Method Details

selectorExpression

public S selectorExpression(String selectorExpression)

Configure a SpEL expression to select messages. The root object for the expression evaluation is a MimeMessage which should return a boolean result (true means select the message).

Parameters:

selectorExpression - the selectorExpression.

Returns:

the spec.

assertReceiver

protected void assertReceiver()

selectorExpression

public S selectorExpression(Expression selectorExpression)

Configure a SpEL expression to select messages. The root object for the expression evaluation is a MimeMessage which should return a boolean result (true means select the message).

Parameters:

selectorExpression - the selectorExpression.

Returns:

the spec.

selector

public S selector(Function<MimeMessage,Boolean> selectorFunction)

Configure a Function to select messages. The argument for the function is a MimeMessage; apply returns a boolean result (true means select the message).

Parameters:

selectorFunction - the selectorFunction.

Returns:

the spec.

• FunctionExpression

session

public S session(Session session)

Provide the Java Mail Session to use.

Parameters:

session - the session.

Returns:

the spec.

See Also:

• AbstractMailReceiver.setSession(Session)

javaMailProperties

public S javaMailProperties(Properties javaMailProperties)

The Java Mail properties.

Parameters:

javaMailProperties - the javaMailProperties.

Returns:

the spec.

See Also:

• AbstractMailReceiver.setJavaMailProperties(Properties)

javaMailProperties

public S javaMailProperties(Consumer<PropertiesBuilder> configurer)

Configure the javaMailProperties by invoking a Consumer callback which is invoked with a PropertiesBuilder.

Parameters:

configurer - the configurer.

Returns:

the spec.

See Also:

• AbstractMailReceiver.setJavaMailProperties(Properties)

javaMailAuthenticator

public S javaMailAuthenticator(Authenticator javaMailAuthenticator)

The Java Mail Authenticator.

Parameters:

javaMailAuthenticator - the javaMailAuthenticator.

Returns:

the spec.

See Also:

• AbstractMailReceiver.setJavaMailAuthenticator(Authenticator)

maxFetchSize

public S maxFetchSize(int maxFetchSize)

The maximum for fetch size.

Parameters:

maxFetchSize - the maxFetchSize.

Returns:

the spec.

See Also:

• AbstractMailReceiver.setMaxFetchSize(int)

shouldDeleteMessages

public S shouldDeleteMessages(boolean shouldDeleteMessages)

A flag to specify if messages should be deleted after receive.

Parameters:

shouldDeleteMessages - the shouldDeleteMessages.

Returns:

the spec.

See Also:

• AbstractMailReceiver.setShouldDeleteMessages(boolean)

userFlag

public S userFlag(String userFlag)

Set the name of the flag to use to flag messages when the server does not support \Recent but supports user flags; default "spring-integration-mail-adapter".

Parameters:

userFlag - the flag.

Returns:

the spec.

See Also:

• AbstractMailReceiver.setUserFlag(String)

headerMapper

public S headerMapper(HeaderMapper<MimeMessage> headerMapper)

Set the header mapper; if a header mapper is not provided, the message payload is a MimeMessage, when provided, the headers are mapped and the payload is the MimeMessage content.

Parameters:

headerMapper - the header mapper.

Returns:

the spec.

See Also:

• AbstractMailReceiver.setUserFlag(String)
• embeddedPartsAsBytes(boolean)

embeddedPartsAsBytes

public S embeddedPartsAsBytes(boolean embeddedPartsAsBytes)

When a header mapper is provided determine whether an embedded Part (e.g Message or Multipart content is rendered as a byte[] in the payload. Otherwise, leave as a Part. These objects are not suitable for downstream serialization. Default: true.

This has no effect if there is no header mapper, in that case the payload is the MimeMessage.

Parameters:

embeddedPartsAsBytes - the embeddedPartsAsBytes to set.

Returns:

the spec.

See Also:

• headerMapper(HeaderMapper)

simpleContent

public S simpleContent(boolean simpleContent)

Determine how the content is rendered.

Parameters:

simpleContent - true for simple content.

Returns:

the spec.

See Also:

• AbstractMailReceiver.setSimpleContent(boolean)

autoCloseFolder

public S autoCloseFolder(boolean autoCloseFolder)

When configured to false, the folder is not closed automatically after a fetch. It is the target application's responsibility to close it using the IntegrationMessageHeaderAccessor.CLOSEABLE_RESOURCE header from the message produced by this channel adapter.

Parameters:

autoCloseFolder - set to false to keep folder opened.

Returns:

the spec.

Since:

5.2
