filterAndCopyHeadersIfAbsent

public AbstractIntegrationMessageBuilder<T> filterAndCopyHeadersIfAbsent(Map<String,?> headersToCopy,
 @Nullable
 String... headerPatternsToFilter)

Remove headers from the provided map matching to the provided pattens and only after that copy the result into the target message headers.

Parameters:

headersToCopy - a map of headers to copy.

headerPatternsToFilter - an arrays of header patterns to filter before copying.

Returns:

the current AbstractIntegrationMessageBuilder.

5.1

setHeader

public abstract AbstractIntegrationMessageBuilder<T> setHeader(String headerName,
 @Nullable
 Object headerValue)

Set the value for the given header name. If the provided value is null, the header will be removed.

Parameters:

headerName - The header name.

headerValue - The header value.

Returns:

this.

setHeaderIfAbsent

public abstract AbstractIntegrationMessageBuilder<T> setHeaderIfAbsent(String headerName,
 Object headerValue)

Set the value for the given header name only if the header name is not already associated with a value.

Parameters:

headerName - The header name.

headerValue - The header value.

Returns:

this.

removeHeaders

public abstract AbstractIntegrationMessageBuilder<T> removeHeaders(String... headerPatterns)

Removes all headers provided via array of 'headerPatterns'. As the name suggests the array may contain simple matching patterns for header names. Supported pattern styles are: "xxx*", "*xxx", "*xxx*" and "xxx*yyy".

Parameters:

headerPatterns - The header patterns.

Returns:

this.

removeHeader

public abstract AbstractIntegrationMessageBuilder<T> removeHeader(String headerName)

Remove the value for the given header name.

Parameters:

headerName - The header name.

Returns:

this.

copyHeaders

public abstract AbstractIntegrationMessageBuilder<T> copyHeaders(@Nullable
 Map<String,?> headersToCopy)

Copy the name-value pairs from the provided Map. This operation will overwrite any existing values. Use { copyHeadersIfAbsent(Map) to avoid overwriting values. Note that the 'id' and 'timestamp' header values will never be overwritten.

Parameters:

headersToCopy - The headers to copy.

Returns:

this.

See Also:

• MessageHeaders.ID
• MessageHeaders.TIMESTAMP

copyHeadersIfAbsent

public abstract AbstractIntegrationMessageBuilder<T> copyHeadersIfAbsent(@Nullable
 Map<String,?> headersToCopy)

Copy the name-value pairs from the provided Map. This operation will not overwrite any existing values.

Parameters:

headersToCopy - The headers to copy.

Returns:

this.
