java - 如何将堆栈跟踪转换为字符串？

Question

将 Throwable.getStackTrace() 的结果转换为描述堆栈跟踪的字符串的最简单方法是什么？

Answer 1

使用Throwable.printStackTrace(PrintWriter pw)将堆栈跟踪发送给适当的编写器。

import java.io.StringWriter;
import java.io.PrintWriter;

// ...

StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
e.printStackTrace(pw);
String sStackTrace = sw.toString(); // stack trace as a string
System.out.println(sStackTrace);
