mybatis报错：org.apache.ibatis.ognl.ParseException: Encountered “” at line 1, column 0.

具体报错代码如下：

org.apache.ibatis.ognl.ParseException: Encountered "<EOF>" at line 1, column 0.
Was expecting one of:
    ":" ...
    "not" ...
    "+" ...
    "-" ...
    "~" ...
    "!" ...
    "(" ...
    "true" ...
    "false" ...
    "null" ...
    "#this" ...
    "#root" ...
    "#" ...
    "[" ...
    "{" ...
    "@" ...
    "new" ...
    <IDENT> ...
    <DYNAMIC_SUBSCRIPT> ...
    "\'" ...
    "`" ...
    "\"" ...
    <INT_LITERAL> ...
    <FLT_LITERAL> ...

报错原因：在mybatis的xml文件的SQL语句中出现了问题，如使用了大写字符“OR”，“AND”等，或者语法错误（可以在数据库中测试成功后再放入xml文件中），如动态SQL的标签使用错误等。
