用Throwable.printStackTrace(PrintWriter pw)可以输出堆栈信息: StringWriter sw = new StringWriter(); PrintWriter pw = new PrintWriter(sw); t.printStackTrace(pw); sw.toString(); // stack trace as a string 答案三 StringWriter sw = new StringWriter(); e.printStackTrace(new PrintWriter(sw)); Stri...
现在使用异常的printStackTrace()方法打印堆栈跟踪,然后将其写入编写器。最后,使用toString()方法将其转换为字符串。 执行: Java // Java Program to convert a Stack trace to a string import java.io.*; public class PrintStackTrace { public static void main(String[] args) { try { int a[] = new...
以下示例显示了java.lang.Throwable.printStackTrace()方法的用法。 package com.wenjiangs; import java.lang.*; public class ThrowableDemo { public static void main(String[] args) throws Throwable { OutputStream out; try { ExceptionFunc(); } catch(Throwable e) { out = new FileOutputStream("file...
To be clear, you don’t need this approach when using things likeSystem.out.printlnorSystem.err.println; you can just usee.printStackTracethere, which prints to STDERR. But when you want to write to a logger, or otherwise convert a stack trace to a string, the second approach work...
Java异常的栈轨迹(Stack Trace) 捕获到异常时,往往需要进行一些处理。比较简单直接的方式就是打印异常栈轨迹Stack Trace。说起栈轨迹,可能很多人和我一样,第一反应就是printStackTrace()方法。其实除了这个方法,还有一些别的内容也是和栈轨迹有关的。 1.printStackTrace() ...

Java program to convert error stack trace to String. StackTrace to String conversion may be useful to print stack trace in custom logs.
public class ThrowableDemo { public static void main(String[] args) throws Throwable { OutputStream out; try { ExceptionFunc(); } catch(Throwable e) { out = new FileOutputStream("file.text"); // prints this throwable and its backtrace to the print stream PrintStream ps = new PrintStream...
String s; … t.printStackTrace(pw); s = sw.toString(); sw.getBuffer().setLength(0); …. // 这里的代码省略 } [/code] 这里我们可以看到整体的实现思路。 首先,t.printStackTrace(pw); 获得stack trace字符串。这个t是 new Throwable()的结果。用户程序调用Log4J方法之后,Log4J自己又进行了4次调用...
