SQL session [@4529 91]

The console log is as follows

DEBUG - Creating a new SqlSession
DEBUG - SqlSession [@4529fa91] was not registered for synchronization because synchronization is not active
DEBUG - Closing non transactional SqlSession [@4529fa91]

I didn't see the cause of the error. It can be concluded that it was from the SQL statement, and then add try catch to the SQL statement to view it.

try {
    (".addSheet2", body);
} catch (Exception e) {
    ();
}

Check the exception as follows

: nested exception is : Error evaluating expression 'createDate != null''. Cause: : Malformed OGNL expression: createDate != null' [: Lexical error at line 1, column 20.  Encountered: <EOF> after : ""]

Check that there is indeed a problem here

<if test="createDate != null'">#{createDate},</if>
