public class MailTest {
     public static void main( String[] args )
        {

            MailMail mm = (MailMail) context.getBean("mailMail");
            //发送时候写好主题和内容
            mm.sendMail("Yiibai", "This is text content");

        }
}

非常简单。注意Spring-Mail.xml里面需要配置的地方。还有可能出现包冲突异常：

此异常咱没有解决，所以新搞了个项目，实现本例。
