MimeMessageItemWriter (Spring Batch 4.1.4.RELEASE API)

java.lang.Object
- org.springframework.batch.item.mail.javamail.MimeMessageItemWriter

所有已实现的接口:
ItemWriter<javax.mail.internet.MimeMessage>
```
public class MimeMessageItemWriter
extends java.lang.Object
implements ItemWriter<javax.mail.internet.MimeMessage>
```
A simple ItemWriter that can send mail messages. If it fails there is no guarantee about which of the messages were sent, but the ones that failed can be picked up in the error handler. Because the mail protocol is not transactional, failures should be dealt with here if possible rather than allowing them to be rethrown (which is the default).
Delegates the actual sending of messages to a JavaMailSender, using the batch method JavaMailSender.send(MimeMessage[]), which normally uses a single server connection for the whole batch (depending on the implementation). The efficiency of for large volumes of messages (repeated calls to the item writer) might be improved by the use of a special JavaMailSender that caches connections to the server in between calls.
Stateless, so automatically restartable.
