动态Grails Url映射配置

Question

如何动态构建映射列表 - 而不是:

class UrlMappings {
static mappings = {
   "/helpdesk/user/$action?/$id?" (controller="helpdeskuser")
   "/helpdesk/group/$action?/$id?" (controller="helpdeskgroup")
   "/helpdesk/company/$action?/$id?" (controller="helpdeskcompany")
   "/helpdesk/account/$action?/$id?" (controller="helpdeskaccount")
   "/admin/company/$action?/$id?" (controller="admincompany")
   "/admin/account/$action?/$id?" (controller="adminaccount")
 }
}

像这样的伪代码:

class UrlMappings {
static mappings = {
   application.controllerClasses.each {
     if(it.name.startsWith('helpdesk'))
        "/helpdesk/${it.name}/$action?/$id?" (controller="${it.name}")
     if(it.name.startsWith('admin'))
        "/admin/${it.name}/$action?/$id?" (controller="${it.name}")
   }
 }
}

(我不明白静态映射是什么 - 哈希映射？自由变量？)

我想要实现的是基于控制器类型的映射 - 例如帮助台,管理员或用户控制器.一旦我设置了映射,我想基于URL添加安全性,但我不想单独映射每个控制器:

grails.plugins.springsecurity.interceptUrlMap = [
   '/helpdesk/**':   ['ROLE_HELPDESK','ROLE_ADMIN'],
]

我刚刚在我的应用程序中完成了以下操作:

import org.codehaus.groovy.grails.commons.ApplicationHolder

class UrlMappings {
  static mappings = {        
    for( controllerClass in ApplicationHolder.application.controllerClasses) {
      // Admin Controllers first
      if( controllerClass.name.startsWith("Admin")){
        // note... fixes the case so that AdminUserController maps to /admin/user
        "/admin/${controllerClass.name[5].toLowerCase() + controllerClass.name[6..-1]}/$action?/$id?" {
          controller = "admin${controllerClass.name[5..-1]}".toString()
        }
      }
    }
  }
}

我之前没有真正做到这一点,你的问题促使我解决这个问题.这是我一直尝试做的事情之一.

grailsUrlMappingsHolder bean在服务和控制器中可用.虽然UrlMappingsHolder的具体实现没有add方法,但是它的超类确实如此.这简单如grails 2.3.4

def grailsUrlMappingsHolder

def addMapping() {        
    grailsUrlMappingsHolder.addMappings({
        "/admin"(controller:"admin" action:"index")  
    });        
}
