Answer 1

zloiadun给出的答案在这里不起作用,而是我必须使用,

Logger logger = Logger.getLogger ("");
logger.setLevel (Level.OFF);

..根据需要更改getLogger(..)和级别.

Answer 2

虽然这些东西都不适用于我,但我发现我可以通过制作一个自定义错误处理程序来关闭HTMLUnit ......这有点俗气......但是如果你需要它它会给你很好的控制:

        webClient.setCssErrorHandler(new ErrorHandler() {
        //Saint
        @Override
        public void warning(CSSParseException arg0) throws CSSException {
            // stare blankly

        }

        @Override
        public void fatalError(CSSParseException arg0) throws CSSException {
            // twiddle thumbs

        }

        @Override
        public void error(CSSParseException arg0) throws CSSException {
            // drool on shirt

        }
    });
