out我认为这是对在
布局中使用此类标记的限制，因为它是在提交hibernate会话后由SiteMesh处理的

解决方案是将其包装在一个会话中（
withNewSession
域类的关闭）。类似于：

LayoutTagLib是一个TagLib，您可以使用命令create TagLib创建


grails create-tag-lib com.app.layout.LayoutTagLib


重要提示：用应用程序的任何现有域类替换“SomeDomain”


class LayoutTagLib {
  static namespace = "my"

  def header = { attrs ->
    SomeDomain.withNewSession {
      sec.ifLoggedIn() {
        out << "Logged In"
      }
    }
  }
}


编辑：

您需要使用newsession将查询包装在
中，并从标题中删除内容，只需调用taglib即可。要获取用户数据，可以使用
springSecurityService


package com.mycompany.myapp.layout
import  com.mycompany.myapp.trips.Trip

class LayoutTagLib {
    //dependency injection of the plugin service
    def springSecurityService

    static namespace = "my"

      def header = { attrs ->

        Trip.withNewSession {

          sec.ifLoggedIn() {

            def userId = springSecurityService.currentUser.id
            def userDetails = SystemUserRole.get(userId)

            //better transform this in a private method or a template!
            out << """<div class="mast_head">
              <ul>
                <li>Welcome ${userDetails?.party?.firstName}</li>
                <li> | </li>
                <li><a href="${createLink(controller: "systemUserRole", action: "editprofile")}">Profile</a></li>
                <li> | </li>
                <li><a href="${createLink(controller: "systemUserRole", action: "changepassword")}">Edit Password</a></li>
                <li> | </li>
                <li><a href="${createLink(controller: "logout", action: "index")}">Sign Out</a></li>
              </ul>
            </div>"""              
           }
         }
      }
}



package com.mycompany.myapp.layout

//插件服务的依赖注入
def springSecurityService

//最好在私有方法或模板中进行转换！

我需要用每个域类包装吗？不，只有一个。闭包对所有域类都是一样的。请解释一下。我需要把代码放在哪里。我是grails的新手…非常感谢逐步回答。-谢谢。我更新了问题。如果我替换掉（thml，它将打印在页面中），它会给出错误。。
