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.
