Constructor Details

RequestHeaderThreadContextListener

public RequestHeaderThreadContextListener()

Initializes a new instance of the RequestHeaderThreadContextListener class without a RequestHeaderContainer.

RequestHeaderThreadContextListener

public RequestHeaderThreadContextListener(@Nonnull
 RequestHeaderContainer requestHeaders)

Initializes a new instance of the RequestHeaderThreadContextListener class with the given requestHeaders.

Parameters:

requestHeaders - The RequestHeaderContainer to use.

Method Details

getPriority

public int getPriority()

Description copied from interface: ThreadContextListener

Returns the priority that defines the order in which listeners are invoked. Smaller priorities are invoked earlier during context initialization and invoked later (reversed initialization order) during context destruction. Negative number must not be used as they are reserved for internal use.

Specified by:

getPriority in interface ThreadContextListener

Returns:

The priority of this listener implementation.

beforeInitialize

public void beforeInitialize(@Nonnull
 ThreadContext threadContext)

Description copied from interface: ThreadContextListener

Invoked before the current ThreadContext is initialized and set. This method can be used, for example, to inherit properties from the parent context.

ThreadContextAccessor.getCurrentContext() returns the old ThreadContext reference.

Specified by:

beforeInitialize in interface ThreadContextListener

Parameters:

threadContext - The ThreadContext that is initialized and will be set.
