@Component//泛指組件，當組件不好歸類的時候，我們可以使用這個注解進行標注
public class LogUtil {

@Autowired
//注意這里非靜態
private AdminLogService logService;

private static LogUtil logUtil;

@PostConstruct //@PostConstruct修飾的方法會在服務器加載Servle的時候運行，並且只會被服務器執行一次。PostConstruct在構造函數之后執行,init()方法之前執行
public void init() { 
logUtil = this; 
logUtil.logService = this.logService; 
} 
public AdminLogService getUserService() {
return logService;
}
public void setUserService(AdminLogService userService) {
this.logService = userService;
}
public static void addLog(LoginInfo loginInfo,String desc){
//添加日志
AdminLog log=new AdminLog();
log.setCreatetime(new Date());
log.setDescription(desc);
try {
log.setCuid(loginInfo.getUser().getId());
log.setCreateuser(loginInfo.getUser().getAccount());
logUtil.logService.insertLog(log);
} catch (Exception e) {
log.setCuid(0);
log.setCreateuser("unknow");
//調用時通過類去調
logUtil.logService.insertLog(log);
}

}
}
