我有问题。我的代码在我的localhost机器上运行良好。但是当我在服务器上部署.war时它无法发送电子邮件。我不知道为什么。 服务器位于同一网络中并成功ping通。 mserv3.int.pan.wroc.pl所以这不是DNS的问题。
我的本地开发机器：Ubuntu 14.04 + Tomcat 7 服务器：CentOS 6 + Tomcat 7
答案 0 :(得分：1)
stacktrace告诉你问题的原因：
引起：javax.mail.MessagingException：无法获取本地主机名。请正确配置JDK / DNS或设置mail.smtp.localhost
看起来好像JavaMail无法确定它运行的主机的名称。尝试异常中的建议。
以下声明的结果是什么？
bash> cat /etc/hostname
如果无法通过DNS设置主机名或获取名称，请尝试使用属性mail.smtp.localhost。
Here是失败方法的源代码。也许被调用的#getHostName()-method的JavaDoc很有帮助：
获取此IP地址的完全限定域名。尽力而为方法，这意味着我们可能无法返回FQDN，具体取决于底层系统配置。
如果有安全管理器，则此方法首先使用hostname和-1作为其参数调用其checkConnect方法，以查看是否允许调用代码知道此IP地址的主机名，即连接到主机。如果不允许该操作，它将返回IP地址的文本表示。
答案 1 :(得分：0)
我的服务器主机名
bash> hostname
vm10.int.pan.wroc.pl
我补充说：
props.put（＆＃34; mail.smtp.localhost＆＃34;，＆＃34; vm10.int.pan.wroc.pl＆＃34;）;
现在它可以工作，但我不明白为什么。我必须分享我的.war。人们不应该在使用CentOS 6的每台机器上编辑它。
