Class JavaMailSenderImpl
- All Implemented Interfaces:
JavaMailSender
,MailSender
JavaMailSender
interface,
supporting both JavaMail MimeMessages
and Spring
SimpleMailMessages
. Can also be used as a
plain MailSender
implementation.
Allows for defining all settings locally as bean properties.
Alternatively, a pre-configured JavaMail Session
can be
specified, possibly pulled from an application server's JNDI environment.
Non-default properties in this object will always override the settings
in the JavaMail Session
. Note that if overriding all values locally,
there is no added value in setting a pre-configured Session
.

JavaMailSenderImpl
public JavaMailSenderImpl()Create a new instance of theJavaMailSenderImpl
class.Initializes the
"defaultFileTypeMap"
property with a defaultConfigurableMimeFileTypeMap
.

-
Method Details
-
setJavaMailProperties
Set JavaMail properties for theSession
.A new
Session
will be created with those properties. Use either this method orsetSession(jakarta.mail.Session)
, but not both.Non-default properties in this instance will override given JavaMail properties.
-
getJavaMailProperties
Allow {code Map} access to the JavaMail properties of this sender, with the option to add or override specific entries.Useful for specifying entries directly, for example via {code javaMailProperties[mail.smtp.auth]}.
-
setSession
Set the JavaMailSession
, possibly pulled from JNDI.Default is a new
Session
without defaults, that is completely configured via this instance's properties.If using a pre-configured
Session
, non-default properties in this instance will override the settings in theSession
. -
getSession
Return the JavaMailSession
, lazily initializing it if it hasn't been specified explicitly. -
setProtocol
Set the mail protocol. Default is "smtp". -
getProtocol
Return the mail protocol. -
setHost
Set the mail server host, typically an SMTP host.Default is the default host of the underlying JavaMail Session.
-
getHost
Return the mail server host. -
setPort
public void setPort(int port) Set the mail server port.Default is
DEFAULT_PORT
, letting JavaMail use the default SMTP port (25). -
getPort
public int getPort()Return the mail server port. -
setUsername
Set the username for the account at the mail host, if any.Note that the underlying JavaMail
Session
has to be configured with the property"mail.smtp.auth"
set totrue
, else the specified username will not be sent to the mail server by the JavaMail runtime. If you are not explicitly passing in aSession
to use, simply specify this setting viasetJavaMailProperties(java.util.Properties)
. -
getUsername
Return the username for the account at the mail host. -
setPassword
Set the password for the account at the mail host, if any.Note that the underlying JavaMail
Session
has to be configured with the property"mail.smtp.auth"
set totrue
, else the specified password will not be sent to the mail server by the JavaMail runtime. If you are not explicitly passing in aSession
to use, simply specify this setting viasetJavaMailProperties(java.util.Properties)
. -
getPassword
Return the password for the account at the mail host. -
setDefaultEncoding
Set the default encoding to use forMimeMessages
created by this instance.Such an encoding will be auto-detected by
MimeMessageHelper
. -
getDefaultEncoding
Return the default encoding forMimeMessages
, ornull
if none. -
setDefaultFileTypeMap
Set the default Java ActivationFileTypeMap
to use forMimeMessages
created by this instance.A
FileTypeMap
specified here will be autodetected byMimeMessageHelper
, avoiding the need to specify theFileTypeMap
for eachMimeMessageHelper
instance.For example, you can specify a custom instance of Spring's
ConfigurableMimeFileTypeMap
here. If not explicitly specified, a defaultConfigurableMimeFileTypeMap
will be used, containing an extended set of MIME type mappings (as defined by themime.types
file contained in the Spring jar). -
