我们有一些使用 Spring REST 端点的移动应用程序。由于一些有问题的应用程序，我们ClientAbortException在服务器上看到了。现在的问题是，这不是通过可配置的日志记录机制记录的——但显然只是写入控制台，导致各种问题。
因此，鉴于下面的堆栈跟踪，它甚至不包含我们自己的代码，我如何找出这个异常的打印位置？我已经尝试了以下方法：
- 我为 Spring 添加了一个特定的错误处理程序。这是因为调用了错误处理程序——但堆栈跟踪仍然被打印出来。
@ExceptionHandler(ClientAbortException.class)
@ResponseStatus(HttpStatus.SERVICE_UNAVAILABLE)
public Object exceptionHandler(ClientAbortException exc) {
return null; //socket is closed, cannot return any response
}
Throwable.printStackTrace我尝试在各种方法中设置断点。似乎没有一个被调用。我
PrintStream通过委托模式实现了一个自定义，并使用System.setErr(debuggablePrintStream);and进行了设置System.setOut(debuggablePrintStream);。同样，println似乎没有调用各种方法。
因此，除了使用Java 代理直接操作某些最终类的字节码外，我已经没有其他选择了。然后我最好从哪里开始？
这是不断充斥我们控制台的令人讨厌的堆栈跟踪：
