SpelEvaluationException: EL1011E: (pos 0): вызов метода: попытка вызова метода isAnonymous () для нулевого объекта контекста

Question

Когда я изменил свою конфигурацию безопасности Spring для использования use-expressions="true" в разделе http, я начал получать org.springframework.expression.spel.SpelEvaluationException: EL1011E:(pos 0): Method call: Attempted to call method isAnonymous() on null context object

Ниже приведен мой новый конфигурационный файл безопасности, который выходит из строя с приведенным выше исключением

Раньше при использовании приведенной ниже конфигурации безопасности все работало нормально

Разница только между двумя настройками безопасности в разделе http.Я использую Spring Security версии 3.2.5

Если какие-либо детали необходимы, пожалуйста, дайте мне знать.Спасибо
