类 SimpleNamingContextBuilder

  • 所有已实现的接口:
    InitialContextFactoryBuilder

    @Deprecated
    public class SimpleNamingContextBuilder
    extends Object
    implements InitialContextFactoryBuilder
    已过时。
    Deprecated as of Spring Framework 5.2 in favor of complete solutions from third parties such as Simple-JNDI
    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 Java EE data access code outside of a Java EE container.

    There are various choices for DataSource implementations:

    • SingleConnectionDataSource (using the same Connection for all getConnection calls)
    • DriverManagerDataSource (creating a new Connection on each getConnection call)
    • Apache's Commons DBCP offers org.apache.commons.dbcp.BasicDataSource (a real pool)

    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.

      • emptyActivatedContextBuilder

        public static SimpleNamingContextBuilder emptyActivatedContextBuilder()
                                                                       throws NamingException
        已过时。
        If no SimpleNamingContextBuilder is already configuring JNDI, create and activate one. Otherwise take the existing activated SimpleNamingContextBuilder, clear it and return it.

        This is mainly intended for test suites that want to reinitialize JNDI bindings from scratch repeatedly.

        返回:
        an empty SimpleNamingContextBuilder that can be used to control JNDI bindings
        抛出:
        NamingException
      • activate

        public void activate()
                      throws IllegalStateException,
                             NamingException
        已过时。
        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).
        抛出:
        IllegalStateException - if there's already a naming context builder registered with the JNDI NamingManager
        NamingException
      • deactivate

        public void deactivate()
        已过时。
        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).

        activate()
      • clear

        public void clear()
        已过时。
        Clear all bindings in this context builder, while keeping it active.
      • bind

        public void bind​(String name,
                         Object obj)
        已过时。
        Bind the given object under the given name, for all naming contexts that this context builder will generate.
        参数:
        name - the JNDI name of the object (e.g. "java:comp/env/jdbc/myds")
        obj - the object to bind (e.g. a DataSource implementation)
