Spring中发送邮件

 

在使用spring的邮件反送的时候，个人理解是先要有一个邮件发送器可以使用任意一个smtp进行邮件发送，使用此功能必须使用的jar文件为

spring-context.jar
  mail.jar
  spring-core.jar
  activation.jar
  commons-logging.jar

在resin和weblogic下启动均无异常发生但在tomcat下发生如下异常

java.lang.NoClassDefFoundError:javax/mail/MessagingException

这个问题的解决方法为将mail.jar和activation.jar放入tomcat下的lib下

Spring  bean的编写：

<bean id="mailSender"

        class="org.springframework.mail.javamail.JavaMailSenderImpl"

        abstract="false" singleton="true" lazy-init="default"

        autowire="default" dependency-check="default" >

        <property name="host">

            <value>smtp.126.com</value>

        </property>

        <property name="javaMailProperties">

            <props>

                <prop key="mail.smtp.auth">true</prop>

                <prop key="mail.smtp.timeout">25000</prop>

            </props>

        </property>

        <property name="username">

            <value>username</value>

        </property>

        <property name="password">

            <value>********</value>

        </property>

    </bean>

但在后台进行注入后总是发生如下异常

错误原因查明为使用发送邮件的信箱为刚刚注册的126信箱，不提供使用此功能所以更换其他邮箱以后问题解决

必须注意的是你发送邮件的时候使用的from邮箱必须是XML文件中配置的邮箱否则会发生异常
简单文本邮件发送

SimpleMailMessage mail = new SimpleMailMessage();

        mail.setTo("[email protected]");

        mail.setFrom("[email protected]");

        mail.setSubject("这里是标题");

        mail.setText("这是里内容");

        //JavaMailSender sender = (JavaMailSender)Mailsender;

        mailSender.send(mail);

发送超文本格式的邮件（带附件）

MimeMessage mailmessage  = mailSender.createMimeMessage();

               try {

                     MimeMessageHelper messagehelper = new MimeMessageHelper(mailmessage,true);

                     messagehelper.setTo("[email protected]");

                     messagehelper.setFrom("[email protected]");

                     messagehelper.setSubject("图片附件邮件标题");

                     String text="<html><body><a href=/"http://www.maishebei.com/" target=/"_blank/"><img src=/"cid:logo/"/></a>";

                     text+="<br><a href=/"http://www.maishebei.com/" target=/"_blank/"><font size=/"3/">中国机床设备团够网</font></a>";

                     text+="<br>尊敬的*****用户您在机床设备团购网的新密码为：<br>********请及时更换你的密码";

                     text+="</body></html>";

                     //messagehelper.sett

                      

                     messagehelper.setText(text,true);

                     String basepath=this.getServlet().getServletContext().getRealPath("/");

                    

                     FileSystemResource img = new FileSystemResource(new File(basepath+"mainimg//logo1.gif"));

                  messagehelper.addInline("logo", img);

                  FileSystemResource file = new FileSystemResource(new File(basepath+"mainimg//gg.jpg"));

                  messagehelper.addAttachment("gg.jpg", file);

                  mailSender.send(mailmessage);

               } catch (MessagingException e) {

                     // TODO 自动生成 catch 块

                     e.printStackTrace();

              }

但是发送出现以下问题 即使在不转码的时候也一样出现这个乱码问题

 

MimeMessageHelper(mailmessage,true);

该为MimeMessageHelper(mailmessage,true,”gb2312”);后正常显示
