Thymeleaf Error resolving template [favicon.ico]

每一个看似简单的社会现象其实都只露出了冰山一角。——林达

遇到这个报错，方案1：

在页面上添加：

1
<link rel="icon" href="/static/favicon.ico">

前提是你有icon并且放到了static下面

方案2：

写个过滤器，给它过滤掉

        String uri = httpRequest.getRequestURI();

            return;
        }
        chain.doFilter(request, response);
    }
}

方案3:

写一个接口,返回空
