Method Details

build

public H2ConnectionConfiguration build()

Returns a configured H2ConnectionConfiguration.

Returns:

a configured H2ConnectionConfiguration

file

public H2ConnectionConfiguration.Builder file(String path)

Configure a file-based database, e.g. ~/my-database or /path/to/my/database.db.

Parameters:

path - of the database file (automatically prefixed with file:)

Returns:

this H2ConnectionConfiguration.Builder

inMemory

public H2ConnectionConfiguration.Builder inMemory(String name)

Configure an in-memory database, e.g. my-test-database.

A in-memory database is shut down if the last connection gets closed. To avoid this behavior, configure either the H2ConnectionOption.DB_CLOSE_DELAY option through property(H2ConnectionOption, String) or use the H2ConnectionFactory.inMemory(String) connection factory to close the in-memory database by closing CloseableConnectionFactory externally.

Parameters:

name - of a private, in-memory database (automatically prefixed with mem:)

Returns:

this H2ConnectionConfiguration.Builder

tcp

public H2ConnectionConfiguration.Builder tcp(String host,
 String path)

Configure a TCP connection to a remote database.

Parameters:

host - - hostname of the remote database (can be localhost)

path - - path of the database, e.g. ~/test resolves to {user.home}/test.db

Returns:

this H2ConnectionConfiguration.Builder

tcp

public H2ConnectionConfiguration.Builder tcp(String host,
 int port,
 String path)

Configure a TCP connection to a remote database

Parameters:

host - - hostname of the remote database (can be localhost)

port - - port the database is serving from

path - - path of the database, e.g. ~/test resolves to {user.home}/test.db

Returns:

this H2ConnectionConfiguration.Builder

option

public H2ConnectionConfiguration.Builder option(String option)

Configure an option that is appended at the end, e.g. DB_CLOSE_DELAY=10, prefixed with ";".

Parameters:

option - to append at the end using a ; prefix.

Returns:

this H2ConnectionConfiguration.Builder

property

Returns:

this H2ConnectionConfiguration.Builder

password

public H2ConnectionConfiguration.Builder password(@Nullable
 CharSequence password)

Configure the password.

Parameters:
