Class JavaMailSenderImpl

java.lang.Object
  org.springframework.mail.javamail.JavaMailSenderImpl

All Implemented Interfaces:

JavaMailSender, MailSender

public class JavaMailSenderImpl
extends Object
implements JavaMailSender

Production implementation of the 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.

Constructor Detail

JavaMailSenderImpl

public JavaMailSenderImpl()

Create a new instance of the JavaMailSenderImpl class.

Initializes the "defaultFileTypeMap" property with a default ConfigurableMimeFileTypeMap.

Method Detail

setJavaMailProperties

public void setJavaMailProperties(Properties javaMailProperties)

Set JavaMail properties for the Session.

A new Session will be created with those properties. Use either this method or setSession(javax.mail.Session), but not both.

Non-default properties in this instance will override given JavaMail properties.

setSession

public void setSession(Session session)

Set the JavaMail Session, 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 the Session.

See Also:

setJavaMailProperties(java.util.Properties)

getSession

public Session getSession()

Return the JavaMail Session.

setProtocol

public void setProtocol(String protocol)

Set the mail protocol. Default is "smtp".

getProtocol

public String getProtocol()

Return the mail protocol.

setHost

public void setHost(String host)

Set the mail server host, typically an SMTP host.

Default is the default host of the underlying JavaMail Session.

getHost

public String 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

public void setUsername(String username)

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 to true, else the specified username will not be sent to the mail server by the JavaMail runtime. If you are not explicitly passing in a Session to use, simply specify this setting via setJavaMailProperties(java.util.Properties).

See Also:

setSession(javax.mail.Session), setPassword(java.lang.String)

getUsername

public String getUsername()

Return the username for the account at the mail host.

setPassword

public void setPassword(String password)

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 to true, else the specified password will not be sent to the mail server by the JavaMail runtime. If you are not explicitly passing in a Session to use, simply specify this setting via setJavaMailProperties(java.util.Properties).

See Also:

setSession(javax.mail.Session), setUsername(java.lang.String)

getPassword

public String getPassword()

Return the password for the account at the mail host.

setDefaultEncoding

public void setDefaultEncoding(String defaultEncoding)

Set the default encoding to use for MimeMessages created by this instance.

Such an encoding will be auto-detected by MimeMessageHelper.

getDefaultEncoding

public String getDefaultEncoding()

Return the default encoding for MimeMessages, or null if none.

setDefaultFileTypeMap

public void setDefaultFileTypeMap(FileTypeMap defaultFileTypeMap)

Set the default Java Activation FileTypeMap to use for MimeMessages created by this instance.

A FileTypeMap specified here will be autodetected by MimeMessageHelper, avoiding the need to specify the FileTypeMap for each MimeMessageHelper instance.

For example, you can specify a custom instance of Spring's ConfigurableMimeFileTypeMap here. If not explicitly specified, a default ConfigurableMimeFileTypeMap will be used, containing an extended set of MIME type mappings (as defined by the mime.types file contained in the Spring jar).

See Also:

MimeMessageHelper.setFileTypeMap(javax.activation.FileTypeMap)

getDefaultFileTypeMap

public FileTypeMap getDefaultFileTypeMap()

Return the default Java Activation FileTypeMap for MimeMessages, or null if none.
