The difference between get and load in hibernate

Source: Internet
Author: User

The Session.load/get method can read records from the database based on the specified entity class and ID and return the entity object corresponding to it.

The difference is:

1. If a record that meets the criteria cannot be found, the Get method returns NULL, and the load method throws a objectnotfoundexception.

2. The Load method returns an instance of the proxy class for the entity, and the Get method returns the entity class forever.

3, the Load method can make full use of the internal cache and the two-level cache of existing data, while the Get method is only in the internal cache for data lookup, if not found to meet the conditions of data, will be over the level two cache, directly invoke SQL to complete data reading.
