Check online beginning this error message, the adoption of such a statement: There is not a legitimate symbol,
resulting in xml parsing unsuccessful. So copied from other xml file can be run through in a number == found
really successful operation, when time is running out, there are other tasks at hand, careful to verify there is no more than
a few times, if verified more than a few times, it will find practical problems still exist (that I still have yet
to understand why the beginning can run successfully), then I will try "oR" change "or" change and
will "||", not found problem, initially determined that the cause mybatis does not recognize the uppercase OR. AND not be capitalized
