java.lang.IllegalArgumentException:   id   to   load   is   required   for   loading
出现这种错误是因为SQL查询时,传入的参数（以？形式）为空
最好debug或者System.out.println()下,看看哪个字段是null!
java.lang.IllegalArgumentException: id to load is required for loading
我要遇到了应该是id 不能为NULL
非常同意很明显啰，SQL没有给id赋值！你肯定是getInformationById(..)...
出现该错误可能是运用hibernate的getSession().get(Example.class,id),而传给该方法的id参数为null,会报id to load is required for loading错误
