【JavaWeb项目】一个众筹网站的开发（九）邮件开发

Java官方支持邮件开发，Javax-mail

jdk中默认没有，需要另外下载

apache的基于Javax-mail开发了commons-mail，更加简单高效，推荐使用

一、电子邮件接收和发送协议

二、Apache-James邮件服务器

1.自己搭建

1）将压缩包解压到非中文无空格路径

2）解决jar包冲突

3）操作一些命令设置服务器

设置服务器的域名，给服务器设置用户名和密码

其实james服务器也是将所有数据存在数据库中，默认自带的

可以让james保存到mysql中

mysql驱动的jar放入conf的lib下 James安装目录下的lib是默认的jar，conf中的lib是自定义的jar

打开james-database-template.properties配置，并改名为james-database.properties
