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("qinjiangli0003@163.com");         mail.setFrom("qinjiangli0003@163.com");         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("qinjiangli0003@163.com");                      messagehelper.setFrom("qinjiangli0003@163.com");                      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
