如何在Liferay主题中获取登录用户的角色？如何检查用户是否属于某个特定角色？

Answer 1

UserLocalService有hasRoleUser方法，可用于查明用户是否属于某个特定角色。下面的代码可以放在navigation.vm文件夹下的templates文件中。

#set($UserLocalServiceUtil = $serviceLocator.findService("com.liferay.portal.service.UserLocalService"))
#if ($UserLocalServiceUtil.hasRoleUser(roleID, $user.getUserId())) // It takes roleID as input to check.
  //Proceed with whatever you want to 
#else
  //Proceed with something else

注意：如果您使用com.liferay.portal.service.UserLocalService，而不是com.liferay.portal.service.UserLocalServiceUtil，正如在this等资源中可能会发现的那样，您将遇到以下异常，

ERROR com.liferay.portal.kernel.bean.BeanLocatorException: org.springframework.beans.factory.NoSuchBeanDefinitionException: No
  bean named 'com.liferay.portal.service.UserLocalServiceUtil' is defined
  com.liferay.portal.kernel.bean.BeanLocatorException: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'com.liferay.portal.servi
ce.UserLocalServiceUtil' is defined

另一种方式是，

#set($role=$serviceLocator.findService("com.liferay.portal.service.RoleLocalService"))
$role.getUserRoles($user_id)

Answer 2

只需遍历init.vm中定义的$ user对象

#set ($user_roles = $user.getRoles())
#foreach($role in $user_roles)
   $role.name<br />
#end
