Configure complex object in xml to inject.

[qiucx]

--------------------------------------------------------------------
AstyanaxContext<Keyspace> context = new AstyanaxContext.Builder()
.forCluster("ClusterName")
.forKeyspace("KeyspaceName")
.withConnectionPoolConfiguration(new ConnectionPoolConfigurationImpl("MyConnectionPool" )
.setPort(9160)
.setSeeds("127.0.0.1:9160")
)
.withConnectionPoolMonitor(new CountingConnectionPoolMonitor())
.buildKeyspace(ThriftFamilyFactory.getInstance());

context.start();
Keyspace keyspace = context.getEntity();
--------------------------------------------------------------------
I need to inject Keyspace instance in spring and need to configure it in applicationContext.xml.
Can anyone tell me how to do it? it is really complex. thanks.

You need to create a FactoryBean for this. Roughly the class should look something like this

public class KeyspaceFactoryBean<Keyspace> implements FactoryBean<Keyspace> {
private String clusterName;
private String keyspaceName;
private String connectionPoolName;
private int portNo;
private String seeds;
public String getSeeds() {
return seeds;
}
public void setSeeds(String seeds) {
this.seeds = seeds;
}
public int getPortNo() {
return portNo;
}
public void setPortNo(int portNo) {
this.portNo = portNo;
}
public void setConnectionPoolName(String name) {
this.connectionPoolName = name;
}
public String getConnectionPoolName() {
return this.connectionPoolName;
}
public String getKeyspaceName() {
return this.keyspaceName;
}
public void setKeyspaceName(String name) {
this.keyspaceName = name;
}
public void setClusterName(String name) {
this.clusterName = name;
}
public String getClusterName() {
return this.clusterName;
}
public Keyspace getObject() throws Exception {
AstyanaxContext<Keyspace> context = new AstyanaxContext.Builder()
.forCluster(clusterName)
.forKeyspace(keyspaceName)
.withConnectionPoolConfiguration(new ConnectionPoolConfigurationImpl(connectionPoolName )
.setPort(portNo)
.setSeeds(seeds)
)
.withConnectionPoolMonitor(new CountingConnectionPoolMonitor())
.buildKeyspace(ThriftFamilyFactory.getInstance());

context.start();
Keyspace keyspace = context.getEntity();
return keyspace;
}
}

now this can be declared inside your XML Configuration like this

<bean id="keyspace" class="KeyspaceFactoryBean">
<property name="clusterName" value="clusterName" />
<property name="keyspaceName" value="keyspaceName" />
<property name="connectionPoolName" value="connectionPoolName" />
<property name="clusterName" value="clusterName" />
<property name="portNo" value="9110" />
<property name="seeds" value="someAppropriateSeedsValue" />
</bean>

As suggested

Hi,

Is there a way to dynamically set KeyspaceFactoryBean properties from the client when it asks the context for a new instance?

Thanks a lot,
