Hi,
Thanks, for your suggestions.
I've done something similar, but injected the client config directly into the
client bean in the application configuration (not via the
HTTPClientConfigFactory). E.g:
@ComponentScan
@EnableAutoConfiguration
public class Application {
@Value( "${riak.pool.host}" ) private String poolHost;
@Value( "${riak.pool.port}" ) private int poolPort;
@Value( "${riak.pool.timeout.connection}" ) private long
poolTimeoutConnection;
@Value( "${riak.pool.timeout.idle}" ) private long poolTimeoutIdle;
@Value( "${riak.pool.timeout.request}" ) private int poolTimeoutRequest;
@Value( "${riak.pool.buffersize}" ) private int poolBufferSize;
@Bean
public static PropertyPlaceholderConfigurer properties(){
PropertyPlaceholderConfigurer ppc = new PropertyPlaceholderConfigurer();
ClassPathResource[] resources = new ClassPathResource[ ]{ new
ClassPathResource( "app.properties" ) };
ppc.setLocations(resources);
ppc.setIgnoreUnresolvablePlaceholders(true);
return ppc;
}
@Bean
@Scope("singleton")
IRiakClient riakClient() throws Exception{
//create a single client connection configuration using the
property file values
Configuration config = (new PBClientConfig.Builder())
.withConnectionTimeoutMillis(poolTimeoutConnection)
.withIdleConnectionTTLMillis(poolTimeoutIdle)
.withRequestTimeoutMillis(poolTimeoutRequest)
.withHost(poolHost)
.withPort(poolPort)
.withSocketBufferSizeKb(poolBufferSize)
.build();
//create the singleton Riak client using the connection
configuration
IRiakClient client = RiakFactory.newClient(config);
return client;
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
I'm not aware of any obvious benefits of one method over the other. If anyone
can enlighten me please do so :)
Thanks,
Simon.

Subject: RE: Riak and Spring
Hello
1) Create a riakClient bean (applicationContext.xml)
<bean id="riakClient" class="com.basho.riak.client.RiakFactory"
factory-method="newClient">
<constructor-arg ref="HTTPClientConfigFactory" />
</bean>
2) create a HTTPClientConfigFactory bean in which you can specify the host
and port:
package com.webapp.util;
import org.apache.http.client.HttpClient;
import org.springframework.beans.factory.FactoryBean;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
import com.basho.riak.client.raw.http.HTTPClientConfig;
@Component
public class HTTPClientConfigFactory implements FactoryBean<HTTPClientConfig> {
@Value("${${environment}.host}")
private String host;
@Value("${${environment}.port}")
private int port;
@Autowired
HttpClient httpClient;
public HTTPClientConfig getObject() throws Exception {
return new
HTTPClientConfig.Builder().withHttpClient(httpClient)
.withHost(host).withPort(port).build();
}
@Override
public Class<?> getObjectType() {
return HTTPClientConfig.class;
}
@Override
public boolean isSingleton() {
return true;
}
@Override
protected void finalize() throws Throwable {
httpClient.getConnectionManager().shutdown();
}
}
3) Use the RiakClient within a service:
@Autowired
private IRiakClient client;
public Name getName(String sname) {
try {
Name name = client.fetchBucket(NAMEBUCKET).execute()
.fetch(sname, Name.class).execute();
if (name == null) {
throw new ResourceNotFoundException(sname);
}
return name;
} catch (UnresolvedConflictException | RiakRetryFailedException
| ConversionException e) {
throw new ServiceUnavailableException(sname);
}
}

Subject: [IE]:Riak and Spring
Hi,
I'm looking at using a Riak backend in a new component.
My current client is a Spring shop. I'm not all that knowledgable about the
intricaies of Spring , so this question many not make sense, but I am hoping to
integrate Riak in a Spring friendly way.
I was looking at the
spring-projects/spring-data-keyvalue<https://github.com/spring-projects/spring-data-keyvalue>
project, but that's been deprecated in favour of
spring-projects/spring-data-riak<https://github.com/spring-projects/spring-data-riak>
which is empty.
Does anyone know of a Spring-Riak integration project that is high quality and
currently active - preferably with excellent documentation and examples ;)
Thanks,
Simon.
