低效率的EhCache性能

递归版本完全正常

类org.hibernate.type.AbstractType

public int getHashCode(Object x) {   if (x instanceof Object[]){ int result = 1; for (Object element : (Object[]) x)     result = 31 * result + (element == null ? 0 : getHashCode(element)); return result;        }        return x.hashCode();    }

和

public static boolean arraysEquals(Object[] a, Object[] a2) { if (a==a2)     return true; if (a==null || a2==null)     return false; int length = a.length; if (a2.length != length)     return false; for (int i=0; i<length; i++) {     Object o1 = a[i];     Object o2 = a2[i];     if (o1==null){         if (o2!=null)          return false;     }else{         if (o2==null)  return false;         if (o1 instanceof Object[]){  if (!(o2 instanceof Object[]))      return false;  else      if (!arraysEquals( (Object[]) o1, (Object[]) o2))          return false;         }else  if (!o1.equals(o2))      return false;     }      } return true;    }    public static boolean equals(final Object x, final Object y) {        if (x!=null && x instanceof Object[] && y!=null && y instanceof Object[] ) return arraysEquals((Object[])x, (Object[])y);        return x == y || ( x != null && y != null && x.equals( y ) );    }
