Class JndiPropertySource

java.lang.Object

org.springframework.core.env.PropertySource<JndiLocatorDelegate>

org.springframework.jndi.JndiPropertySource

public class JndiPropertySource
extends PropertySource<JndiLocatorDelegate>

PropertySource implementation that reads properties from an underlying Spring JndiLocatorDelegate.

By default, the underlying JndiLocatorDelegate will be configured with its "resourceRef" property set to true, meaning that names looked up will automatically be prefixed with "java:comp/env/" in alignment with published JNDI naming conventions. To override this setting or to change the prefix, manually configure a JndiLocatorDelegate and provide it to one of the constructors here that accepts it. The same applies when providing custom JNDI properties. These should be specified using JndiAccessor.setJndiEnvironment(java.util.Properties) prior to construction of the JndiPropertySource.

Note that StandardServletEnvironment includes a JndiPropertySource by default, and any customization of the underlying JndiLocatorDelegate may be performed within an ApplicationContextInitializer or WebApplicationInitializer.

Since:

3.1

Method Detail

getProperty

public java.lang.Object getProperty(java.lang.String name)

Return the value associated with the given name, null if not found.

This implementation looks up and returns the value associated with the given name from the underlying JndiLocatorDelegate. If a NamingException is thrown during the call to JndiLocatorDelegate.lookup(String), returns null and issues a DEBUG-level log statement with the exception message.
