方法详细资料

getConnection

public Connection getConnection()
                         throws SQLException

Attempts to establish a connection with the data source that this DataSource object represents.

指定者:

getConnection 在接口中 DataSource

返回:

a connection to the data source

抛出:

SQLException - if a database access error occurs

SQLTimeoutException - when the driver has determined that the timeout methodName specified by the setLoginTimeout method has been exceeded and has at least tried to cancel the current database connection attempt

getConnection

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

Attempts to establish a connection with the data source that this DataSource object represents.

指定者:

getConnection 在接口中 DataSource

参数:

username - the database user on whose behalf the connection is being made

password - the user's password

返回:

a connection to the data source

抛出:

SQLException - if a database access error occurs

SQLTimeoutException - when the driver has determined that the timeout methodName specified by the setLoginTimeout method has been exceeded and has at least tried to cancel the current database connection attempt

getConnection

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

抛出:

SQLException

unwrap

public <T> T unwrap(Class<T> iface)
             throws SQLException

Returns an object that implements the given interface to allow access to non-standard methods, or standard methods not exposed by the proxy.

If the receiver implements the interface then the result is the receiver or a proxy for the receiver. If the receiver is a wrapper and the wrapped object implements the interface then the result is the wrapped object or a proxy for the wrapped object. Otherwise return the the result of calling unwrap recursively on the wrapped object or a proxy for that result. If the receiver is not a wrapper and does not implement the interface, then an SQLException is thrown.

指定者:

unwrap 在接口中 Wrapper

参数:

iface - A Class defining an interface that the result must implement.

返回:

an object that implements the interface. May be a proxy for the actual implementing object.

抛出:

SQLException - If no object found that implements the interface

从以下版本开始:

1.6

isWrapperFor

public boolean isWrapperFor(Class<?> iface)
                     throws SQLException

Returns true if this either implements the interface argument or is directly or indirectly a wrapper for an object that does. Returns false otherwise. If this implements the interface then return true, else if this is a wrapper then return the result of recursively calling isWrapperFor on the wrapped object. If this does not implement the interface and is not a wrapper, return false. This method should be implemented as a low-cost operation compared to unwrap so that callers can use this method to avoid expensive unwrap calls that may fail. If this method returns true then calling unwrap with the same argument should succeed.

指定者:

isWrapperFor 在接口中 Wrapper

参数:

iface - a Class defining an interface.

返回:

true if this implements the interface or directly or indirectly wraps an object that does.

抛出:

SQLException - if an error occurs while determining whether this is a wrapper for an object with the given interface.

getLogWriter

public PrintWriter getLogWriter()
                         throws SQLException

Retrieves the log writer for this DataSource object.

The log writer is a character output stream to which all logging and tracing messages for this data source will be printed. This includes messages printed by the methods of this object, messages printed by methods of other objects manufactured by this object, and so on. Messages printed to a data source specific log writer are not printed to the log writer associated with the java.sql.DriverManager class. When a DataSource object is created, the log writer is initially null; in other words, the default is for logging to be disabled.

指定者:

getLogWriter 在接口中 CommonDataSource

指定者:

getLogWriter 在接口中 DataSource

返回:

the log writer for this data source or null if logging is disabled

抛出:

SQLException - if a database access error occurs

1.4

• setLogWriter(java.io.PrintWriter)

setLogWriter

public void setLogWriter(PrintWriter out)
                  throws SQLException

Sets the log writer for this DataSource object to the given java.io.PrintWriter object.

The log writer is a character output stream to which all logging and tracing messages for this data source will be printed. This includes messages printed by the methods of this object, messages printed by methods of other objects manufactured by this object, and so on. Messages printed to a data source- specific log writer are not printed to the log writer associated with the java.sql.DriverManager class. When a DataSource object is created the log writer is initially null; in other words, the default is for logging to be disabled.

指定者:

setLogWriter 在接口中 CommonDataSource

指定者:

setLogWriter 在接口中 DataSource

参数:

out - the new log writer; to disable logging, set to null

抛出:

SQLException - if a database access error occurs

从以下版本开始:

1.4

getLoginTimeout

public int getLoginTimeout()
                    throws SQLException

Gets the maximum time in seconds that this data source can wait while attempting to connect to a database. A methodName of zero means that the timeout is the default system timeout if there is one; otherwise, it means that there is no timeout. When a DataSource object is created, the login timeout is initially zero.

指定者:

getLoginTimeout 在接口中 CommonDataSource

指定者:

getLoginTimeout 在接口中 DataSource

返回:

the data source login time limit

抛出:

SQLException - if a database access error occurs.

• setLoginTimeout(int)

setLoginTimeout

public void setLoginTimeout(int seconds)
                     throws SQLException

Sets the maximum time in seconds that this data source will wait while attempting to connect to a database. A methodName of zero specifies that the timeout is the default system timeout if there is one; otherwise, it specifies that there is no timeout. When a DataSource object is created, the login timeout is initially zero.

指定者:

setLoginTimeout 在接口中 CommonDataSource

指定者:

setLoginTimeout 在接口中 DataSource

参数:

seconds - the data source login time limit

抛出:

SQLException - if a database access error occurs.

getParentLogger

public Logger getParentLogger()
                       throws SQLFeatureNotSupportedException

Return the parent Logger of all the Loggers used by this data source. This should be the Logger farthest from the root Logger that is still an ancestor of all of the Loggers used by this data source. Configuring this Logger will affect all of the log messages generated by the data source. In the worst case, this may be the root Logger.

指定者:

getParentLogger 在接口中 CommonDataSource

返回:

the parent Logger for this data source

抛出:

SQLFeatureNotSupportedException - if the data source does not use java.util.logging

从以下版本开始:

1.7

afterPropertiesSet

public void afterPropertiesSet()
                        throws Exception
