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


当前回答

public static String getStackTrace(Throwable t) {
    StringWriter sw = new StringWriter();
    t.printStackTrace(new PrintWriter(sw));
    return sw.toString();
}

对我来说,最干净、最简单的方法是:

import java.util.Arrays;
Arrays.toString(e.getStackTrace());
Arrays.toString(thrown.getStackTrace())

是将结果转换为字符串的最简单方法我在程序中使用这个来打印堆栈跟踪

LOGGER.log(Level.SEVERE, "Query Builder Issue Stack Trace : {0} ,Message : {1} objid {2}", new Object[]{Arrays.toString(e.getStackTrace()), e.getMessage(),objId});

如果你是为Android开发的,一个更简单的方法是使用这个:

import android.util.Log;

String stackTrace = Log.getStackTraceString(exception); 

格式与getStacktrace相同,例如。

如果您有实际的Throwables实例,GoogleGuava提供Throwables.getStackTraceAsString()。

例子:

String s = Throwables.getStackTraceAsString ( myException ) ;

将堆栈跟踪打印到PrintStream,然后将其转换为字符串:

// ...

catch (Exception e)
{
    ByteArrayOutputStream out = new ByteArrayOutputStream(); 
    e.printStackTrace(new PrintStream(out));
    String str = new String(out.toByteArray());

    System.out.println(str);
}
