java - 如何不在控制台上打印异常

Question

我实现了自己的自定义异常。我不希望它在框架控制台上打印异常。是否可以？

May 15, 2017 2: 47: 24 PM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet[project - services] in context with path[/project-services] threw exception [Request processing failed; nested exception is ba.project.exception.TAException: There is no any tour activity between selected dates.] with root cause ba.project.exception.TAException: There is no any tour activity between selected dates.at ba.project.service.TAServices.findByTourTypeWithDates(TAServices.java: 94)

自定义异常:

 public class TAException extends RuntimeException {

  private static final long serialVersionUID = 1 L;

  public TAException(String msg) {
    super(msg);
  }

  public TAException(String msg, Throwable e) {
    super(msg, e);
  }
}

这是我抛出异常的方法:

public List < Object > findByTourTypeWithDates(String tourType, Date checkin, Date checkout)
throws ParseException, TAException {
  SimpleDateFormat dateFormatter = new SimpleDateFormat("yyyy-MM-dd");

  Date todayDate = dateFormatter.parse(dateFormatter.format(new Date()));
  if (checkin.after(todayDate)) {
    return taDAO.findByTourTypeWithDates(tourType, checkin, checkout);
  }
  throw new TAException("There is no any tour activity between selected dates.");
}

看一下Java异常规范

https://docs.oracle.com/javase/7/docs/api/java/lang/Exception.html

我认为您正在搜索的是 writableStackTrace，如果需要，您可以将其设置为 false。或者您可以重写 getMessage 以检查您所在的包或类似的内容。这取决于您的具体需求。
