客户给的邮件服务器要SSL,使用Spring的JavaMailSenderImpl,Spring配置如下
<bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="${mail.smtp.host}" />
<property name="username" value="${mail.smtp.username}" />
<property name="password" value="${mail.smtp.password}" />
<property name="port" value="${mail.smtp.port}" />
<property name="javaMailProperties">
<props>
<prop key="mail.smtp.timeout">${mail.smtp.timeout}</prop>
<prop key="mail.smtp.auth">${mail.smtp.auth}</prop>
<prop key="mail.smtp.starttls.enable">${mail.smtp.starttls.enable}</prop>
<prop key="mail.smtp.socketFactory.port">${mail.smtp.port}</prop>
<prop key="mail.smtp.socketFactory.class">javax.net.ssl.SSLSocketFactory</prop>
<prop key="mail.smtp.socketFactory.fallback">false</prop>
</props>
</property>
</bean>
mail.properties内容如下
mail.smtp.host=smtp.xyz.com
mail.smtp.port=465
mail.smtp.username=alerts+abc.net
mail.smtp.password=12345678
mail.smtp.auth=true
mail.smtp.starttls.enable=true
mail.smtp.timeout=50000
[email protected]
[email protected]
发送邮件时得到异常如下

Google一下,需要保存安装证书
官方的QA http://java.sun.com/products/javamail/FAQ.html#installcert
Q: When connecting to my mail server over SSL I get an exception like "unable to find valid certification path to requested target".
A: Your server is probably using a test certificate or self-signed certificate instead of a certificate signed by a commercial Certificate Authority. You'll need to install the server's certificate into your trust store. The InstallCert program will help.
在这里 http://blogs.sun.com/andreas/entry/no_more_unable_to_find 有解决方案
用 http://blogs.sun.com/andreas/resource/InstallCert.java 的代码来安装证书
运行 java InstallCert smtp.xyz.com:465
得到jssecacerts文件后复制到jdk1.6.0_14\jre\lib\security目录
然后再发送邮件就OK了
附件是 InstallCert.java
