Parameters:

interceptor - The interceptor to use.

Returns:

noInterceptor

public SharedSessionBuilder noInterceptor()

Description copied from interface: CommonBuilder

Specifies that no Interceptor should be used.

By default, if no Interceptor is explicitly specified, the Interceptor associated with the SessionFactory is inherited by the new session. Or, if there is no interceptor associated with the SessionFactory, but a session-scoped interceptor has been configured, a new session-scoped Interceptor will be created for the new session.

Calling interceptor(null) has the same effect.

Returns:

this, for method chaining

Description copied from interface: CommonBuilder

Specifies that no session-scoped interceptor should be instantiated for the new session.

By default, if no Interceptor is explicitly specified, and if there is no interceptor associated with the SessionFactory, but a session-scoped interceptor has been configured, a new session-scoped Interceptor will be created for the new session.

Note that this operation does not disable use of an interceptor associated with the SessionFactory.

Specified by:

Parameters:

Returns:

this, for method chaining

readOnly

public SharedSessionBuilder readOnly(boolean readOnly)

Description copied from interface: CommonBuilder

Specify a read-only mode for the session. If a session is created in read-only mode, then Connection.setReadOnly(boolean) is called when a JDBC connection is obtained.

Furthermore, if read/write replication is in use, then:

• a read-only session will connect to a read-only replica, but
• a non-read-only session will connect to a writable replica.

When read/write replication is in use, it's strongly recommended that the session be created with the initial cache mode set to CacheMode.GET, to avoid writing stale data read from a read-only replica to the second-level cache. Hibernate cannot possibly guarantee that data read from a read-only replica is up to date.

When read/write replication is in use, it's possible that an item read from the second-level cache might refer to data which does not yet exist in the read-only replica. In this situation, an exception occurs when the association is fetched. To completely avoid this possibility, the initial cache mode must be set to CacheMode.IGNORE. However, it's also usually possible to structure data access code in a way which eliminates this possibility.

 try (var readOnlySession =
         sessionFactory.withOptions()
                 .readOnly(true)
                 .initialCacheMode(CacheMode.IGNORE)
                 .openSession()) {
     ...
 }
 

If a session is created in read-only mode, then it cannot be changed to read-write mode, and any call to Session.setDefaultReadOnly(boolean) with fail. On the other hand, if a session is created in read-write mode, then it may later be switched to read-only mode, but all database access is directed to the writable replica.
