Class SystemPropertiesFactoryBean

java.lang.Object

org.springframework.core.io.support.PropertiesLoaderSupport

org.springframework.beans.factory.config.PropertiesFactoryBean

org.alfresco.config.SystemPropertiesFactoryBean

All Implemented Interfaces:

org.springframework.beans.factory.FactoryBean, org.springframework.beans.factory.InitializingBean

Direct Known Subclasses:

JndiPropertiesFactoryBean

public class SystemPropertiesFactoryBean
extends org.springframework.beans.factory.config.PropertiesFactoryBean

Like the parent PropertiesFactoryBean, but overrides or augments the resulting property set with values from VM system properties. As with the Spring PropertyPlaceholderConfigurer the following modes are supported:

• SYSTEM_PROPERTIES_MODE_NEVER: Don't use system properties at all.
• SYSTEM_PROPERTIES_MODE_FALLBACK: Fallback to a system property only for undefined properties.
• SYSTEM_PROPERTIES_MODE_OVERRIDE: (DEFAULT)Use a system property if it is available.

Note that system properties will only be included in the property set if defaults for the property have already been defined using PropertiesLoaderSupport.setProperties(Properties) or PropertiesLoaderSupport.setLocations(org.springframework.core.io.Resource[]) or their names have been included explicitly in the set passed to SystemPropertiesFactoryBean.setSystemProperties(Set).

resolveMergedProperty

protected void resolveMergedProperty(java.lang.String systemProperty,
                         java.util.Properties props)
