public void setUrl(@Nullable
 String url)

Set the JDBC URL to use for connecting through the Driver.

See Also:

• Driver.connect(String, java.util.Properties)

getUrl

@Nullable
public String getUrl()

Return the JDBC URL to use for connecting through the Driver.

setUsername

public void setUsername(@Nullable
 String username)

Set the JDBC username to use for connecting through the Driver.

See Also:

• Driver.connect(String, java.util.Properties)

getUsername

@Nullable
public String getUsername()

Return the JDBC username to use for connecting through the Driver.

setPassword

public void setPassword(@Nullable
 String password)

Set the JDBC password to use for connecting through the Driver.

See Also:

• Driver.connect(String, java.util.Properties)

getPassword

@Nullable
public String getPassword()

Return the JDBC password to use for connecting through the Driver.

setCatalog

public void setCatalog(@Nullable
 String catalog)

Specify a database catalog to be applied to each Connection.

Since:

4.3.2

See Also:

• Connection.setCatalog(java.lang.String)

getCatalog

@Nullable
public String getCatalog()

Return the database catalog to be applied to each Connection, if any.

Since:

4.3.2

setSchema

public void setSchema(@Nullable
 String schema)

Specify a database schema to be applied to each Connection.

Since:

4.3.2

See Also:

• Connection.setSchema(java.lang.String)

getSchema

@Nullable
public String getSchema()

setConnectionProperties

public void setConnectionProperties(@Nullable
 Properties connectionProperties)

Specify arbitrary connection properties as key/value pairs, to be passed to the Driver.

Can also contain "user" and "password" properties. However, any "username" and "password" bean properties specified on this DataSource will override the corresponding connection properties.

See Also:

• Driver.connect(String, java.util.Properties)

getConnectionProperties

@Nullable
public Properties getConnectionProperties()

Return the connection properties to be passed to the Driver, if any.

getConnection

public Connection getConnection()
                         throws SQLException

This implementation delegates to getConnectionFromDriver, using the default username and password of this DataSource.

Throws:

SQLException

See Also:

• getConnectionFromDriver(String, String)
• setUsername(java.lang.String)
• setPassword(java.lang.String)

getConnection

public Connection getConnection(String username,
 String password)
                         throws SQLException

This implementation delegates to getConnectionFromDriver, using the given username and password.

Throws:

SQLException

See Also:

• getConnectionFromDriver(String, String)

getConnectionFromDriver

protected Connection getConnectionFromDriver(@Nullable
 String username,
 @Nullable
 String password)
                                      throws SQLException

Build properties for the Driver, including the given username and password (if any), and obtain a corresponding Connection.

Parameters:

username - the name of the user

password - the password to use

Returns:

the obtained Connection

Throws:

SQLException - in case of failure

See Also:

• Driver.connect(String, java.util.Properties)

getConnectionFromDriver

protected abstract Connection getConnectionFromDriver(Properties props)
                                               throws SQLException

Obtain a Connection using the given properties.

Template method to be implemented by subclasses.

Parameters:

props - the merged connection properties

Returns:

the obtained Connection
