setProtocol
-
setSession
Set theSession
. Otherwise, the Session will be created by invocation ofSession.getInstance(Properties)
orSession.getInstance(Properties, Authenticator)
.- Parameters:
session
- The session.- See Also:
-
setJavaMailProperties
A newSession
will be created with these properties (and the JavaMailAuthenticator if provided). Use either this method orsetSession(jakarta.mail.Session)
, but not both.- Parameters:
javaMailProperties
- The javamail properties.- See Also:
-
getJavaMailProperties
-
setJavaMailAuthenticator
Optional, sets the Authenticator to be used to obtain a session. This will not be used ifsetSession(jakarta.mail.Session)
has been used to configure theSession
directly.- Parameters:
javaMailAuthenticator
- The javamail authenticator.- See Also:
-
setMaxFetchSize
public void setMaxFetchSize(int maxFetchSize) Specify the maximum number of Messages to fetch per call toreceive()
.- Parameters:
maxFetchSize
- The max fetch size.
-
setShouldDeleteMessages
public void setShouldDeleteMessages(boolean shouldDeleteMessages) Specify whether mail messages should be deleted after retrieval.- Parameters:
shouldDeleteMessages
- true to delete messages.
-
shouldDeleteMessages
protected boolean shouldDeleteMessages()Indicates whether the mail messages should be deleted after being received.- Returns:
- true when messages will be deleted.
-
getUserFlag
-
setUserFlag
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.- Since:
- 4.2.2
-
setHeaderMapper
Set the header mapper; if a header mapper is not provided, the message payload is aMimeMessage
, when provided, the headers are mapped and the payload is theMimeMessage
content.- Parameters:
headerMapper
- the header mapper.- Since:
- 4.3
- See Also:
-
setEmbeddedPartsAsBytes
public void setEmbeddedPartsAsBytes(boolean embeddedPartsAsBytes) When a header mapper is provided determine whether an embeddedPart
(e.gMessage
orMultipart
content is rendered as a byte[] in the payload. Otherwise, leave as aPart
. 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.- Since:
- 4.3
- See Also:
-
setSimpleContent
public void setSimpleContent(boolean simpleContent) MimeMessage.getContent()
returns just the email body.foo
Some subclasses, such asIMAPMessage
return some headers with the body.To: foo@bar From: bar@baz Subject: Test Email foo
Starting with version 5.0, messages emitted by mail receivers will render the content in the same way as theMimeMessage
implementation returned by javamail. In versions 2.2 through 4.3, the content was always just the body, regardless of the underlying message type (unless a header mapper was provided, in which case the payload was rendered by the underlyingMimeMessage
.To revert to the previous behavior, set this flag to true. In addition, even if a header mapper is provided, the payload will just be the email body.
- Parameters:
simpleContent
- true to render simple content.- Since:
- 5.0
-
setAutoCloseFolder
public void setAutoCloseFolder(boolean autoCloseFolder) Configure aboolean
flag to close the folder automatically after a fetch (default) or populate an additionalIntegrationMessageHeaderAccessor.CLOSEABLE_RESOURCE
message header instead. It is the downstream flow's responsibility to obtain this header and call itsclose()
whenever it is necessary.Keeping the folder open is useful in cases where communication with the server is needed when parsing multipart content of the email with attachments.
The
setSimpleContent(boolean)
andsetHeaderMapper(HeaderMapper)
options are not affected by this flag.- Parameters:
autoCloseFolder
-false
do not close the folder automatically after a fetch.- Since:
- 5.2
-
getFolder
-
getFolderOpenMode
protected int getFolderOpenMode() -
