Steps to Reproduce:
In Order.java, run the function queryOrderByUsername() and addOrder(), we can see the return results of executions.

Expected output:
When executing the queryOrderByUsername() and addOrder(), when the result is not null, we will see rsToAl(rs), otherwise it will return null.

Actual output:
We can only get the rsToAl(rs) and when the rs==null, it fails.

Resolution:	
We should add if conditional sentences if(rs==null) in queryOrderByUsername() and addOrder() to judge whether the result is null.
