↳ | org.springframework.mock.jndi.SimpleNamingContextBuilder |
Simple implementation of a JNDI naming context builder.
Mainly targeted at test environments, where each test case can
configure JNDI appropriately, so that new InitialContext()
will expose the required objects. Also usable for standalone applications,
e.g. for binding a JDBC DataSource to a well-known JNDI location, to be
able to use traditional J2EE data access code outside of a J2EE container.
There are various choices for DataSource implementations:
Typical usage in bootstrap code:
SimpleNamingContextBuilder builder = new SimpleNamingContextBuilder(); DataSource ds = new DriverManagerDataSource(...); builder.bind("java:comp/env/jdbc/myds", ds); builder.activate();Note that it's impossible to activate multiple builders within the same JVM, due to JNDI restrictions. Thus to configure a fresh builder repeatedly, use the following code to get a reference to either an already activated builder or a newly activated one:
SimpleNamingContextBuilder builder = SimpleNamingContextBuilder.emptyActivatedContextBuilder(); DataSource ds = new DriverManagerDataSource(...); builder.bind("java:comp/env/jdbc/myds", ds);Note that you should not call
activate()
on a builder from
this factory method, as there will already be an activated one in any case.
An instance of this class is only necessary at setup time. An application does not need to keep a reference to it after activation.

Register the context builder by registering it with the JNDI NamingManager.
Note that once this has been done, new InitialContext()
will always
return a context from this factory. Use the emptyActivatedContextBuilder()
static method to get an empty context (for example, in test methods).

Clear all bindings in this context builder, while keeping it active.
Simple InitialContextFactoryBuilder implementation, creating a new SimpleNamingContext instance.
Temporarily deactivate this context builder. It will remain registered with the JNDI NamingManager but will delegate to the standard JNDI InitialContextFactory (if configured) instead of exposing its own bound objects.
Call activate()
again in order to expose this context builder's own
bound objects again. Such activate/deactivate sequences can be applied any number
of times (e.g. within a larger integration test suite running in the same VM).
If no SimpleNamingContextBuilder is already configuring JNDI, create and activate one. Otherwise take the existing activate SimpleNamingContextBuilder, clear it and return it.
This is mainly intended for test suites that want to reinitialize JNDI bindings from scratch repeatedly.
