点击劫持：X-Frame-Options未配置

解决方案：设置X-Frame-Options参数即可
具体操作步骤如下：
在上面filter基础上添加即可解决

httpResp.addHeader("x-frame-options","DENY");

附上源码：

package com.sinosoft.fis.util;

import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

/**
 * 功能描述:
 * <p>
 *   1.Cookie 设置 httpOnly属性 Cookie 
 *   2.设置 httpOnly属性防止js读取cookie
 * </p>

public class CookieHttpOnlyFilter implements Filter {

  public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
      throws IOException, ServletException {
    if (!(request instanceof HttpServletRequest)) {
      chain.doFilter(request, response);
      return;
    }
    HttpServletRequest httpReq = (HttpServletRequest) request;
    HttpServletResponse httpResp = (HttpServletResponse) response;
    Cookie[] cookies = httpReq.getCookies();
    if (cookies != null) {
      Cookie cookie = cookies[0];
      if (cookie != null) {
        HttpSession session = httpReq.getSession();
        if (session != null) {
          String sessionId = session.getId();
          // http设置
          httpResp.addHeader("Set-Cookie", "JSESSIONID=" + sessionId + "; Path=/fis; HttpOnly");
          httpResp.addHeader("x-frame-options","DENY");
//          httpResp.addHeader("x-frame-options","SAMEORIGIN");
          // https设置
//                      httpResp.addHeader("Set-Cookie", "JSESSIONID=" + sessionId
//                              + "; Path=/admin;Secure; HttpOnly");
        }
      }
    }
    chain.doFilter(httpReq, httpResp);

  }

  public void destroy() {
  }

  public void init(FilterConfig filterConfig) throws ServletException {
  }

}
