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？

One can use the following method to convert an Exception stack trace to String . This class is available in Apache commons-lang which is most common dependent library with many popular open sources

org.apache.commons.lang.exception.ExceptionUtils.getStackTrace(Throwable)

使用Throwable.printStackTrace（PrintWriter pw）将堆栈跟踪发送到适当的写入器。

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);

这应该工作：

StringWriter sw = new StringWriter();
e.printStackTrace(new PrintWriter(sw));
String exceptionAsString = sw.toString();
