MyBatis Error: MySQLSyntaxErrorException - "You have an error in your SQL syntax" 解决方法

This exception is thrown when there is an error updating the database using MyBatis. The specific error is a MySQLSyntaxErrorException, indicating that there is a syntax error in the SQL statement being executed.\n\nIn this case, the error message suggests that there is a syntax error near the expression "=!{item.id} \u4ec0\u4e48\u610f\u601d". It appears that there is a typo in the SQL statement where it is trying to use the "!" operator instead of the "!=" operator, which is the correct syntax for "not equal to" in SQL.\n\nTo fix this issue, you should correct the syntax error in your SQL statement and ensure that it is valid for the MySQL version you are using.
