• setEnvironment

  public void setEnvironment​(Properties environment)

  Set the environment for the JNDI InitialContext.

• getEnvironment

  public Properties getEnvironment()

• execute

  public <T> T execute​(JndiCallback<T> contextCallback)

  createInitialContext()

• getContext

  public Context getContext()
                     throws NamingException

  Obtain a JNDI context corresponding to this template's configuration. Called by execute(org.springframework.jndi.JndiCallback<T>); may also be called directly.

  The default implementation delegates to createInitialContext().

  返回:

  the JNDI context (never null)

  抛出:

  NamingException - if context retrieval failed

  releaseContext(javax.naming.Context)

• releaseContext

  public void releaseContext​(Context ctx)

  Release a JNDI context as obtained from getContext().

  参数:

  ctx - the JNDI context to release (may be null)

  getContext()

• createInitialContext

  protected Context createInitialContext()
                                  throws NamingException

  Create a new JNDI initial context. Invoked by getContext().

  The default implementation use this template's environment settings. Can be subclassed for custom contexts, e.g. for testing.

  返回:

  the initial Context instance

  抛出:

  NamingException - in case of initialization errors

• lookup

  public Object lookup​(String name)
                throws NamingException

  Look up the object with the given name in the current JNDI context.

  参数:

  name - the JNDI name of the object

  返回:

  object found (cannot be null; if a not so well-behaved JNDI implementations returns null, a NamingException gets thrown)

  抛出:

  NamingException - if there is no object with the given name bound to JNDI

• lookup

  public <T> T lookup​(String name,
                      Class<T> requiredType)
               throws NamingException

  Look up the object with the given name in the current JNDI context.

  参数:

  name - the JNDI name of the object

  requiredType - type the JNDI object must match. Can be an interface or superclass of the actual class, or null for any match. For example, if the value is Object.class, this method will succeed whatever the class of the returned instance.

  返回:

  object found (cannot be null; if a not so well-behaved JNDI implementations returns null, a NamingException gets thrown)

  抛出:

  NamingException - if there is no object with the given name bound to JNDI

• bind

  public void bind​(String name,
                   Object object)
            throws NamingException

  Bind the given object to the current JNDI context, using the given name.

  参数:

  name - the JNDI name of the object

  object - the object to bind

  抛出:

  NamingException - thrown by JNDI, mostly name already bound

• rebind

  public void rebind​(String name,
                     Object object)
              throws NamingException

  Rebind the given object to the current JNDI context, using the given name. Overwrites any existing binding.

  参数:

  name - the JNDI name of the object

  object - the object to rebind
