我做了一个愚蠢的技巧来完成这项工作！如果您有更好的解决方案，请告诉我.

I make a silly hack to get this work done! If you have a better solution, tell me.

package org.eclipse.jetty.server.handler;

import javax.servlet.http.HttpServletResponse;

import org.eclipse.jetty.http.HttpHeaders;
import org.eclipse.jetty.util.resource.Resource;
/**

public class StaticResourceHandler extends ResourceHandler{
    private String expires = "xxx";

    @Override
    protected void doResponseHeaders(HttpServletResponse response, Resource resource, String mimeType) {
        super.doResponseHeaders(response, resource, mimeType);
        response.setHeader(HttpHeaders.EXPIRES, expires);
    }
}
