Answer 1

Use Throwable.printStackTrace(PrintWriter pw) to send the stack trace to an appropriate writer.

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

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);
