И это действие URL, которые генерируют Excel Report

  xyz.action? 
      paramBean.st=02-07-2012+00%3A00 
      &paramBean.type=0 
      &paramBean.et=04-07-2012+00%3A00 
      &paramBean.did=294 
      &6578706f7274=1 
      &didSearch=Rishin-Scorpio 
      &paramBean.ust=1341167400 
      &d-49216-e=2 
      &go=GO 
      &paramBean.uet=1341340259 

По мне проблема может быть в URL 6578706f7274, отображающих как объект в OGNL. Пожалуйста, дайте мне знать, что это неправильно

Answer 1

На самом деле, я подозреваю, что ваш фактический запрос URL действительно содержит

&6578706f7274=[Ljava.lang.String;@1afb661 

... так же, как сообщение об исключении говорит.

Вы получите что-то подобное, если попытаетесь преобразовать объект String[] в строку, вызвав на нем Object.toString(). Посмотрите на код, в котором вы создаете запрос, и убедитесь, что вы используете правильный тип объекта для предоставления значения этого параметра запроса.
