方法详细资料

executeWork

public <T> T executeWork(Work work,
                         Connection connection)
                  throws SQLException

Execute the discrete work encapsulated by a Work instance using the supplied connection. Because Work does not return a value when executed (via Work.execute(java.sql.Connection), this method always returns null.

参数:

work - The @link ReturningWork} instance encapsulating the discrete work

connection - The connection on which to perform the work.

返回:

null.

抛出:

SQLException - Thrown during execution of the underlying JDBC interaction.

HibernateException - Generally indicates a wrapped SQLException.

executeReturningWork

public <T> T executeReturningWork(ReturningWork<T> work,
                                  Connection connection)
                           throws SQLException

Execute the discrete work encapsulated by a ReturningWork instance using the supplied connection, returning the result of ReturningWork.execute(java.sql.Connection)

参数:

work - The @link ReturningWork} instance encapsulating the discrete work

connection - The connection on which to perform the work.

返回:

the valued returned by work.execute(connection).

抛出:

SQLException - Thrown during execution of the underlying JDBC interaction.

HibernateException - Generally indicates a wrapped SQLException.
