The service can manage a number of connection pools. Each pool is related to a specific database, identified by it's driver class name, url, username and password. The pools may be defined in TurbineResources.properties file, or created at runtime using <CODE>#registerPool(String,String,String,String,String)</CODE> method. <p> You can use <A HREF="../../../../../org/apache/turbine/services/db/PoolBrokerService.html#getConnection(java.lang.String)"><CODE>getConnection(String)</CODE></A> to acquire a <CODE>org.apache.turbine.util.db.pool.DBConnection</CODE> object, which in turn can be used to create <code>java.sql.Statement</code> objects. <p>When you are done using the <code>DBConnection</code> you <strong>must</strong> return it to the pool using <CODE>#releaseConnection(DBConnection)</CODE> method. This method call is often placed in <code>finally</code> clause of a <code>try / catch</code> statement, to ensure that the connection is always returned to the pool.<br><P><DL><DT><B>Version: </B><DD>$Id: PoolBrokerService.java,v 1.4 2002/07/12 20:46:55 mpoeschl Exp $</DD><DT><B>Author: </B><DD><a href="mailto:Rafal.Krzewski@e-point.pl">Rafal Krzewski</a></DD></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/db/PoolBrokerService.html#DEFAULT">DEFAULT</A></B></CODE><BR> <B>Deprecated.</B> the name of the default pool</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/db/PoolBrokerService.html#DEFAULT_POOL">DEFAULT_POOL</A></B></CODE><BR> <B>Deprecated.</B> Name of default pool property</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/db/PoolBrokerService.html#SERVICE_NAME">SERVICE_NAME</A></B></CODE><BR> <B>Deprecated.</B> the name of the service</TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.sql.Connection</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/db/PoolBrokerService.html#getConnection()">getConnection</A></B>()</CODE><BR> <B>Deprecated.</B> This method returns a DBConnection from the default pool.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.sql.Connection</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/db/PoolBrokerService.html#getConnection(java.lang.String)">getConnection</A></B>(java.lang.String name)</CODE><BR> <B>Deprecated.</B> This method returns a DBConnection from the pool with the specified name.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> org.apache.torque.adapter.DB</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/db/PoolBrokerService.html#getDB()">getDB</A></B>()</CODE><BR> <B>Deprecated.</B> Returns the database adapter for the default connection pool.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> org.apache.torque.adapter.DB</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/db/PoolBrokerService.html#getDB(java.lang.String)">getDB</A></B>(java.lang.String name)</CODE><BR> <B>Deprecated.</B> Returns database adapter for a specific connection pool.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/db/PoolBrokerService.html#getDefaultDB()">getDefaultDB</A></B>()</CODE><BR> <B>Deprecated.</B> Return default DB</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/apache/turbine/services/db/PoolBrokerService.html#releaseConnection(java.sql.Connection)">releaseConnection</A></B>(java.sql.Connection dbconn)</CODE><BR> <B>Deprecated.</B> Release a connection back to the database pool.</TD></TR></TABLE> <A NAME="methods_inherited_from_class_org.apache.turbine.services.Service"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor">⌨️ 快捷键说明
