namespace=test

# mongo
spring.data.mongodb.username=root
spring.data.mongodb.password=example
spring.data.mongodb.database=test
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
