新版的ACE已经取消了ACE_static_case宏的使用，直接使用static_cast做转换。针对此变化，对APG一书中关于47页的例子做了一改动：

#include "ace/streams.h"#include "ace/Log_Msg_Callback.h"#include "ace/Log_Record.h"#include "ace/SString.h"#include "ace/OS_NS_time.h"#include "ace/Time_Value.h"class Callback : public ACE_Log_Msg_Callback{public:void log(ACE_Log_Record &log_record){cerr << "Log Message Received:" << endl;unsigned long msg_severity = log_record.type();ACE_Log_Priority prio = static_cast<ACE_Log_Priority>(msg_severity);//(ACE_Log_Priority)msg_severity;const ACE_TCHAR *prio_name = ACE_Log_Record::priority_name(prio);cerr << "/tType: "<< ACE_TEXT_ALWAYS_CHAR(prio_name)<< endl;cerr << "/tLength: " << log_record.length() << endl;const time_t epoch = log_record.time_stamp().sec();cerr << "/tTime_Stamp: "<< ACE_TEXT_ALWAYS_CHAR(ACE_OS::ctime(&epoch))<< flush;cerr << "/tPid: " << log_record.pid() << endl;ACE_CString data(">> ");data += ACE_TEXT_ALWAYS_CHAR(log_record.msg_data());cerr << "/tMsgData: " << data.c_str() << endl;}};
