confluence7.4.6邮件配置

在使用confluence时，准备配置个邮件提醒，如果文章有变化能够比较方便的提醒用户，一开始不是很熟悉JNDI是如何配置的，为了方便直接通过简单的图形界面方式配置的邮件服务器。

1.邮件服务器配置

首先是填写SMTP服务器相关的配置项，具体配置如下图所示：

完了以后再填写邮件服务器信息，配置如下所示：

测试邮件发送

配置好邮件服务器后，发送测试邮件时，一直报发送超时的错误，直接上问题日志吧，

也在百度上找了一圈答案，大部分都是让换端口或者默认端口，基本上没有解决我的问题，后面我打算换成jndi的方式试试运气，步骤如下所示：

第一步：将WEB-INF/lib/邮件发送相关的jar包移到confluence下的lib目录下

关闭confluence服务
/etc/ini.d/confluence stop
迁移jar包,我的安装目录是默认目录：
/opt/atlassian/confluence/confluence/WEB-INF/lib/
所以我需要把这个目录的两个jar包javax.mail-api-1.6.2.jar javax.mail-1.6.2.jar移动到/opt/atlassian/confluence/lib下

第二步:修改server.xml配置文件

在前添加邮件发送配置信息

mail.debug="true"是为了查看发送邮件的调试信息
然后启动服务
/etc/ini.d/confluence start
然后再回到页面配置jndi

测试时再次报错，说是找不到mail，发现实Resource配置的位置不对，应该放在第一个前面，我放到第二个
修改后再次启动服务，还是报错，提示找不到
Caused by: java.lang.NoClassDefFoundError: javax/activation/DataSource
以前有配置过jira的邮件服务器，于是大概猜测是少了jar包
于是下载activation-1.1.1.jar到/opt/atlassian/confluence/lib目录下
将这个jar包的拥有者设置成confluence，执行
chown confluence:confluence activation-1.1.1.jar
再次启动confluence，测试邮件发送成功了
真可谓是一波三折，总算是解决了。
