AbstractMultiTenantConnectionProvider

public AbstractMultiTenantConnectionProvider()

方法详细资料

getAnyConnectionProvider

protected abstract ConnectionProvider getAnyConnectionProvider()

selectConnectionProvider

protected abstract ConnectionProvider selectConnectionProvider(String tenantIdentifier)

getAnyConnection

public Connection getAnyConnection()
                            throws SQLException

从接口复制的说明: MultiTenantConnectionProvider

Allows access to the database metadata of the underlying database(s) in situations where we do not have a tenant id (like startup processing, for example).

指定者:

getAnyConnection 在接口中 MultiTenantConnectionProvider

返回:

The database metadata.

抛出:

SQLException - Indicates a problem opening a connection

releaseAnyConnection

public void releaseAnyConnection(Connection connection)
                          throws SQLException

从接口复制的说明: MultiTenantConnectionProvider

Release a connection obtained from MultiTenantConnectionProvider.getAnyConnection()

指定者:

releaseAnyConnection 在接口中 MultiTenantConnectionProvider

参数:

connection - The JDBC connection to release

抛出:

SQLException - Indicates a problem closing the connection

getConnection

public Connection getConnection(String tenantIdentifier)
                         throws SQLException

从接口复制的说明: MultiTenantConnectionProvider

Obtains a connection for Hibernate use according to the underlying strategy of this provider.

指定者:

getConnection 在接口中 MultiTenantConnectionProvider

参数:

tenantIdentifier - The identifier of the tenant for which to get a connection

返回:

The obtained JDBC connection

抛出:

SQLException - Indicates a problem opening a connection

releaseConnection

public void releaseConnection(String tenantIdentifier,
                              Connection connection)
                       throws SQLException

从接口复制的说明: MultiTenantConnectionProvider

Release a connection from Hibernate use.

指定者:

releaseConnection 在接口中 MultiTenantConnectionProvider

参数:

tenantIdentifier - The identifier of the tenant.

connection - The JDBC connection to release

抛出:

SQLException - Indicates a problem closing the connection

supportsAggressiveRelease

public boolean supportsAggressiveRelease()

从接口复制的说明: MultiTenantConnectionProvider

Does this connection provider support aggressive release of JDBC connections and re-acquisition of those connections (if need be) later?

This is used in conjunction with AvailableSettings.RELEASE_CONNECTIONS to aggressively release JDBC connections. However, the configured ConnectionProvider must support re-acquisition of the same underlying connection for that semantic to work.

Typically, this is only true in managed environments where a container tracks connections by transaction or thread. Note that JTA semantic depends on the fact that the underlying connection provider does support aggressive release.

指定者:

supportsAggressiveRelease 在接口中 MultiTenantConnectionProvider

返回:

true if aggressive releasing is supported; false otherwise.

isUnwrappableAs

public boolean isUnwrappableAs(Class unwrapType)

从接口复制的说明: Wrapped

Can this wrapped service be unwrapped as the indicated type?

指定者:

isUnwrappableAs 在接口中 Wrapped

参数:

unwrapType - The type to check.

返回:

True/false.

unwrap

public <T> T unwrap(Class<T> unwrapType)

从接口复制的说明: Wrapped

Unproxy the service proxy

指定者:

unwrap 在接口中 Wrapped

参数:

unwrapType - The java type as which to unwrap this instance.

返回:

The unwrapped reference
