tomcat8 idea调试时,静态资源有时能加载有时不能加载

通过对比成功加载和加载失败的请求,发现了一处不同的地方

加载失败的时候访问方式是 if-none-match.

经过网上翻阅资料,是tomcat8对静态资源的访问方式导致的.

最后在代码里加入了判断解决这个问题

 

public class XssHttpServletRequestWrapper extends HttpServletRequestWrapper {


	HttpServletRequest orgRequest = null;

	public XssHttpServletRequestWrapper(HttpServletRequest request) {
		super(request);
		orgRequest = request;
	}

	@Override
	public String getHeader(String name) {
		if("If-None-Match".equals(name)){
			return super.getHeader(name) != null ? super.getHeader(name).replace(""","\"") : null;
		}
		return StringEscapeUtils.escapeHtml4(super.getHeader(name));
	}


}
