将堆栈跟踪转换为字符串？

Question

是否可以在GWT中将堆栈跟踪打印到字符串？我认为在java.io中使用类的常用方法不起作用,因为java.io包在客户端不可用(而Writer,PrintWriter等在该包中)

谢谢

Answer 1

我不确定StackTraceElement是否被模拟,但如果是,你可以运行类似的东西

for (StackTraceElement element : exception.getStackTrace()) {
    string += element + "\n";
}

Answer 2

这是我用来String在GWT中检索完整堆栈跟踪的方法:

private static String getMessage (Throwable throwable) {
    String ret="";
    while (throwable!=null) {
            if (throwable instanceof com.google.gwt.event.shared.UmbrellaException){
                    for (Throwable thr2 :((com.google.gwt.event.shared.UmbrellaException)throwable).getCauses()){
                            if (ret != "")
                                    ret += "\nCaused by: ";
                            ret += thr2.toString();
                            ret += "\n  at "+getMessage(thr2);
                    }
            } else if (throwable instanceof com.google.web.bindery.event.shared.UmbrellaException){
                    for (Throwable thr2 :((com.google.web.bindery.event.shared.UmbrellaException)throwable).getCauses()){
                            if (ret != "")
                                    ret += "\nCaused by: ";
                            ret += thr2.toString();
                            ret += "\n  at "+getMessage(thr2);
                    }
            } else {
                    if (ret != "")
                            ret += "\nCaused by: ";
                    ret += throwable.toString();
                    for (StackTraceElement sTE : throwable.getStackTrace())
                            ret += "\n  at "+sTE;
            }
            throwable = throwable.getCause();
    }

    return ret;
}
