我想要达到的结果

帮忙解决一下 可以有偿

一般跨域请求在servlet过滤器中不是应该这样写的吗

 HttpServletRequest httpServletRequest=(HttpServletRequest)request;
        HttpServletResponse httpServletResponse=(HttpServletResponse) response;
        httpServletResponse.setHeader("Access-Control-Allow-Origin","请求跨域地址如http://baidu.com");
       httpServletResponse.setHeader("Access-Control-Allow-Credentials","true");
        //支持post请求
        httpServletResponse.setHeader("P3P","CP=CAO PSA OUR");
        if("OPTIONS".equalsIgnoreCase(httpServletRequest.getMethod())) {
            httpServletResponse.setHeader("Access-Control-Allow-Headers", "Content-Type,Origin,Accept");
            httpServletResponse.setHeader("Access-Control-Allow-Methods", "POST,GET,HEAD,PUT,DELETE,TRACE,OPTIONS");
            httpServletResponse.setHeader("Access-Control-Max-Age","18000");
        }
        chain.doFilter(request,response);
    }
