java - 使用 SuperDevMode 的打印堆栈跟踪被混淆了

Question

我有这段代码来处理 GWT 未捕获的异常:

    GWT.setUncaughtExceptionHandler(new GWT.UncaughtExceptionHandler() {
        @Override
        public void onUncaughtException(Throwable throwable) {
            // Iterate over the trace and then print with $wnd.console.log
            printStackTrace(throwable.getStackTrace());
        }
    });

但是在浏览器控制台打印的日志是这样的:

"Unknown.Ol(Unknown Source)
Unknown.Nl(Unknown Source)
Unknown.Vl(Unknown Source)
Unknown.Hu(Unknown Source)
Unknown.Ku(Unknown Source)
Unknown.ju(Unknown Source)
Unknown.h6(Unknown Source)
Unknown.As(Unknown Source)
Unknown.j6(Unknown Source)
Unknown.u6(Unknown Source)
Unknown.L3(Unknown Source)
Unknown.k5(Unknown Source)
Unknown.hn(Unknown Source)
Unknown.mn(Unknown Source)
Unknown.ln/<(Unknown Source)
Unknown.anonymous(Unknown Source)

我怎样才能让它像旧的 GWT 样式一样显示实际的堆栈跟踪？

这对我有用，请记住它并不完美，但它会在堆栈跟踪中为您提供文件和行号。是的，这适用于 gwt 2.7 和 super 开发模式。您需要将其添加到您的 *.gwt.xml 文件中。您可能希望在生产环境中关闭此功能，因为它会增加相当多的代码膨胀，但会使调试变得简单得多。
