java - 是否可以在没有堆栈跟踪的情况下抛出自定义异常？

问题描述

在我的应用程序中，我使用 AngularJS 作为前端，使用 Java 作为后端。每当我需要在前端面板中显示自定义错误时，我都会使用自定义异常从 Java 中抛出，在 Angular 中，我将得到它作为响应并使用 javascript 构建消息。此自定义异常是一种常见异常，因此在服务器日志中，正在捕获整个堆栈跟踪。我处于应该存在 throw 并且不应该打印堆栈跟踪的情况。我想到了。但是，在抛出之后，当它需要在抛出后实际停止时，它会继续事务。有很多复杂的代码，我只在需要时粘贴必要的代码。

 List<GenericException> failedValidations = new ArrayList<>();
 if (CollectionUtils.isNotEmpty(failedValidations)) {
        String failedValidationErrorCode = Util.convertListToString(failedValidations.stream().map(GenericException::getCode).collect(Collectors.toList()));
        throw new ReservationException("Exception thrown with error codes :"+ failedValidationErrorCode, failedValidations);
    }

现在，当这个错误被抛出时，

考虑在服务器日志中一天打印 1000 次。我只需要在服务器日志中打印第一行。那是，

 com.abc.def.exceptions.ReservationException: Exception thrown with error codes :5965

如果只有错误代码，那对于调试来说已经绰绰有余了。我知道这是一个很长的问题，请帮助我解决这个问题。

解决方案

您已经在使用 spring mvc（请参阅包含 spring mvc 类的堆栈跟踪）

如果是这样，最好的选择可能是在 Contoller Advice 级别或spring MVC 支持的任何其他异常处理机制级别捕获异常。

基本上堆栈跟踪仅在没有人（控制器、建议或服务）捕获它的情况下由 spring mvc 引擎本身打印。

从角度来看，没有例外。相反，您会使用一些默认 JSON 获得非 200 状态，这是 HTTP 格式的响应，不是例外，而只是某种特定类型的响应。所以我相信最好的办法是为到达客户端的消息建立一些协议，显然服务器堆栈跟踪不是要发送给客户端的东西。

这是一种约定，可能包括：

  1. HTTP 状态（非 200 以区分错误和常规答案）
  2. 预定义格式的 JSONmessage：
  • 异常 ID
  • 服务器上的时间
  • 信息
  • 客户端映射的参数
  • I18n 相关信息（如果与您的申请相关）。

长话短说：

  • 您创建一个控制器建议并在那里映射自定义异常
  • 映射方法将创建一个“协议”json 并将其返回给 angular。
  • 如果之前没有人捕获到异常，spring 会自动调用这个映射方法。
  • 由于映射方法将处理异常，因此它不会打印在服务器的控制台上，这正是您想要实现的。
  • 客户端将获取 json 并将创建一些处理所有消息的角度“基础设施”代码（可能在屏幕顶部显示消息，弹出任何内容）。
