获取完整的字符串堆栈跟踪，包括内部异常

获取完整的字符串堆栈跟踪，包括内部异常

我最终滚动了自己的代码（我采用了Throwable.printStackTrace（）的实现，并对其进行了一些调整）：

public static String joinStackTrace(Throwable e) {    StringWriter writer = null;    try {        writer = new StringWriter();        joinStackTrace(e, writer);        return writer.toString();    }    finally {        if (writer != null) try {     writer.close(); } catch (IOException e1) {     // ignore }    }}public static void joinStackTrace(Throwable e, StringWriter writer) {    PrintWriter printer = null;    try {        printer = new PrintWriter(writer);        while (e != null) { printer.println(e); StackTraceElement[] trace = e.getStackTrace(); for (int i = 0; i < trace.length; i++)     printer.println("tat " + trace[i]); e = e.getCause(); if (e != null)     printer.println("Caused by:rn");        }    }    finally {        if (printer != null) printer.close();    }}
