spring mvc javamail配置

1.Spring的集成功能 

    在Spring的spring-context-support-3.2.4.RELASE.jar包中提供了Spring對cache,mail, schedule,ui的集成。

    Spring對JavaMail的支持的類在：org.springframework.mail和org.springframework.mail.javamail包中。

 

  2.Spring對JavaMail集成的實現

     主要有兩個接口和接口的實現類

    接口：org.springframework.mail.MailMessage

    實現類：org.springframework.mail.SimpleMailMessage

    接口：org.springframework.mail.javamail.JavaMailSender

    實現類：org.springframework.mail.javamail.JavaMailSender.JavaMailSenderImpl
