Я создал простой класс Filter, который добавляет некоторые заголовки ответов ко всем запрошенным ресурсам. Я создал файл jar и добавил его в папку lib tomcat. Также фильтр добавляется в Интернет. xml для сопоставления URL-адресов / *
Когда я запрашиваю страницу своего приложения, я вижу, что фильтр запускается, поскольку операторы sysout печатаются правильно, но заголовки получаются добавлены только к некоторым активам. Я не совсем понимаю, почему он добавляется только к некоторым активам, а не ко всем.
Класс фильтра, как показано ниже
package com.headers.config;
import java.io.IOException;

import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class MySecurityHeadersFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
chain.doFilter(request, response);
HttpServletRequest httpReq = (HttpServletRequest) request;
HttpServletResponse httpResp = (HttpServletResponse) response;
httpResp.addHeader("Content-Security-Policy", "default-src 'none'; script-src 'self'; connect-src 'self'; img-src 'self'; style-src 'self';base-uri 'self';form-action 'self';");
httpResp.addHeader("Expect-CT", "max-age=86400, enforce, report-uri=https://"+ httpReq.getHeader("host").trim() +"/bham/user/reportCT");
httpResp.addHeader("Feature-Policy", "vibrate 'none'; geolocation 'none';");
httpResp.addHeader("Referrer-Policy", "no-referrer-when-downgrade");
System.out.println("Response Headers: "+((HttpServletResponse) response).getHeaderNames());
}
@Override
public void destroy() {
}
}

Любая помощь будет принята с благодарностью.
Я использую tomcat 9 и добавил ниже сопоставление фильтров в сети. xml. Это единственный добавленный фильтр.

Когда я выполняю URL, это то, что я вижу в журналах catalina. Заголовки, которые я добавил, отсутствуют.
