Connection cannot be null when 'hibernate.dialect' not set

Question

having more issues with seting up hibernate with spring3. this time it is saying that connection is nul as the dialect is not set which it is on my hibernate.cfg.xml file.

Answer 1

We were recently facing the same issue with one of our deployment, as we were also using hibernate and dialect is null is a vague error. I use was with connection string itself and did the changes below to make it work

connectionUrl :- jdbc:mysql://127.0.0.1:3306/{{dbName}}?serverTimezone=UTC&allowPublicKeyRetrieval=true&useSSL=false

Steps how did we solve it 1) We ran simple DB connection with JDBC driver that will gave the exception of time zone. 2) we found the issue with time zone and had to add more properties in connection string as show above. 3) We also added 2 other properties as still it was not working.

Dialect is not set is vague to took lot of our time, I hope this helps.
