为了让用户信息更贴近实际需求，修改如下信息：
1、让登录名可以使用数字、“.”、“_”等
在/portal-master/portal-impl/src/portal.properties文件中，有如下配置：
#
# Set this to true when you want the validation to allow for creation of
# numeric screen names.
#
users.screen.name.allow.numeric=false
#
# Input a class name that implements
# com.liferay.portal.security.auth.ScreenNameValidator. This class will be
# called to validate user screen names.
#
users.screen.name.validator=com.liferay.portal.security.auth.DefaultScreenNameValidator
#users.screen.name.validator=com.liferay.portal.security.auth.LiberalScreenNameValidator
修改为：
#
# Set this to true when you want the validation to allow for creation of
# numeric screen names.
#
users.screen.name.allow.numeric=true
#
# Input a class name that implements
# com.liferay.portal.security.auth.ScreenNameValidator. This class will be
# called to validate user screen names.
#
#users.screen.name.validator=com.liferay.portal.security.auth.DefaultScreenNameValidator
users.screen.name.validator=com.liferay.portal.security.auth.LiberalScreenNameValidator
2、用户信息中邮件设置为不必填
在/portal-master/portal-impl/src/portal.properties文件中，有如下配置：
#
# Set this to false if you want to be able to create users without an email
# address. An email address will be automatically assigned to a user based
# on the property "users.email.address.auto.suffix".
#
users.email.address.required=true
修改为：
#
# Set this to false if you want to be able to create users without an email
# address. An email address will be automatically assigned to a user based
# on the property "users.email.address.auto.suffix".
#
users.email.address.required=false
