I want to display the info about the user logged in like his details etc given during sign up ...how to do it ?? As iam new to grails plz help! iam using Spring security plugin

推荐答案

您可以使用springSecurityService来获取控制器中的一些用户信息： b
$ b

Well you can use the springSecurityService to get some user information in a controller:

    class MyController {
      def springSecurityService

      def myAction() {
        def principal = springSecurityService.principal
        String username = principal.username
        ...
      }
     }

或在gsp中

    <sec:loggedInUserInfo field="username" />

这是一个相当普遍的问题。

It is a pretty general question.
