mysql报错：Cause: java.sql.SQLException: sql injection violation, syntax error: syntax error, error in

错误描述：

Error updating database.Cause: java.sql.SQLException: sql injection violation, syntax error: syntax error, error in :'     uuid_filename = ? 
           ', expect IDENTIFIER, actual IDENTIFIER pos 260, line 11, column 35, token IDENTIFIER uuid_filename : 
           UPDATE mes_file_treefile
             SET file_name = ?,
                    modify_time = ?,
                    status = ?
                    uuid_filename = ? 
            where id = ?

解决：就是在某行的后面少加了一个逗号 ，加上就好了

<update id="updateTreeFiles">
   <if test="id != null" >
        UPDATE mes_file_treefile
        <set>
            <if test="file_name != null and file_name != '' ">
                file_name = #{file_name},
            </if>
            <if test="modify_time != null ">
                modify_time = #{modify_time},
            </if>
            <if test="status != null ">
                status = #{status}  //这里少加了一个逗号
            </if>
            <if test="uuid_filename != null and uuid_filename != '' ">
                uuid_filename = #{uuid_filename}
            </if>
        </set>
        where id = #{id}
    </if>
</update>
