在quickfix包中，类SessionSettings有一个构造函数来加载配置文件。

然后你应该能够使用set方法修改你想要的东西。

例如，要仅为特定会话更改主机：

final SessionSettings ss = new SessionSettings( "session.cfg" );

for( final Iterator<SessionID> i = ss.sectionIterator(); i.hasNext(); ) {
    final SessionID id = i.next();
    if( id.getSenderCompID().startsWith("quote") )
        ss.setString( id, "SocketConnectHost", "123.101.202.010" );
}
