Get and Load methods for session in Hibernate

Both session and get are data used to get objects, but there are some differences in use.

1. Get in use queries the first-level cache, but if there is no hit, the SQL statement is submitted to the database for re-querying.

2. When load is in use, the first level cache is queried, and if there is no hit, a level two cache is queried, and if there is still no hit, the query is submitted back to the database for execution.

3. Load supports lazy loading, but get not.

4. If get does not query the result, a null value is returned. If the load does not query the result, the exception information objectnotfoundexception will be thrown.

In Hibernate, the session level is usually the first level cache, the sessionfactory level is a level two cache, where the level two cache needs to be opened extra.
