配置querySql参数，sql不能以 ; 结尾

"connection": [
{
"querySql": [
"select db_id,on_line_flag from db_info where db_id < 10;"
],
"jdbcUrl": [
"jdbc:mysql://bad_ip:3306/database",
"jdbc:mysql://127.0.0.1:bad_port/database",
"jdbc:mysql://127.0.0.1:3306/database"
]
}
]

Start by locating DataX's handling of the connection.querySql configuration and reproduce the issue with the provided MySQL JDBC URLs and a query ending in a semicolon. Done means a querySql value ending in ';' is accepted, with the relevant existing test or configuration path confirming the behavior.
