Question

i have a problem is shown below;

groovy.lang.MissingMethodException: No signature of method:
    static org.springframework.security.oauth.User.withTransaction() is applicable for argument types:
    (org.springframework.security.oauth.services.UserService$_saveUser_closure1) values:
    [org.springframework.security.oauth.services.UserService$_saveUser_closure1@2ed1e8 at 
    groovy.lang.MetaClassImpl.invokeStaticMissingMethod(MetaClassImpl.java:1357)

UserService:

class UserService {

  public boolean saveUser(){
    boolean retVal=false;
    User.withTransaction{status ->
      def sUser = new User()
      sUser.setUsername("muhammed")
      sUser.save()
      retVal= true
    }
    return retVal;
  }
}

User.groovy:

@Entity
class User {
  String id;
  String username;
  String password;//social agent id

  static constraints = {
    username(nullable:true)
    password(nullable:true)
  }
  static mapping  = {
    id generator: 'uuid'
  }
}

what is the problem i cant find?

Answer 1

I believe you imported the wrong User class in your service. Most likely you have something like

import org.springframework.security.oauth.User

on top of your UserService.groovy file, whereas you need to import your domain class.
