从一台服务器的 Crowd 导出 XML，再在另一台服务器上导入，出现了一下异常：

原因在于导出的 XML 中存有与服务器有关的信息，XML 中重点信息如下：
<application> <id>2</id> <name>crowd</name> <createdDate>2016-03-31T22:42:33Z</createdDate> <updatedDate>2016-03-31T22:42:36Z</updatedDate> <active>true</active> <type>CROWD</type> <description>Crowd console</description> <remoteAddresses> <remoteAddress>10.47.217.53</remoteAddress> <remoteAddress>127.0.0.1</remoteAddress> <remoteAddress>iZ2586u0bguZ</remoteAddress> <remoteAddress>localhost</remoteAddress> </remoteAddresses>
从 XML 中可以看到 remoteAddresses 中有跟服务有关的 IP 和计算机名，这两个跟我们要导入的另一台服务器是不相符的。把这两条删掉就可以正常导入了。
另外，如果数据库是 mysql 或 mariadb 的话，还需要设置事务类型，在配置中加入以下设置：
[mysqld] transaction-isolation = READ-COMMITTED
