使用spring发送邮件例

做了个spring发送纯文本文件以及发送带附件的邮件的例子，共享之。
说明：把spring-framework-3.0.0.M4的所以包加进去，还要加
commons-logging-1.0.4.jar不然会报：java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory
还要加入j2ee1.4的包，如果加入高一点的包可能还是会报错，报找不到smtp的错，这是包不一致造成的。

这是配置文件applicationContext-beans.xml

其中的

sun.misc.BASE64Encoder enc = new sun.misc.BASE64Encoder();
attachFile.setFileName("=?utf-8?B?"+enc.encode(fds.getName().getBytes())+"?=");
是为了解决中文的问题
