java.lang.Object
  org.springframework.core.io.support.PropertiesLoaderSupport
      org.springframework.beans.factory.config.PropertyResourceConfigurer
          org.springframework.beans.factory.config.PropertyPlaceholderConfigurer
              org.openspaces.core.cluster.ClusterInfoPropertyPlaceholderConfigurer

All Implemented Interfaces:

ClusterInfoAware, BeanFactoryAware, BeanNameAware, BeanFactoryPostProcessor, Ordered, PriorityOrdered

public class ClusterInfoPropertyPlaceholderConfigurer
extends PropertyPlaceholderConfigurer
implements BeanNameAware, BeanFactoryAware, ClusterInfoAware

Provides the ClusterInfo parameters as injected properties that can be used within Spring application context. The following is a list of the properties:

• ${clusterInfo.numberOfInstances} : Maps to ClusterInfo.getNumberOfInstances()
• ${clusterInfo.numberOfBackups} : Maps to ClusterInfo.getNumberOfBackups()
• ${clusterInfo.instanceId} : Maps to ClusterInfo.getInstanceId()
• ${clusterInfo.backupId} : Maps to ClusterInfo.getBackupId()
• ${clusterInfo.schema} : Maps to ClusterInfo.getSchema()
• ${clusterInfo.runningNumber} : Maps to ClusterInfo.getRunningNumber()
• ${clusterInfo.suffix} : Maps to ClusterInfo.getSuffix()
• ${clusterInfo.name} : Maps to ClusterInfo.getName()

If the cluster info parameter is not set (has null value) an empty string will be used.

Method Detail

createProperties

public static Properties createProperties(ClusterInfo clusterInfo)

setClusterInfo

public void setClusterInfo(ClusterInfo clusterInfo)

Description copied from interface: ClusterInfoAware

Sets the cluster information.

Note, the cluster information is obtained externally from the application context which means that this feature need to be supported by specific containers (and is not supported by plain Spring application context). This means that beans that implement ClusterInfoAware should take into account the fact that the cluster info provided might be null.

Specified by:

setClusterInfo in interface ClusterInfoAware

Parameters:

clusterInfo - The cluster information to be injected

setBeanName

public void setBeanName(String beanName)

Specified by:

setBeanName in interface BeanNameAware

Overrides:

setBeanName in class PropertyPlaceholderConfigurer

setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)

Specified by:

setBeanFactory in interface BeanFactoryAware

Overrides:

setBeanFactory in class PropertyPlaceholderConfigurer

processProperties

protected void processProperties(ConfigurableListableBeanFactory beanFactoryToProcess,
                                 Properties props)
                          throws BeansException

Overrides:

processProperties in class PropertyPlaceholderConfigurer

Throws:

BeansException
