如何在grails shiro中使用缓存权限 [英] how to use cache permissions in grails shiro

问题描述

每次我调用subject.isPermitted（）时，它都会向数据库发送一个sql。
如何缓存它？

任何示例？谢谢

---

我读过了shiro grails插件的文档。但不能解决它。

数据源：

  hibernate {
 cache.use_second_level_cache = true 
 cache.use_query_cache = true 
 cache.provider_class ='net.sf.ehcache.hibernate.EhCacheProvider'
} 
  

那么如何将cachemanager设置为shiro？我尝试spring.resource，抛出一个错误。

以及cachemanager的实例bean名称是什么？我需要配置其他的？

解决方案

您需要配置一个org.apache.shiro.cache.CacheManager实例在Shiro的SecurityManager上。 Shiro的大部分开箱即用Realm实现知道如何使用配置的CacheManager，并自动缓存从Realm权限查询返回的AuthorizationInfo。

我是不知道如何使用Grails Shiro插件来做到这一点，但在Shiro的INI中，您可以这样做：

  [main ] 
 ... 
 cacheManager = com.my.implementation.of.CacheManager 
 securityManager.cacheManager = $ cacheManager 
 ... 
  

我建议您问一下grails-user邮件列表，看看Grails Shiro插件是否有更多'grailsy'的配置方式。

HTH，

everytime i call subject.isPermitted(), it send a sql to db. how can i cache it?

any example? thanks

i had read the doc of shiro grails plugin. but cant solove it.

DataSource:

hibernate {
    cache.use_second_level_cache = true
    cache.use_query_cache = true
    cache.provider_class = 'net.sf.ehcache.hibernate.EhCacheProvider'
}

then how to set the cachemanager to shiro? i try spring.resource,throw an error.

and what's the instance bean name of cachemanager? do i need to config sth else?

解决方案

You'll need to configure an org.apache.shiro.cache.CacheManager instance on Shiro's SecurityManager. Most of Shiro's out-of-the-box Realm implementations know how to work with a configured CacheManager and will cache AuthorizationInfo returned from a Realm permission lookup automatically.

I'm not sure how to do this using the Grails Shiro plugin, but in Shiro's INI, you would do that this way:

[main]
...
cacheManager = com.my.implementation.of.CacheManager
securityManager.cacheManager = $cacheManager
...

I'd recommend asking the grails-user mailing list to see if there is a more 'grailsy' way to configure this for the Grails Shiro plugin.

HTH,
