Hibernate Session Object Load () method differs from Get () method

(1) When the record does not exist, the Get method returns the Null,load method to produce an exception

(2) The Load method can return the proxy class of the entity, and the Get method returns the true entity class

(3) The Load method can take advantage of the hibernate internal cache and the existing data in level two cache, while the Get method only looks for data in the internal cache, and when the appropriate data is not found in the cache, the SQL query database is generated and the corresponding entity object is returned
